Shortening Scarf Osteotomy for Macrodactyly and Valgus of the Hallux in Acrodysostosis Lesser Toes Brachydactyly

Acrodysostosis is a rare syndrome of peripheral dysostosis, neurodevelopment delay, and skeletal abnormalities. The most common bone changes are peripheral dysostosis with severe brachydactyly of the lesser toes. The first ray of the feet is often not affected or may present hyperplasia resulting in an unbalanced transverse arch of the forefoot, with potential negative effects on function. Additionally, the insufficiency of the lesser toes may be associated with complex congenital hallux valgus deformities. Surgical approaches include growth plate epiphysiodesis, bulk reduction procedures, bone shortening, osteotomies, or amputation. Here, we report a case of a 14-year-old girl with acrodysostosis and severe discrepancy of the first ray and hallux valgus deformity simultaneously treated by a modified scarf osteotomy.
