title: Hemiepiphyseal stapling for knee deformities in children younger than 10 years: a preliminary report.
abstract: Epiphyseal stapling, which is the only reversible method of growth alteration, has traditionally been reserved for teenagers. We are reporting the application of hemiepiphyseal stapling in a series of 25 children younger than 10 years. With a variety of underlying diagnoses, three children had genu varum and 22 had genu valgum. The technique involved fluoroscopic localization of all growth plates and careful preservation of the periosteum while inserting (and subsequently removing) one or two staples per physis. The mean age at stapling was 6 years + 4 months. Follow-up averaged 3 years + 3 months. The anatomic (tibiofemoral) angle and mechanical axis improved in all patients. One staple broke on removal; there were no other hardware failures. We conclude that hemiepiphyseal stapling is a safe and effective treatment for children younger than 10 years who have angular deformities of the knee. No growth-plate arrests have occurred. In the event of recurrent deformity, stapling may be repeated.
