Injuries to the hand and wrist are common sports injuries. 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. ⋯ 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.

Osseous injuries to the ulnar aspect of the carpus are increasing in frequency because of greater participation in sporting activities. Hamate body fractures are subdivided into coronal, sagittal oblique, proximal pole, and medial tuberosity fractures. ⋯ 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.

Review Case Reports[Coronal fracture dislocation of the hamate and the base of the fourth metacarpal bone: a rare form of carpometacarpal injury].
Fractures of the hamate body and the base of the fourth metacarpal bone in the coronal plane with or without a dislocation of the base of the fifth metacarpal bone are rare. Clenched fist punches are considered to be the main cause. The diagnosis of the fracture dislocation is often missed on routine radiographs. ⋯ Screw or K-wire fixation with postoperative cast immobilisation for 6 weeks and consecutive hardware removal has been found to result in excellent clinical and radiological outcomes. This study presents 2 cases of coronal fractures of the body of the hamate and the base of the fourth metacarpal bone with subluxation of the hamatometacarpal V joint. Anatomy, epidemiology, classification, mechanism, clinical symptoms, diagnostic features, and therapy options for these injuries are discussed.
