Prosthetic hip joint
A prosthetic hip joint is a complex prosthetic assembly process. Hip prostheses previously installed for patients with hip dislocation (unilateral) and hemipelvis resections usually require walking stick assistance. Nowadays, with the improvement of the performance of assembly hips and knee joints and the improvement of the assembly process, proper training is performed after the limbs are assembled. Even if it is a hemipelvis resection prosthetic arm, it is completely possible to walk barefoot.
At present, most of the hip prostheses assembled in China are made of modular hip joints produced by the Otto Bock Company of Germany. The main hip joints are 7E4, 7E5 and 7E7. 7E4, 7E5 is a modular hip joint with an external extension assist device (rubber strap). The joint hinge and the center adjustment disc are made of alloy steel; 7E5 and 7 E4 are distinguished from 7E5 with a manual hip joint lock, which can be used at the station and Locking the hip joint while walking is suitable for patients with high stability requirements (older people). The 7E7 is a modular hip joint with built-in extension assist (spring). The extension spring is installed in the tube and the joint body is made of titanium alloy. Compared with 7E4 or 7E5, 7E7 is not only small in size, high in strength and good in appearance, but also easier to adjust the line.
