In this study we investigated the pathologies of an initial anterior dislocation of the shoulder by arthroscopy, and reported of the results of an arthroscopic Bankart repair (Caspari's method).
Sixteen cases of intial traumatic anterior dislocation of the shoulder were treated. The intra-articulate pathologies of all the cases were investigated, and the Bankart repair was performed using Caspari's method.
Arthroscopic examination showed that the AIGHL-labral complex(AIGHLC) was detached from the glenoid rim in all the cases. Twelve (75%) of the patients had inferior displacements of the AIGHLC and 4 (25%) patients had medial displacements. The average Rowe score was 94 points (80-100), and there were no recurrences.
In conclusion, detachment of the anterior labrum from the glenoid rim, and inferior and medial displacements of the AIGHLC are thought to be the main lesions of anterior instability. Caspari's method is effective for preventing recurrence because it repairs the Bankart lesion and shifts the AIGHLC.
