Since 2006 we have started to implant modular stelus, ceramic articolar component and Delta cotilus (PF 2006.2007 and TT since 2008) in hip artroplastic of young patients. 53 implantations (4 cases bilateral). Association with conic stelus (14th different shapes from 13 to 26) with trocanterical modulus that permits a good compliance studing each cases (offset-AR-lever-arm). We have found a good resolution using ceramic as matherial in articolar joint because reaching a very high level of satisfaction both for surgeons and for patients outfits. The Delta TT Lima has a titanium trabecular surface that offers a very good primary stability and a very high level in bone integration. The dedicated instrumentary, the design and the matherial high quality are the bases for a good resistance and a good articolar stability. Medium age of patients was 51 y.o. (from 33 to 66 y.o); follow up has been made at the 1st year and the 6th year. Results were evaluated following HHS guide line. Main treated pathologies were: primary arthrosis (9 cases); DCA (21 cases), post thraumatic arthrosis (9 cases), OA (8 cases), hip fractures (6 cases).
