Madelung's deformity: diagnostic thresholds of radiographic measurements.

Purpose: Although the x-ray changes of advanced Madelung's deformity are well described, little quantitative information exists on the subtle, early changes of the deformity. This study investigated the threshold of 4 radiographic measurements that predict a diagnosis of Madelung's deformity by experienced hand surgeons.

Methods: Ulnar tilt, lunate subsidence, lunate fossa angle, and palmar carpal displacement were measured on x-rays of patients with Madelung's deformity.

Madelung's deformity: quantitative radiographic comparison with normal wrists.

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.

Madelung's deformity: quantitative assessment of x-ray deformity.

Purpose: To evaluate 5 defined measurement techniques that are applicable to x-rays of Madelung's deformity: ulnar tilt, lunate subsidence, lunate fossa angle, palmar tilt, and palmar carpal displacement. The measurements rely on the longitudinal axis of the ulna and the carpal bones to determine drawing lines and avoid the distorted distal radius and its deformed lunate fossa. The reliability and reproducibility of the measurements is determined.

Joseph H. Boyes, MD, 1905-1995: a driving force in American hand surgery.

Joseph H. Boyes, MD (1905-1995) was an important figure in American Hand Surgery. He was a pivotal founder of the American Society for Surgery of the Hand (ASSH), he trained a number of hand fellows, he was active for many years at national and international hand meetings, and he was the founding editor of the Journal of Hand Surgery.
