Randomized Controlled Trial
Comparison of Endoscopic Facet Joint Denervation to the Percutaneous Technique Regarding Efficacy in Patients With Low Back Pain: A Randomized Controlled Trial.
This was a single-center prospective randomized controlled study. ⋯ Percutaneous and endoscopic FJD reduced pain and improved functionality and quality of life. However, the effects decreased or disappeared in the PG after 12 months, whereas there was still a strong significant improvement in the EG.

A retrospective comparative study. ⋯ Pedicle measurements made on pMRI may be used with reasonable reliability to predict pedicle dimensions visualized on iCT, allowing surgeons to preoperatively plan pedicle screw sizes based off magnetic resonance imaging.

Prospective cohort study. ⋯ Preexisting adjacent segment disc degeneration, as indicated by disc height and disc bulge, was associated with reduced adjacent segment motion after ACDF, while lack of preexisting adjacent disc degeneration was associated with increased adjacent segment motion after ACDF. These findings provide in vivo evidence supporting early instability and late stabilization in the pathophysiology of disc degeneration.

Prospective study of patients undergoing elective spinal deformity surgery with repeated testing for circulating metal ions including preoperative levels acting as controls. ⋯ The persistent and rising levels of titanium, in a predominantly female population, is concerning. Titanium is known to cross the placental barrier and enter the circulation of the fetus in rodents and humans, and to accumulate in solid organs especially the liver, spleen, heart, and lymph nodes in humans. This potentially exposes the offspring of mothers with spinal implants to titanium, with potential teratogenic effects.
