Postoperative spinal implant infection (PSII) places patients at risk for pseudarthrosis, correction loss, spondylodiscitis, adverse neurological sequelae, and even death; however, prognostic factors that predict long-term treatment outcomes have not been clearly investigated. In addition, few studies concerning the feasibility of reconstructing the failed spinal events have been published. ⋯ Retention of the mechanically sound implants in early-onset infection permits fusion to occur, while delayed treatment, severe malnutrition and multiple comorbidities will most likely result in a lack of effectiveness in eradicating the infecting pathogens. Restoring optimal physiological conditions is imperative in high-risk patients to allow for further healing. When loosened screws cause peridiscal erosion and incapacitating motion pain, premature implant removal possibly results in failed fusion and correction loss. Reconstruction for a failed spinal event is feasible following infection control.

Randomized Controlled Trial Comparative Study
Documenting female spine motion during coitus with a commentary on the implications for the low back pain patient.
To describe female lumbar spine motion and posture characteristics during coitus and compare these characteristics across five common coital positions. Exacerbation of low back pain during coital movements and positions is a prevalent issue reported by female low back pain (LBP) patients. To address this problem, the first study to examine lumbar spine biomechanics during coitus was conducted. ⋯ The findings provided here may guide the clinician's specific recommendations, including alternative coital positions and/or movement patterns or suggesting a lumbar support, depending on the female LBP patient's specific motion and posture intolerances.

To evaluate the clinical and radiographic outcomes of posterior vertebral column resection (PVCR) and intraoperative manual traction to correct severe post-tubercular spinal deformity incurred during childhood. ⋯ PVCR and intraoperative manual traction are effective alternatives to manage severe post-tubercular spinal deformity although the procedure can be highly challenging with possible neurologic complications.

Observational Study
The effect of daily walking steps on preventing neck and low back pain in sedentary workers: a 1-year prospective cohort study.
This study aimed to investigate the causal relationship between daily walking steps and the 1-year incidence of neck and low back pain in workers with sedentary jobs. ⋯ Increasing daily walking steps is a protective factor for onset of neck pain in those with sedentary jobs. Interventions to reduce neck pain should include attempts to increase daily walking steps.

The purpose of this study was to investigate the impact of low back pain (LBP) on future health-related quality of life (HRQoL). Current evidence suggests that individuals with LBP have poorer HRQoL than those without LBP. However, most of the evidence comes from cross-sectional studies where LBP and HRQoL are determined at the same time. One prospective study examined the association between days with LBP and HRQoL but did not account for the intensity of LBP. Therefore, this association needs to be tested in a large prospective population-based sample with a valid measure of LBP and adequate control of known confounders. ⋯ Low back pain has an impact on future physical HRQoL. Strategies for reducing the effects of LBP on HRQoL should be an important focus for clinicians, researchers, and health policy makers.
