To determine the value of magnetic resonance (MR) imaging in the clinical management of chronic refractory lateral epicondylitis.
Coronal three-dimensional Fourier transform, multiplanar gradient-recalled-echo, and fat-suppressed sagittal images were obtained in 33 patients. Twenty of these patients underwent surgical débridement and/or primary tendon repair and were included in the correlative study. Surgical and pathologic reports were reviewed to determine the location and gross characteristics of the tissue.
Findings at MR imaging correlated with the surgical findings of primary degeneration of the extensor carpi radialis brevis (n = 20). Histopathologic examination demonstrated neovascularization, disruption of collagen, and mucoid degeneration without inflammation.
The use of MR imaging in patients with recalcitrant lateral epicondylitis assists in surgical planning. The definition of tendon degeneration and degree of tear, as depicted on MR images, correlate well with surgical and histologic findings.
确定磁共振（MR）成像在慢性难治性外侧上髁炎临床管理中的价值。
对33例患者进行了冠状位三维傅里叶变换、多平面梯度回波和脂肪抑制矢状位成像。其中20例患者接受了手术清创和/或原发性肌腱修复，并纳入相关性研究。回顾手术和病理报告以确定组织的位置和大体特征。
MR成像结果与桡侧腕短伸肌原发性退变的手术结果相关（n = 20）。组织病理学检查显示有新生血管形成、胶原破坏和黏液样变性，无炎症。
在难治性外侧上髁炎患者中使用MR成像有助于手术规划。MR图像上显示的肌腱退变和撕裂程度与手术和组织学结果密切相关。
