Epirubicin is an anthracycline and is widely used in tumor treatment, but has toxic and undesirable side effects on wide range of cells and hematopoietic stem cells (HSC). Osteoblasts play important roles in bone development and in supporting HSC differentiation and maturation. It remains unknown whether epirubicin-induced bone loss and hematological toxicity are associated with its effect on osteoblasts...
In this study, a dynamic elastic-plastic finite element model is used to simulate the bone temperature rise during drilling process. Various rotating speeds and applied forces of the drill bit are investigated to explore the effects of these parameters on the temperature rise within the bone. The results indicate that a drill bit with a higher rotating speed or a higher applied force can have noticeable...
Entry position of the graft is very important in anterior cruciate ligament (ACL) reconstruction. However the determination of entry position is very difficult to the surgeon. In this paper, a navigation and evaluation system assisted by the 6-DOFS robot is implemented for the simulation evaluation and planning insertion points based on quadrant method for the femur and Sta??ublis method for the tibia...
This study develops an analysis method which can be applied to simulating the temperature rise during bone drilling. A three-dimensional dynamic elastic-plastic finite element model is used to simulate the process of a Kirschner pin drilling through a bone. The results indicate that lowering the initial temperature of Kirschner pin can decrease the temperature rise as well as the size of the thermal...
Drilling is an essential part of internal fixation in orthopaedic and trauma surgery. The temperature rise during bone drilling is an important index to the damage of bone. In this study, an elastic-plastic dynamic finite element model is used to simulate the process of a drill bit drilling through the bone. Various initial temperatures of drill bit are investigated to explore the effects of this...
