Abstract
The purpose of this study was to evaluate the relationships between the clinical manifestations of anterior glenohumeral instability and the physical and operative findings.
Method: We retrospectively reviewed 258 patients(212 males,146 females, aged 15-68, average 23yearsold)who underwent open surgery. The clinical manifestations of anterior glenohumeral instability were divided into 10 groups; (1) dislocations only, (2) shifting from dislocations to subluxations, (3) subluxations only, (4) shifting from subluxations to dislocations, (5) dead arm syndromes only. (6) shifting from dead arm syndromes to subluxations, (7) shifting from dead arm syndromes to dislocations, (8) from dislocations, and a combination of dislocations and subluxations, (9) from subluxations, and a combination of subluxations and dislocations, (10) others. These 10 patterns were compared with the age at the first dislocation, the times of the dislocating episode, generral joint laxities, shoulder joint laxity and the operative findings.
Results: There were no statistical difference between the patterns of anterior glenohumeral instability and the physical and operative findings. So we could not find any pathological differences between the dislocations, subluxations and dead arm syndromes.
