Objective:
To determine the efficiency and clinical outcome of impaction bone graft in revision total hip arthroplasty (THA).
Methods:
Seventy-two revision THAs by using impaction bone graft in 48 patients with severe bone loss were gotten average 25 months follow-up. Harris hip scores and X-ray were used to evaluate the results.
Results:
The mean Harris hip scores improved from 44.6 before operation to 87.4 after operation. The excellent and good results were 90.3%. No stem subsidence and cup migration were found. Femoral fracture rate was 4.2%, and dislocation rate was 1.4%.
Conclusion:
Impaction bone graft is an efficacious method to restore bone stock in revision THA, and using anatomic stem and freeze-drying cancellous bone allograft could also get good clinical result.
