Prospective cohort study. ⋯ One-third of initial bone grafts were found to be resorbed over 5 years and the majority of this resorption was found to occur between 6 months and 1 year after instrumented lumbar/lumbosacral fusion. Furthermore, bone graft volumetric changes were not affected by fusion methods or ranges of fusion, and did not affect clinical or functional outcomes. Although bone graft volume loss was found to increase with initial graft volume, larger bone grafts were found to result in a larger fusion mass.

Systematic Review. ⋯ Massage might be beneficial for patients with subacute and chronic nonspecific low back pain, especially when combined with exercises and education. The evidence suggests that acupuncture massage is more effective than classic massage, but this need confirmation. More studies are needed to confirm these conclusions, to assess the impact of massage on return-to-work, and to determine cost-effectiveness of massage as an intervention for low back pain.

Retrospective review of a prospective, multicenter study. ⋯ Despite having started with significantly greater leg pain and disability, surgically treated patients at 2-year follow-up had significantly less leg pain and disability than nonoperatively treated patients. Surgical treatment has the potential to provide significant improvement of leg pain in adults with scoliosis.

Comparison of feasibility and safety of the placement of short and long iliac screws by anatomic and biomechanical evaluations as they apply to lumbo-iliac fixation construct. ⋯ The local stability is rather difficult to be restored to the original levels regardless the length of iliac screws. Obviously, long iliac screws resisted significantly greater axial pullout force. However, under physiologic, torsional, and compressive loading conditions, the mechanical stability of lumbo-pelvic fixation construct with short iliac screws was comparable with that of the long ones. Therefore, the use of short iliac screws, which are only about half the length of the long iliac screws, could reduce the implantation risk without significantly compromising on the stability of the construct.

A comparative measurement design investigating the C4-Th1 intervertebral foramen under simulated clinical tests for cervical radiculopathy using magnetic resonance imaging. ⋯ During 3 clinical tests for cervical radiculopathy functional, relevant, and changes in the cervical intervertebral foramen were evident particularly in the middle cervical spine.
