To investigate the biomechanical properties of pedicle screw reinsertion along the same trajectory in a previously validated synthetic bone model. ⋯ Despite a significant decrease in insertion torque, there is no significant loss of pedicle screw performance when a screw is removed and reinserted along the same trajectory.

To evaluate current usage and barriers of electronic consent (e-consent) implementation in neurosurgical practice. E-consent forms provide an alternative method for conducting the informed consent (IC) procedure. IC requires an ability to understand, retain, weigh up, and communicate decisions regarding the proposed procedure. Currently, e-consent has shown promise as a method of improving IC, yet barriers to implementation exist. ⋯ Despite the advantages conferred by e-consent for the administration of IC in neurosurgical procedures, reflected in our survey data, there remains limited use of the technology. Limitations remain relating to ease of access and complexity of use in trauma scenarios.

Chronic risk factors of posterior circulation ischemic strokes remain unknown. There is, however, evidence that anatomical variations within the vertebrobasilar system could potentially lead to the development of posterior circulation strokes. We investigated the association of forward head posturing (FHP), a chronic anatomical change seen in patients with cervicalgia, with posterior circulation strokes. ⋯ This case-control matched-pair study found that in adults with cervicalgia, posterior circulation ischemic stroke was associated with more severe FHP as noted in C0-C2 angle and sagittal vertical axis shift measurements. Further, this association may be due to chronic changes in circulation flow dynamics within the vertebrobasilar system with the postural change.

Transcallosal Retroforniceal Transchoroidal Approach: To the Posterior Third Ventricle and Beyond.
The transcallosal retroforniceal transchoroidal approach represents an advanced neurosurgical technique that allows access to lesions located within the posterior third ventricle and mesencephalon. It relies on a comprehensive understanding of microsurgical anatomy and embryology, integrating modern neurosurgical operative techniques to minimize retraction and injury to the normal neuronal structures. ⋯ Through a detailed description of the surgical approach and anatomy, we illustrate the feasibility of the transcallosal retroforniceal transchoroidal approach for accessing lesions located deeply in the brain.

Medical illustrations represent a precious resource for learning surgical anatomy and surgical techniques, allowing preoperative and postoperative reviews. As traditional hand-drawn illustrations are difficult to use and expressing the area of neurointerventional surgery is time-consuming, we proposed methods for neurointerventional surgeons to create digital illustrations (DIs) for neurointerventional surgery using the iPad-exclusive Procreate application (Savage Interactive, Hobart, Australia). ⋯ DIs are also versatile, allowing easy intrainstitutional and interinstitutional sharing and discussion of technical tips on the manipulation of medical devices (coils, catheters, stents, etc.) among neurointerventional surgeons worldwide. DIs can be applied as educational tools not only in neurointerventional surgery, but also in craniotomy surgery and for surgical records from other specialties.
