Abstract
Within a timeframe of 8 years (2008-2016), 38 patients have undergone total hip replacement surgery for coxarthrosis or aseptic necrosis secondary to acetabulum fractures. The study included 27 males and 11 females between 42 and 70 years of age, all of whom came from other institutions. The follow-up period ranged between a minimum of 4.6 and a maximum of 9.7 years. At the final follow-up, all patients were evaluated using the Merle D'Aubigne and Pastel model. Optimal results were found in all the cases. Three patients benefited from surgical revisitation with implant exchange following infection and one/two state reimplatation at seven, fourtheen et twenty-seven months respectively. Two patients benefited from cotyle revision due to chronic instability of the implant. The scope of the study was to present all the possible surgical difficulties that can come up with prosthetic implants. More particularly, hip implants after acetabulum fractures qualifies as a "difficult primary implant".
