A retrospective review of children with neuromuscular scoliosis treated at our institution with posterior spinal fusion and instrumentation including iliac screws. ⋯ The use of screw fixation in the ilium as a means of spinopelvic anchorage is safe and effective in the treatment of neuromuscular scoliosis. The use of 2 screws in each iliac wing provides more stable fixation with fewer implant-related complications than using a single screw.

Using a retrograde neurotracing method with Fluoro-Gold (FG), the level at which dorsal root ganglions (DRGs) innervate the L2 and L5 vertebral bodies and the innervation pathways were investigated in rats. ⋯ Sensory nerve fibers in the L2 and L5 vertebral bodies are derived from the T11-L3 and T13-L6 DRGs, respectively. Some sensory nerves from the L2 and L5 vertebral bodies enter the paravertebral sympathetic trunks and reach the DRGs at multisegmental levels. The present findings regarding multisegmental innervation to vertebral bodies may explain the diffuse pain that originates within osteoporotic vertebral fractures in elderly patients.

Cross-cultural adaptation and cross-sectional psychometric testing. ⋯ The Moroccan version of the RMDQ has good comprehensibility internal consistency, reliability, and validity for the evaluation of Moroccan-speaking patients with LBP.

A prospective single-cohort study of 31 patients surgically treated for pelvic injuries with displaced sacral fractures. ⋯ Although the majority of patients achieved independent living, medium-term follow-up indicated significant residual disability. The complex nature of these fractures and the associated injuries should be considered in the rehabilitation of these patients.

Comparative Study
Biomechanical in vitro testing of human osteoporotic lumbar vertebrae following prophylactic kyphoplasty with different candidate materials.
Biomechanical study of human osteoporotic lumbar vertebrae following prophylactic kyphoplasty. ⋯ This study demonstrated that calcium phosphate cements displayed identical behavior to PMMA cement with respect to in vitro mechanical qualities. Consequently, from a mechanical viewpoint, calcium phosphate cements may be used in addition to PMMA cement for kyphoplasty and prophylactic kyphoplasty. Silicon derivatives are apparently not recommendable as candidate materials for kyphoplasty.
