摘要

研究目的本研究旨在评估三种关节镜技术在术中评估后外侧旋转不稳定(PLRI)的敏感性:研究使用了六具新鲜冷冻尸体上肢。三种关节镜测试分别为改良尺桡关节穿刺测试、环形穿刺测试和近端桡腓关节器械检查。依次进行软组织切片,以形成四个阶段的不稳定:基线、横断侧副韧带复合体的前半部分(即桡侧副韧带)、横断LCL复合体的后半部分(即尺侧副韧带),最后松解共同伸肌起源。每项测试都在肘关节屈曲90度中立旋转和伸展45度完全上举的状态下重复进行:结果:每项测试都能正确识别外侧尺侧副韧带的缺失。改良尺桡侧副韧带通过试验和环形通过试验对桡侧副韧带缺失最敏感。肘部位置并不影响测试的灵敏度:结论:无论肘部位置如何,每种测试都能高灵敏度地识别桡侧副韧带损伤。尺肱骨和环韧带通过测试对桡侧副韧带断裂更为敏感。

Arthroscopic evaluation for posterolateral rotatory instability of the elbow.

Objective: The purpose of this study was to evaluate the sensitivity of three arthroscopic techniques for intraoperative assessment of posterolateral rotatory instability (PLRI).

Methods: The study was performed using six fresh frozen cadaveric upper extremities. The three arthroscopic tests were the modified ulnohumeral drive through test, the annular drive through test, and proximal radioulnar joint instrumentation. Sequential soft tissue sectioning was performed to create four stages of instability: baseline, transection of the anterior half of the lateral collateral ligament complex (i.e., the radial collateral ligament), transection of the posterior half of the LCL complex (i.e., the lateral ulnar collateral ligament), and finally the release of the common extensor origin. Each test was repeated with the elbow at 90-degrees flexion in neutral rotation and at 45-degrees extension in full supination.

Results: Each test appropriately identified loss of the lateral ulnar collateral ligament. The modified ulnohumeral drive through test and the annular drive through test were most sensitive for loss of the radial collateral ligament. Elbow position did not affect test sensitivity.

Conclusions: Each of the tests identified PLRI with high sensitivity, regardless of elbow position. The ulnohumeral and annular ligament drive through tests were more sensitive for radial collateral ligament disruption.
