The records of all Olmsted County, Minnesota residents treated for an initial traumatic anterior shoulder dislocation during a ten-year period were reviewed to study the incidence and natural history of this condition. One hundred twenty-four patients had been treated during the study period, and in 116 patients (93.5%) complete follow-up evaluation was available. The overall adjusted incidence of initial traumatic shoulder dislocations was 8.2/100,000 person-years; of all traumatic shoulder dislocations, the rate was at least 11.2/100,000 person-years. Incidence rates were significantly greater for men than for women. There was no urban versus rural difference in incidence or recurrence rates. The authors concluded that shoulder dislocation occurs most frequently in younger male patients and occurs with similar frequency in urban and rural settings. Except for age-related differences in recurrence rates no significant referral bias was found among patients treated at a tertiary care facility as compared with patients from the local community.
回顾了明尼苏达州奥尔姆斯特德县在十年期间接受初次创伤性前肩关节脱位治疗的所有居民记录，以研究这种疾病的发病率和自然史。在研究期间有124名患者接受了治疗，其中116名患者（93.5%）有完整的随访评估。初次创伤性肩关节脱位的总体校正发病率为8.2/10万人口年；在所有创伤性肩关节脱位中，该比率至少为11.2/10万人口年。男性的发病率明显高于女性。发病率和复发率在城市和农村之间没有差异。作者得出结论，肩关节脱位最常发生在年轻男性患者中，在城市和农村环境中的发生频率相似。除了复发率的年龄相关差异外，与当地社区患者相比，在三级医疗机构接受治疗的患者中未发现明显的转诊偏倚。
