For femoral fracture reduction, we have developed a surgical robotic system. Indirect traction is employed in our system. Indirect traction in fracture reduction is a generally used surgical method for preventing complications such as bone splits caused by high stress on bones. For traction, a patientpsilas foot is gripped by a jig and pulled to the distal side. Indirect traction has the advantage...
A new method for fluoroscopic tracking of a proximal bone fragment in femoral fracture reduction is presented. The proposed method combines 2-D and 3-D image registration from single-view fluoroscopy with tracking of the head center position of the proximal femoral fragment to improve the accuracy of fluoroscopic registration without the need for repeated manual adjustment of the C-arm as required...
Perichondrium has been shown to elicit signals to suppress differentiation and proliferation of chondrocytes during endochondral bone formation based on in vitro organ culture . However, these in vitro organ cultures did not allow the growth of bone collar, and thus the effect of perichondrium in a normal environment where development of adjacent embryonic tissues, including bone collar, is taking...
