Longitudinal cohort. ⋯ Patients with lumbar degenerative disorders have health state values similar to patients with chronic renal disease, Crohn's disease, or coronary artery disease. Health state values of patients with different indications for surgery differ at baseline and after surgery. Revision cases have worse baseline SF-6D scores and less improvement in scores at 2 years after surgery than primary cases. Further studies are needed to gain a greater understanding of health state utility values in patients with lumbar degenerative disorders.

Comparative Study
Gender difference in association between low back pain and metabolic syndrome: locomotive syndrome and health outcome in Aizu cohort study (LOHAS).
Cross-sectional survey. OBJECTIVE.: To investigate the relationship between low back pain (LBP) and metabolic syndrome (Mets) in community-based Japanese subjects. SUMMARY OF BACKGROUND DATA.: Relatively few reports have demonstrated a relationship between general pain and Mets, and none have addressed the relationship between LBP and Mets. ⋯ We observed a tendency toward higher prevalence of Mets among those with LBP than among those without it in women, but not in men.

A retrospective observational study. ⋯ The spinal changes with paravertebral ligament ossification in VDRR were described in this study. Four different gene mutations related to the PHEX gene were detected in them. The presence of these changes was suggestive of a more severe systemic disease.

Comparative Study
Adjacent-level range of motion and intradiscal pressure after posterior cervical decompression and fixation: an in vitro human cadaveric model.
This in vitro human cadaveric study measured adjacent-level kinematics after posterior cervical decompression and fixation. ⋯ For C3-C6 laminectomy, instrumentation to C7 significantly decreased flexion/extension ROM and intradiscal pressure at C6-C7 without significantly increasing either measure at C2-C3 or C7-T1 relative to C3-C6 fixation. In the setting of a C3-C7 laminectomy, when instrumenting to either C2 or T2, consideration should be given to including both levels within these constructs.

A retrospective data analysis. ⋯ VTE-related morbidity and mortality have heightened the awareness within the spine community to the perioperative management of patients undergoing major spinal reconstruction. Prophylactic IVC filter placement significantly lowers VTE-related events, including PE development, than population controls.
