Ultrasound treatment was started at three, four, and six months after injury and ultrasound exposure at the hook of the hamate in the hypothenar eminence was carried out for four to five months. During the management period, there was no immobilisation with a cast or brace and limited strain with only routine daily activities allowed. In all cases, bony union was confirmed on carpal tunnel radiographs or computed tomography at the final follow-up time of eight and 36 months after injuries.

Methods: We retrospectively analyzed 161 consecutive patients with 170 distal radius fractures who were treated between 2007 and 2011. Posteroanterior, lateral, and oblique radiographs of the wrist were examined, as were computed tomography scans when available. We evaluated the incidence and characteristics of carpal fractures occurring concurrently with distal radius fractures and the patient factors of gender, age, AO/ASIF classification, and energy of the injury. Results: Of the 170 distal radius fractures, 11 (7%) also had 1 or 2 carpal fractures. Of the 15 carpal fractures, 8 were scaphoid, 2 triquetrum, 2 pisiform, 1 capitate, 1 trapezium, and 1 hamate. Eleven of the 15 carpal fractures were diagnosed by computed tomography alone. Male gender, patients of lower mean age, AO/ASIF type B, and high-energy trauma significantly raised the risk of simultaneous fractures of the distal radius and carpals. Conclusions: The incidence of carpal fractures occurring concurrently with distal radius fractures was not negligible, and almost all carpal fractures had no or minimal displacement. Suspicion of carpal fractures occurring concurrently with distal radius fracture should be high, and computed tomography should be considered, in males, young patients, and those with AO/ASIF type B fractures and high energy trauma. © 2012 American Society for Surgery of the Hand.

The presence of a concomitant hook of hamate fracture is of particular relevance given that it is often occult on routine wrist/scaphoid radiographs and that hook of hamate fractures are prone to symptomatic non-union, resulting in chronic ulnar wrist pain. Prompt diagnosis and immobilisation/fixation may minimise such complications. Our study is aimed at assessing the frequency of concomitant hook of hamate fractures in patients with scaphoid fractures. Methods: Hook of hamate fracture is often occult on wrist/scaphoid radiographs. Hence, we identified all 2,568 CT and MRI studies performed to investigate scaphoid fracture at our institution from April 2005 to March 2016. Three hundred and twelve out of 2,568 cases were confirmed to have a scaphoid fracture. Images were then retrospectively reviewed by a Consultant Musculoskeletal Radiologist and Musculoskeletal Radiologist Trainee to assess for the presence of concomitant hook of hamate fracture and, if present, whether this was identified on initial reporting. Results: Concomitant hook of hamate fracture was identified in 10.3% of cases (32 out of 312, 30 on CT, 2 on MRI); most were minimally/non-displaced. Sixty percent of fractures identified on CT were missed on the initial review (18 out of 30). Both cases identified on MRI had been initially reported. Conclusion: Scaphoid fracture is associated with higher than expected rates of concomitant hook of hamate fracture. Given the potential morbidity associated with hook of hamate fracture, this should be considered a review area when investigating scaphoid injury. These fractures are often minimally displaced, hence easily overlooked on CT. MRI may therefore be superior when investigating radiographically occult scaphoid fractures.

Methods: Radiographs of 3,218 hands (2,070 patients) were evaluated. This group included 2,866 hands diagnosed with CTS and 352 hands without the diagnosis of CTS. Using the carpal tunnel view variations of the hook of hamate were identified. Variants were classified based on appearance and measurements. Patients having variant hooks of hamate who were diagnosed with CTS then were compared with patients with variant hooks of hamate who had no evidence of CTS. Endoscopic carpal tunnel release using the Chow technique was performed on all patients with CTS who had a known variation of the hook of hamate without difficulty or complication. Results: Variations of the hook of hamate were found in 96 hands: 42, bipartite hook; 50, hypoplastic hook; and 4, aplastic hook. Ninety-three hands with variant hooks of hamate were diagnosed with CTS. The remaining 3 hands identified with variants had no evidence of CTS. After comparing the 2 groups, we found that the incidence of a variant hook of hamate in the group with CTS was significantly greater than the incidence of variations in the group without CTS. Conclusions: Three variations of the hook of hamate were identified with radiographic evaluation using the carpal tunnel view. Variations are more prevalent than once thought. There was a significant increase in the incidence of variation in the hook of hamate in the group with CTS compared with the group without CTS.

