The relationship between the number of shoulder dislocations and the depth and percent of head involvement of the Hill-Sachs lesions was investigated in this study. Thirty patients with recurrent anterior dislocation of the shoulder were divided into three groups according to the numbers of dislocations they had presented: Group 1: 1 to 5 dislocations ; Group 2: 6 to 20; Group 3: over 20. The mean percentage of head involvement was 11.9% in the first group, 25.4% in the second group and 26% in the third group of patients with Hill-Sachs lesions. The average depth of the Hill-Sachs lesions was 4.14 mm in the first group, 5.13 mm in the second group and 4.38 mm in the third group. Based on these findings, it appears that there is a correlation between the number of dislocations and the extent and depth of the Hill-Sachs lesions. Surgical treatment should therefore be performed as early as possible in patients with recurrent anterior dislocation of the shoulder, in order to prevent progression of the Hill-Sachs lesion which can become by itself a cause of instability.
本研究调查了肩关节脱位次数与Hill-Sachs损伤的肱骨头受累深度及百分比之间的关系。30例复发性肩关节前脱位患者根据其脱位次数分为三组：第1组：1至5次脱位；第2组：6至20次；第3组：超过20次。患有Hill-Sachs损伤的患者中，第1组肱骨头受累的平均百分比为11.9%，第2组为25.4%，第3组为26%。Hill-Sachs损伤的平均深度在第1组为4.14mm，第2组为5.13mm，第3组为4.38mm。基于这些发现，脱位次数与Hill-Sachs损伤的程度和深度之间似乎存在相关性。因此，对于复发性肩关节前脱位患者，应尽早进行手术治疗，以防止Hill-Sachs损伤进展，其本身可能成为不稳定的原因。
