[Object]
Traumatic anterior instability of the shoulder joint has been surgically treated by combined a modified Bristow method and a capsular shift method. The necessity of surgical intervention in the articular capsule is discussed based on the results of the follow-up.
[Subjects]
This study's subjects consisted of 55 patients with anterior dislocation or subluxation of the shoulder joint with a history of a frank trauma. They were aged 14 to 44 years at the time of surgery ( average 23.2 years).
[Method]
The 55 patients were operated on by a modified Bristow method combined with a capsular shift method. The results of the treatment were evaluated according to the evaluation criteria of the JOA scores. The pre-operative condition of the capsule was assessed by arthrography and a postradiography CT.
[Results]
There was no recurrence of a dislocation in any of the patients. The anterior instability of the shoulder joint improved satisfactorily, apprehension signs disappeared in all the patients except two. The mean JOA score markedly improved from 75.9 pre-treatment to 92.1 post-treatment.
[Conclusion]
The results obtained by the methods under discussion were very satisfactory, patients were only left with a slight limitation of external rotation. We suggest that there is aggressive intervention of the capsule in cases of anterior capsule injury, this treatment is indicated.
