[Reconstruction of acetabular insufficiency in initial total hip endoprosthesis surgery using a massive autograft (fate of the implanted autograft more than one year after surgery)].

The authors present a method of reconstruction of insufficient acetabula by autografts from heads of femurs before primary implantation of the cemented total endoprosthesis of the coxa. They reconstruct the osseous acetabulum of the patient by prolonging it, filling or reinforcing its floor, although in one third of the patients it is difficult to find a borderline between these three groups. Coxarthroses are primary and secondary and of those almost half are secondary dysplastic coxarthroses. The group of patients comprises 32 women and 17 men, their mean age at the time of operation was 58.5 years. The authors follow-up, using clinical and X-ray methods, the fate of "massive autografts". Within six months the autograft is already firmly linked with bone and within 12 months it is reconstructed. A bone graft, unless burdened, is gradually reabsorbed. This process is intensive in particular between the 3rd and 6th month after operation and by the 12th month the graft is reabsorbed.
