Yearly incidence of surgery for symptomatic lumbar disc herniation varies and is 29/100,000 in Sweden, 46/100,000 in Denmark and 58/100,000 in Norway. This variation was used to study whether differences in surgical incidence were associated with differences in preoperative patient characteristics as well as patient-reported outcomes. ⋯ We found no clear association between incidence of surgery for lumbar disc herniation and preoperative patient characteristics as well as outcome, and the differences between the countries were lower than the minimal clinical important difference in all outcomes.

Randomized Controlled Trial
Probiotics for chronic low back pain with type 1 Modic changes: a randomized double-blind, placebo-controlled trial with 1-year follow-up using Lactobacillus Rhamnosis GG.
To investigate whether treatment by lactic acid bacteria for 100 days is associated with change of disability and pain in chronic low back pain (CLBP) patients with type 1 or mixed Modic changes (MC) during 1-year follow-up. ⋯ No differences were found regarding the predefined outcomes. Overall, there was little improvement during the 1-year observation period. A small, though hardly clinically relevant, effect on back pain was seen after treatment by Lactobacillus Rhamnosis GG, and the treatment was without side effects in comparison with the control group.

Randomized Controlled Trial
Ultrasound-guided transforaminal percutaneous endoscopic lumbar discectomy: a new guidance method that reduces radiation doses.
The purpose of this study is to establish a new method to reduce the radiation dose during puncture and cannulation in percutaneous endoscopic lumbar discectomy (PELD). ⋯ US guidance is a new method that reduces the radiation dose required during puncture and cannulation in PELD.

Retrospective cohort study. ⋯ Pedicle screw constructs permit effective posterior-only correction of TK/TLK that is maintained at the 5-year follow-up time point. Patients report improvement, via outcome questionnaires, at the same follow-up time points. These slides can be retrieved under Electronic Supplementary Material.
