Foot Macrodactyly Associated with Klippel-Trenaunay Syndrome.

Klippel-Trenaunay syndrome is a rare congenital malformation which may be associated with macrodactyly. The main problem is the need for custom-made shoes. We describe the case of a female newborn affected by Klippel-Trenaunay syndrome, with a larger and longer right foot; the difference increased progressively and, at 5 years of age, the right foot was 50% larger and 38% longer than the left one. Due to the progression of the deformity, reduction surgery was advised to reduce the foot's width. Resection of the second ray and 2nd cuneiform was performed. The result was excellent and there were no complications during a 10-year follow-up period with a decrease of width and length difference to 10% and 4%, respectively, in comparison to the contralateral foot. There were no gait anomalies. Abnormal foot width and length represented the main problems and guided the surgical strategy. Second ray resection was effective, without complications and with a good long-term functional outcome. Possibility of wearing fashionable conventional shoes without insoles was achieved to the patient's satisfaction.
