Outcomes of Open Bankart Repair Plus Inferior Capsular Shift Compared with Latarjet Procedure in Contact Athletes with Recurrent Anterior Shoulder Instability

Background

Open Bankart repair plus inferior capsular shift (OBICS) and Latarjet procedure (LA) are considered appropriate treatment alternatives for high-performance athletes. The purpose of this study was to evaluate the functional outcomes and recurrence rate of each surgery. Our hypothesis: there were no differences between the two treatments.

Methods

A prospective cohort study was conducted with n=90 contact athletes divided into two groups of 45 patients. One group was treated with OBICS, and the other one with LA. The mean follow-up period was 25 (24-32) months for the OBICS group and 26 (24-31) months for the LA group. Primary functional outcomes of each group were assessed at baseline, six months, one year, and two years after surgery. The functional outcomes were also compared between the groups. The evaluation tools used were the Western Ontario Shoulder Instability score (WOSI) and the American Shoulder and Elbow Surgeons scale (ASES). In addition, recurrent instability and range of motion (ROM) were also evaluated.

Results

In each group, significant changes were found in the WOSI score and ASES scale from pre-op to postop. However, there were no significant differences between the functional outcomes of the groups at the final follow-up (P-values 0.73 and 0.19). Three dislocations and one subluxation (8.8%) were reported in the OBICS group, and three subluxations were reported in the LA group (6.6%), revealing no significant differences between the groups (P=0.37). Moreover, there were no significant differences between preoperative and postoperative ROM in each group or in terms of external rotation (ER) and ER in 90º abduction between the groups.

Conclusion

No differences were found between OBICS and LA surgery. Both procedures can be indicated according to the surgeon's preference to reduce recurrence rates in contact athletes with recurrent anterior shoulder instability.

Comparison of Open Bankart Repair versus Modified Bristow Operation for the Treatment of Traumatic Recurrent Anterior Dislocation and Capsular Laxity of the Shoulder

OBJECTIVE

The purpose of this study was to compare the results of open Bankart repair versus those of modified Bristow operation in patients with recurrent anterior dislocations of the shoulder, the last of which was caused by a minor trauma.

MATERIALS AND METHODS

This study included 38 patients (34 (89.5%) male and 4 (10.5%) female) who presented recurrent dislocation of the shoulders with capsular laxity and who underwent an open Bankart repair or a modified Bristow operation. The mean age of the patients was 29.6 years (range, 17-60 years). The mean follow-up period was 5.5 years (range, 35 months to 9 years). A total of 25 patients (65.8%) underwent an open Bankart repair, whereas 13 (34.2%) underwent a modified Bristow operation. The treatment results were assessed using the Rowe score for instability.

RESULTS

Of the 38 shoulders assessed, 24 (63.1%) were right shoulders and 14 (36.9%) were left shoulders. Furthermore, 26 (68.4%) were the dominant shoulders of the patients, and 12 (31.6%) were the non-dominant shoulders. The mean time from the first dislocation was 3.8 years (range, 10 months to 11 years). The age at which the first shoulder dislocation occurred was 20 years or younger in 7 cases (18.4%), 21-30 years in 22 cases (57.9%), 31-40 years in 6 cases (15.8%) and 41 or older in 3 cases (7.9%). The patients had experienced 4-10 recurrent dislocations in 15 cases (39.5%), 10-20 recurrent dislocations in 10 cases (26.3%) and 20 or more recurrent dislocations in 13 cases (34.2%). The mean Rowe score was 85.6 following open Bankart repair and 81.9 following modified Bristow. No significant difference was observed between these good and excellent Rowe scores following the open Bankart repair and the modified Bristow operation (p>0.05).

CONCLUSION

Proper patient selection for the open Bankart repair and the modified Bristow operation is crucial. When the proper patients have been selected for these procedures, both produce satisfactory results for the treatment of patients with capsular laxities.
