To assess diffusion tensor imaging (DTI) parameters in cervical compressive myelopathy (CCM) patients compared to normal volunteers, to relate them with myelopathy severity, and to relate tractography patterns with postoperative neurologic improvement. ⋯ DTI parameters in CCM patients were significantly different from those in normal volunteers but were not significantly related to myelopathy severity. The patterns of tractography appear to correlate with postoperative neurologic improvement.

Evaluate the efficacy of percutaneous vertebroplasty for severe vertebral body compression fractures. ⋯ Percutaneous vertebroplasty is safe and effective in the treatment of single level severe vertebral body compression fractures.

To describe an "indirect" cervical nerve root injection technique with a dorsal approach that should carry less inherent risk than the "direct" cervical transforaminal injection approach, and to compare the immediate post-injection results of the two procedures. ⋯ The indirect cervical nerve root injection procedure is a potentially safer alternative to direct cervical transforaminal nerve root injections. The short-term pain reduction is similar using the two injection methods.

The purpose of this study was to evaluate the incidence and risk factors associated with adjacent vertebral fracture after percutaneous vertebroplasty (PVP) to treat osteoporotic vertebral compression fractures. We also investigated the effect of intradiscal cement leakage on adjacent vertebral fracture formation after PVP. ⋯ Intradiscal cement leakage does not seem to be related to subsequent adjacent vertebral compression fracture in patients who underwent PVP for treatment of an osteoporotic compression fracture. The thoracolumbar location of the initial compression fracture is the only factor correlated with an adjacent vertebral fracture after PVP.
