A prospective interventional study. ⋯ The PASB allows a complete curve correction in most cases. No patients exhibited curve progression.

Cross-sectional study of 45- to 64-year-old Australians. ⋯ This highlights the need to prevent and effectively treat chronic back problems, as these conditions are associated with reduced living standards.

Comparative Study
Adjacent-level range of motion and intradiscal pressure after posterior cervical decompression and fixation: an in vitro human cadaveric model.
This in vitro human cadaveric study measured adjacent-level kinematics after posterior cervical decompression and fixation. ⋯ For C3-C6 laminectomy, instrumentation to C7 significantly decreased flexion/extension ROM and intradiscal pressure at C6-C7 without significantly increasing either measure at C2-C3 or C7-T1 relative to C3-C6 fixation. In the setting of a C3-C7 laminectomy, when instrumenting to either C2 or T2, consideration should be given to including both levels within these constructs.

Retrospective, case-control study. ⋯ The results of this study indicate that LOVBH greater than 50% and LK greater than 20° are not predictive of PLC injury in thoracolumbar burst fractures. Translation greater than 3.5 mm was associated with PLC injury. The PLC and neural elements should be directly assessed with magnetic resonance imaging if there is clinical concern.