Methods: A retrospective chart review was performed on Major and Minor League Baseball players who underwent surgical excision for the hook of hamate fracture between the years 2003 and 2019 by a single surgeon. Patient demographics, the mechanism and timing of the injury, diagnostic and operative details, postoperative complications, and timeline to return to baseball activities were recorded. Results: A total of 145 professional baseball players affiliated with 17 Major League Baseball organizations were studied, with the majority of athletes playing at the Minor League Baseball level (91.7%). Subacute or chronic patterns of injury (81.7%) were found to be more common than acute patterns based on radiographic and intraoperative findings. Two patients reported transient numbness in the fourth and fifth digits after surgery, 6 patients reported pisotriquetral pain when returning to a hitting program, and 1 patient developed heterotopic ossification after surgery. All complications resolved during a strength and conditioning program. On average, players in our cohort began a hitting program at 4.6 weeks after surgery and were released into full baseball activities at 7.1 weeks after surgery. Conclusions: Surgical excision remains an effective method of management, with a low risk of minor complications for both acute and chronic hook of hamate fractures in professional baseball players. Type of study/level of evidence: Therapeutic Level IV.

The objective of this study was to evaluate the outcomes of distal radius fractures treated with radial column plates. Methods: A consecutive series of 61 patients who sustained distal radius fractures underwent radial column plating alone or in conjunction with other implants between August 2006 and January 2014. Thirty-one patients returned for follow-up or returned a mailed questionnaire at an average of 4.1 years. The outcomes measures included Visual Analog Scale (VAS); Disabilities of the Arm, Shoulder and Hand (DASH); and Patient-Rated Wrist Evaluation (PRWE) scores. Results: Sixty-one patients with a mean age of 55 years (range, 20-87) met inclusion criteria and were available for follow-up or chart review at an average of 5.2 years (range, 1.6-9.0 years). Seventeen of 61 (28%) underwent radial column plate removal. Twenty patients returned for final follow-up examination, and 11 completed questionnaires via mail. Subjective scores included a mean postoperative VAS of 0.72, DASH score of 17.2, and PRWE score of 15.7. Hardware sensitivity and wrist stiffness were the most common complications at final follow-up. Conclusions: Radial column plating of the distal radius is a safe treatment modality and a valuable adjunct in the setting of complex distal radius fractures, but patients should be counseled that there is a 28% chance that hardware removal may be required. Our retrospective review found evidence of few complications and objective scores consistent with return to normal function. AU - Chung, K. C. AU - Spilson, S. V. AU - Mauck, Benjamin M.

Diagnosis depends on clinical acuity. The most common symptom is pain in the palm that is aggravated by grasp. Weakness of grasp and dorsal wrist pain are also common. Ulnar nerve paresthesia or weakness and mild carpal tunnel syndrome are frequently present. Tenderness directly over the hamulus is always present, and grip strength typically is diminished. Tenosynovitis, tendon fraying, or tendon rupture may be demonstrated in 25% of the cases and is not related to the use of steroids. Lateral trispiral tomography is clearly superior to the other diagnostic methods. Excision produced generally excellent results, particularly in patients with an athletic injury or with no associated additional injury. A nonathletic injury or the presence of associated trauma adversely affected results. Immediate immobilization of acute fractures may result in fracture healing and obviate operative intervention. Open reduction and internal fixation is feasible but offers little advantage over excision. © 1988. AU - Bishop, Allen T. AU - Beckenbaugh, Robert D.

