Tether Creation Between the Second and Third Extensor Digitorum Communis for Third Extensor Tendon Subluxation at the Metacarpophalangeal Joint
We developed a substitution technique for a sagittal band reconstruction for subluxation of the third extensor tendon at the metacarpophalangeal joint. Through this procedure, we attempted to supply a tether between the second and third extensor digitorum communis (EDC) tendons. A half-slip of the second EDC was interlaced to the third EDC tendon at the level of the third metacarpal head with the metacarpophalangeal joint in full flexion position; this ensured that the interlace of the graft serves as a direct stabilizer against ulnar subluxation. A key advantage of our procedure is the strong and reliable interlace of the graft that does not require postoperative immobilization and allows unprotected motion protocol.
