Cost effectiveness analysis of graft options in spinal fusion surgery using a Markov model.
Statistical decision model. ⋯ RhBMP is the most cost-effective graft option for L4-L5 fusion for degenerative spondylolisthesis largely due to the reduced rate of revision spine surgery. The increased upfront cost and list of complications associated with RhBMP is offset by the reduced rate of revision surgery.

Acute hospital costs after minimally invasive versus open lumbar interbody fusion: data from a US national database with 6106 patients.
Retrospective multi-institutional database review. ⋯ This data from a large nationwide sample of hospitalizations demonstrates that MIS lumbar interbody fusion results in a statistically significant reduction in hospital LOS and a reduction in total hospital costs with 2-level surgery after adjusting for significant covariates. The majority of cost savings from MIS surgery were due to more rapid mobilization and discharge, as well as a reduction in outliers with extended hospitalizations.

Comparative StudyA comparison of anterior and posterior instrumentation for restoring and retaining sagittal balance in patients with idiopathic adolescent scoliosis.
Retrospective, comparative study. ⋯ Anterior solid rod-screw instrumentation results in shorter fusion segments, and better sagittal alignment and quality of life than posterior pedicle screw instrumentation in patients with Lenke type 5 AIS.

Nucleoplasty is effective in reducing both mechanical and radicular low back pain: a prospective study in 87 patients.
A prospective study of all patients with either mechanical back pain or radicular back pain who underwent nucleoplasty and were followed up prospectively. ⋯ We concluded that the nucleoplasty technique is a safe and effective procedure for radicular or combined radicular and mechanical low back pain and should be used in selected cases before open surgery after conservative treatment has failed.

Comparative StudyKyphoplasty versus vertebroplasty: restoration of vertebral body height and correction of kyphotic deformity with special attention to the shape of the fractured vertebrae.
Retrospective comparative analysis. ⋯ KP has a significant advantage over VP in terms of kyphosis correction, vertebral height restoration, and cement leakage prevention. KP has an obvious advantage in terms of middle vertebral height restoration and cement leakage prevention, especially for V-shape compression fractures.
