To investigate the effect of anteromedial coronoid facet fracture and lateral collateral ligament complex (LCLC) injury on the posteromedial rotational stability of the elbow joint.
The double elbows were obtained from 4 fresh adult male cadaveric specimens. Complete elbow joint (group A, =8), simple LCLC injury (group B, =4), simple anteromedial coronoid facet fracture (group C, =4), and LCLC injury combined with anteromedial coronoid facet fracture (group D, =8). The torque value was calculated according to the load-displacement curve.
There was no complete dislocation of the elbow during the experiment. The torque values of groups A, B, C, and D were (10.286±0.166), (5.775±0.124), (6.566±0.139), and (3.004±0.063) N·m respectively, showing significant differences between groups ( <0.05).
Simple LCLC injury, simple anteromedial coronoid facet fracture, and combined both injury will affect the posteromedial rotational stability of the elbow.
探讨冠状突前内侧小关节面骨折及外侧副韧带复合体（LCLC）损伤对肘关节后内侧旋转稳定性的影响。
从4具新鲜成年男性尸体标本上获取双侧肘关节。完整肘关节（A组，n = 8）、单纯LCLC损伤（B组，n = 4）、单纯冠状突前内侧小关节面骨折（C组，n = 4）以及LCLC损伤合并冠状突前内侧小关节面骨折（D组，n = 8）。根据载荷 - 位移曲线计算扭矩值。
实验过程中肘关节均未发生完全脱位。A、B、C、D组的扭矩值分别为（10.286±0.166）、（5.775±0.124）、（6.566±0.139）和（3.004±0.063）N·m，组间差异有统计学意义（P<0.05）。
单纯LCLC损伤、单纯冠状突前内侧小关节面骨折以及两者合并损伤均会影响肘关节的后内侧旋转稳定性。
