A radiographic study in 22 patients using magnetic resonance imaging was conducted. ⋯ The findings from this magnetic resonance imaging study suggest that the degree of semispinalis cervics repair affects postoperative cervical alignment, and significant loss of cervical lordosis tends to occur in elderly women who undergo laminoplasty.

Case Reports
Transpedicular eggshell osteotomies for congenital scoliosis using frameless stereotactic guidance.
Three cases of multiplanar congenital scoliosis corrected by a transpedicular eggshell osteotomy using frameless stereotactic guidance are reported. ⋯ One-stage posterior reduction eggshell osteotomy can be used to correct a sagittal and/or coronal congenital spinal curve imbalance. Frameless stereotactic guidance for solid pedicle screw fixation was essential to the achievement of rigid spinal stabilization before arthrodesis. Transpedicular eggshell osteotomy is a technique that should be considered for older patients who have congenital scoliosis with multiplanar spinal abnormalities.

An experimental study was conducted to evaluate the effects of lidocaine on nucleus pulposus-induced pathophysiologic changes. ⋯ The data indicate that lidocaine reduces the pathophysiologic changes in the dorsal root ganglion and hind paws induced by nucleus pulposus. These effects of lidocaine may relate to the mechanisms underlying the therapeutic effects of nerve root infiltration.

Case report of severe scoliosis and associated pelvic obliquity in a 14-year-old patient with cerebral palsy. ⋯ It is concluded that scoliosis with associated severe pelvic obliquity deformities can be treated with anterior and posterior spinal fusion and instrumentation with intraoperative halo-femoral traction in the properly selected and prepared patient with cerebral palsy.

Systematic review of prognostic studies of acute whiplash. ⋯ Scant knowledge about the prognosis of whiplash has been gained since the release of the Quebec Task Force report. However, it is becoming obvious that the insurance and compensation systems have a large impact on recovery from acute whiplash injuries. The conceptual framework used in this study demonstrates that large cohort studies investigating a wide range of prognostic factors are necessary to improve the understanding of this problem.
