Simultaneous proximal interphalangeal joint arthroplasty and extensor tendon reconstruction in adjacent fingers: case report.

We present a case of a young man with heavily injured proximal interphalangeal joints and deficits of the extensor mechanism in 2 fingers treated by silicone proximal interphalangeal joint arthroplasty and 2-stage reconstruction of the extensor mechanism. The postoperative result was satisfactory with a painless, if limited, active arc of motion of the proximal interphalangeal joints of 50° in the middle finger and 35° in the ring finger.
