Description
Background Hemipelvic defect could be reconstructed with homolateral proximal femur, and an acetabulum could be smartly created in the trochanter region. Several issues concerning the peculiar reconstruction of hemipelvis and acetabulum with autograft of homolateral proximal femur have not been revealed clearly yet. Methods Seventy cases of radiographic data were investigated and measured retrospectively to determine the maximum diameter that could be contained in the trochanter. A dual-energy X-ray absorptiometry was employed to detect bone mineral density of natural acetabulum and trochanter on eight volunteers to reflect the differences of bone mineral density and determine whether postoperative protection is needed. Finally, a mock operation was designed to reflect the reconstruction method. Results The section of great trochanter was round and the max diameter was 44.2 ± 5.75 mm averagely. The bone mineral density of natural acetabulum was 1.224 ± 0.183 g/cm3 while 0.866 ± 0.132 g/cm3 in the trochanter region, which was lower statistically than the former. The hemipelvis and acetabulum could be well reconstructed with autograft of homolateral proximal femur through mock operations. Conclusions It is feasible to reconstruct the hemipelvis and hip joint with autologous homolateral proximal femur combined with normal-size total hip replacement. Postoperative protection is mandatory for the new acetabulum could not replace the natural one in the level of bone density