Hamate body fractures are subdivided into coronal, sagittal oblique, proximal pole, and medial tuberosity fractures. Successful treatment of coronal fractures requires identification and treatment of associated disruption or instability of the ulnar 2 carpometacarpal joints. Displaced hamate hook fractures are optimally treated with early excision to avoid sequelae such as flexor tendon and nerve injury, and to allow early return to activity. Undisplaced pisiform fractures are managed nonoperatively, whereas displaced fractures and nonunions are treated by simple excision. © 2012 Elsevier Inc. AU - O'Shea, Kieran AU - Weiland, Andrew J.

The diagnosis and therapy of wrist injuries are becoming more important, especially in increasingly more popular ball-hitting sports, such as golf, tennis and baseball. Ulnar-sided wrist pain is initially often misdiagnosed and treated as tenosynovitis or tendinitis but tears of the triangular fibrocartilage complex (TFCC) and fractures of the hook of hamate bone, which can also occur in these sports are seldomly diagnosed. The aim of this study was to conduct a systematic review of the literature focussing on TFCC lesions and fractures of the hook of the hamate bone in racquet sports, baseball and golf. A systematic review of the literature was performed in PubMed on the occurrence of TFCC lesions and fractures of the hook of the hamate bone. All studies and case reports were included. Because of the rarity of these injuries there were no exclusion criteria concerning the number of cases. Injuries associated with ball-hitting sports, such as TFCC lesions and fractures of hook of the hamate bone are still underrepresented in the current literature on sports injuries. The diagnosis and treatment of these injuries are often delayed and can severely handicap the performance and career of affected professional as well as amateur athletes. AU - Plöger, M. M.

Usually, those individuals who elect for excision have acute fractures and need to return to sporting activity or work quickly or have nonunions with persistent symptoms. There is a paucity of descriptions in the literature and textbooks of a technique to safely excise the hook of the hamate. The authors present a method of safely exposing and removing the hook of the hamate by visualizing the potential structures at risk: the motor branch of the ulnar nerve, the ulnar digital nerve to the little finger, and the flexor tendons to the ring and little fingers by an approach through Guyon's canal and the proximal ulnar border of the carpal tunnel.

Also, hand and wrist injuries are more common in pubescent and adolescent athletes than adults. Although knee and shoulder injuries are more common athletic injuries, an injury to the hand or wrist significantly can impair the athlete's ability to throw or catch a ball, or swing a bat or racquet. A college football player trains year round for just 11 or 12 hours of playing time. An athletic injury that occurs during the season can have profound consequences for the athlete's career and emotions. When defining a management plan for a particular wrist athletic injury, the time to heal the injury and the time to rehabilitate fully must be considered. The athlete must be informed fully of the length of recovery. The continued advancement of fixation methods and techniques are diminishing fracture morbidity considerably. Small-cannulated compression screws that provide rigid fixation can be inserted with decreased surgical dissection, thus preserving critical vascular supply and promoting accelerated healing and earlier rehabilitation. The arthroscope as a valuable adjunct in the management of wrist fractures was virtually unheard of years ago, but is now common. The ability to arthroscopically guide a cannulated compression screw to stabilize a scaphoid fracture without a formal open volar approach can reduce surgical morbidity significantly and allow the athlete to return to competition more quickly. Mechanisms of injury that cause osseous fractures of the wrist are fairly high energy. A high index of suspicion for associated soft tissue injuries should be kept in mind when fractures of the wrist are identified. The wrist is composed of eight carpal bones tightly interwoven with each other by intrinsic and extrinsic wrist ligaments. The management of carpal fractures depends on prompt diagnosis, stable and anatomic alignment of the involved carpal bone, protective immobilization of the injury, and thorough rehabilitation. Displaced fractures of the hook of the hamate, trapezial ridge fractures, and comminuted pisiform fractures are managed best by early excision to promote uncomplicated recovery and early return to sport. For most athletes, return to competition can be expedited safely with the use of padded gloves and custom playing splints or casts.7, 10 The sports medicine physician always must put the athlete's safety first when deciding the appropriate time for return to competition.

