ABSTRACT

Objective To study the clinical efficacy and safety of Bryan-Morrey approach combined with anatomic locking plate fixation for the treatment of type C fractures of distal humerus.Methods Performed a prospective study from from Mar.2011 to Aug.2014.Thirty-three cases of distal humerus fracture were included in our study,and the mean age was (37.3 ±4.1) years old.The fracture type of distal humerus was 13-C according to Mayo classification.All the fractures treated with a Bryan-Morrey approach and anatomic locking plates.In the follow-up,Mayo scores of elbow,measurement of range of motion,elbow flexion and extension muscle strength were recorded and analysed.Results In this study,there were no serious complications,such as nonunion,rupture of triceps tendon and the infection,except partial sensory function injury of ulnar nerve in 5 cases.At the last time of the follow-up,elbow flexion muscle strength and extension muscle strength did not significantly decreased significantly compared with strength of the normal side.The mean flexion of the injured side was (134.5 ± 10.1) degrees,and the mean extension was (-1 1.5 ± 8.1) degrees.According to Mayo elbow performance score,the average scores of elbow was (86.2 ± 7.8),84％ of the patients got excellent or very excellent function results.Conclusion The Bryan-Morrey approach combined with anatomic locking plate fixation is a good choice for the treatment of distal humerus fractures of AO C type.
