Biomechanics of noncemented total hip arthroplasty
Biomechanical research on noncemented total hip arthroplasty has not kept pace with the rate with which new devices have been introduced and tested in the clinic. Although promising clinical results of noncemented total hip arthroplasty are published in the peer·reviewed literature, many problems have been reported as well and long-term follow-up studies are scarce_ Due to the variety of fixati...
متن کاملBiomechanics of Hip Arthroplasty
The biomechanics of the hip joint has been of great interest to researchers and clinicians since the early days of anatomical studies. Julius Wolff addressed the relation between the inner architecture of the bone and the functional loading already in the nineteenth century [31] and Friedrich Pauwels built the foundation for a mechanical approach to understand joint loading 65 years later [24]....
متن کاملBiomechanics of failure modalities in total hip arthroplasty
Total hip arthroplasty (THA) is the treatment of choice to relieve joint pain and loss of mobility as a result of advanced stage osteoarthritis or other hip pathologies. Despite their general success, THAs do fail, with revision rates estimated near 5% per year. Instability, defined as the complete subluxation (dislocation) of the femoral head from the acetabular socket – which usually occurs d...
متن کاملNoncemented total hip arthroplasty for osteonecrosis of the femoral head in elderly patients.
The results of total hip arthroplasty (THA) for osteonecrosis of the femoral head (ONFH) in elderly patients (80 years or older) has not been well defined. The purpose of this retrospective study was to evaluate the clinical course of and the results in noncemented THA for ONFH in elderly patients.Between 1998 and 2007, one hundred seven consecutive hips with ONFH in 103 patients were evaluated...
متن کاملAdaptive bone remodeling and biomechanical design considerations for noncemented total hip arthroplasty.
Clinical problems with noncemented total hip arthroplasty (THA) stems, directly or indirectly related to load transfer, include mid-thigh pain due to relative (micro) motions or excessive endosteal interface stresses, subsidence and loosening due to inadequate primary stability and fit, and proximal femoral bone atrophy due to stress shielding. In this article, the load-transfer mechanisms asso...
