title: Operative management of degenerative scoliosis: an evidence-based approach to surgical strategies based on clinical and radiographic outcomes.
abstract: Degenerative scoliosis is a common and important cause of lumbar spine deformity in the adult. The operative management of degenerative scoliosis encompasses a spectrum of approaches, including decompression alone, or fusion that may include posterior or anterior approaches. There exists significant variability in surgical approaches to degenerative scoliosis, and evidence to support a specific approach is limited. Including the structural thoracic spine in fusions to the thoracolumbar junction has a lower rate of revision than fusions with a cephalad segment at T12 or L1. Short fusions to L5 have a low rate of revision at a minimum follow-up of 2 years. Combined anterior and posterior surgery is more effective in improving lordosis than posterior-only surgery without osteotomies. Clinical outcomes of surgery for degenerative scoliosis are variable, andwct 2 self-reported scores for pain improve more reliably than scores for function. Further investigation, including comparison of randomized or matched cohorts and measurement of outcomes related to specific preoperative complaints, will be useful in the development of an evidence-based approach to degenerative scoliosis.
