Grafting In Total Hip Arthroplasty In Acetabular Bone Defect Reconstruction Applied Research

Objective: To explore the suppressed bone in total hip acetabular revision surgery in the reconstruction of bone defects of the methods and results.Methods: 12 cases of 12 of the hip after total hip replacement prosthesislateral acetabular osteolysis around the prosthesis led to loosening and wear of acetabular prosthesis in patients with dislocation of the femoral head center, the renovation of total hip acetabular bone defect suppressed-sik Acetabular bone reconstruction surgery, 12 cases were unilateral hip joints, are the standard Harris hip score (Table 1) and surgery before and after the regular X-ray evaluation, renovation, when the average age of all patients 67-year-old (55～80 years old).Results: 12 patients, follow-up period was 6 months -3 years, an average of 1. 6 years, mean preoperative Harris score was 47.1 points, the final follow-up increased to 88.0 hours. All patients were in the three months after full load, the original hip pain relief, deformity disappeared. In the final follow-up, there were 10 cases of femoral stem prosthesis into the bone was fixed, and one cases of femoral shaft fractures due to plate fixation prosthesis after dislocation led to the renovation again. Complications included 1 case of femoral shaft fracture, in order to handle cutting-edge Department spiral femur fracture,postoperative dislocation. The group without a fixed prosthesis failure patients, no infection.Conclusion: The suppression of acetabular bone graft for reconstruction of bone cement fixation of the acetabulum to provide adequate initial stability, and provide a good support role, better integration with the host bone without the weak points of the machine and gradually over time strengthening.
