These results are very encouraging. However, in patients with severe bone loss, higher rates of revision have been reported and good and excellent results have been less frequent. Longer -term results and a larger number of patients are needed to provide the final answer about the validity of this technique. The doctors of the Rothman Institute are encouraged enough about the results of impaction grafting to be using it in a selected group of patients. Complications of impaction grafting Rates of dislocation, infection , and phlebitis are similar to the rates in other types of hip revision surgeries.
Perforation occurs most commonly during component and cement removal.
In contrast, fracture of the femur usually occurs during placement of the cancellous bone graft or the femoral prosthesis. Both perforation and fracture may require additional surgery. Fracture of the femur around the prosthesis is another well-described complication of this technique of revision hip surgery. These technique- related complications can be reduced by careful selection of patients and through proper technique of surgery. Another complication of this technique is subsidence or settling of the femoral prosthesis within the femoral canal.
