ABSTRACT
Objective. Determine the radiological graft integration; analyze the graft integration rate, and describe the technical features that favor a better graft integration.
Introduction: Acetabular dysplasia has represented a problem for cementless total hip replacement, in terms of both covering the acetabular implant and achieving the right orientation. Reports show that en-bloc grafts may result in increased patient morbidity.
Methods: Coverage of the superolateral region of dysplastic acetabular was done with a head and neck graft harvested from the patient at the time of surgery and fixed with screws to the iliac bone; then reaming was performed to place the acetabular implant. Acetabular coverage was done in 18 patients using this procedure, 17 females and one male; mean age was 39 years, and mean follow-up was 52 months.
Results: Patients were clinically evaluated from the standpoint of symptoms, muscle strength, mobility and regular x-rays. All patients had 100% integration of the head and neck bone graft and the expected acetabular coverage was achieved.
Conclusion: Many of the techniques described to provide acetabular coverage in dysplastic hips undergoing replacement may involve increased patient morbidity. Autografts have always been safer and reduce the risk of morbidity.
