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.

Long-term systemic metal distribution in patients with stainless steel spinal instrumentation: a case-control study.
Case-control study. ⋯ Cr testing is suggested as a reliable marker for the malfunctioning assessment and as a support for standard procedures, especially with doubtful diagnosis. Furthermore, high levels of Cr ions were observed in female patients. This finding deserves attention especially when counseling young fertile women.

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.

Cement augmented anterior odontoid screw fixation is biomechanically advantageous in osteoporotic patients with Anderson Type II fractures.
A biomechanical human cadaveric study. ⋯ Cement augmentation for fixation of osteoporotic type II odontoid fractures showed biomechanical advantages. It was also shown that cement augmentation of the newly developed screw is technically easy and safe under in vitro conditions. The technique might be useful with regard to the surgical treatment of elderly patients with osteoporotic odontoid fractures.
