[A growing acetabular graft. Results of 10 cases of transplantation of the epiphysis of the iliac crest including a vascular pedicle].

Following an experimental work carried out in 1981, the author presents an original technique of acetabular enlargement plasty. This consists in removing a graft from the epiphysis of the iliac crest, with a pedicles comprising its deep iliac circumflex vessels, and in placing this graft on the periphery of the acetabulum in an intra-articular location. The graft had grown in all 10 cases operated at an average age of 8 years after an average lapse of 5 years. The graft accounts for a 6 degrees decrease in the acetabular slope and a 22 degrees increase in the acetabular coverage. The articular congruence was regarded as normal in all hips at the end of growth. This "growing stop" is an alternative to acetabular realignment or enlargement osteotomies.
