There is increasing awareness of adult degenerative or de novo scoliosis, and its surgical treatment when indicated can be challenging and resource intense. Surgical randomized controlled trials are rare, and observational studies pose limitations because of the heterogeneity of surgical practices, techniques, and patient populations. Pooled analysis of current literature may identify effective treatment strategies and guide future efforts at prospective clinical research. This study aimed to synthesize existing data on the outcomes of surgical intervention for adult degenerative scoliosis. ⋯ Exhaustive literature review yielded 24 studies reporting preoperative and postoperative data regarding the surgical treatment of adult degenerative scoliosis. No randomized clinical trials (RCTs) were identified. Despite heterogeneity, a limited meta-analysis showed significant improvement in Cobb angle, coronal balance, and VAS after surgical treatment of adult degenerative scoliosis.

Retrospective, matched cohort. ⋯ Adolescent idiopathic scoliosis and spondylolisthesis can be treated independently. Powerful curve corrections can be obtained and maintained for at least 4 years in patients with AIS regardless of the presence of spondylolisthesis. Preserving motion of 3 levels between a posterior spinal fusion for AIS and a spondylolisthesis does not contribute to slip progression. According to SRS-22 questionnaire data, patients with concomitant AIS and spondylolisthesis who undergo spinal fusion procedures do well clinically.

Case series. ⋯ Hooks can migrate and potentially cause neurologic impairment and pain long after index surgery, despite the presence of solid spinal fusion. We believe this is partly the result of the surgical technique we used and have since abandoned, and partly the proximal spine settling and fusion mass deformation over time, which we call "proximal junctional scoliosis." We recommend computed tomographic imaging in case of postoperative symptoms and removal of hooks in case of hook migration into the spinal canal.

Prospective questionnaire administration study. ⋯ Scoliosis Research Society-24 can be converted to SRS-22r scores with fair accuracy in the surgical-range, medical/interventional AIS patient population for total score, and total pain domains. The SRS-24 translates unacceptably to the SRS-22r in self-image, function, and satisfaction domains. The SRS-24 to SRS-22r conversion equations are similar to operative AIS patients, except for the function domain. Caution should be used when interpreting results based on translation of SRS-24 to SRS-22r values.

The use of preoperative halo-gravity traction (HGT) improves both spinal deformity and pulmonary function and is a helpful adjuvant in the treatment of complex spinal deformity. Despite the benefits of preoperative HGT, there is no consensus on the optimal traction protocol. ⋯ We found that preoperative HGT is a safe and useful adjuvant to the treatment of patients with severe scoliosis. Significant deformity correction averaging 35% percent can be expected, with the majority of deformity correction occurring after 3 to 4 weeks. In the majority of patients, this correction is maintained or even improved with subsequent surgical correction.
