Abstract

Introduction

This study presents the outcomes of fractures of the distal humerus treated by closed reduction and internal fixation with two screws in a crisscross orientation

Materials And Methods

Between 2005 and 2012, tweleve consecutive patients (2 man and 10 women) with transcondylar fractures of distal humerus (AO 13A2.3) were included in this study. The average age at the time of injury was 52 years (range, 24-82). All were closed injuries without nerve injury. The mechanism of the injuries was low energy fall or slip. Six patients had medical or other systemic diseases. Surgical technique: After a closed reduction of the fracture fragments, two guide wires were inserted in a crisscross orientation; one from the lower lateral edge of the capitellum to the medial cortex of the distal humerus, and the other from the lower medial edge of the trochlea to the lateral cortex of the distal humerus. After drilling, fully threaded cannulated screws (4.5 mm in diameter) were inserted along the each guide wire. Functional outcome was assessed with Mayo Elbow Performance scores.Results: The mean operation time was 55 minutes (range, 40-100 min.). The average follow-up duration was 26.8 months (range, 24-35 months) The mean Mayo Elbow Performance scores was 93.8 (range, 90-99). The elbow extension-flexion arc was 12o-125o. The mean pronation-supination angle was 74o-72o. Conclusion: a crisscross fixation with two cannluated screws provides satisfactory results that allows a nearly full range of elbow motion with minimal surgical morbidity.
