Outcome of buttress plate fixation of coronoid process fracture via a modified anteromedial approach

Abstract

Fractures of Coronoid process of ulna are rare and difficult injury to treat with pain and instability to elbow. The aim is to study outcomes of buttress plate fixation of coronoid via modified anteromedial approach. We evaluated 15 patients from august 2017 to September 2019 with 9 (60%) of type II & 6(40%) of type III Regan-Morrey fractures. At final follow up all patient were have solid osseous union with mean elbow flexion & extension movement was 0 to129 degrees,4 patients have extension lag of 5 degrees,12 patients had full flexion of elbow while 3 patients have flexion upto 120 degrees. Mean supination movement was 79 degrees & mean pronation movement was 80 degrees. The mean MEPS score was 95 with 12 (80%) excellent and 3 (20%) good results. Coronoid factors can be treated with modified anteromedial approach and Buttress plating with excellent outcomes.
