Abstract
Background
The optimal treatment for symptomatic elbow osteoarthritis remains debatable especially in patients still involved in heavy manual work. The Outerbridge-Kashiwagi (OK) procedure has been used when simple measures fail. The aim of this study is to analyse the results of the OK procedure in patients with symptomatic osteoarthritis.
Methods
Twenty-two patients were included in the study. The male:female ratio was 18:4. The mean age was 60 years with mean follow-up of 38 months (24–60 months). 17 were manual workers, 3 involved in sports activities and 2 non-manual workers. All patients were assessed using Mayo Elbow Performance Index Score system. Preoperative radiological assessment showed osteophytes around olecranon and coronoid process and joint space narrowing in radio-humeral articulationin all cases.
Results
There was a significant improvement (p<0.05) in movement in the flexion-extension axis from 78.2° to 107.3°. There was a significant reduction in pain post-operatively (p<0.001). Mean MEPI score improved from 50 to 87.4 post surgery which was significant (p<0.05). One patient had ulnar nerve palsy which resolved in six months with conservative management. The results were excellent in six patients (27%), good in fifteen (68%), fair in one (5%) and one (5%) had poor result.
Discussion and conclusion
The present study indicates that the OK procedure provides significant pain relief and a functionally useful range of movement of more than 100°. The procedure can be used in high demand patients, wherein total elbow replacement is not indicated. It significantly reduces the disability in patients with significant elbow arthritis.
