Abstract

Background Subluxation of the extensor carpi ulnaris (ECU) tendon can be a challenging problem to the surgeon, with no options described for failure following autologous reconstruction. It is our intention to provide guidance on technique by describing our experience in a 20-year-old male with Ehlers–Danlos syndrome.

Case Description The patient presented with pain and snapping of the ECU tendon, and failed both immobilization and ECU reconstruction with autologous extensor retinaculum. A gracilis tendon allograft was used to reconstruct the ECU sheath, in addition to ulnar groove deepening. At 1-year follow-up, the patient had no pain and the ECU was stable without recurrent subluxation.

Literature Review To the authors' knowledge, the use of tendon allograft for stabilization of recurrent ECU subluxation following surgical repair or reconstruction has not been previously described in the medical literature.

Clinical Relevance Utilization of tendon allograft is a viable technique to stabilize the ECU tendon while minimizing the risk in relying on compromised autologous tissue. This report represents the first account of successful reconstruction following failed autologous reconstruction.
