Innovative treatment for pes cavovarus: a pilot study of 13 children

Background and purpose — Pes cavovarus (PCV) is a complex deformity, frequently related to neurological conditions and associated with foot pain, callosities, and walking instability. The deformity has the tendency to increase during growth. Orthotic treatment is ineffective and surgery may be troublesome. We present the preliminary results of a new mini-invasive surgical technique for correction of this foot deformity.Patients and methods — We operated on 13 children (24 feet), age 7–13 years. In 7 children the deformity was neurological in origin. The surgical technique included a dorsal hemiepiphysiodesis of the 1st metatarsal, and a plantar fascia release. The clinical deformity, hindfoot flexibility, and foot callosities, together with a radiological assessment (Meary angle, calcaneal pitch, and talo-calcaneal angle), was done pre- and postoperatively. At final check-up, after a median of 28 months (12–40), the Oxford Ankle Foot Questionnaire for children (OXAFQ-C) was used to assess patient satisfac...
