Swelling and tenderness over the dorsal ulnar wrist frequently present in hamate body fractures.[1]. Although pain and function have improved with conservative treatment 6 months following the injury, he still reports difficulty with his golf game. Of total injuries, 96% were due to hitting, 86% occurred on the nondominant hitting side, and 89% were acute fractures (11% were nonunion cases). doi: 10.1016/j.jhsa.2019.07.015.

The hamate bone is one of eight carpal bones, it is a triangular bone, composed of a body and a hook (hamulus), located on the ulnar side of the distal carpal row. The vascular anatomy of the hamate hook has been extensively evaluated.17 Vessels penetrate the radial base as well as the ulnar tip with relatively poor vascular anastomoses between the two.7,17 This resultant vascular watershed predisposes even nondisplaced hook fractures to nonunion.1,17,18, Hook of the hamate fractures account for only 2% to 4% of all carpal fractures.1 Athletes participating in stick-handling sports account for the vast majority of these injuries and are most at risk of long-term complications secondary to missed or delayed diagnosis.1,2,19,20 The mechanism of injury is either (1) direct. Acute, nondisplaced: Immobilization, six-week cast. Treatment for a hook of hamate fracture depends on the severity of the injury.

The small size of the fragment and precarious vascular supply adds complexity and uncertainty to this procedure.1,10 Thus, excising the fractured hook remains the gold standard among operative procedures.1,24,25 A volar approach is used, with care to identify and protect the surrounding neurovascular and tendinous structures. Indications for surgery include (1) displaced fractures, (2) fractures accompanied by ulnar nerve paresthesias or tendinous pathology, (3) fractures diagnosed later than 7 days from injury, and (4) athletes unwilling to undergo prolonged immobilization of acute injuries.1,17,24 Open reduction and internal fixation have been described.
