A multiaxial combined and matched type anti-infection semi-pelvic false body comprises an acetabulum and net cup plate wing which is arranged on the top of the acetabulum and can be fixed on a reserved hip bone wing. Two to three universal joints are arranged on the back of the net cup plate wing. The universal joints are opened with a card slot which can be connected with a universal bar. The invention can arbitrarily adjust the height and the point of view of the acetabulum through the combination of the universal joints and the acetabulum to realize the truly anatomical location reconstruction of the hip joint which is not affected by the resection range. The reconstruction of the connection of the pelvic ring and the acetabulum takes the way of universal multi-axis in order to conveniently adjust the location of the acetabulum, thereby assuring the coherence of the limb length after being reconstructed. The location of the acetabulum can be adjusted according to the removal situation of the soft tissue in the operation. Through the sacrum and the contact point of the universal screw of the ischiopubic multi-axis point driven into the pelvic ring, especially multi-nail fixation driven into the lumbar, the hardening stress can be scattered, the hardening stress concentration can be reduced to reduce the complicating disease such as looseness and broken nails.
