Spine
-
Prospective study. ⋯ ROM of the cervical spine decreased by 30.5% after laminoplasty. Kyphosis was developed in 10.6% of the patients. The preoperative factors affecting postoperative kyphosis are diagnosis of myelopathy cases associated with cervical spondylosis, a lordosis angle of <10 degrees, and a kyphotic angle during flexion that is larger than a lordotic angle during extension.

Prospective observational cohort study. ⋯ The critical degree of spinal cord compression needed to induce clinically significant signs was found between 50 and 60 mm2 of cross-sectional transverse area at the level of maximal compression in association with MRI hyperintensities.

A case report. ⋯ Although technically demanding, C1-C2 transpedicular screw fixation combined with interspinous bone graft wiring after open reduction may be an alternative treatment option if conservative treatment fails to reduce AARF.

Pedicle screw fixation (PSF) has been used for the setting of a lumbar interbody fusion. ⋯ Geometric constraints caused by PSF will reduce substantially the bone stress level and the relative motion, and therefore be more likely to allow bone ingrowth at the bone-cage interface, compared with the stand-alone ALIF. The use of pedicle screw stabilization would have significant beneficial effects on the rate of interbody fusion, regardless of whether ALIF or PLIF was used.