Minimal invasive fixation using a dorsal percutaneous approach and a headless cannulated mini-screw is another option not commonly considered. The authors present their case series of patients who underwent dorsal percutaneous fixation of acute fractures and delayed union of the hamate hook. This study retrospectively reviewed six consecutive patients (five male patients and one female patient) with non-displaced acute fractures (< 8 weeks) and delayed union (8 to 12 weeks) of the hamate hook treated with dorsal percutaneous cannulated mini-screw fixation. The indications for surgery included wrist pain, patient refusal of conservative treatment, and prevention of non-union and hook excision. Exclusion criteria included displacement or inadequate size of the hamate hook, previous surgery, associated carpal injury, flexor tendon rupture, and median or ulnar nerve lesion in the carpal tunnel and Guyon's canal respectively. Each fracture was visualized by radiography and computed tomography before and after the intervention. Anatomically correct fixation of the hamate hook with central screw positioning was achieved in all patients. No displacement or disruption of the cortical shell of the hook was observed. The union rate was 100% with all patients being able to resume their pre-injury activities after an average of seven weeks from surgery. This pilot study demonstrates that non-displaced acute fractures and delayed union of the hamate hook can be treated successfully by dorsal percutaneous cannulated mini-screw fixation with minimal morbidity and complications.

One patients with a subacute fracture did not comply with treatment and had a painful nonunion. Our results show that hamate hook fractures that are diagnosed early may heal with nonoperative management. Fractures that fail to heal with immobilization or those with chronic nonunion should be treated with excision of the hook fragment. © 1992. AU - Whalen, Joseph L. AU - Bishop, Allen T.

The open carpal tunnel approach is another option, which has not previously been commonly considered and not reported in a peer review journal. Our study aims to highlight the carpal tunnel approach as a successful technique in a consecutive series of ununited hook of hamate fractures. Patients and methods: Seven patients (all male and mean age 30.7 years) were reviewed with symptomatic ununited fractures following a period of cast immobilization. All the patients operated on underwent excision of the hook of hamate fragment via the open carpal tunnel approach. Results: All patients successfully returned to their pre-injury level of functioning after 8-12 weeks and there were no complications. Conclusions: Our study highlights the open carpal tunnel approach as a successful technique for open excision of symptomatic ununited hook of hamate fractures, because of its familiarity, ease of performance, excellent visualization and low morbidity.

Treatment was either conservative or operative and was decided according to the degree of fracture displacement and presence of carpometacarpal subluxation. Patient follow-up was 14.8 months on average, using DASH scores and postoperative radiographs to determine functional and anatomical outcomes. Undisplaced fractures were treated in a cast with good outcome. Postoperative radiographs of patients treated with Kirschner wires for displaced fractures showed incomplete reduction and the outcomes were less favourable. Rigid internal fixation gave excellent radiographic results, although these did not correlate with functional outcome in all patients. © 2010 The British Society for Surgery of the Hand.

Many of these injuries are sports related, particularly in golf, tennis, racquetball and baseball players. Failure to make an early diagnosis can result in severe pain and sometimes incapacitating disability. We studied the clinical and radiological findings in 12 patients who had fracture of the hook of the hamate. We propose three radiographic signs of fracture that are readily seen on routine PA projections: 'absence' of the hook of the hamate; 'sclerosis' of the hook; and lack of cortical density, i.e., a barely visible outline, of the hamulus.

The two main types of hamate fractures are hook fractures (type 1) and body fractures (type 2). We sub-divided type 2 fractures according to the fracture line into coronal, type 2a and transverse, type 2b. There were 15 type 1, 11 type 2a and three type 2b fractures. For type 1, nine were treated with excision, one with open reduction and internal fixation (ORIF) and five with cast immobilisation, in which two resulted in non-union followed by excision. For type 2, five type 2a cases were treated with ORIF and the others with closed reduction and pinning. Most of the patients had satisfactory results at the seventh month follow-up. However, those with associated neurovascular and musculotendinous injuries were likely to have unfavourable results. On the basis of study findings, it appears that functional results are influenced mainly by the associated soft tissue damage.

