The main surgical methods of hip joint are iliac inguinal approach, posterior lateral approach, inferior median incision approach, anterior-posterior joint approach, etc. The main fixation methods are plate screw fixation, external fixation bracket fixation, tension screw fixation, and fixation with a kyphotic pin.

There is also a big difference in the cost of domestic and imported materials, and the general cost is 20,000 to 100,000.
