We report a case of a locked thumb metacarpophalangeal joint secondary to metacarpal head fracture. As fractures of the radial condyle are not readily seen in routine X-rays, other imaging modalities, including CT, should be considered if the patient complains of limited extension after hyperextension injury of the thumb.

Key Words: locked MP joint • thumb • hyperextension injury • dorsal dislocation • intraarticular fracture
