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.

The relationship of intrapsoas nerves during a transpsoas approach to the lumbar spine: anatomic study.
A cadaveric study. ⋯ This study suggests that the intrapsoas nerves are a safe distance from the radiographic center of the intervertebral disc in a majority of cases; however, anatomic variations in the location of these nerves place them at injury risk in a small number of cases. These results suggest that neural monitoring whereas traversing the psoas may be important to enhance the safety of the transpsoas approach. Care is particularly warranted at the L4-5 level.

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.

Implant removal for the management of infection after instrumented spinal fusion.
We operated on 21 patients with a postoperative deep wound infection. All the patients underwent implant removal and wide debridement. One patient lost to follow-up was excluded. ⋯ Our results indicate that implant removal and wide debridement for postoperative infection after posterior instrumented spine fusion can provide satisfactory results and could be one treatment option. However, the collapse of the disc space, loss of normal lordosis, and pseudoarthrosis are inevitable in patients with early postoperative infection.
