摘要： An external proximal femoral prosthesis for total hip arthroplasty (THA) is described, which fundamentally comprises a shell configured a hollow, thin-wall, asymmetric bell shape and a plurality of tension anchor means. An inner transverse cross contour of the shell forms a cavity, which could be affixable to a profile of outer surface of the area of neck, trochantic bed and calcar of the proximal femur. A neck portion of the shell is compatible with acetabular components (ball and cup). The prosthesis is mechanically fastened by tension anchor means during the operation and further biologically secured by in-growing bone through the side holes on the shell wall and into its interior coating surface of implant wall thereafter. The loading force on the femoral head would be well transferred and distributed on the shell and then directly conducted into the cortical bone of the femoral shaft therearound.
