Clinical Trial
Patient preferences and expectations for care: determinants in patients with lumbar intervertebral disc herniation.
Prospective observational cohort. ⋯ Patient expectations, particularly regarding the benefit of nonoperative treatment, are the primary determinant of surgery preference among patients with lumbar intervertebral disc herniation. Demographic, functional status, and prior treatment experience had significant associations with patients' expectations and preferences.

Multicenter Study
Radiographic predictors for the development of myelopathy in patients with ossification of the posterior longitudinal ligament: a multicenter cohort study.
A multicenter cohort study was performed retrospectively. ⋯ Static and dynamic factors were related to the development of myelopathy in OPLL.

Comparative Study
Biomechanical comparison of a novel C1 posterior locking plate with the harms technique in a C1-C2 fixation model.
A biomechanical testing protocol was used to study atlantoaxial fixation techniques in a human cadaveric model. ⋯ A novel C1 posterior locking plate was designed and tested in a C1-C2 fixation model. The C1 locking plate technique functioned in an equivalent manner to the existing Harms technique. The C1 plate may be a viable alternative that is technically less demanding with decreased surgical risk.

Randomized Controlled Trial
Efficacy and safety of prophylactic large dose of tranexamic acid in spine surgery: a prospective, randomized, double-blind, placebo-controlled study.
This is a double blind randomized placebo controlled study, after obtaining approval of ethics committee in the hospital and informed written consent, 64 patients were randomized equally into 2 groups (tranexamic acid (TA) and placebo). ⋯ Prophylactic use of large doses of TA provides an effective, safe, and cheap method for reducing blood loss during and after spinal operations. Hence, TAmay help in reducing not only transfusion related complications but also operative expenses. Considering the limited number of patients in this study, our results need, however, to be validated on a larger number of patients, probably in a multicenter study.

Multicenter Study Comparative Study
Comparison of compensatory curve spontaneous derotation after selective thoracic or lumbar fusions in adolescent idiopathic scoliosis.
Retrospective review of a multicenter prospectively collected series of adolescent idiopathic scoliosis (AIS) patients. ⋯ Axial plane rotational correction of the unfused minor curve in patients undergoing selective fusions does occur. Significant spontaneous correction of a thoracic rib hump after a selective lumbar fusion should not be anticipated, whereas an approximate 50% reduction in the lumbar prominence was the average after selective thoracic fusions.
