通过流行病学调查和病理解剖观察，提示尺神经滑脱可能与组织结构发育缺陷有关，如肱骨内上髁较小，肘管三角韧带及尺神经系膜松弛等。男女之间尺神经滑脱发生率有显著性差异。肘部尺神经滑脱并非少见，鉴于尺神经滑脱者发生肘部尺神经损害的危险性较一般人群高，一旦尺神经损害其所支配的已挛缩的手内在肌很难恢复，尺神经滑脱者是值得人们注意的肘部尺神经损害的易感人群。因尺神经滑脱者除上述结构缺陷外，更重要的是尺神经滑脱过程为重复累积性损伤，故尺神经前移以免尺神经在肱骨内上髁反复摩擦损伤为首选的治疗方法。
Through epidemiological investigation and pathological observation, ulnar nerve spondylolisthesis may be related to the development of tissue defects, such as the smaller humeral medial condyle, elbow triangle ligament and ulnar mesangial relaxation. There was a significant difference in the incidence of ulnar nerve slippage between men and women. Elbow ulnar nerve slippage is not uncommon, in view of ulnar nerve spondylolisthesis occurred in elbow ulnar nerve damage risk than the general population, once the ulnar nerve damage at its disposal contracture of the hand internal muscle is difficult to recover, ulnar nerve spondylolisthesis are It is noteworthy that the ulnar ulnar nerve damage is predisposed to the crowd. In addition to the ulnar nerve slippage in addition to the above structural defects, more importantly, ulnar nerve spondylolisthesis is a cumulative cumulative injury, so the ulnar nerve in order to avoid the ulnar nerve in the humerus repeated injury of the epicondyle as the preferred treatment.
