TH15822C3 - Orthopedic shank to be used with orthopedic cement - Google Patents

Abstract

Page 1 of the number 1 page, a summary of the invention. Hip joint prosthesis in combination with orthopedic cement The main structure is composed of a Morse cone (Morse taper) (1) The cone is angled between 4? Up to 7? serves to connect to the head of the bone hip joint The prosthesis neck (2), which is small, gradually descends towards the base. This increases the degree of movement while the angle of the prosthesis joint (3) is between 120? Up to 132? to suit Thai anatomy The ridge of the prosthesis (4) is straightened obliquely. design to avoid head bone to optimize surgery As for the tool holder to hold the prosthesis shaft (5), it is indented towards the inside. Connecting the axis of the hip joint of the prosthesis In order to use the device to hold the artificial hip shaft in the surgical procedure to avoid the head bone to increase the efficiency of surgery. The torso of the hip prosthesis (6) is designed as a double taper in order to taper according to the bone cavities. It plays an important role in ensuring that the cement holds the bone with a consistent thickness, preventing the fracture of the cement. The artificial hip joint is designed in both normal and high angle designs. The height of the hip prosthesis is between 115-175 mm.
