We performed andterior transfer of the toe flexors in 9 patients (10 feet) with paralytic pes equino-varus. Seven cases were due to cerebral palsy and three were caused by peroneal palsy resulting from truma.The follow-up period ranged from 6 months to 3 years, with an avarage of one year and 6 months.We evaluated clinical results and active and passive montion.Six feet were judged to be good perfect correction, three cases still had a slight pes equinus defomity and an equinus deformity recurred in one foot. Nine of 10 feet achieved stisfactory results on the physical evaluation. On walking, 7 feet demonstrated the so-called heel-toe pattern.Preoperatively the mean plantar flexion had been 43.9 degrees, and dorsiflexion was -38.3 degrees. Postopertively the mean plantar flexion was 27.2 degrees, and dorsiflexion was -4.2 degrees. Therefore, the active range of motion improved from 5.6 degrees to 23 degrees on average.
