Fracture of the Body of the Hamate With Dorsal Dislocation of the 4 and 5 Metacarpals: A Case Report

BACKGROUND: Solitary fractures of the body of the hamate are rare. Their diagnosis is difficult and requires a high clinical suspicion and a proper radiological examination. CASE REPORT: We present a case of a 36-year-old male patient who sustained an intraarticular fracture of the body of the hamate along with dorsal dislocation of the 4th and 5th metacarpals on his right dominant hand. Through a dorsal surgical approach, he underwent ORIF of the hamate with screws and stabilization of the dislocated 4th and 5th metacarpals with KW. At his last follow-up appointment, 18 months postoperatively, he had no pain, almost full range of motion on his fingers and a Mayo Wrist score of 90 points. CONCLUSIONS: Hamate fractures are rare entities that can cause significant patient morbidity if not recognized and treated appropriately.
