Megjegyzések:	AbstractBackground The incorporation of bulk bone grafts in thereplacement of dysplastic acetabulum is determined by thebiological environment of the recipient site, the size of thecontact surface, and the stability of the osteosynthesis used.Based on these, the present study compares the Harrisacetabular plasty used routinely by us with the Radojevic?L-shaped graft technique.Methods For our measurements, we used 20 hemi-pelvisesremoved from 10 cadavers. In 10 cases, acetabularplasty according to Harris, in 10 cases Radojevic? L-plasty,was performed. The biological environment was analyzed;with geometric calculations, the contact surface wasdetermined, and with a material testing apparatus, theprimary stability of the osetosynthesis was measured. Forthe measurements, a new method was developed.Results The Radojevic? technique provides a better biologicalenvironment for graft ingrowth. The contact surfaceis nearly twice as much as in Harris plasty. No significantdifference was found in the primary stability of the osteosynthesisused. The deviation on the value of the stabilitymeasurements is explained by the differences in the bonequality of the cadavers used.Conclusions Based on the 3 aspects examined, the Radojevic? L-shaped graft technique has similar stability whencompared to the Harris acetabular plasty, but providesbetter biological circumstances and larger graft host bonecontact. Based on this, we started using the L-shapedtechnique in our department.
