Early complications of reverse total shoulder arthroplasty

Abstract

Background. The frequency of early complications after reverse shoulder arthroplasty remains high enough, and the overall complication rate is reported from 4.7% to 38%.
 Methods. We did 23 primary reverse shoulder arthroplasty and used clinical information after these operations in our study. As a comparative material, we used date from registers of foreign countries, as well as information from special literature.
 Results. Early complications were found in five cases (21.7%) in our study: two cases (8.7%) of a periprosthetic fracture; three patients (13.2%) had dislocation components. We studied these complications and formulated rules preventive measures.
 Conclusions. (1) The most common early complications after revers total shoulder arthroplasty were instability components, periprosthetic fracture. (2) These types of complications arise due to unbalanced soft tissues, inadequate selection of the size of the glenosphere, interposition of soft tissues, and inadequate term of loads on the operated limb. (3) The number of these complications can be reduced by observing preventive measures at all stages of treatment.
