Abstract

OBJECTIVE

The aim of the study was to investigate the 3.0 Tesla magnetic resonance imaging (MRI) features of Madelung's deformity.

MATERIALS AND METHODS

The wrist MRI scans of 19 patients clinically diagnosed with Madelung's deformity and 20 patients without deformity were consecutively selected from Beijing Jishuitan Hospital between April 2019 and December 2022 for observation, in the case group and control group, respectively. Multiple linear regression was used to analyze the factors affecting tilting angle and width of central disc (CD, also termed as triangular fibrocartilage, the main component of triangular fibrocartilage complex), while the chi-square test was used to compare the occurrences of CD (radial) attachment displacement, VL, and RTL. p < 0.05 indicated statistical significance.

RESULTS

Madelung's deformity significantly contributed to the tilting and thickening of the CD. In the case group, the tilting angle and thickness of CD were (51.46 ± 1.33)° and (0.23 ± 0.01) cm, respectively, which was statistically significant (p < 0.05); the radial attachment of the CD significantly shifted away from the distal articular surface level (χ = 39.00, p < 0.001), with a mean displacement of (0.97 ± 0.38) cm. Furthermore, the cases demonstrated abnormally developed Vickers ligament (χ = 35.19, p < 0.001) and radiotriquetral ligament (χ = 25.66, p < 0.001).

CONCLUSION

MRI provides a notable advantage in diagnosing Madelung's deformity. Compared with the control group, patients with Madelung's deformity exhibited tilting and thickening of the CD. Additionally, the radial attachment of the CD was significantly shifted proximally with abnormal development of Vickers and radiotriquetral ligaments.

摘要

目的

本研究旨在探讨马德隆畸形的 3.0 特斯拉磁共振成像（MRI）特征。

材料和方法

连续选取 2019 年 4 月至 2022 年 12 月期间在北京积水潭医院临床诊断为马德隆畸形的 19 例患者和 20 例无畸形患者的腕关节 MRI 扫描结果进行观察，分别纳入病例组和对照组。采用多元线性回归分析影响中央盘（CD，亦称三角纤维软骨，三角纤维软骨复合体的主要成分）倾斜角和宽度的因素，采用卡方检验比较 CD（桡侧）附着点移位、Vickers 韧带和桡侧三角韧带（RTL）的发生情况。p<0.05 表示具有统计学意义。

结果

马德隆畸形显著导致 CD 的倾斜和增厚。在病例组中，CD 的倾斜角和厚度分别为（51.46±1.33）°和（0.23±0.01）cm，差异具有统计学意义（p<0.05）；CD 的桡侧附着点明显从远侧关节面水平向近端移位（χ²=39.00，p<0.001），平均移位距离为（0.97±0.38）cm。此外，病例组还表现出异常发育的 Vickers 韧带（χ²=35.19，p<0.001）和桡侧三角韧带（χ²=25.66，p<0.001）。

结论

MRI 对马德隆畸形的诊断具有显著优势。与对照组相比，马德隆畸形患者的 CD 存在倾斜和增厚，CD 的桡侧附着点明显向近端移位，同时伴有 Vickers 和桡侧三角韧带的异常发育。
