Abstract
Posterolateral rotatory instability (PLRI) is the most commonly encountered pattern of elbow instability. It is the result of disruption of the lateral collateral ligament complex leading to a posterolateral rotatory subluxation of the ulna and radial head. A number of examination maneuvers have been described to assist in clinical identification of PLRI. Despite this, some inconsistency in the description of these techniques remains in the orthopaedic literature. This Technical Note details the mechanism of injury and patient presentation, and emphasizes the primacy of the posterolateral rotatory drawer test in the assessment of PLRI while providing video instruction on how it should be performed.
摘要
后外侧旋转不稳定（PLRI）是最常见的肘关节不稳定类型。它是外侧副韧带复合体断裂的结果，导致尺骨和桡骨头后外侧旋转半脱位。已经描述了多种检查手法来辅助PLRI的临床诊断。尽管如此，骨科文献中对这些技术的描述仍存在一些不一致之处。本技术说明详细介绍了损伤机制和患者表现，并强调了后外侧旋转抽屉试验在评估PLRI中的首要地位，同时提供了该试验应如何进行的视频指导。
