Orthogonal Locking Compression Plate Fixation for Distal Humeral Intraarticular Fractures

ABSTRACT

PURPOSE: To investigate the surgical outcomes of orthogonal locking compression plate fixation for distal humeral intraarticular fractures. MATERIALS AND METHODS: This study included 18 patients presenting a distal humeral intraarticular fracture who were treated with orthogonal locking compression plate fixation. According to the AO/OTA classification, there were eight C2 and ten C3 fractures. We evaluated radiologic outcomes, clinical results with range of motion, operation-related complications, and functional score by Mayo elbow performance score (MEPS). RESULTS: The a verage u nion t ime was 3.5 months, and there was no c ase of r eduction l oss of a rticular f racture at t he last follow-up. Additional surgical procedures were needed in the three cases of C3 fractures. There was one case of heterotrophic ossification and one case of K-wire irritation. The average range of motion of elbow joint was 7° to 122°, and functional results were graded as 14 excellent, three good, and one fair by MEPS. CONCLUSION: Anatomical reduction and internal fixation with orthogonal locking compression plate could provide satisfactory surgical outcomes for the treatment of distal humeral intraarticular fracture.
