The purpose of this study was to use MR imaging to evaluate the prevalence and extent of rotator cuff tears in paraplegic patients, who are at increased risk for impingement caused by overuse.
Sixty-four MR examinations of the shoulder were evaluated for partial or full-thickness rotator cuff tears and for single or multiple rotator cuff tendon tears. Thirty-seven MR studies were from paraplegic subjects (26 symptomatic, 11 asymptomatic), and 27 MR studies were from able-bodied subjects (17 symptomatic, 10 asymptomatic).
Among subjects who were symptomatic and paraplegic, 73% of shoulders imaged showed evidence of rotator cuff tear on MR images compared with 59% of shoulders in able-bodied symptomatic subjects. Of all subjects with paraplegia, 57% of shoulders imaged showed rotator cuff tears. Among all paraplegic subjects, prevalence and severity of tears correlated positively with age and duration of spinal cord injury. Tears that involved the posterior portion of the rotator cuff were revealed on MR images in 74% of the paraplegic subjects compared with 50% of the able-bodied subjects.
MR imaging revealed a high percentage and degree of severity of rotator cuff tears in individuals with paraplegia and thus proved useful in evaluating shoulders in these patients.
本研究旨在利用磁共振成像（MR）评估截瘫患者肩袖撕裂的患病率和范围，这些患者因过度使用而发生撞击的风险增加。
对64例肩部MR检查进行评估，以确定肩袖部分或全层撕裂以及单处或多处肩袖肌腱撕裂情况。37例MR研究来自截瘫患者（26例有症状，11例无症状），27例MR研究来自健全受试者（17例有症状，10例无症状）。
在有症状的截瘫受试者中，73%的肩部MR图像显示有肩袖撕裂迹象，而健全有症状受试者中这一比例为59%。在所有截瘫受试者中，57%的肩部MR图像显示有肩袖撕裂。在所有截瘫受试者中，撕裂的患病率和严重程度与年龄及脊髓损伤持续时间呈正相关。MR图像显示，74%的截瘫受试者肩袖撕裂累及后部，而健全受试者中这一比例为50%。
MR成像显示截瘫患者肩袖撕裂的比例和严重程度较高，因此在评估这些患者的肩部情况时很有用。
