Features of reverse arthroplasty of the shoulder joint in orthopedic pathology of the glenoid (literature review)
Abstract
The reverse shoulder arthroplasty in the conditions of the modified anatomy of the glenoid is complex and often excludes the possibility of using the standard tactics of installing the glenoid component. There are no identical glenoids, each articular cavity of the scapula differs in height, width, angle of inclination, density of bone tissue, absence or presence of various defects of bone tissue. Given the variety of options for changing the structure and quality of the glenoid bone tissue in injuries and diseases of the shoulder joint, each case of endoprosthetics should be considered individually. In order to perform an adequate metaglen installation, these parameters must be normalized or standardized. The purpose of this work is to review the domestic and foreign literature devoted to the features of reversible shoulder joint replacement during deformation of the articular cavity of the scapula. Based on the analysis of literature data, the percentage of complications associated with unsatisfactory treatment results due to the instability of the glenosphere is quite large, which indicates the lack of elaboration of this topic and its relevance for practical traumatology and orthopedics. The paper considers eccentric non-standard methods of rimming the articular cavity of the scapula, methods of its bone grafting, the use of metaglens made taking into account the deformation of the glenoid, as well as indications for the use of technology for the individual manufacture of scapular components. The study and analysis of indications for the use of various types of techniques for solution glenoid deformities made it possible to systematize and differentially approach the issue of preoperative planning and choosing the correct, right treatment tactics in complex cases of reversible shoulder joint replacement.
