Diffusion tensor (DT) imaging-based fiber tracking is a noninvasive magnetic resonance technique that can delineate the course of white matter fibers. ⋯ DT imaging-based fiber tracking is a reliable and accurate method for mapping the course of subcortical PTs. Fiber tracking and intraoperative MEPs were useful for preserving motor function in patients with gliomas near the PT.

Randomized Controlled Trial
Evaluation of epidural analgesic paste components in lumbar decompressive surgery: a randomized double-blind controlled trial.
Adjuncts for pain management in lumbar decompressive surgery are needed to reduce narcotic consumption and promote early mobility. ⋯ An analgesic paste containing methylprednisolone acetate is effective at reducing postoperative pain after lumbar decompressive surgery. Mixing effective doses of morphine sulfate in the paste abrogates the expected analgesic effects of epidural morphine.

Outcome of lumbar disc herniation is often based on clinical scores and less frequently on the neurological examination. However, even when clinical outcome measures are favorable, patients may still experience motor or sensory impairment. ⋯ There seems to be no correlation between clinical results and neurological impairment when assessed by the VAS and ODI.
