Cemented Total Hip Arthroplasty In Dogs
Total hip arthroplasty (THA) is an excellent salvage procedure for debilitating conditions that included osteoarthritis, hip luxation, femoral head and neck fracture and revision of femoral head ostectomy providing excellent hip joint function. Six dogs with clinical condition of hip dysplasia with luxation (three), severe osteoarthritis (two) and hip luxation (one) weighing 30 kg b.wt were sub...
متن کاملCemented total hip arthroplasty with retention of some existing hardware.
We report a case of a 63-year-old man who presented an end stage hip osteoarthritis 42 years after a proximal femoral osteotomy performed for the treatment of an intracapsular femoral neck fracture. A cemented total hip arthroplasty was implanted using a standard posterior approach. The osteotomy hardware was totally covered with a new cortical bone formation. A layer of bone tissue was removed...
متن کاملEfficacy of alumina ceramic heads for cemented total hip arthroplasty.
Fifty-seven cemented total hip arthroplasties (THAs) were reviewed in cases of osteoarthrosis secondary to congenital dysplasia or dislocation. The bearing surface of the prosthesis used in this series consists of a polyethylene acetabular component on an alumina ceramic head. All acetabular components were positioned at the same level as the original acetabulum, and an autologous femoral head ...
متن کاملPre-heating of components in cemented total hip arthroplasty.
Fatigue fractures which originate at stress-concentrating voids located at the implant-cement interface are a potential cause of septic loosening of cemented femoral components. Heating of the component to 44 degrees C is known to reduce the porosity of the cement-prosthesis interface. The temperature of the cement-bone interface was recorded intra-operatively as 32.3 degrees C. A simulated fem...
متن کاملUncemented and cemented primary total hip arthroplasty in the Swedish Hip Arthroplasty Register
BACKGROUND AND PURPOSE Since the introduction of total hip arthroplasty (THA) in Sweden, both components have most commonly been cemented. A decade ago the frequency of uncemented fixation started to increase, and this change in practice has continued. We therefore analyzed implant survival of cemented and uncemented THA, and whether the modes of failure differ between the two methods of fixati...
