    Abstract:
    OBJECTIVE: To analyze the clinical characteristics of 73 cases of macrodactyly. METHODS: Review the incidence, distribution, characteristic, X-rays, pathogenesis and treatment of involved digits on the base of the clinical documents of 73 macrodactyly which were treated from 1965 to 2006. Twenty-eight cases had been followed-up. RESULTS: Unilateral involved 71 cases, bilateral involved 2 cases. In upper deformities, the most involved digit was the index finger, followed by thumb and middle finger enlargement. In lower deformities, the second toes were affected more. There were 12 cases of static macrodactyly, which were all presented at or soon after birth. Sixty-one cases were progressive macrodactyly: 39 cases presented at birth; 17 cases occurred at about 2 years old; 5 cases were found after age 2. Thirty-seven cases of progressive type presented digital deviation; 3 cases associated with syndactyly; 16 cases complicated with thenar eminence hypertrophy; 8 cases of multiple-digit involved combined with palm and forearm hyperplasia. CONCLUSIONS: Macrodactyly in hand has a preference for the median nerve territory, mainly involving index, thumb and middle finger. Pedal macrodactyly prefers medial plantar nerve territory, the second toe is the most commonly affected. The progressive macrodactyly is more common than static. It may present at birth and combine with syndactyly, digital deviation, thenar eminence hypertrophy, palm and forearm hyperplasia.
