A long-term follow-up study of total hip replacement with bone graft. Correlations between roentgenographic measurement and hip mobility.

Fifty total hip replacement treating the acetabular deficiency with autologous bone graft from the femoral head were performed on 44 patients with congenital dislocation of the hip. The average age was 55 years. The average follow-up period was 5 years and 2 months, ranging from 3 years, 8 months to 6 years, 11 months. Solid union was demonstrated in all acetabular grafting. No loosening of either acetabular or femoral components occurred. Roentgenological measurements used as a parameter of good results showed that better results were obtained using the true acetabulum (ideal position) with appropriate bony coverage.
