title: Madelung's deformity: quantitative radiographic comparison with normal wrists.
abstract: Four measurements, ulnar tilt, lunate subsidence, lunate fossa angle and palmar carpal displacement, on wrist radiographs of 26 patients with Madelung's deformity and 48 normal subjects were compared. The range of measurements on wrists with Madelung's deformity was wider than on normal wrists, with severe deformities having very abnormal values. Some Madelung's patients had values that were within the normal range for each of the four measurements. Measurement of the lunate fossa angle demonstrated the least overlap between normal wrists and wrists of patients with Madelung's deformity with only two in the normal range. A lunate fossa angle over 29 degrees may help identify early Madelung's deformity.
