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° to 51° (mean, 28°) 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° to 56° (mean, 33°) for lunate fossa angle were obtained. Significant correlations were observed between all measurements.

Conclusions

Madelung's deformity encompasses a spectrum of radiographic abnormality.
