Progressive surgical release of a posttraumatic stiff elbow - Technique and outcome after 2-18 years in 46 patients

We treated 46 consecutive patients (47 elbows) suffering from posttraumatic contracture of the elbow joint with operative release. A lateral approach was used to perform a capsulectomy after release of the extensor muscles in 23 elbows. An additional medial approach was used to excise ulnar adhesions and perform a more extensive capsulectomy and an ulnar nerve neurolysis in 24 elbows. Postoperative rehabilitation consisted of immediate passive range-of-motion exercises. The results were assessed after average 10 (2-18) years. Before surgery, the mean active arc of motion was 45 (SD 36) degrees, which improved to 99 (SD 34) degrees after release. 7 patients had transient ulnar paresthesia, 4 recurrent stiffness, which did not become worse after surgery, 1 was reoperated on and 2 developed a postoperative infection, which responded to antibiotic treatment after a few months. No patient suffered from joint instability, or an increase in pain. 44 patients were satisfied with the result at the latest follow-up. We found similar improvement in both treatment groups.
