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 retrospective cohort study aimed to determine the rate and risk factors for S2AI screw-related pain after adult spinal deformity surgery. The study found that 9.6% of patients experienced S2AI screw-related pain, and 3.4% required screw removal. Patients in the pain group showed greater changes in SRS function score and SVA postoperatively.

Summary: This study investigated the morphological accuracy of iliac screw insertion in two low profile iliac fixation techniques. The results showed that compared to the S2AI group, the AI group had better adaptation to pelvic morphology in all parameters and similar low complications as S2AI.

Summary: This study reports the preliminary outcomes of freehand S2AI screw fixation after lumbosacral tumor resection. The results show that this technique has good performance in terms of operative time, blood loss, and screw accuracy, with no observed severe complications. The study also found that the technique is effective in the treatment of lumbosacral tumors.

Summary: Finite element analysis was used to compare five different sacral fracture fixation methods. The S2AI-S1 group displayed the greatest biomechanical stability for Denis type I sacral fractures, making it a suitable alternative when the S1 pedicle screw insertion point is damaged.

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 demonstrates the technical feasibility of using robotic assistance for single position lateral fusion surgery, which eliminates the need for surgical staging while utilizing the precision of robotic adjuncts. The placement of bilateral pedicle screws and S2-alar-iliac fixation in the lateral position was shown to be successful.

Summary: The study found that S2 alar-iliac (S2AI) screw fixation can effectively reduce motion in the lumbosacral joint and decrease screw bending moment. However, this method increases strain on the rods at the lumbosacral junction. The addition of sacroiliac joint fusion did not significantly affect joint range of motion or screw bending, but it decreased strain on the S2AI screws during compression.

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 present study assessed the feasibility, safety, and accuracy of navigated spinopelvic fixation with the use of high-resolution 3D intraoperative imaging and real-time spinal navigation. The results showed successful implantation of S1 screws in 53% and S2AIS in 85% of patients, indicating that navigation technology improved accuracy and reduced surgical time.

Summary: This study evaluated the progression of hip pathology and risk factors after ASD surgery, and identified significant factors such as sex, developmental dysplasia of the hip, baseline KL grade, and S2AI screw fixation. The non-loosening of the S2AI screw was found to be an important factor for KL grade progression in hips undergoing S2AI screw fixation.

Summary: A retrospective study analyzed patients with ASD who underwent long segment spinal fusion with IS or S2AI fixation. The IS technique showed better correction of lumbar lordosis and a possible increase in pelvic incidence compared to the S2AI technique. Further research is needed to determine the clinical implications of these findings.

Summary: This study investigates unexpected deaths resulting from primary brain tumors and analyzes the contributing variables. The findings reveal that unexpected deaths are a complex phenomenon, with headache being the most common initial symptom and meningiomas and astrocytomas being the most common lesions.

Summary: The study found that socioeconomic factors including race, health insurance, and income have an impact on the quality of life at the time of vestibular schwannoma diagnosis. Black/African American and uninsured/self-pay patients had lower quality of life, while patients with higher income had higher quality of life.

Summary: This study systematically reviews models that aim to provide patient-specific predictions of pre-treatment rebleeding risk in patients with aneurysmal subarachnoid hemorrhage. The reported discriminative performance of the models varied, and no model showed consistently low bias risk and clinical applicability in all domains. Only one model was formulated using a patient cohort that underwent contemporary, evidence-based aneurysm treatment practices, but this model lacked calibration or clinical utility.

Summary: This study retrospectively reviewed the clinical characteristics and outcomes after surgical revascularization for adult Moyamoya disease (MMD) in a Southeast Asian cohort. The incidence of postoperative transient ischemic attack (TIA)/stroke was 25.9%, with most cases occurring within 7 days postoperatively. Risk factors for 30-day postoperative TIA/stroke included a higher number of preoperative TIAs/strokes and indirect revascularization.

Summary: This study investigated the forward head posture (FHP), thoracic kyphosis, and their relationship in individuals with migraine compared to healthy controls. The results showed that patients with migraine had a greater FHP and thoracic kyphosis. This suggests that a 3-dimensional objective measurement could be a reliable tool for evaluating posture analysis in clinical practice.
