Abstract

Recurrent varus deformity and shortening frequently result following valgus osteotomy alone for advanced stage infantile tibia vara (ITV), due to the proximal medial physeal dysfunction which resembles a complete growth arrest in Langenskiöld grade III or greater lesions. Epiphysiolysis is a possible treatment alternative which, if successful, can restore symmetric proximal tibial growth and obviate the need for additional complex treatments to address recurrent angular deformity and limb length inequality. We reviewed 24 patients, ages 5-10 years, with 27 affected tibiae, who underwent epiphysiolysis of the proximal medial tibia combined with valgus osteotomy. The procedure was >80% successful in restoring growth and avoiding varus recurrence in children <7 years old. Patients >age 7, patients with relative undercorrection of their mechanical axis at the time of surgery, and patients with previous failed surgical treatment were more likely not to benefit from epiphysiolysis, and consequently alternative methods may be more appropriate.
