Summary: This study simulated the surgical procedure in Chinese patients to determine the ideal insertion point, diameter, length, and angle of the infra-acetabular screw. The results provide valuable guidance for secure screw placement and highlight gender-dependent differences in screw dimensions and insertion point. Further biomechanical studies are recommended to validate the screw's function.

Summary: This study aimed to explore the relationship between the infra-acetabular corridor diameter (IACD) and the minimum thickness of medial acetabular wall (MTMAW) to clarify the way of screw placement. IACD and MTMAW showed significant differences between males and females, with males having wider measurements. The placement mode of the infra-acetabular screw (IAS) can be determined preoperatively by measuring the MTMAW in the CT axial layers, with differences in entry point location between the all-in screw and in-out-in screw groups based on gender.

Summary: This study explored the entry point, orientation, and fixation range of retrograde acetabular posterior column screw through the use of computed tomography data and three-dimensional reconstruction. The results showed that the screw's entry point is located at the midline between the medial and lateral edges of the ischial tuberosity, which is 1.3 cm far from the distal ischial tuberosity. This screw can be used to fix acetabular posterior column fractures that are not 4 cm above the femoral head center.

Summary: The study evaluated the consistency of standard pelvic radiographs compared with CT scans in demonstrating articular penetration of infra-acetabular screws, and found that the outlet view is an accurate method for detecting hip joint penetration of such screws.

Summary: This study found that the acetabular configuration affects the safety of infra-acetabulum screw insertion, with the distance between the screw and the femoral head decreasing as the depth of the acetabulum increases. Female patients, in particular, need to be aware of the risk of screw mispositioning.

Summary: The diameter and insertion rate of the infra-acetabular corridor vary under different fluoroscopic angles, with the best angle being 15 degrees and 25 degrees, and the lowest at 45 degrees. However, the corridor length increases as the fluoroscopic angle increases, while the angle of the corridor axis gradually decreases.

Summary: Based on a 3D model test, the study provides recommendations for screw size, entry points, and angles for Ogawa type I acromial fractures, offering valuable guidance for clinical practice. More accurate screw parameters can be obtained preoperatively by establishing an individualized 3D model.

Summary: Modified iliac screws can be safely placed percutaneously with intraoperative image guidance. Surgeons can easily adjust the screw head to align with S1 pedicle screw via the same small incision without the need for rod connectors.

Summary: The aim of this study was to evaluate if the ADAPT system reduces the number of outliers with a TAD > 20 mm. Unfortunately, the results showed that the use of the ADAPT system did not meet the expectation, as there were still outliers with a TAD > 20 mm. Therefore, the use of the ADAPT system was discontinued.

Summary: This study aimed to determine the size of the S1-transsacral corridor amenable to TS screw placement and its associations with gender, ethnicity, and screw breach. The results showed that no S1-TS screws were placed in corridors less than 8 mm. There was no significant difference in screw breaches between small (<10 mm) and large (>= 10 mm) corridors.

Summary: The incidence of pertrochanteric hip fractures is increasing due to the aging population. Despite advancements in techniques and implants, failure rates remain high. Recognizing challenging fracture patterns and meticulous preoperative planning play a crucial role in avoiding common pitfalls. Understanding fluoroscopic views for reduction assessment and implant placement is essential for preventing fixation failure. Additionally, adjunctive techniques can facilitate reduction efforts.

Summary: This study evaluated the clinical effectiveness of a novel infra-pectineal quadrilateral surface buttress plates for the treatment of geriatric acetabular fractures. The results showed that this method provided stable and effective fixation to the quadrilateral surface involved acetabular fractures in elderly patients, and satisfactory clinical outcomes with few complications were observed.
