Diagnostics and methods of solving the reduction of bone mineral density and deformities of the articular cavity of the scapula during reverse shoulder arthroplasty

Background . Reverse arthroplasty is an effective method of treating severe injuries and diseases the shoulder joint. In cases osteoporosis, defects deformities glenoid, there are risks incorrect installation instability components endoprosthesis. literature data, problem osteoporosis in endoprosthetics joint methods its solution rather poorly reflected, which was reason for this study. The aim : to develop algorithms diagnosing state bone tissue articular cavity scapula solving deviations during reverse arthroplasty. Materials Forty-eight patients who underwent reversible replacement were examined Department Adult Orthopedics N.N. Priorov National Medical Research Center Traumatology Orthopedics. A standard preoperative examination developed department performed, as well additional calculations density Hounsfield units according X-ray densitometry performed. parameters glenoid (in HU) compared with data densitometry. Results According results densitometry, divided into groups. direct dependence indicators revealed. Algorithms treatment preparation deficiency have been developed. Conclusions studied groups, 100 % below 139 HU diagnosed or osteopenia, more than 257 had normal mineral density.
