Cross-sectional study. ⋯ Expenditures have increased over time in adults with SRDs. PS is significantly associated with expenditures after controlling for predisposing and enabling factors, but not significant after controlling for need factors. Need factors appear to explain the relationship between lower levels of PS and higher HCE in adults with SRDs.Level of Evidence: 2.

Micro-computed tomography- (micro-CT-) based finite element analysis of cadaveric human lumbar vertebrae virtually implanted with total disc arthroplasty (TDA) implants. ⋯ Typically-sized TDA implants disproportionately increase the bone-tissue stress in more porous vertebrae; this affect is accentuated when the implant impinges in sagittal bending.Level of Evidence: N/A.

Retrospective. ⋯ Patient BMI may not affect pain and disability outcomes in patients undergoing a multimodal rehabilitation treatment for chronic LBP. In contrast to BMI, other covariates such as age, treatment sessions, and pre-treatment NPRS and ODI scores may be associated with increased risk for poor treatment outcome. Obese individuals can expect clinical outcomes similar to normal or overweight individuals with multimodal physical rehabilitation for chronic LBP.Level of Evidence: 3.

Multicenter Study Observational Study
Pain During Sex Before and After Decompressive Surgery for Lumbar Spinal Stenosis: A Multicenter Observational Study.
Observational multicenter study. ⋯ This study clearly demonstrates that a large proportion of patients undergoing surgery for LSS experienced an improvement in pain during sexual activity at 1 year.Level of Evidence: 2.