Eleven patients (two with fresh fractures and nine with nonunion) were studied. The fractures were diagnosed with HHPT for recently encountered 4 patients and a definitive diagnosis was made by a carpal canal view and a computed tomography (CT) scan. Treatment involved cast immobilization for one fresh fracture case, and bone fragment removal immediately over the hook for ten others. HHPT was positive in all the four cases. Union was achieved by conservative treatment, and hypothenar pain disappeared after surgery. Patients returned to work/sports two months postoperatively. HHPT was useful for diagnosing both fresh fractures and nonunion. If HHPT is positive, CT should be performed even if the fracture is obscure on a carpal canal view.

Purpose: To describe a previously unreported condition in which the fractured hook of the hamate unites only along its ulnar column and causes pain similar to that in cases of nonunion. Study Design: Retrospective review. Methods: Eight patients who had sustained a hook of the hamate fracture were identified, on the basis of their persistent pain, as having achieved only partial union. This diagnosis was made despite evidence on computed tomography of healed bone across a significant portion of the fracture. All eight patients underwent subperiosteal excision of the hamulus because of persistent pain. At an average of 4 years after excision, each patient was evaluated by dynamometer grip strength testing and a subjective outcome assessment. Results: All patients were able to return to their preinjury level of sports participation at an average 8 weeks after excision of the hook of the hamate. Grip strength was not adversely affected in any patient. Subjective evaluation of each patient revealed no residual pain. Conclusions: Chronic or unresolved pain on the ulnar side of the wrist after hook of the hamate fracture can be due to partial union. This condition should be managed no differently from a symptomatic nonunion, with excision of the hook of the hamate and repair of the ligament attachments. © 2003 American Orthopaedic Society for Sports Medicine.

These can be divided into two categories: traumatic injuries and overuse injuries. The aim of this article is to review the most common hand and wrist sports-related lesions. Acute wrist injuries are predominantly bone fractures, such as those of the scaphoid, hamate hook, and ulnar styloid. Ligament lesions are more challenging for radiologists and may lead to carpal instability if undiagnosed. Overuse wrist injuries are mainly represented by tendinous disorders, with De Quervain syndrome and extensor carpi ulnaris tendon disorders being the most common among them; however, there are other possible disorders such as impaction syndromes, stress fractures, and neurovascular lesions. Finally, finger lesions, including closed-tendon injuries (mallet and boutonniere injuries, jersey finger, and boxer's knuckle), flexor pulley injuries, and skier's thumb, should also be detected.

Methods: We evaluated 11 patients representing 12 cases of hook of hamate excision. All patients were high-level amateur athletes (rising collegiate or collegiate level). We performed a retrospective chart review to elicit information pertaining to the patient's injury. We assessed long-term postoperative outcomes with a self-reported questionnaire, the DASH form, and the DASH Sport/Performing Arts Module form. Results: All patients successfully returned to full participation in their respective sports an average of 6 weeks after surgery. The average postoperative DASH score was less than 1, and all patients scored a 0 on the DASH Sports form. There was a significant improvement in preoperative pain after surgical intervention. There was no significant difference between preinjury and postoperative performance scores. Finally, every patient was very satisfied with the surgical outcome. There was only 1 postoperative complication in which a patient developed transient ulnar nerve paresthesias, which completely resolved by 6 weeks after surgery. Conclusions: Surgical excision of hook of hamate fractures in high-level amateur athletes allows for successful return to sports participation at preinjury performance levels, achievement of normal function as measured by validated objective outcome measures, significant reduction in pain, and high overall patient satisfaction. We consider surgical excision to be a safe and effective technique to restore normal function and hasten return to play for high-level amateur athletes.

