Abstract
Introduction and Objectives: Distal humerus fractures in elderly people are associated with great comminuted fractures due to poor bone quality. The increased complexity caused by comminuted fractures is accompanied by difficulties in the fixation of osteosynthesis materials, thus facilitating the implant failure and altering the consolidation process. The objective is to analyze functional and radiological results and associated complications in patients 70 years of age or older, after surgical treatment of intra-articular distal humerus fractures. Materials and Methods: In total, 13 patients were evaluated between February 2012 and February 2015, treated with open reduction and internal fixation. Eight of these patients had C-type fractures and 6 A-type (Arbeitsgemeinschaft für Osteosynthesefragen [AO] classification). All patients were treated with double locking plate using a posterior approach with olecranon osteotomy. Radiological and functional assessments were made. Results: The average flexion range was 118°, though the loss of extension was 25°. Eighty-two percent of the patients had grade 1 arthrosis. We found 2 cases of pseudoarthrosis (one distal humerus and the other of olecranon) and 3 cases of neuropraxias (2 ulnar and 1 radial, which fully recovered). Three reinterventions were made (2 for material removal and 1 for reosteosintesis-vocabulario). The average Quick Disabilities of the Arm, Shoulder and hand Score was 19.87, and the Mayo Elbow Performance Score was 85. Discussion: Treatment with open reduction and internal fixation using two locking plates for A and C types of distal humerus in patients 70 years of age or older gave satisfactory functional results, according to patients’ demands, and do not significantly change the quality of life.
