目的 分析肱骨外上髁炎的MRI影 像表现及诊疗的临床价值。方法 选择经 我院临床确诊的肱骨外上髁炎患者46例 (共48个肘关节)为研究对象，对其进行冠 状面、横断面和矢状面T1 FSE系列和T2 FS FRFSE系列扫描，分析肱骨外上髁炎的 MRI影像表现以及伸肌总腱与桡侧尺副韧 带损伤程度的相关性。结果 按照伸肌总 腱损伤程度进行分级，轻度损伤者20例， 中度损伤者14例，重度损伤者14例，MRI 表现为肱骨外上髁与伸肌总腱之间条片状 稍高信号；44例合并桡侧尺副韧带损伤， 按照桡侧尺副韧带损伤程度分级，轻度损 伤者18例，中度损伤者12例，重度损伤者 14例，MRI影像可见冠状位T2WI桡侧尺副 韧带中断，可见水样高信号；16例患者合 并桡侧副韧带损伤，MRI影像可见冠状位 T2WI脂像，桡侧副韧带中断，横过韧带水 样高信号；伸肌总腱损伤程度与桡侧尺副 韧带损伤程度呈正相关的关系(rs＞0)。 结论 肱骨外上髁炎伸肌总腱损伤的同时 还伴有其它多种损伤，伸肌总腱损伤程度 加重，桡侧尺副韧带损伤程度也会加重。

Objective Analysis on outside humerus condyle inflammation of the clinical value of MRI imaging manifestations and diagnosis and treatment. Methods Choose the hospital clinical diagnosed on the outside of the humerus condyle inflammation in patients with 46 cases (48 elbow) as the research object, on the coronal and transverse and sagittal T1 and T2 FSE series series of FS FRFSE scanning, analysis on the humerus outside the MRI imaging performance of condyle infection and total extensor tendon and lateral radial ulnar collateral ligament damage degree of correlation. Results Carried out in accordance with the total extensor tendon damage degree classification, mild damage to 20 cases, 14 cases of moderate damage, severe injury of 14 cases, MRI outside epicondyle of the humerus and extensor tendon always between the shape slightly high signal; 44 cases of merger called lateral ulnar collateral ligament injury, according to the radial side of the ulnar collateral ligament injury classification, mild damage of 18 cases, 12 cases were moderate damage, severe injury of 14 cases, MRI image visible coronary a T2WI called lateral ulnar collateral ligament disruption, visible water high signal; 16 patients merge called lateral collateral ligament injury, MRI image visible coronal T2WI fat like, called lateral collateral ligament disruption, cross ligament water high signal; Total extensor tendon damage degree and radial lateral ulnar collateral ligament damage degree were positively correlated (rs＞0) the relationship between. Conclusion Outside on the humerus condyle inflammation of the extensor tendon injury always accompanied by a variety of other damage at the same time, the total extensor tendon damage degree aggravating, called lateral ulnar collateral ligament damage degree will also increase.
