Outcome of fixation of distal humerus fracture via paratricipital approach – A prospective study

Abstract

Background: Fractures of the distal humerus continue to challenge surgeons due to their complex nature and the multiple options of fixation. The olecranon osteotomy approach is considered the gold standard, especially in those fractures with an intra-articular comminution, but is associated with complications. In selected cases, utilizing the triceps-on or paratricipital approach should allow adequate fixation while decreasing the incidence of complications. Methods: Patients with distal humerus fractures were treated with open reduction and internal fixation via the paratricipital approach. All patients were evaluated based on their preoperative and intraoperative parameters. Postoperative rehabilitation was implemented and the functional outcome was assessed based on the range of motion and Mayo Elbow Performance Score. Results: The current study encompassed thirty patients with a mean age of 47.5 years. AO/OTA C1 type fracture was encountered in 13 patients. The mean operative time was around 90 min. The mean elbow flexion at 2 months was 127.5°. Union was achieved in all patients, and one patient had surgical site infection. Conclusion: Metaphyseal and simple inter-articular fractures may be adequately visualized and managed with the above approach. Early rehabilitation allows faster return to normal function.
