Retrospective database review. ⋯ Decompressive procedures performed later in the day carry a higher risk for postoperative infection. No similar trend was shown for fusion procedures. Our results identify potential modifiable risk factors contributing to infection rates in spinal procedures. Specific risk factors, although not defined in this study, might be related to contamination of the operating room, cross-contamination between health care providers during the course of the day, use of flash sterilization, and mid-day shift changes.

Randomized Controlled Trial Multicenter Study
Feasibility of using short message service to collect pain outcomes in a low back pain clinical trial.
Observational study nested within a randomized controlled trial. ⋯ SMS supplemented with phone interviews, but not SMS alone, is a feasible option to collect simple data within a back pain clinical trial setting.

Multicenter Study
The association of patient characteristics and spinal curve parameters with Lenke classification types.
Retrospective review. ⋯ Lenke types vary by sex, frequency magnitude, patient age, and patient self-image, which should be considered in designing studies.

Randomized Controlled Trial
Effect of core stability exercises on feed-forward activation of deep abdominal muscles in chronic low back pain: a randomized controlled trial.
A randomized controlled trial. ⋯ Abdominal muscle onset was largely unaffected by 8 weeks of exercises in chronic LBP patients. There was no association between change in onset and LBP. Large individual variations in activation pattern of the deep abdominal muscles may justify exploration of differential effects in subgroups of LBP.