Fractures of the hook of hamate have been known to occur in batters. The purpose of this study is to present our experience with the surgical management of hook of hamate fractures and their short-term impact on the playing capability of competitive baseball players. Methods: A retrospective chart review was performed on patients with hook of hamate fractures between the years 2000 and 2012. The inclusion criteria were (1) hook of hamate fracture, (2) competitive baseball players, and (3) surgical treatment of the injury. Patient demographics, mechanism of injury, surgical treatment, and outcome were collected from the medical records. Information on return to play was collected from the Internet when applicable. Results: There were seven male patients that underwent eight procedures. The mechanism of injury was attributed to batting in six cases and rogue pitches in two cases. All surgeries consisted of hamate hook excision and ulnar tunnel decompression. One patient had concomitant carpal tunnel release. The median time between surgery and return to play was 5.7 weeks (range, 4.3 to 10.4 weeks). Conclusions: The mechanism of hook of hamate fractures in baseball players is predictable, most often developing secondary to repetitive swinging. This injury may occur at all levels of competition. Ulnar tunnel decompression with hook of hamate excision provides good outcomes, with minimal complications and early return to play. © 2013 American Association for Hand Surgery.

According to the fracture sites and the prognosis, we classified the hamate hook fractures into 3 types. Type I referred to an avulsion fracture at the tip of hamate hook, type II was a fracture in the middle part of hamate hook, and type III represented a fracture at the base of hamate hook. By the classification, in our series, only 1 fell into type I, 7 type II, and 4 type III. The results were evaluated with respect to the functional recovery, recovery time and the association among the clinical classification, pre-operative complications and treatment results. The average follow-up time of this group was 8.4±3.9 months. Two cases were found to have fracture non-union and both of them were type II fractures. Six patients had complications before operation. Five cases were type II fractures and 1 case type III fracture. All the patients were satisfied with the results at the time of the last follow-up. Their pain scale and grip strength improved significantly after treatment. All the pre-operative complications were relieved. The recovery time of hamate hook excision was significantly shorter than that of the other two treatments. The incidences of both pre-operative complications and non-union in type II fractures were higher than those in type I and type III fractures. It was concluded that, generally, the treatment effects with hamate hook fracture are quite good. The complication incidence and prognosis of the fracture are closely related to the clinical classification. Early intervention is critical for type II fractures. AU - Xiong, G.

We analysed the relationship between the fragment height ratio, fragment gap, and intraoperative findings of the tendons. We determined whether parameters in the images can predict complication of tear or disruption of the flexor tendons to the ring or little fingers. Of 28 patients, 16 had fragment height ratios between 50–74; ten among them had worn (eight patients) or ruptured (two patients) flexor tendons. Nine of the ten patients had fragment gaps greater than 2 mm. The remaining 12 patients had fragment height ratios between 75–100 and had intact tendons. We conclude that a fragment height ratio greater than 75 and fragment gap less than 2 mm in computer tomography may rule out tear or disruption of the flexor tendons of the ring and little fingers after hamate hook fractures, and a fragment height ratio between 50–74 with fragment gap greater than 2 mm indicates a high risk of flexor tendon tear or disruption.

We performed a retrospective study of 51 patients treated for hook of hamate fractures. Patients were sent a quickDASH questionnaire regarding the outcomes of their treatment. Hook of hamate fractures were diagnosed with advanced imaging at a median of 27 days. Clinical findings of hook of hamate tenderness had better sensitivity than carpal tunnel-view radiographs. Nonunion occurred in 24% of patients with non-operative treatment and did not occur in the operative group. Both treatment groups achieved good clinical results, with a grip strength of 80% compared with the non-injured hand and a median quickDASH score of 2. Advanced imaging improved the time to diagnosis and treatment compared to historical case series. Nonunion is common in patients treated non-operatively. Level of evidence: IV.

