Comparative Study
Preventive effect of artificial ligamentous stabilization on the upper adjacent segment impairment following posterior lumbar interbody fusion.
A retrospective, comparative study. ⋯ These results demonstrated an effect of soft stabilization for the prevention of transition syndrome in lumbar spine fusion. Although the postoperative follow-up periods in this study were not sufficiently long to reach a definitive conclusion, intervertebral breakdown adjacent to the rigid spine fusion could be diminished by the application of soft stabilization.

Randomized Controlled Trial
A comparison of posterolateral lumbar fusion comparing autograft, autogenous laminectomy bone with bone marrow aspirate, and calcium sulphate with bone marrow aspirate: a prospective randomized study.
A prospective clinical study. ⋯ ICBG performs as expected with high fusion rates and laminectomy bone with BMA performs equally as well. Osteoset is significantly inferior to ICBG despite the addition of BMA, which is osteoinductive and has improved fusion rates and osteogenesis in other models.

Comparative Study
Degenerative spondylolisthesis in patients with neurogenic claudication effects functional performance and self-reported quality of life.
The effect of degenerative spondylolisthesis on functional performance and self reported quality of life in patients with lumbar spinal stenosis was compared to patients with lumbar spinal stenosis and no degenerative spondylolisthesis. ⋯ The presence and magnitude of degenerative spondylolisthesis does not correlate with decreased functional capacity. The Swiss Spinal Stenosis Questionnaire and Short Form 36 are accurate in defining the functional status of a patient. Comprehensive evaluation of patients with symptomatic lumbar spinal stenosis using functional assessment and self-assessment questionnaires are helpful in determining the severity of a patient's disability. Plain radiographs may be valuable adjuncts for surgical decision-making, but are not useful in quantifying the degree to which a patient is impaired.

Questionnaire survey. ⋯ North American orthopedic surgeons' attitudes toward chiropractic range from very positive to extremely negative. Improved interprofessional relations may be important to ensure optimal care of shared patients.

A historical cohort study. ⋯ Good reproducibility and agreement using the first and second vertebrae above the UIV to measure the angle of PJK was found in this study.
