Multicenter Study Comparative StudyApical vertebral rotation in adolescent idiopathic scoliosis: comparison of uniplanar and polyaxial pedicle screws.
Retrospective radiographic outcome analysis. ⋯ There was little difference in the coronal plane correction of thoracic curves between the 2 types of screws. However, the uniplanar pedicle screw group had a larger proportion of patients with greater thoracic apical vertebral derotation (less residual apical vertebral rotation) compared with the polyaxial screw group. This can be attributed to the increase in rotational leverage afforded by uniplanar screws during intraoperative bilateral direct apical vertebral derotation maneuvers.

Comparative Study Controlled Clinical TrialACDF with the PCB cage-plate system versus laminoplasty for multilevel cervical spondylotic myelopathy.
A nonrandomized controlled trial. ⋯ Both ACDF with the PCB system and laminoplasty are effective therapies for multilevel cervical spondylotic myelopathy. As compared with laminoplasty, ACDF with the PCB system requires a shorter operative time and causes less operative blood loss, but has a higher decrease rate of the cervical ROM and more complications.

Comparative StudyThe intermediate clinical outcome and its limitations of Bryan cervical arthroplasty for treatment of cervical disc herniation.
This is a prospective, consecutive series study to determine the role of the Bryan artificial cervical disc replacement to treat the isolated cervical disc herniation for Chinese patients. ⋯ Cervical arthroplasty had a good intermediate clinical outcome for oriental patients. Definite stabilization and satisfactory mobility were achieved after surgery, with significant neurological symptom improvement observed. For better matched implant, more shapes/sizes of artificial cervical disc need to be made available for the oriental patients.

Comparative StudyLateral lumbar interbody fusion: clinical and radiographic outcomes at 1 year: a preliminary report.
A retrospective review of patients' radiographs and charts. ⋯ The LLIF approach is effective in correcting the coronal plane deformity and in gaining lordosis at individual instrumented levels. They parallelize adjacent end plates to correct the lumbar scoliotic curves. The complications are mostly approach-related and transitory. A larger cohort with long-term follow-up is required to establish the advantages and shortcomings of the procedure.

Comparative StudyRisk factors for postoperative wound infections of sacral chordoma after surgical excision.
A retrospective study, analyzing the risk factors for postoperative wound infections of the sacral chordoma after surgical excision. ⋯ Patients undergoing sacral tumor surgery may be at greater risk for developing wound complications. In this study, it seems that albumin<3.0, operating time >6 hours, and previous surgery may predict those patients that were more prone to developing postoperative wound infection. Using a single surgical team and no instrumentation seems to provide protection against postoperative wound infection in this patient population.
