Cranial surgical site infections (cSSIs) are associated with significant morbidity. Measures to reduce cSSI are necessary to reduce patient morbidity as well as hospital costs and resource utilization. ⋯ The strength of the conclusions is limited by small sample sizes, study heterogeneity, relatively low cSSI incidence, and high case variability. Some evidence supports the use of intraoperative vancomycin powder in adult noncranioplasty cases and the application of accountability, teaching, and surveillance of faculty, particularly those early in training.

The anatomy and spatial relationships of the dural sac comprising the Meckel cave (MC) and its ensheathed trigeminal ganglion (TG) are exceedingly intricate and complex. There are conflicting accounts in the literature regarding the dural configuration of the MC around the ganglion and the dual embryology of the MC and TG is still unclear. ⋯ Sound knowledge concerning the dural arrangement of the MC and the trigeminal divisions will be invaluable in optimally treating cancers in this region, and understanding TG somatotopy will immensely improve treatment of trigeminal neuralgia in terms of specificity, efficacy, and positive patient outcomes.

Various prognostic models are used to predict mortality and functional outcome in patients after traumatic brain injury with a trend to incorporate machine learning protocols. None of these models is focused exactly on the subgroup of patients indicated for decompressive craniectomy. Evidence regarding efficiency of this surgery is still incomplete, especially in patients undergoing primary decompressive craniectomy with evacuation of traumatic mass lesions. ⋯ Random forest algorithms show promising results in prediction of postoperative outcome and mortality in patients undergoing primary decompressive craniectomy. The best performance was achieved by Classification Random forest for 6-month outcome.

Can PEEK Dethrone Titanium as the Choice Implant Material for Metastatic Spine Tumor Surgery?
Instrumentation during metastatic spine tumor surgery (MSTS) provides stability to the spinal column in patients with pathologic fracture or iatrogenic instability produced while undergoing extensive decompression. Titanium is the current implant material of choice in MSTS. However, it hinders radiotherapy planning and generates artifacts, with magnetic resonance imaging and computed tomography scans used for postoperative evaluation of tumor recurrence and/or complications. ⋯ The mechanical properties of PEEK may be improved by forming composites with HA or carbon fiber. Despite these modifications, all PEEK and PEEK-based implants are difficult to handle and contour intraoperatively. Our review provides a comprehensive overview of PEEK and modified PEEK implants, with a description of their properties and limitations, potentially serving as a basis for their future development and use in MSTS.

Jacques Forestier: Forgotten Contributions of a Rheumatologist to Spine Surgery.
Jacques Forestier (1890-1978) was a well-known rheumatologist and radiologist whose innovations have revolutionized spinal neurosurgery and rheumatology. He was well known as "Doctor Lipiodol" for his accidental discovery of spinal myelography, which he later extrapolated for use in many body cavities and their pathologies. He was the first to describe "senile ankylosing hyperostosis of the spine," which was later renamed "diffuse idiopathic skeletal hyperostosis." Furthermore, he is credited with the first use of gold salts as a disease-modifying therapy for rheumatoid arthritis. We have presented a historical vignette to chronicle the life of Jacques Forestier and his contributions to the field of spinal neurosurgery.
