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.

Case ReportsTranspedicular drainage of presacral abscess and posterior decompression of acute cauda equina syndrome in caries spine: a case series of 3 patients.
We describe 3 patients with lumbosacral tuberculosis with epidural and presacral abscess who presented to us with acute cauda equina syndrome. A novel technique of draining the abscess and its results are described. ⋯ The transpedicular approach to the presacral region is a safer option compared with other approaches to reach this region. It simultaneously allows decompression of cauda equina nerve roots by laminotomy without changing the position of the patient in the theater. The key to success with this approach is early diagnosis and early treatment.

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.

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.

Postoperative spinal epidural hematoma after microscopic lumbar decompression: a prospective magnetic resonance imaging study in 89 patients.
A prospective case series. ⋯ The incidence of postoperative SEH after microscopic lumbar decompressive surgery was 14.6%. Postoperative SEH did not delay clinical improvements. Age 50 years old or more was strongly associated with the development of postoperative SEH.
