Introduction:

Anterior shoulder dislocation is an orthopedic injury with high risk of developing anterior glenohumeral instability. Its treatment is surgical and there are several techniques allowing reconstruction.

Objective:

To display the results of the modified Boytchev technique for the treatment of anterior shoulder instability.

Methods:

This is a retrospective study, case series type, with patients operated with modified Boytchev's technique. It redirects the conjoined biceps tendon and it is passed behind the subscapularis muscle to improve support on the anterior aspect of the glenohumeral joint.

Results:

Twenty two patients who had a minimum follow-up of 43 months were operated on. All were able to return to their work and sports activities. None had recurrence, mobility was complete. In one case, the osteosynthesis material loosened, but it was fixed without complications.

Conclusions:

This is a surgical technique that allows restoring the tension of the anterior soft tissues of the shoulder and satisfactorily correcting its instability; it does not expose the joint capsule or alter the length of the joint tendon, which results in less fibrosis. It is repeatable and safe, with a low rate of complications and allows returning to physical activities without compromising shoulder mobility.
