Abstract:

To evaluate the feasibility of partial replacement of femoral head with cadaveric hip joint specimens. In two cases of specimens of adult hip portion of simulated femoral head replacement surgery, under the C arm monitoring, using hollow trephine, build bone tunnel along the direction of the femoral neck, remove the weight-bearing area dead bone (simulation), making bone defect area, the appropriate size of the femoral head prosthesis into the area and imaging results show that the femoral head prosthesis and bone defect area peripheral bone matching is good. Preliminary results show that this method has certain feasibility.

Key words: Avascular necrosis of femoral head, Partial femoral head replacement, Precision treatment, Experimental study
