Case ReportsFoot drop caused by a lesion in the thoracolumbar spine.
Fifteen patients with foot drop caused by a thoracolumbar spine lesion were retrospectively investigated. ⋯ Prognosis of foot drop was much better when the causative lesion was at the thoracolumbar spine than when it was at the lumbar spine. Severe paralysis was not a poor prognostic factor.

The results of vascularized-free fibular grafts in complex spinal reconstruction.
Retrospective review. ⋯ Vascularized-free fibular grafts are effective in the treatment of complex spinal reconstruction after surgery for spinal tumors or osteomyelitis. The vascularized-free fibular graft adds structural support as well as living bone to the fusion site and is a reasonable alternative to nonvascularized grafts in locally compromised surgical beds.

Randomized Controlled Trial Comparative StudyBiomechanical comparison of odontoid plate fixation versus odontoid screw fixation.
Randomized controlled trial with statistically significant difference or statistically no significant difference (Level I). ⋯ Plate fixation of the odontoid process for certain type II odontoid fracture patterns provided a significantly higher biomechanical stability than the technique of odontoid screw fixation. Using a specially designed plate construct fixed with 2 cancellous screws into the body of C2 and an additional cortical screw inserted in the odontoid process, 84% of the original stability of the intact odontoid was restored. Single- or double-screw fixation of the odontoid only restored approximately 50% of the original strength.

Long-term follow-up of revision decompressive lumbar spinal surgery in elderly patients.
A retrospective study of elderly patients (more than 65 y of age) who underwent surgery for lumbar spinal stenosis between 1990 and 2000 was carried out. Among all these patients, the patients who underwent revision surgery were studied. ⋯ Even in reoperated elderly patients with spinal stenosis without spinal fusion, an improvement in functional status and somewhat in pain perception can be anticipated.

Trajectory of transsacral iliac screw for lumbopelvic fixation: a 3-dimensional computed tomography study.
A 3-dimensional multi detector computed tomography study. ⋯ The TSIS could be safely inserted without increasing the general risk of conventional iliac screw. On the basis of the result of this study, we consider the TSIS technique a useful option for lumbopelvic fixation to overcome disadvantages of iliac screw.
