An in vitro biomechanical study of 3 lumbosacral fixation techniques in human cadaveric lumbar-pelvic spine models. ⋯ The 4-rod technique achieved stable biomechanical effects in lumbosacral fixation. At the L5-S1 junction, the 4-rod technique demonstrated better stability than the constructs using S1 screws or S1 screws plus iliac screws..

Prospective cohort study. ⋯ This study found that being older, having lower fitness scores, wearing armor longer, and wearing heavier loads increased the risk of LBP in deployed soldiers. Units more likely to wear loads such as the Infantry and Cavalry and tasks commonly involving wearing loads such as patrolling all increased the risk of LBP as well.

Retrospective institutional database review. ⋯ Preoperative in-room time prior to the start of surgical incision is an independent risk factor for SSI. All possible steps should be taken prior to entry into the operating theater to reduce in-room time and opening of surgical sterile instrumentation be delayed until the surgery is ready to proceed.

Randomized Controlled Trial Multicenter Study Comparative Study
A prospective, randomized, controlled clinical investigation comparing PCM cervical disc arthroplasty with anterior cervical discectomy and fusion. 2-year results from the US FDA IDE clinical trial.
Prospective, multicenter, randomized Food and Drug Administration approved investigational device exemption clinical trial. ⋯ The treatment of symptomatic single-level cervical spondylosis with PCM achieves clinical outcomes that are at least equivalent to ACDF while maintaining motion. At 2 years, patients with PCM had lower NDI scores, statistically lower rate of prolonged dysphagia, greater patient satisfaction, and superior overall success.
