[Long-term results of the modified Eden-Hybinette operation for treatment of recurrent shoulder dislocation].

In a retrospective study we evaluated the long-term results of a modified Eden-Hybinette procedure in 76 patients. Besides stability, function, and subjective complaints, we documented in particular the degenerative changes of the joint. Subjective findings revealed excellent or good results in 68.5% of cases. In 20% of the patients the results were fair and in 11.5% poor. Some 66% of the patients had not subjective feeling of joint restriction. However, 25% complained of some and 9% of severe joint restriction. The overall recurrence rate was 13.9%. In patients with atraumatic dislocation the recurrence rate was 12%, in patient with voluntary dislocation it was 50%, and in posttraumatic instabilities the recurrence rate was 4.8%. The Rowe score showed 40% excellent and good results. The poor results were among the patients with redislocation, instabilities with subluxation, and secondary degenerative joint disease with concomitant pain and limitations in the range of motion. In patients with voluntary instabilities the poor results were in the group of redislocators, whereas in the posttraumatic group poor results were mainly due to degenerative joint disease. In 80% of the patients with bone block complications, secondary degenerative joint disease developed. Considering the relatively high recurrence rate and the amount of secondary degenerative joint disease after this procedure, we do not recommend this as a routine procedure for shoulder stabilisation.
