Unusual pattern of dislocation of the trapeziometacarpal joint with avulsion fracture of the trapezium: case report.
Dislocation of the trapeziometacarpal joint is a rare injury. We report an unusual pattern of dorsal dislocation of the trapeziometacarpal joint with an avulsion fracture of the dorsoradial tubercle of the trapezium. Simultaneous ligament rupture with an avulsion fracture of the thumb metacarpophalangeal joint was associated. The trapeziometacarpal joint was reduced and disrupted ligaments with avulsed fragments of both joints were surgically repaired.
