UNASSIGNED: To investigate the prevalence and location of rotator cuff tears (RCTs), including PASTA lesions, in shoulders with recurrent anterior instability.
UNASSIGNED: Case series; Level of evidence, 4.
UNASSIGNED: A total of 842 shoulders in 801 patients with recurrent anterior instability (647 men, 154 women; mean age, 24 years; age range, 13-40 years) who underwent arthroscopic surgery at the age of 40 years or younger were enrolled. During surgery, the thickness and the sites of RCTs as well as patient factors associated with RCTs were examined.
UNASSIGNED: RCTs were found in 57 shoulders (7%) in 56 patients. There were 4 shoulders with full-thickness RCTs and 54 shoulders with PASTA lesions. All lesions but 1 involved the anterior border of the supraspinatus (SSP). Participation in high-level athletics and older age at injury were associated with RCTs.
UNASSIGNED: The incidence of RCTs was 7% in shoulders with recurrent anterior instability at age 40 years or younger. Most RCTs were PASTA lesions that involved the anterior border of the SSP.
■为了调查肩袖撕裂(RCT)的患病率和位置,包括PASTA病变,在肩关节反复出现的前不稳定。
■案例系列;证据级别,4.
■801例复发性前不稳患者中共有842个肩膀(647名男性,154名妇女;平均年龄,24岁;年龄范围,13-40岁)在40岁以下接受关节镜手术的患者被纳入。手术期间,检查了RCT的厚度和部位以及与RCT相关的患者因素.
■在56例患者的57名肩部发现了RCT(7%)。有4个肩部的全厚度RCT和54个肩部的PASTA病变。所有病变均累及冈上肌(SSP)的前边界。参加高水平运动和受伤时年龄较大与RCT有关。
■在40岁或更年轻时复发性前不稳定的肩部中,RCT的发生率为7%。大多数RCT是PASTA病变,涉及SSP的前缘。
