摘　　要：目的:对比分析肩袖全层撕裂中分层与非分层撕裂的MRI表现。方法:回顾性分析243例肩袖全层撕裂患者,根据撕裂类型及肌腱回缩距离分为病例1组、病例2组及对照组,记录撕裂口大小、肌腱回缩距离及冈上、冈下肌腹萎缩程度,根据数据分布类型,采用单因素方差分析或Kruscal-Wallis检验比较3组撕裂口大小、肌腱回缩距离及冈上、冈下肌腹萎缩程度。结果:243例肩袖全层撕裂患者中,分层撕裂145例(占59.7%)。病例2组滑囊侧肌腱回缩距离[(22.2±9.8)mm]与对照组[(29.7±12.0)mm]和病例1组[(29.0±12.5)mm]比较差异有统计学意义(P<0.01);病例2组关节侧肌腱回缩距离[(35.1±11.7)mm]与对照组[(29.7±12.0)mm]和病例1组[(29.0±12.5)mm]比较差异有统计学意义(P<0.01),3组间撕裂口大小、肌腹萎缩程度比较差异无统计学意义。结论:肩袖全层撕裂中分层撕裂较非层撕裂常见,不同分型中关节侧及滑囊侧肌腱回缩距离存在差异,肩袖修补术前,应充分认识分层撕裂的存在及类型,以确保损伤肩袖得以完整修复。Objective:To compare MR manifestations between delaminated rotator cuff tear and nondelaminated rotator cuff.Methods:Totally 243 cases with full-thickness rotator cuff tear were classified as group 1,group 2 and the control group based on the type of rotator cuff tear and the distance of retracted tendon.The tear length,the distance of retracted tendon,the degree of atrophy in musculus supraspinatus and musculus infraspinatus were recorded and compared by single factor ANOVA test or Kruscal-Wallis test according to the type of data distribution among three groups.Results:Delamination was present in 145 of 243 total tears(59.7%).There was statistical difference in the retraction distance of bursal layers between group 2(22.2±9.8)mm and control group(29.7±12.0)mm,between group 2(29.7±12.0)mm and group 1(29.0±12.5)mm,respectively(P<0.01).There was statistical difference in the retraction distance of bursal layers between group 2(35.1±11.7)mm and control group(29.7±12.0)mm,between group 2(35.1±11.7)mm and group 1(29.0±12.5)mm,respectively(P<0.01).There was no statistical difference in tear length and the degree of atrophy.Conclusion:The delaminated rotator cuff tear is more common than full-thickness rotator cuff tear.There is difference in the retraction distance between the articular side and the bursa side in different types.It is important to identify delaminated rotator cuff tear before operative repairs to make sure of the successful operation.
