超音波診斷肩旋轉肌袖斷裂之回溯性分析

Ultrasonographic evaluation of patients suspected of rotator cuff tears

目的：肩旋轉肌袖部分斷裂經常很難診斷。因此，許多病人會被轉介進行進一步的超音波評估。本研究欲藉由肌肉骨骼超音波來評估被懷疑有肩旋轉肌袖斷裂之病人。方法：自2013年一月至2014年四月，共分析283位骨科醫師轉介的病人。吾人完整瀏覽電子病歷記錄，轉介目的，超音波影像及報告。結果：本研究包含171位女性及112位男性（平均年齡為55.98歲）。有102位病患（36.04%）於超音波檢查下被診斷為肩旋轉肌袖斷裂。被診斷肩旋轉肌袖斷裂者其中有90位（88.23%）為部分斷裂而12位（11.77%）為完全斷裂。最常斷裂的旋轉肌為棘上肌，而棘上肌也是最常鈣化的旋轉肌。棘上肌斷裂與棘上肌鈣化兩組均無性別上之統計學差異。結論：在使用超音波檢查疑似有肩旋轉肌袖斷裂的病人中，棘上肌斷裂與棘上肌鈣化為最常見之發現。

Objective: Partial thickness rotator cuff tears are often difficult to detect. Therefore, many patients are referred for ultrasonographic evaluation. The purpose of this study was to evaluate patients suspected of having rotator cuff tears by musculoskeletal ultrasonography. Methods: We analyzed 283 patients referred by orthopedic surgeons for musculoskeletal ultrasonography between January 2013 and April 2014. All electronic medical records, reasons of referral, images, and ultrasonographic reports were reviewed. Results: The study comprised 171 women and 112 men (mean age: 56.0 years). A total of 102 patients (36.0%) were confirmed to have rotator cuff tears by ultrasonography, including 90 cases of partial tear (88.2%) and 12 cases of complete tear (11.8%). The most frequent torn tendon was the supraspinatus, which was also the most frequent calcified rotator cuff tendon. There was no statistical gender differences in supraspinatus tendon tears or in calcified supraspinatus tendon. Conclusion: Among patients with suspected rotator cuff tears, supraspinatus tendon tear and calcification were most common ultrasonographic findings.
