| 目的 采用MRI分析肩峰形态特点与肩袖撕裂（RCT）之间的关系。方法 回顾性分析37例RCT患者的临床与MRI资料，另选取19名健康志愿者作为对照组。肩峰形态分为4型：Ⅰ型（平坦型）、Ⅱ型（弧型）、Ⅲ型（钩型）、Ⅳ型（反弧型）。于MRI图像上测量与RCT发病机制相关的肩峰形态学特点的4个参数：肩肱间距（AHD）、肩峰指数（AI）、外侧肩峰角（LAA）和肩峰厚度。结果 Ⅱ型肩峰RCT的发生率最高，分别为病例组43.24%（16/37）、对照组57.89%（11/19）。2组间肩峰类型的分布差异无统计学意义（P>0.05），但AHD、AI、LAA和肩峰厚度测量值比较差异有统计学意义（P<0.05）。病例组中仅Ⅲ型肩峰各参数测量值与其他类型比较差异有统计学意义（P均<0.05）。结论 MRI可清晰显示肩袖形态，RCT患者的AHD和LAA值较小，AI和肩峰厚度值较大，Ⅲ型肩峰可能会增加RCT的风险。 |

| Objective To analyze the relationship between the morphological characteristics and rotator cuff tear (RCT) by MR. Methods The data of clinic and shoulder MRI of 37 patients with RCT (patients group) were analyzed retrospectively, and 19 healthy volunteers were collected in control group. The acromial shapes were classified into type Ⅰ (flat), type Ⅱ (curved), type Ⅲ (hooked) and type Ⅳ (convex). Additional measurements about pathogenesis of RCT including acromio-humeral distance (AHD), acromial index (AI), lateral acromial angle (LAA) and acromial thickness were performed for further assessment. Results Type Ⅱ was the most commonly encountered acromial shape in patients group (16/37, 43.24%) and control group (11/19, 57.89%). There was no statistically significant difference in the incidence of each acromial shape between two groups (P>0.05). However, the AHD, AI, LAA and acromial thickness showed statistically significant difference between the patients group and control group (all P<0.05). The type Ⅲ acromion was significantly different from the other types in patients group (P<0.05). Conclusion MRI can clearly display RCT. The AHD and LAA are smaller, the AI and acromial thickness are bigger in RCT patients. Type Ⅲ acromion may increase risks for RCT. |
