Glenohumeral osteoarthrosis after the Eden-Hybbinette procedure

Thirty-six patients (36 shoulders) who underwent the Eden-Hybbinette proced ure for recurrent anterior dislocation of the shoulder with an average foll owup of 15 years were evaluated, Evaluation consisted of radiographic asses sment in a true anteroposterior view and an axillary lateral view of both s houlders, physical examination, and a questionnaire. Mild glenohumeral oste oarthrosis was present in 1/3 of the patients, and moderate and severe oste oarthrosis was evident in 1/2. There were no signs of osteoarthrosis in fou r shoulders. Function, as assessed by the Rowe score as modified by Young a nd Rockwood, was excellent or good in 27 shoulders and fair or poor in nine shoulders. The extent of osteoarthrosis was related to restriction of exte rnal rotation, length of followup, and function.
