Clinical TrialC2 pedicle screw and plate combined with C1 titanium cable fixation for the treatment of atlantoaxial instability not suitable for placement of C1 screw.
A method of atlantoaxial stabilization using individual fixation of the C1 posterior arch and the C2 pedicle with C2 pedicle screws and plates combined with C1 titanium cables is described. In addition, the clinical results of this method on 8 patients are described. ⋯ C2 pedicle screw and plate combined with C1 titanium cable could be used to treat atlantoaxial instability in the cases not suitable for placement of C1 screw.

Treatment of unstable lower cervical spine injuries by anterior instrumented fusion alone.
Retrospective study of a prospectively followed cohort. ⋯ Anterior instrumented fusion is at least as efficient as the posterior procedure in the management of cervical spine injuries and it also has several advantages. Most of such injuries, including the dislocations, can be managed with anterior instrumented fusion alone. Simple means of immobilization such as the hard collar suffice, and secondary posterior fixation is rarely, if ever, necessary.

Clinical TrialMinimally invasive multilevel percutaneous correction and fusion for adult lumbar degenerative scoliosis: a technique and feasibility study.
Prospective evaluation of 12 patients undergoing surgery for lumbar degenerative scoliosis. ⋯ A combination of 3 MIS techniques allows for correction of lumbar degenerative scoliosis. Multisegment correction can be performed with less blood loss and morbidity than for open correction.

Retrospective radiographic review. ⋯ The results of our study demonstrate that the patients with type II and shallow type III odontoid fractures do not require MRI screening for TAL injury. We found no cases of patients with late instability to suggest that a TAL injury was missed.

MR findings of exaggerated fluid in facet joints predicts instability.
Retrospective radiographic review. ⋯ Exaggerated fluid in the facets seen on axial MRI is significantly suggestive of spondylolisthesis on standing films, even if this is not appreciated on the supine sagittal MRI sequences. This is the first time that the relative incidence of subtle instability with and without this finding has been evaluated to our knowledge.
