LONG-TERM RESULTS OF SURGICAL-TREATMENT FOR MACRODACTYLY OF THE HAND

A retrospective review was performed for 23 patients who were surgical ly treated for macrodactyly of the hand between 1964 and 1995. Treatme nt regimens varied among the patients, and more than two operative pro cedures were performed in 65 percent of the patients. At final follow- up, the average length of the affected digits was 102 percent of that of the normal contralateral side. The average circumference of the dig its was 121 and 124 percent at the proximal interphalangeal and distal interphalangeal joints, respectively. The average range of motion was 65, 57, and 37 degrees at the metacarpophalangeal, proximal interphal angeal, and distal interphalangeal joints, respectively. Although it i s difficult to compare treatment regimens, epiphysiodesis/epiphysectom y was quite effective in the prevention of longitudinal overgrowth of the digits, but resection of the hypertrophic nerves was unsuccessful in preventing finger overgrowth.
