ABSTRACT

Objective:

To observe the changes in acromiaohumeral distance(AHD) in patients undergoing the modified arthroscopic double-button Latarjet procedure for recurrent anterior shoulder dislocation complicated with glenoid bone defect.

Methods:

A retrospective study was performed of the 52 patients who had undergone the modified arthroscopic double-button Latarjet procedure from October 2014 to October 2016 at Department of Sports Medicine, The First Affiliated Hospital to Shenzhen University for recurrent anterior shoulder dislocation complicated with glenoid bone defect. They were 33 males and 19 females, having 30 left and 22 right shoulders affected. Their ages ranged from 19 to 45 years(mean, 29.6 years). Their glenoid bone defects ranged from 17% to 30%(mean, 23.4%). CT scans were performed on the surgery side to observe the healing and reshaping of the bone grafts and to measure the AHDs of healthy shoulder, immediately, 6, 18 and 36 months after operation. Their American Shoulder and Elbow Surgeons(ASES), Rowe and Walch-Duplay scores were recorded before operation and at the final follow-up for comparison.

Results:

The follow-up time for this series ranged from 37 to 44 months (mean, 40.6 months). The AHDs at immediate postoperation(9.6 mm ± 0.7 mm), 6 months postoperation(8.6 mm ± 0.9 mm), 18 months postoperation (8.0 cm ± 0.8 cm) and 36 months postoperation(7.9 cm ± 0.8 cm) were significantly wider than the healthy side value (7.8 mm ± 0.8 mm)( P<0.05). The ASES, Rowe and Walch-Duplay scores at the final follow-up (93.9±3.2, 94.5±2.7 and 95.7±3.6) were significantly improved than the preoperative values (67.3±9.1, 40.1±4.2 and 63.5±9.0) ( P<0.05). The final follow-ups observed no symptoms or signs of chronic shoulder pain, rotator cuff injury or acromion impingement.

Conclusion:

As the AHD becomes wider rather than narrower after arthroscopic double-button Latarjet procedure for recurrent anterior shoulder dislocation complicated with glenoid bone defect, no subsequent rotator cuff injury may happen due to the uplift of the humeral head after the modified arthroscopic double-button Latarjet procedure.
