Whether bone quality matters or not in durability of total hip arthroplasty? Bone quality matters in durability of total hip arthroplasty

Abstract

Evolution in surgical techniques and prosthetic designs and materials has improved durability of total hip arthroplasty (THA) . As a result, bone quality of the hip joint has become an important risk factor limiting the durability of THA. In preparation of the acetabular bony bed, the subchondral bone or eburnated bone of good bone quality should be preserved. Sockets fixed in joints with atrophic osteoarthrosis were at a higher risk for loosening than those in joints with normotrophic or hypertrophic osteoarthrosis. Femoral components set in the proximal femurs with a stovepipe canal were at a higher risk for loosening than these in the proximal femurs without. To further improve the durability of THA, the issues of poor bone quality and structure of the hip joint should be overcome.
