Differentiating osteoporotic vertebral fractures (OVFs) from metastatic vertebral fractures (MVFs) is an important clinical challenge. A novel magnetic resonance imaging (MRI)-based score (the META score) was described, aiming to differentiate OVF from MVF. This score showed an almost perfect agreement by the group developing it, but an independent agreement evaluation is pending. ⋯ The interobserver agreement using the META score was adequate for spine surgeons but not for other potential users (radiologists); the intraobserver agreement was poor. Further studies are thus necessary before the use of this score is recommended.

As health-care transitions to value-based models, there has been an increased focus on patient factors that can influence peri- and postoperative adverse events, resource use, and costs. Many studies have reported risk factors for systemic complications after cervical fusion, but none have studied chronic opioid therapy (COT) as a risk factor. ⋯ Preoperative opioid use among patients who underwent cervical fusion increases complication rates, postoperative opioid usage, health-care resource use, and costs. These risks may be reduced by restricting the duration of preoperative opioid use or weaning off before surgery. Better understanding and management of pain in the preoperative period with judicious use of opioids is critical to enhance outcomes after cervical fusion surgery.

The prevalence of dialysis-dependent patients in the United States is growing. Prior studies evaluating the risk of perioperative adverse events for dialysis-dependent patients are either institutional cohort studies limited by patient numbers or administrative database studies limited to inpatient data. ⋯ Dialysis patients undergoing elective spine surgery are at significantly higher risk of aggregated adverse outcomes, return to the operating room, readmission, and death than non-dialysis patients, even after controlling for patient demographics and overall health (as indicated by ASA class). These differences need to be considered when determining treatment options. Additionally, with bundled payments expected in spine surgery, physicians and hospitals need to account for increased costs and liabilities when working with dialysis patients.

Observational Study
Stand-alone lateral lumbar interbody fusion for the treatment of symptomatic adjacent segment degeneration following previous lumbar fusion.
Revision posterior decompression and fusion surgery for patients with symptomatic adjacent segment degeneration (ASD) is associated with significant morbidity and is technically challenging. The use of a stand-alone lateral lumbar interbody fusion (LLIF) in patients with symptomatic ASD may prevent many of the complications associated with revision posterior surgery. ⋯ Stand-alone LLIF is a safe and effective approach with low morbidity and acceptable complication rates for patients with symptomatic ASD following a previous lumbar fusion.

Observational Study
The influence of hand grip strength on surgical outcomes after surgery for degenerative lumbar spinal stenosis: a preliminary result.
Although a number of prognostic factors have been demonstrated to be associated with surgical outcome of degenerative lumbar spinal stenosis (DLSS), no study has investigated the relation between hand grip strength (HGS) and treatment outcome of DLSS. ⋯ Patients with preoperative high HGS display better surgical outcome in terms of disability and health status 6 months after spine surgery. Preoperative HGS can act as a predictor of surgical outcome in patients with DLSS.
