Objective: study of the results of treatment of patients with the prevailing horizontal component of shoulder joint instability, operated with the use of the developed methods of surgical treatment aimed at reconstructing the rotator cuff and tendon of the long biceps head.

Materials. The author of the article studied the results of treatment of 62 patients with post-traumatic instability of the shoulder joint with the prevailing horizontal component from 2004 to 2018. In the study, patients were treated using the developed techniques and tactical approaches aimed at repairing damage to the rotator cuff and tendon of the long biceps head.

Results. When analyzing the results, a significant number of cases of friendly damage to the rotator cuff and tendon of the long biceps head were noted.

Conclusion. Developed minimally invasive interventions allow effective and low-impact restoration of stability and function in the shoulder joint.
