肱骨上髁炎的磁共振诊断价值

Humeral epicondylitis of diagnostic value of MRI

目的:评价磁共振成像(MRI)在肱骨内、外上髁炎的诊断价值。方法:回顾分析12例肱骨内、外上髁炎病变患者的MRI图像。部分患者与关节手术对照。结果:12例患者中,1例同时患有内、外上髁炎;余11例中,内上髁炎1例,外上髁炎10例;10例外上髁炎显示伸肌总腱增粗,其内不规则高信号,伴或不伴周围程度水肿,其中2例可见肱骨外上髁局部信号异常,1例伴外侧副韧带部分撕裂;2例内上髁炎显示屈肌总腱增粗,伴有信号增高,肱骨内上髁未见明显异常。结论:MRI能显示肌腱的急慢性损伤,显示骨髓水肿,同时,MRI有助于正确诊断和了解较为复杂的肘关节损伤。

Objective：To evaluate MRI in diagnosis for humeral epicondylitis.Methods：Analyzing the MR images of 12 patients who suffered epicondylitis retrospectively.The analyzing results were compared with those of operation or arthroscopy.Results：Among these patients,one patient was confirmed medial humeral epicondylitis and lateral humeral epicondylitis simultaneously,ten patients were confirmed lateral epicondylitis,one patient was confirmed medial epicondylitis.The tendons origin at the lateral or medial epicondyles thickened and showed increased signal intensity on all pulse sequence.One patient suffered from the lateral epicondylitis with the lateral ulnar collateral ligament partial teared.Conclusion：MRI can show the acute and chronic injuries of tendons and the edema of the marrow.Meanwhile,MRI is helpful to evaluate the complex elbow injuries.
