This preliminary prospective study was conducted to determine whether immobilization with the arm in external rotation would decrease the rate of recurrence after initial traumatic anterior dislocation of the shoulder. Forty patients with initial shoulder dislocations were assigned to (1) conventional immobilization in internal rotation (IR group, n = 20) or (2) a new method of immobilization in external rotation (ER group, n = 20). The recurrence rate was 30% in the IR group and 0% in the ER group at a mean 15.5 months. The difference in recurrence rate was even greater among those who were aged less than 30 years (45% in the IR group and 0% in the ER group). Immobilization with the arm in external rotation is effective in reducing the rate of recurrence after initial dislocation of the shoulder.
本前瞻性初步研究旨在确定肩部初始创伤性前脱位后，外旋位固定手臂是否会降低复发率。40例初次肩关节脱位患者被分为两组：（1）传统内旋位固定（IR组，n = 20）；（2）新的外旋位固定方法（ER组，n = 20）。平均随访15.5个月时，IR组复发率为30%，ER组为0%。年龄小于30岁者的复发率差异更大（IR组为45%，ER组为0%）。肩部初次脱位后，外旋位固定手臂对降低复发率有效。
