Biomechanical in vitro laboratory study. ⋯ Constrained dual-screw fixation characteristics in modern AISF implants can improve resistance to cyclic loading and pullout forces. DC constructs bear the potential to reduce the mechanical shortcomings of AISF.

Observational Study
Transient low back pain development during standing predicts future clinical low back pain in previously asymptomatic individuals.
Longitudinal, observational. ⋯ Transient LBP development during prolonged standing is a positive predictive factor for future clinical LBP in previously asymptomatic individuals. Individuals who experience transient LBP during standing may be considered a "preclinical" group who are at increased risk for future LBP disorders.

Case report. ⋯ The remaining mobility at the nonossified lesion, where the point of the beak-type OPLL compressed the spinal cord, might have caused the myelopathy in this patient. We propose that stabilization with PSI stimulates bone remodeling of nonossified lesions, leading to a reduction of OPLL. This finding provides a clue about the mechanisms responsible for neurological improvement after PSI for T-OPLL.
