In a retrospective study we evaluated the long-term results of a modif
ied Eden-Hybinette procedure in 76 patients. Besides stability, functi
on, and subjective complaints, we documented in particular the degener
ative changes of the joint. Subjective findings revealed excellent or
good results in 68.5% of cases. In 20% of the patients the results wer
e 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% o
f severe joint restriction. The overall recurrence rate was 13.9%. In
patients with atraumatic dislocation the recurrence rate was 12%, in p
atient with voluntary dislocation it was 50%, and in posttraumatic ins
tabilities the recurrence rate was 4.8%. The Rowe score showed 40% exc
ellent and good results. The poor results were among the patients with
redislocation, instabilities with subluxation, and secondary degenera
tive joint disease with concomitant pain and limitations in the range
of motion. In patients with voluntary instabilities the poor results w
ere 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 joi
nt disease developed. Considering the relatively high recurrence rate
and the amount of secondary degenerative joint disease after this proc
edure, we do not recommend this as a routine procedure for shoulder st
abilisation.
