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.

Original article ⋯ The effect of TDR on sagittal balance appears favorable with an increase in global and segmental lumbar lordosis after single level TDR for degenerative disc disease. The degree of postoperative angle of lordosis was not affected by the angle of implant chosen at the operated level and varied independently of the implant angle.

Comparative StudyStand-alone anterior versus anteroposterior lumbar interbody single-level fusion after a mean follow-up of 41 months.
Prospective cohort study comparing evaluations of single-level anterior lumbar interbody fusion (ALIF) versus anteroposterior lumbar fusion (APLF). ⋯ Stand-alone ALIF leads to better clinical results than APLF, without differences in fusion rates after 41 months. Therefore, when a posterior approach is not needed for decompression or reposition, we suggest performing a stand-alone ALIF in cases with single-level DDD.

Comparative StudyLoss of correction in the treatment of thoracolumbar kyphosis secondary to ankylosing spondylitis: a comparison between Smith-Petersen osteotomies and pedicle subtraction osteotomy.
Retrospective comparison of database patients. ⋯ Both SPOs and PSO showed similar effect in correcting the thoracolumbar kyphosis secondary to AS. However, patients treated with the SPOs technique showed higher risk in loss of correction in the instrumented region.
