Abstract
Triquetrum fracture is a relatively rare injury. We report a case of the triquetrum fracture with cystic lesion after injury. The case was a 53-year-old, male. He fell off his bicycle and injured himself in October 2010. He complained of his left hand pain on the dorsal side. The diagnosis was triquetrum bone cyst with fracture. Due to persistent left hand pain, operation was performed in December 2010. Minimal dorsal approach to the triquetrum was conducted and CPC was injected into the defected area. Pathological examination showed necrotic lesions. The final diagnosis was triquetrum fracture without tumor. Hand pain disappeared three months after operation and there was no functional disorder. We experienced a triquetrum fracture case which represented cyst-like lesion after injury. When damage to the cancellous bone is large, careful investigation for triquetrum fracture is necessary to distinguish it from bone tumor.
