BACKGROUND: The conservative and surgical management of lumbar kyphosis is difficult and is a challenge for the orthopaedic surgeon. A kyphotic deformity of the lumbar spine is present in 8% to 20% of these patients. Most curves have very rigid components, often exceed 80 degrees at birth. The options for conservative management are limited. Bracing is extremely difficult, rarely effective, and in advanced stages impossible. We have been using the Warner and Fackler kyphectomy technique at our institution since 1994 as a standard procedure for treating children with lumbar kyphosis due to myelomeningocele. RESULTS: This study was performed for a better understanding of the cause of the complications and optimizing the surgical technique. AIM: The aim of this study was to evaluate the longterm results, technical problems, early and late complications and the complication associated risk factors.
