中文摘要 | 背景 旋轉肌腱撕裂通常由於肩部夾擊所形成,並且需要手術的治 療。本篇研究即是來確認哪些旋轉肌腱夾擊症之磁振影像的表現,是與全層旋 轉肌腱撕裂有關聯。 方法 研究對象為68位有旋轉肌腱夾擊症狀之病患,包括39位經手術證實有 全層旋轉肌腱撕裂者及29位經手術證實無全層撕裂者。針對其旋轉肌腱夾擊症 的磁振影影表現作評估,包括滑液囊周邊脂肪層、肩峰下間距、肩峰形狀、肩 峰銷骨下區域、喙突肩峰韌帶、與肩峰下骨刺,並與全層旋轉肌腱撕裂之相互 關聯作研究。 結果 滑液囊周邊脂肪層之消失(p=0.0001),鉤狀肩峰(p=0.0148),肩峰鎖骨下 壓迫(p=0.0004),和窄小的肩峰下間距(p=0.0005)與全層旋轉肌腱撕裂有顯著的相 互關聯。然而,肩峰下骨刺(p=0.6238)和喙突肩峰韌帶之不規則增厚(p=0.1611)與 全層旋轉肌腱撕裂並無顯著之關聯。 結論 旋轉肌腱夾擊症的特定之磁振影像表現對於區別全層旋轉肌腱撕裂和非 全層撕裂之旋轉肌腱病灶是相當可靠及有幫助的,並且在術前就能非侵襲性地 來對旋轉肌腱手術治療的必要與否作決定。 |
英文摘要 | Background. Rotator cuff tears usually derive from shoulder impingement, and need surgical treatment. This study is to verify the Magnetic Resonance Image (MRI) findings of rotator cuff impingement which are related to full-thickness rotator cuff tear (FTRCT). Methods. Totally 68 patients with shoulder impingement syndrome were studied, including 39 shoulders with surgically-proven FTRCT, and 29 shoulders without FTRCT. MRI findings of shoulder impingement were evaluated for peribursal fat plane, subacromial distance, acromion shape, subacromioclavicular space, irregularity of coracoacromial ligament and presence of subacromial spurs. The correlation with FTRCT was also determined. Results. Peribursal fat plane obliteration (p = 0.0001), hook-shaped acromion (p = 0.0148), subacromioclavicular indentation (p = 0.0004), and decreased subacromial distance (p = 0.0005) showed significant correlation with FTRCT; however, subacromial spurs (p = 0.6238) and thickened irregular coracoacromial ligament (p = 0.1611) showed poor correlation. Conclusions. Specific MRI findings of rotator cuff impingement are fairly reliable and helpful for discrimination of FTRCT from non-FTRCT cases, and can be used preoperatively and noninvasively to determine the necessity of surgical repair of rotator cuff. |
