Aseptic Loosening of Total Hip Arthroplasty as a Result of Local Failure of Tissue Homeostasis

摘要: Total hip arthoplasty (THA) is the most effective and safest method for treating severe degenerative, post-traumatic other diseases of joint. It estimated that more than 1,000,000 THAs are performed each year globally. The incidence primary THA increased in period 1990 to 2002 USA from 47/100,000 69/100,000 (Kurtz et al. 2007). A similar study Denmark reported an rate 101/100,000 131/100,000 during 1996 (Pedersen 2005). More importantly, modelled future projections expect further increase need THAs. believed can reliably relieve pain improve function majority patients a 15 20 years or postoperatively. On this basis, with extension younger generally active population, expected time service would be insufficient number revision surgeries therefore time. Kaplan-Meier ten-year revision-free survival estimates range 72% (95%CI: 67-76) Finland 86% 84,5-88,2) Sweden (Corbett 2010). Hence, 14% 28% such on average did not achieve 10-year functioning without revision. main reason late failure aseptic loosening accompanied by osteolysis followed infection instability compromise early postoperative
