Background
As patients who undergo total hip arthroplasty continue to grow in age and exercise capacity, the number of hip revision surgeries continues to increase. The failure of the primary total hip replacement requires revision of the hip for many reasons, including infection, wearing of the polyethylene lining of the prosthesis, and habitual dislocation of the prosthesis. The dissolution of bone around the prosthesis caused by the abrasion debris of the prosthesis and the aseptic loosening of the prosthesis are always the main reasons for the hip revision surgery. In the face of revision of hip joint after primary hip joint replacement failure, the strategy and technique of acetabulum side defect repair and reconstruction operation are one of the challenges for orthopedists

In the face of increasing patients with hip revision surgery, the principle of acetabular bone defect treatment is to recover and preserve the bone mass of the patients as much as possible, obtain sufficient prosthesis coverage rate to ensure good initial stability of the prosthesis, and generate fusion redistribution among bone graft, implant and host bones. Initial prosthesis stabilization can ensure sufficient bone fusion and bone growth, and good bone growth contributes to the long-term stability and survival rate of acetabular prosthesis components. Before an operation, the bone defect condition of a patient needs to be fully known, the bone defect is classified to make an operation strategy, and the internal articles possibly needed in the operation are fully prepared.

At present, the acetabulum side reconstruction strategy of the acetabulum minor bone defect patient is more consistent when the acetabulum minor bone defect patient is clinically applied, but the selection of bone grafting, metal built-in objects, bone cement application and the like of the acetabulum major bone defect patient is controversial. The typing methods are all evaluated based on X-ray films, and the accuracy is low.
Aiming at the problem that the accuracy of an evaluation result obtained by evaluating the acetabular bone defect in the hip revision surgery in the related art is low, an effective solution is not provided at present.
