To assess the effectiveness and safety of neurological interventions using the right transradial approach (R-TRA) in patients with aberrant right subclavian artery (ARSA). ⋯ R-TRA proves to be a safe and effective option for neuro-interventional surgery in patients with ARSA.

To examine if the use of an antibacterial envelope (TYRX) decreases the rate of postoperative infection in chronic pain patients undergoing treatment with spinal cord stimulation (SCS) involving device implantation. ⋯ The TYRX antibacterial envelope displayed infection rates reducing capabilities, along with a clear tendency to reduce revision surgeries and system removals due to infections.

This study aimed to examine pneumatization and topographic location of the posterior clinoid process (PCP) in Chiari type I malformation (CIM) for skull base approaches. ⋯ The distances of PCP to the crista galli and foramen magnum indicate the anterior fossa length and the posterior fossa depth, respectively; thus CIM patients have a longer anterior fossa and a shallow posterior fossa. In addition, the distances of PCP to the superior orbital fissure, foramen rotundum, and foramen ovale indicate the middle fossa width; hence CIM patients have less middle fossa width than normal individuals. CIM patients have an approximately 50% higher PCP pneumatization rate, and this may increase the risk of complications such as cerebrospinal fluid fistula during the application of posterior clinoidectomy.

The Spinal Instability Neoplastic Score (SINS) classification system is a validated and the most widely accepted instrument for defining instability in vertebral metastasis (VM), in which lesions scoring between 7 and 12 are defined as indeterminate and the treatment is controversial. This study aimed to determine which variables more frequently are considered by spine surgeons for choosing between the conservative and the surgical treatment of VMs among patients with an indeterminate SINS. ⋯ Surgeons relied on mechanical pain and type of metastatic lesion for treatment choices. Vertebral collapse, spinal malalignment, and mobility were less influential. Spinal mobility was a predictor of surgical versus non-surgical treatment. The only variables not identified either by surgeons themselves or as a predictor of surgery selection was the presence/degree of posterolateral/posterior element involvement.

The occurrence of surgical site infection (SSI) after lumbar spinal fusion is a serious complication. Therefore, an increasing number of clinicians are applying vancomycin powder topically in the surgical field to reduce the incidence of SSI. However, there is concern that topical vancomycin powder application may affect intervertebral fusion. The purpose of this study was to analyse the effect of clinically relevant topical vancomycin doses on the rate of intervertebral fusion after lumbar fusion and to further investigate the effect of vancomycin powder on the prevention of SSI. ⋯ Topical application of 0.5 g, 1.0 g, or 1.5 g vancomycin powder did not affect the rates of intervertebral fusion after lumbar fusion. In addition, topical application of vancomycin powder significantly reduced the rates of SSI.
