Comparative Study
Biomechanical analysis comparing three C1-C2 transarticular screw salvaging fixation techniques.
This is an in vitro biomechanical study. ⋯ Fixation of atlantoaxial complex using unilateral transarticular screw supplemented with contralateral C1 lateral mass and C2 intralaminar screws is biomechanically equivalent to C1 lateral mass and C2 pedicle screws and both are biomechanically superior to C1-C2 sublaminar wire in axial rotation.

Observational prospective study. ⋯ This first Spanish version of the Neck Disability Index is reliable, valid, and sensitive to change.
-
Laboratory investigation, ex vivo. ⋯ The low degree of heating and minor artifacts associated with the Resolve-based cervical external immobilization devices indicated that these products are safe for patients undergoing MRI at 3-Tesla.
-
Case report. ⋯ We present the first report describing a case of anterior spinal cord syndrome caused by a cement embolism in the anterior spinal artery after vertebroplasty. The severity of this complication warrants that surgeons should inform patients of the same while obtaining their consent for vertebroplasty.

Pre-post intervention study using outcome measure design. ⋯ Vertebral wedge osteotomy is potentially an effective treatment option for paralytic scoliosis. At 2-year follow-up, there was no loss of function as measured by the PODCI and FIM, and there was improvement in the COPM. Cobb angle measurements were either improved or maintained in 12 of 13 patients. Although 2 patients required fusion, they had an average of 2.5 years of subsequent growth before surgery.
