Multicenter Study Comparative Study
Prospective pulmonary function comparison of open versus endoscopic anterior fusion combined with posterior fusion in adolescent idiopathic scoliosis.
Prospective clinical study. ⋯ VAT versus Open release/anterior fusion in association with a PSF for select AIS curves requiring circumferential treatment both demonstrated similar radiographic and pulmonary function test improvement at 2 years postoperative, with no significant differences seen between the groups.

To describe the management of a patient presenting with intraosseous MPNST of the thoracic spine causing cord compression. ⋯ Intraosseous MPNST causing spinal cord compression has not been described as yet and should be added to the differential diagnosis of primary bone tumors causing cord compression. Prognosis with MPNST can be poor, especially in patients with large tumors, undergoing subtotal surgical resection and in association with neurofibromatosis.

Systematic review of clinical guidelines. ⋯ The quality and transparency of the development process and the consistency in the reporting of primary care guidelines for low back pain need to be improved.

Comparative Study
Biomechanical analysis of transpedicular screw fixation in the subaxial cervical spine.
An in vitro biomechanical study to compare 2 different dorsal screw fixation techniques in the cervical spine with respect to primary stability and stability after cyclic loading. ⋯ The major finding of the current study was the higher stability of pedicle screws over lateral mass fixation with respect to primary stability and stability after cyclic loading. From a biomechanical point of view the use of pedicle screws in the subaxial cervical spine seems justified in patients with poor bone quality and need for multisegmental fixation.
