Technique using interference fixation repair for plantar plate ligament disruption of lesser metatarsophalangeal joints.

Lesser metatarsophalangeal joint instability is a challenging disorder for the foot and ankle surgeon to repair. We believe that disruption of the plantar plate is common, and its repair should be carefully considered. However, we believe that most current techniques inadequately address repair of the complete plantar plate ligament tear, and, thus, instability and pain commonly persist after disruption of the plantar plate. In the present report, we present a technique we have found useful for repair of a complete plantar plate ligament rupture. The method we have described uses interference screw fixation through a dorsal incision to stabilize the lesser metatarsophalangeal joint.
