Minimally invasive techniques are increasingly used in traumatic surgery. Compared to open surgery, these methods present several advantages in terms of reduced morbidity, speed of recovery and quality of fracture reduction. However, due to the restricted area of exposure resulting from limited skin incision, direct observation of the bone fragments is not possible. For surgeons, thorough pre-operative planning and in-depth understanding of the biomechanical behaviours become necessary to define the optimal positioning of the surgical tools during the surgery to ensure efficient fracture reduction and stabilization.
This webinar spotlights how clinicians use Ansys Mechanical to create two patient-specific finite element models for evaluating the optimal fracture reduction and stabilization. Learn how they use Mechanical to model the geometry and behavior of fractured bone material and its interaction with surgical material.
The first model corresponds to fracture reduction, which consists of restoring the height of the bone structure with surgical balloon inflation. The second evaluates the stabilization technique including different lengths of screw and whether to perform PMMA cement injection or not.
Additionally, geometry extraction from 3D X-ray images of the patient, meshing, material properties allocation, surgical tool modelling and boundary conditions will be described.
Lastly, we will examine how clinicians use an interactive digital twin of the patient to analyze the impact of different reduction and stabilization solutions, in terms of mobility and constraints, for optimizing the surgical gestures per patient.
