Debridement arthroplasty for post-traumatic stiff elbow: intraoperative factors affecting the clinical results of surgical treatment.

BACKGROUND

This study evaluated the outcomes of debridement arthroplasty for stiff elbows, as well as the factors affecting clinical outcomes after surgical treatment.

METHODS

Eighteen patients with post-traumatic stiff elbows were treated with debridement arthroplasty using a posterior approach. The mean patient age was 33 years (range, 16 to 59 years), and the average follow-up period was 59 months (range, 24 to 141 months). The patient's ability to perform activities of daily living, including combing their hair, feeding themselves, performing hygiene, and putting on shirt and shoes, were evaluated using the Mayo Elbow Performance Score.

RESULTS

At the last follow-up, 16 elbows had painless motion. Two patients continued to complain of mild intermittent pain. The flexion and extension improved to 121 degrees and 10 degrees after surgery, respectively, indicating an average 34 degrees increase in elbow flexion range and an average 25 degrees increase in elbow extension range (p < 0.001, p < 0.001). The Mayo Elbow Performance Score at the last follow-up was excellent in nine elbows (50%) and good in nine elbows (50%).

CONCLUSIONS

Debridement arthroplasty is a predictable procedure for the treatment of intractable stiff elbow, provided that the elbow is stable and congruous.
