The mean follow up was 4.2 years (3 - 8.5); 70% hips were “asymptomatic” , 22% “better” and8% “without changes or worse”. In patients older than 45 years-old, 40% were “asymptomatic”versus 77% in younger than 45 years-old (p=0.03). Mixed impingement presented 37%“asymptomatic” versus 87% in cam and 82% in pincer impingement (p=0.003). In cases withosteoarthritis, 64% were “asymptomatic” versus 79% in whose there were not radiologicosteoarthritis (p=0.225).

Neverthless we have identified some defectsof the stem such as an excessive valgus neck, an insufficient offset for larger stems and a lackof modularity, making soft tissues tension sometimes difficult.The T3 stem was designed with the purpose of correcting these defects. The T3 stem is made ofTitanium alloy with a textured surface finish and is modular. The lateral offset has beenincreased to 42 mm (34 mm for Wagner’s stem) and the cervico-diaphyseal angle has beenreduced from 145° to 138° degrees. Recently, the T3 stem has been substituted by theRestoration having a more varus neck (132° instead of 138°) and 3 sizes of distal stem (insteadof 2). In this retrospective study we have analized the preliminary results obtained with the T3stem.We reviewed the first 30 consecutive cases having an average FU of more than 10 years.We have always used a trans-femoral approach with “prophylactic” distal cable circlage. In nocase an homologous bone graft was used. No re-revision was necessary. 87% of the femursfile:///E|/ISTA2010-Abstracts.htm[12/7/2011 3:15:47 PM]
