Abstract

Abstract:

BACKGROUND: Distal humerus fracture is often comminuted, and is difficult to receive reduction and fixation due to its special anatomical structure. Choosing which surgical approach is still a controversy.

OBJECTIVE: To compare and analyze the curative efficacy of the perpendicular double-locking plating system for the internal fixation of type C distal humerus fractures through two kinds of postcubital approaches.

METHODS: Thirty-two cases of type C distal humerus fractures were enrolled and divided into groups A (osteotomy of olecranon approach) and B (tricep anconeus flap approach). There was no significant difference in the baseline data between two groups. The operation time, intraoperative blood loss, hospital stay, healing time, postoperative follow-up and complications were recorded and analyzed. The patients were followed up at 2 weeks, 1, 3, 6, 12, and 18 months. The healing time and complications were recorded according to radiographs and physical examinations. The Mayo Elbow Performance Score was used to determine the elbow function at 1 year postoperatively.

RESULTS AND CONCLUSION: (1) The group A had a longer operation time and more intraoperative blood loss than those in the group B (P < 0.05), but showed a better elbow flexion and extension degrees, and higher Mayo Elbow Performance Score at 1 year postoperatively (P < 0.05). (2) There was no significant difference in the healing time between two groups (P > 0.05). (3) These results suggest that the articular surface of the distal humerus fracture is displayed well through two approaches, and the perpendicular double-locking plating system for the internal fixation of type C distal humerus fractures is rational. Noticeably, the tricep anconeus flap approach dose little damage to the muscle, while the osteotomy of olecranon approach obtains better elbow function and less complications.
