Abstract

An acetabular reconstruction prosthesis with a piling-cup system is provided, which includes an iliac posterior pile screw, an iliac anterior pile screw, a pubic pile screw, an ischial pile screw, abutments, a 3D (three-dimensional) printed porous titanium mesh cup, locking screws, nuts, and tail cap screws. Four pile screws are the iliac posterior pile screw facing posterior of the ilium, the iliac anterior pile screw facing iliac tubercle, the ischial pile screw running along ischium ramus, and the pubic pile screw running along pubic ramus. A stable prothesis support system is formed in the acetabular reconstruction prosthesis with a piling-cup system, which conforms to the biomechanical characteristics of physiological pelvis, reduces the risk of prosthesis loosening and dislocation, and improves long-term stability of the prosthesis through biological fixation.