Methods: We report the outcomes of ORIF of hamate hook fractures in 13 consecutive patients (12 men and 1 woman; mean age: 32 years (range, 22–48 years)). In eight patients (61%) the fracture was associated with ulnar nerve neuritis in Guyon's canal. We assessed the following clinical data: age, sex, mechanism of injury, side of the injured hand and associated lesions, fracture classification, average time from injury to correct diagnosis, surgical technique, complications, and length of follow-up. All patients underwent radiological imaging, including standard radiographs in two planes (anteroposterior and lateral projections), and a CT study. Functional outcomes evaluated were pain, range of motion, grip strength, Disabilities of the arm, shoulder and hand (DASH) and Mayo wrist score. Results: The mean follow-up was 36 months (range, 12–144 months). All 13 cases were treated with ORIF of the hook of the hamate. Mean VAS pain score was 5 preoperatively (4–9) and 1 (0–2) postoperatively. All patients returned to pre-injury level and only one patient felt pain on activity. Preoperative modified Mayo wrist score was 51 and the postoperative value was 94. All outcomes scores improved significantly from preoperative values. The patients who participated in sports postoperatively were able to do so at or near pre-injury levels. Postoperative average range of wrist motion was 76° in extension, 71° in flexion, 14° in ulnar deviation, and 21° in radial deviation. Mean grip strength in the hand with the hook fracture was 58 kg compared with 53 Kg in the unaffected hand. All patients returned to their pre-injury level of functioning after 10–12 weeks and there were no complications. Analysis of grip strength revealed values comparable with the unaffected hand. Conclusion: ORIF of hamate hook fractures is a safe and effective technique to restore normal grip strength and return to pre-injury level. In cases of ulnar nerve neuritis, neurolysis of the deep palmar branch is mandatory. Level of evidence: Level IV, Therapeutic study.

Is this surgical treatment necessary? T2 - Acta Orthopaedica et Traumatologica Turcica VL - 53 ER - TY - JOUR AB - The treatment of choice in nondisplaced hook of hamate fractures is conservative, with lower arm splinting. Displaced fractures should be treated operatively, whereby excision of the fragment or open reduction and internal fixation are described. A hamulus ossis hamati fracture was verified in 14 patients (mean age, 42 years; range, 21 to 73 years) including 11 men and three women. In six patients (42.9 percent), conservative treatment was initiated immediately after trauma with a lower arm cast for 6 weeks, and eight patients (57.1 percent) were operated on primarily. In five patients (35.7 percent), the fragment was excised, and in three patients (21.4 percent), an open reduction and internal fixation was performed using a screw. In five of six patients treated conservatively, nonunion of the fracture with persisting clinical symptoms developed. All of those patients were treated operatively, whereby three patients underwent excision and two patients underwent screw fixation, which led to elimination of the symptoms. One patient was asymptomatic despite non-union of the fracture and rejected surgery. All of the eight patients operated on primarily were asymptomatic 3 months after surgery. Therefore, the success rate of primary surgical treatment (eight of eight) was significantly higher compared with conservative treatment (one of six). Finally, all 14 patients were asymptomatic at late postoperative follow-up. The clinical outcome of patients with hook of hamate fractures treated conservatively was disappointing. Therefore, primary surgical treatment is recommended. In our patients, excision and open reduction and internal fixation led to comparable results.

Material and method: We retrospectively reviewed 10 patients treated in our clinic between 2005-2012 suffering from fractures of the hamate. Six cases were fractures of the body and four were fractures of the hamate. Five cases were of associated injuries. Diagnostic delay ranged from 30 days to 2 years. Patient follow-up ranged from 1 to 10 years. Patient satisfaction was evaluated using the DASH questionnaire. Five patients with a fracture of the body underwent surgery, and one was treated conservatively. Two patients with fracture of the hook of the hamate were treated with immobilization, and two more patients had the fragment removed. Results: The grip strength and the digital clip were reduced in 2 cases. Flexion and extension of the wrist was limited in 3 cases. The mobility of the fingers was normal in all the cases, except in one. The results obtained from the DASH questionnaire were normal in all the cases, except in one case of fracture of the hamate, and in two cases of fracture of the body. Conclusions: The surgical treatment should reduce the dislocation and stabilize the injuries with osteosynthesis. The fractures of the hamate are usually diagnosed late, and the most recommended treatment is removal of the fragment, although it cannot be deduced from this study. AU - Sarabia Condés, J. M.

