Existing approaches neither provide an accurate prediction of subarachnoid hemorrhage (SAH) nor offer a quantitative comparison among a group of its risk factors. To evaluate the population, hypertension, age, size, earlier subarachnoid hemorrhage, and location (PHASES) and unruptured intracranial aneurysm treatment score (UIATS) scores and develop an Artificial Intelligence-based 5-year and lifetime aneurysmal rupture criticality prediction (ARCP) score for a set of risk factors. ⋯ The PHASES and UIATS are weak predictors, and the ARCP score can identify, and grade, risk factors associated with SAH.

Neurosurgical residency applicants' prior research experience can amplify their ability to stand out to prospective neurosurgery programs. We attempted to accurately quantify the number of research publications coauthored by applicants by analyzing the publications of applicants who matched into neurosurgery in the 2021 Match. ⋯ Students matriculating to neurosurgery residency programs display a wide range of research productivity. Typical U.S. Doctor of Medicine and Doctor of Osteopathic Medicine applicants have coauthored a mean of 5.1 and a median of 4.0 publications. This information may assist program directors in weighing applicants' research background and give medical students interested in the field reasonable research expectations.

To develop and validate a nomogram for predicting recurrent lumbar disk herniation (LDH) within 2 years after percutaneous endoscopic lumbar discectomy. ⋯ We developed and validated a new accurate and effective nomogram for predicting recurrent LDH within 2 years after percutaneous endoscopic lumbar discectomy. Age, body mass index, Modic change, Pfirrmann grade, and sagittal range of motion were significant features for predicting rLDH.

Central nervous system tumors are the most common solid neoplasm in children, 60%-70% occurring in the posterior fossa. Surgery is the mainstay of treatment but surgery in the pediatric population is associated with a high risk of perioperative complications. We aimed at analyzing the perioperative complications after posterior fossa surgery in a pediatric population and identifying the associated risk factors. ⋯ Surgery in the posterior fossa in the pediatric population harbors a high risk of complications. Identifying the variables contributing to these complications is important in order to improve surgical management of these patients.

C1 lateral mass fractures (LMF) cause abnormal alignment of the upper cervical joints. Conservatively treated cases can develop into late cock-robin junction, requiring a reconstructive surgical procedure of the occipitocervical junction. Partial coronal C1 LMF could be effectively fixed with lag screws. Navigation and robot-assisted techniques have made percutaneous fixation possible and are gradually being used in the upper cervical spine. ⋯ Robot-assisted percutaneous lag screw osteosynthesis is a viable option for C1 LMF. Different approaches can be selected according to the distribution of the fracture lines. With the posterior approach, the guidewire tends to deviate from the entry point because of skiving, and the technical problems need to be further solved. Screw implant by a transoral approach is comparatively easy to achieve, but the possibly of infection exists and should be monitored.
