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.

A retrospective review of a consecutive population of patients treated with radiofrequency-targeted vertebral augmentation (RF-TVA) for malignant vertebral compression fractures (VCFs). ⋯ We report optimum safety and efficacy results in the treatment of malignant VCFs with a novel RF-TVA technique in which controlled delivery of an ultrahigh viscosity PMMA is used for fracture stabilization. The deposition of PMMA with RF-TVA is predictable and uniform, and can be performed without the PMMA handling constraints that may be encountered with vertebroplasty and balloon kyphoplasty. The safety and efficacy we report with RF-TVA achieved equivalency with other methods of treatment for VCF stabilization.

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.
