The stabilizing role of the lateral ligament complex and the radial head were investigated in ten osteoligamentous elbow preparations. The annular ligament was the prime stabilizer of the lateral aspect of the elbow. Transection of the annular ligament caused maximal varus and external rotatory instability of 13.7 degrees and 32.8 degrees respectively, with an elbow flexion about 70 degrees. Isolated excision of the radial head caused slight varus and external rotatory instability of 4.8 degrees and 10.4 degrees respectively, with an elbow flexion about 40 degrees. The lateral collateral ligament had only a minor stabilizing function of the elbow. The stability of the elbow after excision of the radial head may be improved by proper preservation of the annular ligament.
在十具骨韧带化的肘关节标本上研究了外侧韧带复合体和桡骨头的稳定作用。环状韧带是肘关节外侧的主要稳定结构。切断环状韧带会导致肘关节在约70度屈曲时分别出现最大13.7度的内翻和32.8度的外旋不稳定。单独切除桡骨头会导致肘关节在约40度屈曲时分别出现轻微的4.8度内翻和10.4度外旋不稳定。外侧副韧带对肘关节的稳定作用较小。通过适当保留环状韧带，可改善桡骨头切除术后肘关节的稳定性。
