Purpose. To develop an algorithm of actions for shoulder arthroplasty with reverse implants in conditions of bone mass deficiency of the articular cavity of the scapula. Material and methods. In the conditions of the 8th department of the N. N. Priorov National Research Medical Center of the Ministry of Health of the Russian Federation, reverse shoulder arthroplasty was performed in patients with bone mass deficiency of the articular cavity of the scapula, who were replaced with both marginal and extensive bone defects of the glenoid. Results. On the basis of the conducted research, a consistent surgical tactic was developed to compensate for the lack of bone tissue of the scapula and to implant the components of a reversible shoulder endoprosthesis. Conclusion. The developed tactics of actions for defects of the articular cavity of the scapula allows for reverse shoulder arthroplasty in these complex clinical cases, taking into account the disturbed anatomy of the shoulder joint.
