A quantitative biomechanical analysis of mechanism of pain alteration in 4 cases of low back pain. ⋯ Immediate pain reduction can be achieved by altering muscle-activation and movement patterns. However, the combination for optimal success seems to be different for every individual. Pain provocation tests help to "tune" the intervention. This also suggests that patient-classification schemes may need more refinement to address this heterogeneity.

Multicenter Study Comparative Study
Antifibrinolytic agents reduce blood loss during pediatric vertebral column resection procedures.
Retrospective multicenter review. ⋯ EBL associated with VCR was highly variable and in many cases exceeded the patient's BV. AF agents were not routinely used and we had insufficient data to assess the efficacy of aminocaproic acid. Both aprotinin and TXA resulted in less EBL than when no AF was used; however, the effect of the reduction varied by site. Aprotinin has since been removed from the market. When normalized to patient size and levels excised, the use of TXA resulted in a reduction in intraoperative EBL.

Multicenter Study
Cervical spine trauma in diffuse idiopathic skeletal hyperostosis: injury characteristics and outcome with surgical treatment.
Retrospective study of a consecutive series of operatively managed patients with cervical fractures with diffuse idiopathic skeletal hyperostosis (DISH) presenting to 3 institutions over an 8 year period. ⋯ The current findings pinpoint the potential for medical and surgical complications in this high risk subgroup. Surgeons should be aware of the unique aspects associated with treatment of these injuries.

Controlled Clinical Trial
Teriparatide accelerates lumbar posterolateral fusion in women with postmenopausal osteoporosis: prospective study.
Prospective trial. ⋯ Daily subcutaneous injection of teriparatide for bone union using local bone grafting after instrumented lumbar posterolateral fusion in women with postmenopausal osteoporosis was more effective than oral administration of bisphosphonate.

Prospective study in a morbidly obese population after bariatric surgery. ⋯ Bariatric surgery, resulting in significant weight reduction, was associated with a significant decrease in low back and radicular pain as well as a marked increase in the L4-L5 intervertebral disc height. Reduction in body weight after bariatric surgery in morbidly obese patients is associated with a significant radiographical increase in the L4-L5 disc space height as well as a significant clinical improvement in axial back and radicular leg pain.
