Scarf osteotomy of hallux valgus in children and adolescents

Purpose of the study The aim of this study was to analyze the results of surgical treatment of hallux valgus using scarf osteotomy in children and adolescents. Material and method Twelve children and adolescents (19 feet) operated on with scarf osteotomy were reviewed retrospectively with a mean follow-up of 15 months. Clinical and radiographic results were assessed. Results We obtained 10 good results (asymptomatic cases), 9 poor with residual symptoms such as pain or cosmetic problems. Two populations could be identified considering the metatarsus varus and distal metatarsal angle. Those with metatarsus varus greater than or equal to 10 degrees or normal distal metatarsal angle had good results. Those without metatarsus varus had poor results. There was no disturbance of growth. Discussion Scarf osteotomy can be used in children without risk of hindering growth. Nevertheless, good results can be achieved only in cases of true metatarsus varus and normal distal metatarsal angle. In other cases, a different osteotomy of the first metatarsal would be preferable.
