Abstract
Extensor tendon subluxation can result from a disruption to the extensor retinacular system and/or the sagittal band at the metacarpophalangeal joint. When conservative treatment is insufficient to correct the subluxation, surgical treatment is necessary and various surgical techniques exist. We present a novel stabilization technique to centralize the extensor tendon using a junctura tendinum to lengthen an extensor digitorum communis tendon graft. This technique is simple and effective, creating a strong repair without associated stiffness. To achieve a less morbid, stable repair, we mimicked normal anatomy with minimal disruption to local soft tissue structures. This technique seems to offer biomechanical advantages over previously described techniques and shows successful treatment in the illustrated patient.
