Summary: In the aging population, secondary vertebral compression fractures following primary osteoporotic vertebral compression fractures are a significant concern. Age, history of nonspinal fractures, and Hounsfield units value of L1 were identified as independent risk factors associated with secondary vertebral compression fractures.

Summary: This study identified risk factors for subsequent fractures in the thoracolumbar segment after vertebral augmentation, including previous fracture, intravertebral cleft, fatty infiltration of psoas, and body angle restoration rate. Refractures were more likely to occur when the body angle restoration rate exceeded 0.350.

Summary: Among patients with osteoporotic vertebral compression fractures (OVCFs) who underwent vertebral cement augmentation, the incidence of further fractures in sandwich vertebrae is not higher compared to adjacent vertebrae. Male gender was identified as a potential risk factor for sandwich vertebral fractures. Patients with sandwich vertebral fractures may be more likely to pursue surgical intervention than those with only adjacent fractures.

Summary: This study investigates the incidence and risk factors of vertebral re-fracture after percutaneous vertebroplasty and kyphoplasty. The results suggest that female sex, older age, lower bone mineral density, and bone cement leakages increase the risk of re-fracture. The occurrence of re-fracture is significantly associated with gender, age, and bone mineral density in Eastern Asia. Anterior-to-posterior vertebral body height ratio and visual analog scale score are higher in the refracture group, while kyphotic angle correction ratio is smaller in Eastern Asia. Anti-osteoporosis treatment may serve as a protective factor.

Summary: The study retrospectively analyzed 2344 patients who underwent PVP or PKP for OVCFs. It found that multiple involved vertebrae, thoracic fracture, operation timing, and operation methods are independent risk factors for PCE. The real incidence of PCE may be underestimated without routine postoperative pulmonary imaging examination.

Summary: This study aimed to investigate the risk of sandwich vertebral fractures in the treatment of osteoporotic vertebral compression fractures via percutaneous vertebroplasty (PVP) and percutaneous kyphoplasty (PKP). The study found that PVP had a higher risk of sandwich vertebral fractures compared to PKP, potentially due to the larger amount of bone cement, higher rate of cement leakage, and larger Cobb angle.

Summary: A meta-analysis of 6 studies found no significant difference in the incidence of new vertebral compression fracture, adjacent vertebral fracture, and remote vertebral fracture between prophylactic vertebral augmentation group and nonprophylactic group. Therefore, current evidence does not support the efficacy of prophylactic vertebral augmentation in preventing refracture, suggesting a need for further research on refracture mechanisms and alternative preventive regimens.

Summary: This study comprehensively evaluated the risk factors for subsequent fracture following vertebral augmentation. It identified previous fracture, cement leakage, postoperative lumbar lordosis (LL), and correction of body angle (BA) as independent risk factors. The study also found that the correction of BA should not exceed 3.45 degrees, especially in patients with risk factors.

Summary: The study investigated risk factors for vertebral re-fracture post-PKP for OVCF. Age, number of operative vertebral bodies, degenerative scoliosis, and anti-osteoporosis treatment were significantly associated with re-fracture. Degenerative lateral curvature was identified as an independent risk factor and possible risk factor for re-fracture post-PKP.

Summary: This study aimed to examine the clinical incidence rate of vertebral body fractures after percutaneous vertebroplasty (PVP) with and without brace wearing and provide a new guiding ideology for preventing vertebral fractures after clinical surgeries. The results showed that the incidence of vertebral refracture was lower in the brace-wearing group and the improvement in JOA scores was better in the soft brace group.

Summary: Vertebroplasty is a common treatment for painful osteoporotic vertebral fractures, but the timing of the procedure varies between centres and regions. Studies have shown mixed results, with some indicating more benefit from early vertebroplasty and others showing no additional benefit compared to placebo. This review examines data from both blinded and open label randomised studies to specifically evaluate the use of early vertebroplasty for patients with severely painful acute osteoporotic fractures.

Summary: This study aimed to evaluate the risk factors of refracture in elderly patients with osteoporotic vertebral compression fracture (OVCF) patients after percutaneous vertebroplasty (PVP) and construct a predictive nomogram model. Univariate and multivariate logistic regression analyses were performed to identify risk factors, and a nomogram prediction model was constructed and evaluated based on these risk factors. The AUC of the constructed nomogram model based on six factors was 0.812 with a specificity and sensitivity of 0.787 and 0.750, respectively.

Summary: This study compared the efficacy of uniportal lumbar endoscopic unilateral laminotomy with bilateral decompression (UPE) and biportal endoscopic unilateral laminotomy with bilateral decompression (BPE) in the treatment of lumbar spinal stenosis. The results showed no significant differences in operative duration, intraoperative blood loss, and length of hospital stay between UPE and BPE. However, the UPE group had a higher rate of intraoperative complications. Both endoscopic decompression techniques showed significant clinical improvement during the follow-up period.

Summary: Personalized care models in modern medicine are rooted in teaching future physicians the necessary skill set to keep up with innovation. Orthopedic surgery and neurosurgery are increasingly influenced by technologies such as augmented reality, robotics, and artificial intelligence. The postpandemic learning environment has shifted towards online learning and competency-based teaching models. Work-hour restrictions in postgraduate training programs have made it challenging for residents to acquire the necessary knowledge and skills for certification. The fast-paced innovation in these fields requires higher efficiencies in the training environment.

Summary: Chronic lower back pain is a major cause of disability in the musculoskeletal system. Degenerative disc disease is a significant contributing factor to chronic back pain in the aging population worldwide. The sinuvertebral nerve and basivertebral nerve are postulated to be the main mediators of nociceptive response in degenerative disc disease due to their neurotization. This review discusses the pathoanatomy, pathophysiology, and pain generation pathway in degenerative disc disease and chronic back pain, as well as management strategies for sinuvertebral and basivertebral neuropathy.

Summary: Corticocortical evoked potentials (CCEPs) have emerged as a valuable intraoperative monitoring technique in eloquent brain tumor surgery, aiding in preserving critical functional areas. Current research shows the potential of CCEPs in guiding surgical decision making, reducing the risk of postoperative neurological deficits, and mapping functional connectivity, but further research and standardization are needed.

Summary: This study aimed to compare the effect of different Modic changes (MC) grades on the cage subsidence rate after spinal interbody fusion surgery. A meta-analysis was conducted on relevant randomized controlled trials and cohort studies. The results showed that MC may be associated with a higher cage subsidence rate. With the increase in MC grades, the incidence of subsidence decreased gradually, but it was always higher than that in the non-Modic changes (NMC). Oblique lumbar interbody fusion may be a better treatment choice for lumbar degenerative disease with MC.

Summary: Early exposure to neurosurgery during medical school is critical for improving recruitment into the specialty. However, about 30% of medical schools in the U.S. lack a neurosurgery program, limiting students' exposure to the field. Virtual education, facilitated by webinars during the pandemic, has advantages such as global outreach and accessibility for international medical students. This review identifies and describes 16 educational resources, serving as a guide for medical students interested in neurosurgery.