The fracture is rarely diagnosed on routine wrist radiographs, thus generally requiring CT or MR for diagnosis. Surgical excision has a high success rate, however diagnostic delay contributes to a high complication rate. Radiographic signs of hook of hamate fracture have been published, but uncertainty of the diagnostic accuracy limits application. The purpose of this study is to determine accuracy and interobserver reliability of radiographic signs of hook of hamate. Materials and methods: This retrospective case-control study evaluated wrist radiographs of 50 patients, including 24 positive and 26 negative, for hook of hamate fracture, each proven by CT or MR. Five reviewers performed blinded, randomized evaluation of radiographs documenting whether the hook of hamate was normal or fractured, and if fractured, the radiographic signs present (ring sign, ghostly shadow, and diffuse sclerosis) and views that contributed to diagnosis. Results: Radiographic signs demonstrated high sensitivity (85%; 95% CI: 77–91), specificity (92%; 95% CI: 86–96), and accuracy (89%; 95% CI: 84–92) with substantial interobserver reliability (k = 0.652). The ring sign was the most sensitive radiographic sign. Diagnosis was most often supported by the oblique view (38%) and rarely the lateral view (15%). Conclusions: Radiographic signs of hook of hamate fracture on routine radiographs can accurately and reliably diagnose hook of hamate fractures. Evaluation for discontinuity of the cortical ring will optimize sensitivity, allowing for timely diagnosis and treatment, and a reduction of complications. AU - Spencer, Jayden AU - Hunt, Suzanne L.

The purposes of this article are to review hook of the hamate anatomy, describe the imaging features of the spectrum of pathologic conditions, and discuss the pearls and pitfalls of imaging for clinical decision making for pathologic entities affecting the hook of the hamate. CONCLUSION. Knowledge of the anatomy, imaging appearance, and clinical management of hook of the hamate abnormalities is important for radiologists in guiding the care of patients with ulnar-sided wrist symptoms.

The presence of a concomitant hook of hamate fracture is of particular relevance given that it is often occult on routine wrist/scaphoid radiographs and that hook of hamate fractures are prone to symptomatic non-union, resulting in chronic ulnar wrist pain. Prompt diagnosis and immobilisation/fixation may minimise such complications. Our study is aimed at assessing the frequency of concomitant hook of hamate fractures in patients with scaphoid fractures. Methods: Hook of hamate fracture is often occult on wrist/scaphoid radiographs. Hence, we identified all 2,568 CT and MRI studies performed to investigate scaphoid fracture at our institution from April 2005 to March 2016. Three hundred and twelve out of 2,568 cases were confirmed to have a scaphoid fracture. Images were then retrospectively reviewed by a Consultant Musculoskeletal Radiologist and Musculoskeletal Radiologist Trainee to assess for the presence of concomitant hook of hamate fracture and, if present, whether this was identified on initial reporting. Results: Concomitant hook of hamate fracture was identified in 10.3% of cases (32 out of 312, 30 on CT, 2 on MRI); most were minimally/non-displaced. Sixty percent of fractures identified on CT were missed on the initial review (18 out of 30). Both cases identified on MRI had been initially reported. Conclusion: Scaphoid fracture is associated with higher than expected rates of concomitant hook of hamate fracture. Given the potential morbidity associated with hook of hamate fracture, this should be considered a review area when investigating scaphoid injury. These fractures are often minimally displaced, hence easily overlooked on CT. MRI may therefore be superior when investigating radiographically occult scaphoid fractures.
