Collateral Ligament Reconstruction of the Proximal Interphalangeal Joint

Abstract

Proximal interphalangeal joint collateral ligament injuries are common; however, chronic instability of this joint is rare. In such cases, however, there is no consensus on optimal management. Various repairs and reconstructions have been devised, although the literature on outcomes remains scant. We present a method of reconstruction of the proximal interphalangeal joint collateral ligament using a distally based slip of the flexor digitorum superficialis tendon.
