title: Double lateral band transfer for treatment of traumatic hyperextension instability of the proximal interphalangeal joint: a report of two cases.
abstract: Post-traumatic hyperextension instability of the proximal interphalangeal joint may lead to pain, difficulty with initiating finger flexion, and a swan-neck deformity. Most techniques to correct a traumatic hyperextension deformity of the proximal interphalangeal joint require a window in the flexor retinaculum, retraction of the flexor tendons, and manipulation of the joint capsule with a conceivable potential for joint stiffness, tendon adhesions, and tendon bowstringing. We describe an extra-articular lateral band transfer technique that utilizes strips of both lateral bands and preserves the functional integrity of the flexor tendon sheath.
