Clinical Outcome of Surgical Treatment of Distal Humerus Intercondylar Fractures Through the Transolecranon Approach Combined with Anterior Transposition of the Ulnar Nerve

ABSTRACT

PURPOSE: To analyze the clinical outcomes of surgical treatment of distal humerus intercondylar fractures through the transolecranon approach combined with anterior transposition of the ulnar nerve. MATERIALS AND METHODS: Eight patients who had distal humerus intercondylar fractures were included in this study and underwent operative treatment through the transolecranon approach for sufficient operative field with anterior transposition of the ulnar nerve and fixed with reconstruction plate. RESULTS: The results were evaluated using Riseborough and Radin rating criteria. Seven cases of eight cases were achieved good results with flexion contracture less than 30 degrees and forward flexion more than 115 degrees. However, one case was acheived poor result with 40 degrees of flexion contractue and 70 degrees of forward flexion. There were no the compressive ulnar neuropathy. CONCLUSION: We found the transolecranon approach and anterior transposition of the ulnar nerve a viable option for surgical treatment of the distal humerus intercondylar fractures
