Summary: Sacral osteotomy combined with triangular osteosynthesis is an effective method for the treatment of malunion and nonunion of vertically displaced pelvic fractures. It can significantly correct the vertical displacement of the pelvis, prolong limb length, and reconstruct the stability of the pelvic ring, achieving good clinical results.

Summary: This study evaluated the biomechanical stability of S2 alar-iliac screw and S1 pedicle screw fixation in treating Denis II sacral fractures. The results showed that S2 alar-iliac screw and S1 pedicle screw fixation had significant advantages in terms of relative displacement and gap angle, providing good stability for the fracture models.

Summary: This study aimed to investigate the surgical methods and clinical effects of lumbopelvic fixation (LPF) with S2 alar-iliac (S2AI) screws for U-shaped sacral fractures. The results showed that LPF with S2AI screws for the treatment of U-shaped sacral fractures has distinct advantages, including firm fixation, a low rate of surgical site complications, and satisfactory clinical efficacy.

Summary: The purpose of this report is to demonstrate a new technique for creating a 4-rod lumbosacral construct when stacked S2AI screws are not possible due to concurrent treatment of sacroiliitis. The technique involves using a combined S2AI and subcrestal iliac approach to achieve the construct, while providing biomechanical support to the S2AI screws and treating the sacroiliitis.

Summary: This study compared S2 alar-iliac screw (S2AIS) trajectories between males and females using pelvic three-dimensional computed tomography (3D-CT) in a normal Japanese population. The study found that the angulation of S2AIS was more lateral in the axial plane and more horizontal in the coronal plane in females. Females also had shorter distances from the midline to the starting points of S2AIS and longer distances from the midline to the posterior superior iliac spine.

Summary: This study evaluated the clinical outcomes of S2AI and IS techniques in lumbopelvic reconstruction for lumbosacral tuberculosis patients, finding that the S2AI group had shorter operation time and less intraoperative blood loss compared to the IS group. Both groups showed significant improvement in postoperative outcomes, with no significant difference in remission degree observed between the two groups.

Summary: The study introduces a new technique using S1-Al screw fixation for sacral and iliac fixation, which requires less dissection and allows for easier rod connection. This technique may be considered for salvage in cases of severe loosening in the sacrum during short-segment revision fusions.

Summary: The study found no significant differences in stability between the MI, TI, and S2AI screw techniques, but the MI screw has the advantage of lower prominence and a more medialized starting point, eliminating the need for offset-connectors.

Summary: The percutaneous SI screw is commonly used for posterior ring disruption in pelvic fractures, but its placement is difficult and can damage adjacent neurovascular structures. The SAI screw is a safe and reliable technique for sacral pelvic fixation. Finite element analysis showed that SAI screws provided biomechanical stability for SI joint dislocation. Various fixation methods achieved sufficient stability, with the TS1 + TS2 group having the smallest displacement and lowest peak screw stress. These findings suggest that SAI screws are a valuable option for treating SI joint dislocation.

Summary: S2AI screw for sacropelvic fixation shows better outcomes in terms of pelvic obliquity, re-operation rates, implant failure rates, implant prominence, pseudarthrosis, wound infection, and blood loss compared to iliac screw. This alternative fixation method seems to have lower incidence of postoperative complications and better radiological outcomes.

Summary: The study found that the ODI total score and most subscale scores were significantly, but weakly correlated with coronal parameters, while sagittal parameters were only correlated with some of the ODI and SF-36 subscale scores. Analysis using ODI and SF-36 subscale scores may help in understanding and treating disability in patients with DLS.

Summary: This study investigated the outcomes of postoperative discitis treated with debridement and a novel technique focused on reducing outpatient antibiotic requirement in a low- and middle-income country (LMIC) setting. The results showed that patients with medically refractory postoperative discitis potentially have good outcomes after debridement plus 2-week local antibiotic instillation in LMICs.

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.
