Incidental Durotomy in Open Versus Tubular Revision Microdiscectomy: A Retrospective Controlled Study on Incidence, Management and Outcome.
Retrospective case-control study. ⋯ The incidence of durotomy and postoperative CSF-fistula in lumbar revision microdiscectomy does not significantly differ between minimal-access and standard open procedures. The application of a fibrin sealant patch alone is an effective strategy for dural repair in revision lumbar microdiscectomy.

Biomechanical evaluation of the pedicle screw insertion depth effect on screw stability under cyclic loading and subsequent pullout.
A biomechanical ex vivo study of the human lumbar spine. ⋯ Although increased screw depth led to increased fixation and decreased loosening, additional purchase of the stiff anterior cortex is essential to reach superior screw-bone construct stability and stiffness.

Anterior or posterior surgery for right thoracic adolescent idiopathic scoliosis (AIS)? A prospective cohorts' comparison using radiologic and functional outcomes.
Prospective cohort study. ⋯ Patients with right thoracic AIS of differing curve types but otherwise similar preoperatively demonstrated that anterior and posterior surgery are largely equivalent. Patient-reported outcomes are improved similarly by either approach. Both offer excellent radiographic and trunk deformity correction. Differences in the effect of sagittal alignment, operative time, and complications should be considered when selecting approach.

Radiation exposure to surgeon in minimally invasive transforaminal lumbar interbody fusion with novel spinal locators.
A prospective study. ⋯ The study indicated that radiation exposure to the surgeon would be effectively reduced in MIS-TLIF using our surface locator and intradermal locator, and it could be another practical choice for radiation-minimizing strategy.

Lumbar facet joint effusion on MRI as a sign of unstable degenerative spondylolisthesis: should it influence the treatment decision?
Retrospective study. ⋯ Although mindful of the limitations of this retrospective study, we conclude that the effusion sign alone does not seem to be an indication for adding fusion to decompression in the treatment of LDS. Hence, the presence of the facet effusion sign should not, in itself, deter the surgeon from performing decompression alone. However, the phenomenon should be investigated in larger samples of patients, ideally within a randomized trial.
