064 OPEN SURGICAL TREATMENT OF THE STIFF ELBOW IN PATIENTS WITH NEUROMUSCULAR DISEASE

Abstract

Elbow contracture is a well recognised sequel of neuromuscular disorders and can be a rather debilitating condition. Non operative treatment, such as physiotherapy and splinting, results in an improved range of motion, but since musculoskeletal pathology in neuromuscular diseases is progressive, an open surgical release of the elbow is often required. Therefore, the purpose of the present study was to assess the results of surgical treatment of elbow stiffness in patients suffering from neuromuscular disorders.

Between January 2000 and October 2008, 11 patients with neuromuscular diseases underwent surgical treatment of elbow contracture. The mean age of the patients was 21 years. Eight patients had cerebral palsy, 2 arthrogryposis and 1 brachial plexus palsy. Pre-operatively the lag of elbow flexion and extension was 45° and 38° respectively. In 6 patients releases were performed through a lateral approach, while 3 required an additional medial incision. In 2 patients the pathology was addressed through a posterior approach.

The mean follow up was 26 months. Postoperatively one patient developed skin necrosis which was treated conservatively. Furthermore, another patient developed transient ulnar neuritis, and finally one more presented with medial collateral ligament insufficiency. All patients had an improved functional arc of motion. Namely, the lag of elbow flexion and extension was reduced to 22° and 10° respectively. At the final follow up the patients maintained 90% of the range of motion that was achieved immediately postoperatively.

Open release of the elbow contracture in neuromuscular diseases yield satisfactory results. Therefore, it can be expected that patients will obtain a functional range of motion.
