Restoring independency with an osteochondral graft of the navicular for coronoid process reconstruction.

INTRODUCTION: The coronoid is a crucial element for elbow stability. In case of posttraumatic instability or reduced range of motion, a complex reconstruction might be necessary.

CASE: We present the case of a polytraumatized patient with complex upper extremity injury and initial poor outcome. Subluxation after initial surgery was treated by sublime tubercle reconstruction with a corticocancellous iliac crest graft. Due to massive ossification, the elbow remained stiff and the paraplegic patient was unable to use a manually propelled wheelchair. After arthrolysis, the unstable elbow was treated with an osteocartilaginous graft from the navicular of the foot as well as ulnar and radial collateral ligamentoplasties. At the time of follow-up, the patient had a stable joint and was able to independently perform activities of daily living.

CONCLUSION: An autologous navicular graft seems to be an excellent option for our paraplegic patient as the shape matches the sublime tubercle of the ulna.
