All patients aged 80 years or older, treated surgically for lumbar spine disorders from 1996 to 2001, were analyzed in a retrospective case series. The purpose of this study was to determine if higher than expected morbidity and mortality was observed for patients undergoing lumbar spine surgery in their ninth decade of life, and if any preoperative factors correlated with this outcome. ⋯ The negative effect of age on surgical morbidity and mortality has been established. However, the effect of comorbidity has not been linked to the occurrence of major complications. Comorbidity may predict major complications. Choosing patients with less preoperative comorbidity will help to minimize complications.

Retrospective single-center consecutive case series with two [corrected] year follow-up. ⋯ Kyphoplasty markedly improves clinical outcome [corrected] and results in significant vertebral height restoration and normalization of morphologic shape indices [corrected] that remain stable for at least two [corrected] years following treatment.

A case report. ⋯ It must be kept in mind that cervical spine surgery is not an exceptional precipitator of cervical dystonia, despite the fact that it is extremely rare.

Seventeen healthy volunteers were subjected to right and left lateral impacts 5.0, 6.8, 9.2, and 16.8 m/s acceleration while positioned in a Volvo car seat with lap and shoulder seat belt restraint in laboratory setting. ⋯ Compared with previously reported impact studies with a 5-point harness and rigid seat, the use of a 3-point lap and shoulder seat belt with car seat does not appear to adversely affect the cervical muscle response. In very-low- and low-velocity impact experiments, seat belt and seat type may thus not be particularly relevant to cervical EMG and kinematics.

A reliability study was conducted. ⋯ The ossification-kyphosis angle in the sagittal view of MRI has potential as an indicator of the effectiveness of posterior decompression in this disease. It is thought that there is a critical point of posterior decompression at nearly 23 degrees of the ossification-kyphosis angle of the decompression site. When the ossification-kyphosis angle is more than 20 degrees , the presence of echo free space should be carefully confirmed in intraoperative ultrasonography.
