Retrospective study from data from a single access surgeon at 2 hospitals. ⋯ The high frequency of multiple ILVs found during the anterior approach is crucial knowledge for access surgeons, as it will help them anticipate such anomalies and thus avoid the potentially catastrophic complications of an avulsion of an unexpected extra vein.

Retrospective case control study. ⋯ Neuromuscular patients fused to the pelvis, children older than 11 years, and surgery duration greater than 6 hours were associated with positive cultures. Back acne is a preventable risk factor for P. acnes seeding. Intraoperative bacterial contamination indicates a need to consider the type of surgery and patient age to determine prophylactic antibiotics and other modalities to prevent infection.

Multicenter Study
Variation in outcomes across centers after surgery for lumbar stenosis and degenerative spondylolisthesis in the spine patient outcomes research trial.
Retrospective review of a prospectively collected database. ⋯ There is a broad and statistically significant variation in short- and long-term outcomes after surgery for SPS and DS across various academic centers, when statistically significant baseline differences are adjusted for. The findings suggest that the choice of center affects outcome after these procedures, although further studies are required to investigate which center characteristics are most important.

Randomized Controlled Trial Comparative Study
Adding chiropractic manipulative therapy to standard medical care for patients with acute low back pain: results of a pragmatic randomized comparative effectiveness study.
Randomized controlled trial. ⋯ The results of this trial suggest that CMT in conjunction with SMC offers a significant advantage for decreasing pain and improving physical functioning when compared with only standard care, for men and women between 18 and 35 years of age with acute LBP.

Multicenter Study Clinical Trial
Next generation of growth-sparing techniques: preliminary clinical results of a magnetically controlled growing rod in 14 patients with early-onset scoliosis.
Prospective nonrandomized study. ⋯ Preliminary results indicated MCGR was safe and provided adequate distraction similar to standard GR. DR achieved better initial curve correction and greater spinal height during distraction compared with SR. No major complications were observed during the follow-up.
