Abstract

The purpose of the study was to investigate the relationship between diffusion tensor imaging (DTI) and the clinical classification of cubital tunnel syndrome (CuTS). Ten patients with CuTS (7 men and 3 women; mean age: 52.7 years) and 5 patients without ulnar neuropathy (2 men and 3 women; mean age: 38.0 years) were enrolled in this retrospective study. Fifteen patients were clinically classified into three groups: "Normal", "1 and 2A", and "2B and 3" by an orthopedic surgeon using the modified McGowan stages. DTI was acquired using a 3.0-T MRI. Fractional anisotropy (FA) of the ulnar nerve was measured in slices covering 20 mm proximal to 20 mm distal to ulnar sulcus. Median FA values in each group were compared by Kruskal-Wallis and Steel-Dwass test (P < 0.05). Five patients with CuTS were classified as "1 and 2A" and five patients as "2B and 3". The FA values, proximal 12 mm to the ulnar sulcus were 0.486 ± 0.117, 0.425 ± 0.166 and 0.298 ± 0.0386 in the "Normal", "1 and 2A" and "2B and 3" groups, respectively. The FA values of patients classified as "Normal" were significantly higher than those classified as "2B and 3" (P = 0.0326 in Steel-Dwass test). FA proximal to the ulnar sulcus might be associated to the modified McGowan stages for the clinical classification of CuTS.

弥散张量成像与肘管综合征临床分类之间的关系。
本研究旨在探讨弥散张量成像(DTI)与肘管综合征(CuTS)临床分类之间的关系。这项回顾性研究共纳入了 10 名 CuTS 患者(7 名男性和 3 名女性;平均年龄:52.7 岁)和 5 名无尺神经病变的患者(2 名男性和 3 名女性;平均年龄:38.0 岁)。15 名患者被临床分为三组:骨科医生采用改良麦高文分期法将 15 名患者临床分为三组:"正常"、"1 和 2A "以及 "2B 和 3"。DTI 采用 3.0-T 磁共振成像采集。尺神经的分数各向异性(FA)是在尺神经沟近端 20 毫米至远端 20 毫米的切片上测量的。通过 Kruskal-Wallis 和 Steel-Dwass 检验比较了各组的中位 FA 值(P<0.05)。
