1Department of Sports Medicine, Beijing Jishuitan Hospital, Beijing 100035, China.
Objective:
To present the surgical technique and to evaluate the results of the modified arthroscopic Latarjet procedure.
Methods:
Arthroscopic Latarjet procedure has proven to be a reliable method of treatment for difficult anteroinferior instability of the shoulder joint. However, there is no anterior capsule reattachment and too much subscapularis damage for the classic procedure. From February 2013, we modified the classic procedure with reattachment of anterior joint capsule and muscle-tendon junction splitting of subscapularis. Coracoid graft position was evaluated using CT scanning.
Results:
From March 2012 to August 2014, 51 modified Latarjet procedures were successfully performed arthroscopically for patients with anterior shoulder instability. According to the CT scanning at the final follow up, the graft was flush with the glenoid in 94.1%, and medially placed in 5.9%. Vertical positioning was perfect in 96.0% (2 to 5 o'clock), too high in 2.0%, and too low in 2.0%. There were no cases of recurrent dislocation or subluxation.
Conclusion:
The modified arthroscopic Latarjet procedure has shown satisfactory results with good graft positioning. It is a minimal invasive and accurate approach, which combines the advantages of the open procedure.
