Aim: To evaluate the functional and radiographic results of dorsal capsulodesis in predynamic and dynamic scapholunate instability. Methods: Nineteen patients underwent a scapholunate interosseous ligament repair combined with a dorsal capsulodesis as described by Blatt, in as many wrists for scapholunate instability between 1994 and 1999. The diagnosis was based on a clinical, radiographic and arthroscopic assessment. Mean follow up was 22 months (8 months – 5 years). 15 patients were available for follow up. Most (13 of 15) of the patients presented with predynamic or dynamic instability. Results were analysed clinically and radiologically. Results: Thirteen patients showed a good or excellent clinical result. There was a statistically significant improvement in pain relief (VAS scores) and grip strength (58% of the opposite side). Mean extension and ulnar deviation was significantly better (62% and 53% of the opposite side respectively) and there was a significant reduction in wrist flexion (49% of the opposite side). 13 patients returned to their original level of activity. There was no significant change in the mean SL gap and angle after surgery. Thirteen patients would recommend this operation. Conclusions: We thus believe that this procedure can produce encouraging results in cases of pre dynamic and dynamic instability in a patient population with low demand wrists. Larger case loads and more complete follow ups would be desirable to derive strong evidence based conclusions.
