Comparative Study Observational Study
Do Markers of Inflammation and/or Muscle Regeneration in Lumbar Multifidus Muscle and Fat Differ between Individuals with Good or Poor Outcome Following Microdiscectomy for Lumbar Disc Herniation?
Observational study. ⋯ Results show a relationship between impaired muscle regeneration profile in multifidus muscle and poor outcome following microdiscectomy for LDH. Inflammatory dysregulation in subcutaneous fat overlying the back region might predict poor surgical outcome.Level of Evidence: 4.

Randomized Controlled Trial Multicenter Study
Predictive Factors Affecting Surgical Outcomes in Patients With Degenerative Lumbar Spondylolisthesis.
Post-hoc analysis of 5-year follow-up data from a prospective randomized multicenter trial. ⋯ While the degree of vertebral slippage and the presence of angulation were not associated with poor recovery after surgery for lumbar degenerative spondylolisthesis, postoperative outcomes were associated with the intervertebral angle and the presence of translation. Careful preoperative measurement of these factors may help to predict poor postoperative outcomes.Level of Evidence: 3.

Observational cross-sectional. ⋯ LTPA was inversely associated with the prevalence of LBP in adults from primary care. This association was influenced by sedentary behavior and BMI.Level of Evidence: 4.

Retrospective cohort. ⋯ Our 2-year postoperative MCID analysis is the first mental health calculation from an MIS TLIF cohort. We report a 2-year MCID value for PHQ-9 of 3.0 (2.0-4.8). MCID values for mental health instruments are important for determining overall success of lumbar spine surgery.Level of Evidence: 3.
