Epidural analgesia for postoperative pain control after adolescent spinal fusion procedures which violated the epidural space.
Retrospective chart review. ⋯ Overall, patients managed with an epidural had significantly lower pain scores than those managed with IV PCA despite violation of the epidural space.

Mesh cage reconstruction with autologous cancellous graft in anterior cervical discectomy and fusion.
Retrospective case series. ⋯ Autologous bone grafting with mesh cage reconstruction is an acceptable alternative to autologous tricortical structural graft or allograft with reduced donor site pain and excellent biologic arthrodesis.

Analysis of the relationship between facet joint angle orientation and lumbar spine canal diameter with respect to the kinematics of the lumbar spinal unit.
Retrospective cross-sectional study. ⋯ We demonstrated the relationship among facet orientation, osseous canal diameter, kinematics of a spinal unit, and change in lumbar spine canal diameter. Patients with sagittally oriented facets had narrow osseous canals with mobility, whereas those with coronally oriented facets had stable and wider osseous canals. This finding is helpful in understanding the mechanism underlying lumbar spinal canal stenosis and degenerative spondylolisthesis.

Randomized Controlled Trial Comparative StudyMicrodecompressive laminatomy with a 5-year follow-up period for severe lumbar spinal stenosis.
The 2 groups of patients with severe lumbar spinal stenosis were prospectively compared as a case control study. ⋯ Compared with classic approaches, bilateral MDL provides adequate and safe decompression in lumbar spinal stenosis. It significantly reduces clinical symptoms and disability. However, TL shows higher perioperative complications and postoperative instability. To the best of our knowledge, this is the first study to define a bilateral MDL approach to treat the stenotic lumbar spine without a herniated disc.

Radiostereometric analysis of postoperative motion after application of dynesys dynamic posterior stabilization system for treatment of degenerative spondylolisthesis.
Prospective case series ⋯ The Dynesys dynamic instrumentation system seems to stabilize degenerative spondylolisthesis. As expected in the degenerative lumbar spine, the segmental motion of the implanted level in this study was limited and considerably less than normal spinal motion.
