Open reduction and internal fixation in proximal humerus fractures by proximal humerus locking plate: A study of 60 cases

Abstract

Introduction: With respect to approach of proximal humerus fractures there has been a wide variation in optimum modality of treatment ranging from conservative treatment to total and reverse shoulder arthroplasty. We have evaluated the outcome of efficacy of proximal humerus locking plate in displaced proximal humerus fractures. Methods: A total of 60 patients with displaced proximal humerus fractures were included in the study after careful inclusion and exclusion criteria. All fractures were fixed with proximal humerus locking plate and patients were followed up at regular intervals. Final evaluation was done based on Constant and Murley shoulder scoring system. Results: According to Constant and Murley shoulder scoring system there were excellent results in 56.66% cases, good in 18.66%, fair in 13.33% and poor in 11.66% cases. There was no incidence of superficial or deep infection. There were 3 cases of AVN, 4 cases of varus collapse and 2 cases each of implant failure and non-union. Conclusion: Proximal humerus locking plate provides better fixation in proximal humerus fractures particularly in elderly and osteoporotic patients. Calcar screw placement is vital for prevention of varus collapse of fracture.
