“…In addition, some cases of incomplete QLP fractures affecting the anterior and posterior columns were also identified. In 2023, Chen et al [ 18 ] evaluated QLP fractures using a new classification system. Their classification was based on the anterior or posterior column fractures of the Judet-Letournel classification and the partial or complete separation of QLP from the columns.…”

Background A new classification system for acetabular fractures has been proposed in recent years, which is called the 3-column classification. However, this system does not provide information regarding quadrilateral plate fractures. To address this issue, we utilized three-dimensional (3D) fracture line mapping and heat map to analyze the link between the 3-column classification and quadrilateral plate fractures. Methods We collected CT scan data from 177 patients who had been diagnosed with acetabular fractures. Additionally, we utilized a CT scan of a healthy adult to generate a standard acetabular model. We utilized the collected CT data of the fracture to create a 3D model and subsequently reduced it. We then matched each acetabular fracture model with the standard acetabular model and mapped all of the fracture lines to the standard model. 3D fracture lines and heat maps were created by overlapping all fracture lines. Fracture characteristics were then summarized using these maps. Results This study analyzed a total of 221 acetabular fractures. The most frequently observed fracture type, based on the three-column classification, was A1.2, which corresponds to fractures of the anterior column. In contrast, the least common type of fracture was A4, which represents fractures of the central wall. It was noted that quadrilateral plate fractures were frequently observed in fractures classified as type B and C according to the three-column classification. Conclusions Among the three-column classification, the QLP fractures are commonly observed in type B and C. It is important to carefully identify these fractures during the diagnostic process. Therefore, based on the three-column classification, we have amalgamated quadrilateral plate fractures and formulated a classification program for acetabular fractures.

During the last two decades, extended scientific interest focused on quadrilateral plate (QLP) fractures as part of common acetabular fractures. The QLP corresponds to the medial wall of the acetabulum, and different fracture pattern of Letournel´s fracture types are associated with concomitant QLP fractures. Except anterior and posterior wall fractures, all other fracture types may be associated with QLP fractures. QLP fracture features include simple fracture lines up to highly comminuted fractures. A detailed preoperative analysis of these fractures is important to get a better understanding of intraoperative decision making. No consensus exists regarding the optimal classification and treatment of QLP fractures. Various operative approaches and treatment concepts exists depending on the specific QLP fracture type and the acetabular fracture type. Several new implants were development for optimal but often individual stabilization concepts. The gold-standard is still some medial buttressing during internal fixation predominantly using plates, but also screw fixation is considered an option. Additional dome impactions must be considered as an integral part in any QLP fracture analysis and stabilization.

The quadrilateral surface fractures of the acetabulum are becoming more frequent due to the aging population. The optimal fixation of the quadrilateral surface through an appropriate surgical approach and a reliable and effective technique presents a challenge for orthopedic trauma surgeons. In this study, we present the results of 12 patients treated in our department who underwent internal fixation of the quadrilateral surface with two reconstruction plates in a vertical orientation for adequate fracture buttressing. The clinical and radiological outcomes are encouraging, and we believe that this low-cost technique can be a reliable method for optimal fixation of acetabular quadrilateral surface fractures.
