Osteoporosis has been widely known as a reoccurring issue with the increase of age. By understanding key mechanical properties of bone, researchers can better understand methods to induce bone growth as a possible method for osteoporosis reversal. This study uses image modeling to characterize the natural frequency of normal bone by using Finite Element Methods (FEM). Results indicate that the natural...
One of the basic principles for internal fixation is the achievement of stable construct for proper bone healing. Locking compression plate (LCP) achieved it through locking screws that create a fixed-angle construct providing angular stability. The plate and screws combination to construct a stable fixation depends on factors such as the type of fracture and surgical preference. The optimum combination...
Anterior Cruciate Ligament (ACL) reconstruction is performed to recover the injured knee which often happens in sports activity such as skiing, and basketball. The ACL reconstruction makes two bone tunnels in the femur and tibia. Then, the harvested graft passes the bone tunnels so that the femur and tibia are connected. The graft is fixed to the femur by using EndoButton. However, loosening of the...
Background: Treatment of malignant tumors of the pelvis, especially in the periacetabular region continues to present one of the most challenging problems in oncological and orthopedic surgery. Even now, hindquarter amputation is still the only choice for some patients, but hindquarter amputation can cause much trouble in sitting, standing and in fitting the exoprosthesis of patients after amputation,...
In this work, we introduce an extension of the linear elastic tensor-mass method allowing fast computation of non-linear and visco-elastic mechanical forces and deformations for the simulation of biological tissue. We aim at developing a simulation tool for the planning of bone surgical treatment based on CT data of special patient. Surgery simulation requires accurate modeling of the mechanical behavior...
