Purpose:
Aim of this study was to evaluate the results after athroscopic transglenoidal stabilization in patients with anterior posttraumatic shoulder instability.
Methods:
30 patients with posttraumatic anterior shoulder instability were prospectively observed for a mean of 36 months (24-56) after an athroscopic stabilization has been performed. The operative technique was carried out as described by Morgan with use of transglenoidal sutures to repair the labrum.
Results:
All patients had a Bankart lesion and a Hill-Sachs defect. According to the criteria of Rowe, 24 patients (80%) had good or excellent results and 1 patient (3%) was graded as fair. 5 patients (17%) developed recurrent instability 6-24 months postoperatively so they had failed results. 83.4% had no or little limitation in sports activity. Sex, age or grade of activity had no influence on the result concerning stability. The mean preoperative dislocation rate was 8.6 for the failures and 5.9 for the stable results (p < 0.05).
Clinical Relevance:
The results of arthroscopic stabilization of the shoulder are inferior to the classical open repair. It should only be performed in patients with unidirectional, posttraumatic anterior shoulder instability without capsulaligamentous hyperlaxity or multiple resdislocations.
