Glenohumeral osteoarthrosis after the Eden-Hybbinette procedure.

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