The lateral ligament complex is the primary constraint to posterolateral rotatory laxity of the elbow, and if it is disrupted during surgery, posterolateral instability may ensue. The Wrightington approach to the head of the radius involves osteotomising the ulnar insertion of this ligament, rather than incising through it as in the classic posterolateral (Kocher) approach. In this biomechanical study of 17 human cadaver elbows, we demonstrate that the surgical approach to the head can influence posterolateral laxity, with the Wrightington approach producing less posterolateral rotatory laxity than the posterolateral approach.
外侧韧带复合体是肘关节后外侧旋转松弛的主要限制因素，如果在手术中受到破坏，可能会导致后外侧不稳定。桡骨头的Wrightington入路涉及将该韧带的尺侧附着点进行截骨，而不是像经典的后外侧（Kocher）入路那样切开它。在这项对17个尸体人肘关节的生物力学研究中，我们证明了桡骨头的手术入路会影响后外侧松弛度，Wrightington入路产生的后外侧旋转松弛度比后外侧入路小。
