PURPOSE
To establish whether Madelung's deformity demonstrates a radiographic continuum of severity and whether a forme fruste does exist.
METHODS
Ulnar tilt, lunate subsidence, palmar carpal displacement, and lunate fossa angle were measured in 81 wrist radiographs with obvious or suspected Madelung's deformity. Statistical analyses based on these measurements were performed to ascertain if there is a deformity continuum.
RESULTS
Ranges of 15 degrees to 51 degrees (mean, 28 degrees) for ulnar tilt, -7 to +11 mm (mean, -0.8 mm) for lunate subsidence, 9 to 25 mm (mean, 15.3 mm) for palmar carpal displacement, and 20 degrees to 56 degrees (mean, 33 degrees) for lunate fossa angle were obtained. Significant correlations were observed between all measurements.
CONCLUSIONS
Madelung's deformity encompasses a spectrum of radiographic abnormality.
TYPE OF STUDY/LEVEL OF EVIDENCE: Diagnostic I.
目的
确定马德隆畸形是否呈现出影像学上严重程度的连续变化，以及是否存在顿挫型。
方法
对81张有明显或疑似马德隆畸形的腕部X线片测量尺骨倾斜度、月骨下沉、腕骨掌侧移位和月骨窝角。基于这些测量结果进行统计分析，以确定是否存在畸形连续变化。
结果
尺骨倾斜度范围为15度至51度（平均28度），月骨下沉为-7至+11毫米（平均-0.8毫米），腕骨掌侧移位为9至25毫米（平均15.3毫米），月骨窝角为20度至56度（平均33度）。所有测量结果之间均观察到显著相关性。
结论
马德隆畸形包含一系列影像学异常。
研究类型/证据水平：诊断性研究I级。
