Isolated anterior fracture–dislocation of the hamate bone: a case report

Isolated complete dislocation of hamate bone with an ulnar nerve injury: a case report and literature review

“…If the TCL remains intact, the hamate bone may be pulled to the volar side (12). Using direct compression force that is sufficient enough to cause complete dislocation of the hamate bone, we should be vigilant about the possibility of hand tendon compartment syndrome (2,13). Comprehensive analysis of the literature shows that wrist injuries in patients with complete dislocation of the hamate bone are mostly caused by direct violent crushing injuries such as injuries that involve gears and heavy objects, accounting for 56.5% of all cases.…”

“…Additionally, there was visible ulnar wrist bone protrusion or shortening. Attention should be given to the evaluation of nerves (2,(13)(14)(15) or vascular injury. A few patients have acute osteofascial compartment syndrome (2,15).…”

“…In contrast, when the distal end of the hamate bone rotates to the dorsal side, the hamate bone moves to the dorsal side, the transverse carpal ligament is in a high tension state, the carpal tunnel is compressed, and the median nerve is pinched at the same time. High-resolution CT can accurately diagnose hamate bone fracture (12,13,15,16).…”
