Comparison of different fixation methods of bicolumnar acetabular fractures.

Objectives: This study aims to investigate if the stabilization of iliac wing fractures influences the stability of the acetabular osteosynthesis, if surgical fixation is the choice of treatment, and which technique to be used.

Materials And Methods: In the study, measurements were performed with an improved finite element model. Tension and displacement values were measured in bicolumnar acetabular fractures in the following cases: combination of cranial and medial plate fixation through the linea terminalis, or combination of cranial plate and quadrilateral surface plates.

Intrapelvic acetabulum surgery: does the positioning of the plate fixation play a role in the stability of the osteosynthesis?

Objectives: This study aims to investigate whether positioning of the plate fixation plays a role in the stability of the osteosynthesis.

Materials And Methods: We used finite element modelling to model an anterior pillar fracture and a T-type fracture of the acetabulum. Fracture fixation was carried out in three different variations: cranially positioned plate, medially positioned plate, and a combination of the two methods.

Does surgically fixation of pubic fracture increase the stability of the operated posterior pelvis?

Objectives: This study aims to investigate whether surgical treatment of pubic rami fractures increases the stability of the posterior pelvis.

Patients And Methods: A finite element pelvic model with improved geometric and material characteristics was analyzed. By imitating a standing position, a type I Denis sacrum fracture and a unilateral pubis fracture, we measured the differences in tension and displacement.

Further development of our finite element pelvic model to compare fixation methods for pelvic fractures.

Objectives: In this study, we aimed to create a realistic model which is suitable for computerized simulation of any kind of fractures and provides reliable results.

Patients And Methods: We used a plastic pelvic model to construct advanced specimens. The data were retrieved from the computed tomography scans of a healthy pelvis.

How bilateral iliolumbar fusion increases the stability of horizontal osteosynthesis in unstable pelvic ring injuries?

Objective: In type C pelvic ring injuries, the operative stabilization of the posterior ring is absolutely indicated. There exist four different types of operative methods: iliosacral screw fixation, transsacral plate synthesis, ventral plate fixation (primarily for sacroiliac luxations), and local plate synthesis performed on the dorsal cortex of the sacrum. In our current article, we analyzed the stability of fixation methods used together with bilateral iliolumbar techniques.
