目的肩胛上切迹（SSN）的侧侧差异和骨化的上级肩胛横韧带的临床特征尚不清楚。因此，形态不对称的SSN进行了调查，并与骨化的上级肩胛横韧带的相关因素进行了analysed.MethodsTwo和76计算机断层扫描图像进行了回顾性分析，其中包括那些亚洲患者（平均年龄，62.1 ± 19.1岁，男性，197）的肩胛骨高能量损伤或呼吸系统疾病。根据Rengachary的分类，使用重建的三维计算机断层扫描将SSN的变化分为六种类型。组与VI型SSN（完全骨化的上级肩胛横韧带）在至少一个肩胛骨与其他组的年龄，性别和慢性comorbidity.ResultsAmong 276例患者，95（34.4%）有不对称的SSN和15（5.4%）有VI型SSN。两组之间在年龄、性别或合并症方面没有显著差异。然而，在比较年龄组时，VI型SSN的患病率在年龄> 70岁的患者中高于年龄< 70岁的患者。15例患者VI型SSN，这是单侧的10 patients.ConclusionAsymmetric SSN中观察到的亚洲患者的三分之一。个体之间和个体内部的SSN存在差异。在肩胛上神经麻痹的情况下，与健康侧相比，SSN形态的差异应予以考虑。证据等级III。
PurposeThe side-to-side differences within an individual’s suprascapular notch (SSN) and the clinical characteristics of an ossified superior transverse scapular ligament are unclear. Therefore, the morphological asymmetry of the SSN was investigated, and the factors associated with the ossification of the superior transverse scapular ligament were analyzed.MethodsTwo hundred and seventy-six computed tomography images were retrospectively analyzed, which included those of both scapulae of Asian patients (mean age, 62.1 ± 19.1 years; males, 197) with high-energy injuries or respiratory diseases. Variations in the SSN were classified into six types based on Rengachary’s classification using reconstructed three-dimensional computed tomography. The group with a type VI SSN (completely ossified superior transverse scapular ligament) in at least one scapula was compared with the other group for age, sex, and chronic comorbidities.ResultsAmong 276 patients, 95 (34.4%) had asymmetric SSNs and 15 (5.4%) had type VI SSNs. There were no significant differences in age, sex, or comorbidities between both the groups. However, on comparing age groups, the prevalence of type VI SSN was higher in patients aged > 70 years than in those aged < 70 years. Fifteen patients had type VI SSNs, which were unilateral in 10 patients.ConclusionAsymmetric SSNs were observed in a third of the Asian patients. There were variations in SSNs between individuals and also within an individual. In the cases with suprascapular nerve paralysis, the difference in SSN morphology compared to a healthy side should be considered.Level of evidenceIII.
