Simultaneous dislocation of the interphalangeal joints of the index finger

A crush injury caused simultaneous posterior dislocation of the interphalangeal joints of the index without associated fracture. Orthopedic treatment was used because a stable reduction was achieved without difficulty. The hand was immobilized for three weeks followed by rehabilitation exercises. Complete functional recovery was achieved with pain-free joints. We recommend starting the reduction at the distal interphalangeal level in order to allow relaxation of the deep flexor tendons favoring reduction of the proximal interphalangeal joints.
