Multicenter Study
Spondylolisthesis, pelvic incidence, and spinopelvic balance: a correlation study.
A retrospective study of the sagittal alignment in developmental spondylolisthesis. ⋯ Since PI is a constant anatomic pelvic variable specific to each individual and strongly determines SS, PT, and LL, which are position-dependent variables, this study suggests that pelvic anatomy has a direct influence on the development of a spondylolisthesis.Study participants with an increased pelvic incidence appear to be at higher risk of presenting a spondylolisthesis, and an increased PI may be an important factor predisposing to progression in developmental spondylolisthesis.

Review Comparative Study
Comparative analysis of pedicle screw versus hook instrumentation in posterior spinal fusion of adolescent idiopathic scoliosis.
A retrospective matched cohort study. ⋯ Pedicle screw instrumentation, although more expensive, offers a significantly better major and minor curve correction without neurologic problems and improved pulmonary function values in the operative treatment of AIS and enables a slightly shorter fusion length than segmental hook instrumentation.

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.

Review Comparative Study
Cotrel-Dubousset (CD) or Universal Spine System (USS) instrumentation in adolescent idiopathic scoliosis (AIS): comparison of midterm clinical, functional, and radiologic outcomes.
A retrospective comparison of the clinical, radiologic, and functional results of Cotrell-Dubousset (CD) and Universal Spine System (USS) instrumentation for adolescent idiopathic scoliosis (AIS). ⋯ The midterm radiologic and functional outcomes were quite similar in both groups as were the SRS scores. The patients performed, on average, as well as did the reference population in nondynamometric trunk strength measurements. Intraoperative and late complications were similar in both 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.
