The association of the severity of clinical symptoms and level of functional performance with the degree of magnetic resonance imaging abnormalities in patients with lateral epicondylitis has not been fully elucidated. This study aimed to investigate the association between the degree of anatomical abnormalities by evaluating three-dimensional magnetic resonance imaging models of the common extensor tendon and clinical parameters in patients with lateral epicondylitis.
A total of 61 patients (24 men and 37 women) with lateral epicondylitis were included in this study. 3-Tesla magnetic resonance imaging was performed for all patients, and clinical parameters, including pain visual analog scale score, Quick Disabilities of Arm, Shoulder and Hand questionnaire score, elbow range of motion, and demographic factors, were evaluated. The proportion of lesion volume of common extensor tendon was adopted for three-dimensional model analysis. To determine the factors associated with clinical parameters, univariate, and multivariate linear regression analyses were performed.
The proportion of lesion volume of common extensor tendon was not associated with clinical parameters. Gender and muscle edema were independently associated with pain visual analog scale scores. However, demographic factors and magnetic resonance imaging abnormalities were not associated with the Quick Disabilities of Arm, Shoulder, and Hand questionnaire score or elbow range of motion.
The three-dimensional volumetric lesion size of common extensor tendon was not associated with clinical symptoms and functional performance in patients with lateral epicondylitis. The clinical parameters of lateral epicondylitis may be influenced by several factors.
外侧肱骨上髁炎患者的临床症状严重程度和功能表现水平与磁共振成像异常程度之间的关系尚未完全阐明。本研究旨在通过评估外侧肱骨上髁炎患者的伸肌总腱三维磁共振成像模型，探讨解剖学异常程度与临床参数之间的关系。
本研究共纳入 61 例外侧肱骨上髁炎患者（24 名男性，37 名女性）。所有患者均进行 3.0T 磁共振成像检查，并评估临床参数，包括疼痛视觉模拟评分、上肢功能障碍问卷评分、肘部活动范围和人口统计学因素。采用伸肌总腱病变体积比例进行三维模型分析。为了确定与临床参数相关的因素，进行了单变量和多变量线性回归分析。
伸肌总腱病变体积比例与临床参数无关。性别和肌肉水肿与疼痛视觉模拟评分独立相关。然而，人口统计学因素和磁共振成像异常与上肢功能障碍问卷评分或肘部活动范围无关。
外侧肱骨上髁炎患者伸肌总腱的三维容积病变大小与临床症状和功能表现无关。外侧肱骨上髁炎的临床参数可能受多种因素影响。
