A retrospective imaging study of 73 patients who underwent surgery for cervical spondylotic myelopathy (CSM) between April 2005 and July 2007. ⋯ Patients with low SI ratio who were not too old and had a shorter duration of disease experienced a good surgical outcome. However, with the increase of SI ratio and the occurrence of pyramidal sign, a poor prognosis after surgery will show. SI ratio and clinical manifestation can be a predictor of surgical outcome.

Retrospective review. ⋯ C-arm CBCT with needle path overlay for fluoroscopic guided vertebroplasty is feasible and allows for reliable unilateral therapy of both lumbar and thoracic vertebral bodies. Extrapedicular approaches were performed safely and with good accuracy of reaching the targets.

Spinal fusion for spastic neuromuscular scoliosis: is anterior releasing necessary when intraoperative halo-femoral traction is used?
Retrospective radiographic and clinical study. ⋯ When intraoperative halo-femoral traction is used, PSF-only surgery for NMS can provide excellent curve correction and spinal balance. In this study, the PSF-only group had shorter OR time, lower EBL, lower frequency of postoperative intubation, and fewer cases of pneumonias when compared with A/PSF with similar radiographic outcomes at 2-year follow-up.

A case report of traumatic atlantooccipital dislocation (AOD) managed by intraarticular-posterior fusion from a posterior approach at the C0-C1 level with preservation of C1-C2 motion. ⋯ Intraarticular and posterior fusion of the atlantooccipital joint was able to provide an excellent long-term clinical outcome in the treatment of traumatic AOD in a child. This is the first report of an intraarticular fusion of the C0-C1 segment and the longest follow-up published on isolated C0-C1 stabilization.

An in vitro biomechanical study of the effectiveness of halo-vest fixation. ⋯ The present results, which document snaking motion of the cervical spine due to the halo-vest, indicate that an inadequately fitting or loose vest may significantly diminish its immobilization capacity leading to delayed healing or nonunion.
