Changes of upper thoracic curve and shoulder balance in thoracic adolescent idiopathic scoliosis treated by anterior selective thoracic fusion using VATS.
A retrospective radiographic analysis. ⋯ Among patients who have DT curve, patients with mild left shoulder elevation (<20 mm) can be treated by anterior correction unless the magnitude of upper thoracic curve or superior portion of lower thoracic curve are ≥30 degrees. For anterior correction, criteria of DT curve might be applied less strictly.

The facet joint loading profile of a cervical intervertebral disc replacement incorporating a novel saddle-shaped articulation.
Biomechanical study. ⋯ Biomechanical testing in an ovine model demonstrated no significant difference in measured facet pressures and forces between an intact native cervical disc specimen and a cervical intervertebral disc prosthesis using a saddle-shaped articulation. Peak and mean pressures were not demonstrated to be significantly different between the implanted and intact disc conditions. Implantation of the prosthesis resulted in a significant reduction of contact area under extension moments.

Comparative StudyIs there a difference between simultaneous or staged decompressions for combined cervical and lumbar stenosis?
We evaluated 43 patients diagnosed with tandem spinal stenosis (TSS) from 1999 to 2005 in an academic hospital. ⋯ These results indicate that TSS can be effectively managed by either surgical intervention, simultaneous, or staged decompressions. However, patient age, blood loss, and operative time do significantly impact outcomes. Therefore, operative management should be tailored to the patient's age and the option which will limit blood loss and operative time, whether that is by simultaneous or staged procedures.

Multilevel lumbar spinal stenosis decompression: midterm outcome using a modified hinge osteotomy technique.
A prospective cohort study was carried out looking at the functional outcome and post procedure translational segmental instability after multi-level lumbar decompression using a hinge osteotomy technique. ⋯ Decompression of multi-level lumbar spine stenosis using the unilateral approach with the hinge osteotomy technique is a safe approach for multi-level stenosis, with good outcome and no evidence of significant segmental translational spinal instability.

Extreme lateral interbody fusion approach for isolated thoracic and thoracolumbar spine diseases: initial clinical experience and early outcomes.
Retrospective review of prospective collected data on 22 patients. ⋯ The XLIF technique can be expanded to treat diseases in the thoracic spine. Although the magnitude of deformity correction achieved is less than that of the traditional open approaches, the lesser invasiveness of this technique may be tolerable for the elderly and in patients with significant medical comorbidities.
