Chronic pain and obesity are both on the rise. Spinal cord stimulation has gained increasing popularity in the pain management field for the treatment of spine-related chronic pain, however to-date, the correlation between the spinal cord stimulator effectiveness and increasing body mass index (BMI) has not been fully established. ⋯ A negative association between SCS effectiveness and increasing BMI was found, whereas, no significant difference was noted amongst the various BMI cohorts and the daily opioid consumption.

Observational Study
Spinal epidural lipomatosis is a previously unrecognized manifestation of metabolic syndrome.
Spinal epidural lipomatosis (SEL) is a condition in which excess lumbar epidural fat (EF) deposition often leads to compression of the cauda equina or nerve root. Although SEL is often observed in obese adults, no systematic research investigating the potential association between SEL and metabolic syndrome has been conducted. ⋯ This is the first study to demonstrate that metabolic syndrome is associated with SEL in a relatively large, unbiased population. Our data suggest that metabolic-related conditions are potentially related to EF deposition and that SEL could be a previously unrecognized manifestation of metabolic syndrome.

The cartilaginous and bony material that can be present in herniated tissue suggests that failure can involve both cartilaginous and vertebral-endplates. How structural integration is achieved across the junction between these two distinct tissue regions via its fibril and mineral components is clearly relevant to the modes of endplate failure that occur. ⋯ This study provides clear evidence of structural connectivity across the cartilaginous-vertebral endplate junction by the intermingling of their fibrillar components and mediated by the mineral phase. This is consistent with the clinical observation that in some disc herniations bony material can be still attached to the extruded soft tissue.

Comparative Study
Percutaneous radiofrequency ablation versus open surgical resection for spinal osteoid osteoma.
Both open surgical resection (OSR) and radiofrequency ablation (RFA) have been reported for spinal osteoid osteoma (OO). ⋯ If there is sufficient cerebrospinal fluid between the spinal OO lesion and spinal cord/nerve root (more than 1 mm), RFA is effective and safe for treatment of well-selected spinal OO, showing reduced operating time, blood loss, in-hospital stay, and complications compared to OSR. However, OSR is still recommended in cases with spinal cord/nerve root compression.

Osteoporosis remains an underrecognized and undertreated disease entity in the orthopaedic setting, accounting for substantial long-term morbidity and mortality. Osteoporosis is often not diagnosed or treated until multiple fractures have occurred. Vertebral compression fractures are the most common sentinel fracture, providing an opportunity to intervene with antiresorptive therapy before more debilitating fractures occur. Little data has been published on osteoporosis screening and treatment following vertebral fractures. Further elucidation of the osteoporosis care gap in these patients is warranted. ⋯ In the absence of a specific local program to improve secondary fracture prevention following minimal trauma spinal fractures, recognition and treatment of osteoporosis in patients at this institution remained dismal over time despite numerous calls to action on the topic in the orthopaedic literature and elsewhere. Undertreatment of osteoporosis puts patients at increased risk of incurring additional fractures. Within 2 years, 38% of the patients in this sample developed an additional fragility fracture. This study demonstrates a profound post vertebral fracture osteoporosis care gap.
