The patients were 8 year-old boy and his 9 year-old sister with blood consanguity between their parents and grand parents.Case 1. T. O. male, age 8.Normal birth with slight varus deformity of his right ankle which healed by manual redression and three-months fixation in a plaster cast. Walking started at the age of 1 year 4 months, when his mother noticed of pes equinus of his feet which progressed by aging.His condition was normal in general but marked bilateral equinus deformity of about 160° plantar flexion. He stood on his toes only. No other neuro-muscular disorder was observed. Lengthening of the Achilles tendons about 10 centimeter with the posterior capsulotomy of the ankle resulted in satisfactory correction of the deformity and in good standing and walking on his heels.Case 2. Y. O. female, age 9.Normal birth. At the age of 1 year 3 months when she started walking, equinus deformity of her feet was noticed. Deformity was less severe than that of her brother. Three centimeter lengthening of the Achilles tendons corrected the deformity.In those two cases no cause which resulted in the equinus deformity was discovered and these deformities were noticed when they started walking. Therefore, the cases might belong to the category of congenital pes equinus.
