Reverse total shoulder arthroplasty for type I fracture sequelae after internal fixation of proximal humerus fractures

摘要

Abstract Introduction Complications after internal fixation of proximal humerus fracture are common and may require surgical revision. Reverse total shoulder arthroplasty (RTSA) is frequently performed in such cases. The aim of the present study was to evaluate the functional results and complications after RTSA for the treatment of type I fracture sequelae after internal fixation of proximal humerus fractures. Materials and methods 26 patients (18 female, 8 male) underwent surgical revision of type I fracture sequelae of the proximal humerus after locking plate ( n ?=?22) or intramedullary nail ( n ?=?4) fixation. The mean age of the patients at the time of the revision was 75?years (range 65–89). After a mean follow-up of 36?months (range 18-58), clinical examination was performed and the age- and gender-related Constant–Murley Score (CMS) and the Oxford Shoulder Score (OSS) were obtained from all patients and compared to the pre-revision values. Results The mean age- and gender-related CMS of the affected shoulder increased from 44% (range 17–65) to 73% (range 44–97). This difference was statistically significant ( p ? p ? Conclusion Satisfying results can be obtained with RTSA as a salvage procedure for type I fracture sequelae after previous internal fixation of proximal humerus fractures.
