Comparative Study
Changes in physical function after palliative surgery for metastatic spinal tumor: association of the revised Tokuhashi score with neurologic recovery.
A retrospective study of patients undergoing palliative surgery for metastatic spinal tumors. ⋯ Palliative surgery benefited half of the patients with metastatic spinal tumor, with a greater probability of benefit found in persons with a higher total revised Tokuhashi score (score 9-15) and/or primary cancers with longer survival times.

Comparative Study
Postural model of sagittal spino-pelvic alignment and its relevance for lumbosacral developmental spondylolisthesis.
Comparative study of sagittal spino-pelvic alignment in children and adolescents with developmental lumbosacral spondylolisthesis compared with asymptomatic subjects. ⋯ Children and adolescents stand with a relatively constant global sagittal spino-pelvic alignment, regardless of the local lumbosacral deformity. A normal posture is maintained in low-grade spondylolisthesis and in high-grade spondylolisthesis with a balanced sacro-pelvis. Posture is abnormal in high-grade spondylolisthesis associated with a retroverted sacro-pelvis, suggesting that surgical reduction of the local lumbosacral deformity in these patients could be attempted to restore a normal posture.

Randomized Controlled Trial Multicenter Study Comparative Study
The MRC spine stabilization trial: surgical methods, outcomes, costs, and complications of surgical stabilization.
A review of the surgical costs and results in a group of patients randomly allocated to surgery as part of a large prospective randomized trial of patients with chronic back pain. ⋯ These observational changes in the ODI after surgery are similar to those reported from other studies of spinal fusion. More complex surgery is more expensive with more complications than postero-lateral fusion.

Comparative Study
Blood conservation techniques in spinal deformity surgery: a retrospective review of patients refusing blood transfusion.
A retrospective review. ⋯ These blood conservation techniques allow satisfactory completion of deformity surgery on those patients not willing to be transfused and without major anesthetic or medical complications.
