The effect of the articular capsule on elbow stability is not well documented. Releasing the capsule might modify results of elbow arthrolysis, especially if it would lead to postoperative instability. The goal of the present study was to address the question in a cadaveric study.
Ten fresh cadaver elbows were studied. Anterior and posterior capsulectomy was performed. Lateral and medial collateral ligaments were preserved. Initially, the same operator tested the elbow joints manually in flexion-extension, valgus-varus, and pronosupination. The same joints were then tested with an experimental machine.
Under these experimental conditions, no articular laxity was noticed in the coronal or sagittal planes after anterior and posterior isolated capsular release when the elbow joint was exposed to axial rotation, compression, or traction forces. Elbow laxity was observed only when lateral or medial ligaments were released.
Anterior and posterior capsulectomy during elbow joint arthrolysis does not produce joint instability when the lateral and medial ligaments are preserved.
关节囊对肘关节稳定性的影响尚无充分文献记载。松解关节囊可能会改变肘关节松解术的结果，尤其是如果这会导致术后不稳定。本研究的目的是在尸体研究中解决这个问题。
对10个新鲜尸体肘关节进行研究。进行了前后关节囊切除术。保留了内外侧副韧带。最初，由同一名操作者手动测试肘关节在屈伸、内外翻和旋前旋后时的情况。然后用实验机器对相同的关节进行测试。
在这些实验条件下，当肘关节受到轴向旋转、压缩或牵引力时，单独进行前后关节囊松解后，在冠状面或矢状面未观察到关节松弛。仅在松解外侧或内侧韧带时观察到肘关节松弛。
当保留内外侧韧带时，肘关节松解术中的前后关节囊切除术不会导致关节不稳定。
