Abstract Background Lumbar kyphosis is a complex spinal deformity occurring in approximately 8% to 20% of patients with myelomeningocele. The resulting gibbosity may cause pressure ulcers, difficulty lying down the supine position and sitting on ischia without support, decreasing quality life (QOL). Surgery generally performed correct maintain vertebral alignment, but high complication rates have been reported. Despite satisfactory radiological results, impact surgery its complications...
