Investigations of the effects of high bone turnover on the L3 vertebra were carried out, using an ovariectomized (OVX) ovine model of early stage osteoporosis. ⋯ These findings show that OVX resulted in changes in bone turnover, which reduced biomechanical properties in a model of early stage osteoporosis. These differences were present despite microarchitecture or BMD remaining unchanged. In the future, the ability to assess site-specific bone turnover would greatly enhance the accuracy with which fracture risk could be predicted.

We developed a real-time, in vivo monitoring system for the evaluation of spinal cord viability in rats during spinal cord ischemia. ⋯ The monitoring of the mitochondrial function together with SCBF by the TVMS reflects the viability of the spinal cord tissue and, together with the conventional monitoring techniques, may help to evaluate the spine conditions, especially under surgical procedures involving the deterioration of the spinal cord blood supply.

A systematic review of randomized controlled trials (RCTs). ⋯ Acupuncture versus no treatment, and as an adjunct to conventional care, should be advocated in the European Guidelines for the treatment of chronic LBP.

Reconstruction of large iliac crest defects after graft harvest using autogenous rib graft: a prospective controlled study.
Prospective controlled study analyzing the donor site morbidity after reconstruction of full thickness iliac crest defects, using autologous rib grafts. ⋯ Rib graft reconstruction provides a cheap and effective alternative for iliac crest reconstruction. Patients undergoing thoracotomy or thoraco-phrenico-lumbotomy for spinal reconstruction, the unutilized rib graft should be used to reconstruct the iliac defect. Reduced donor site morbidity and better cosmesis are the major benefits of reconstruction.

Retrospective review of adolescent idiopathic scoliosis (AIS) patients. ⋯ Two Lenke 1A curve patterns can be described based on the direction of the L4 tilt. This distinction has ramifications regarding selection of fusion levels and assessing surgical outcomes. The A and B lumbar modifiers do not describe 2 distinct curve types within the Lenke 1 group; however, the tilt direction of L4 does allow subdivision of the Lenke 1A curves into 2 distinguishable patterns (1A-R and 1A-L). The 1A-L curves are similar to 1B curves and different in form and treatment from the 1A-R pattern.
