Purpose. Angular deformity in the lower extremities can result in pain, gait disturbance, cosmetic deformity and joint degeneration. Up until the introduction of guided growth in 2007, which has since become the gold standard, treatment for correcting angular deformities in skeletally immature patients had been either an osteotomy, a hemiepiphysiodesis, or the use of staples. Methods. We reviewed the surgical records and diagnostic imaging in our childrens hospital to identify all patients who had guided growth surgery since 2007. All patients were followed until skeletal maturity or until their metalwork was removed. Results. 113 patients, with 147 legs were assessed for eligibility. Three were excluded for various reasons including inadequate follow-up or loss of records.
