Aseptic loosening in cemented custom-made prosthetic replacements for bone tumours of the lower limb.
We have made a retrospective study of 1001 custom-made prostheses used as replacements after surgery for bone tumours. There were 493 distal femoral, 263 proximal femoral and 245 proximal tibial prostheses. Aseptic loosening was shown to be the principal mode of failure of the implants, and 71 patients had revision for aseptic loosening of a cemented intramedullary stem. The probability of a pa...
متن کاملDoes bone quality predict loosening of cemented total hip replacements?
We matched 78 patients with a loose cemented Charnley Elite Plus total hip replacement (THR) by age, gender, race, prosthesis and time from surgery with 49 patients with a well-fixed stable hip replacement, to determine if poor bone quality predisposes to loosening. Clinical, radiological, biomechanical and bone mineral density indicators of bone quality were assessed. Patients with loose repla...
متن کاملStanmore custom-made extendible distal femoral replacements. Clinical experience in children with primary malignant bone tumours.
The use of extendible distal femoral replacements is a relatively new treatment alternative for malignant bone tumours in growing individuals. Although their appearance was widely appreciated, questions about functional practicality and longevity remain unclear. With longer follow-up, advantages of immediate functional restoration and beneficial psychological aspects seem to be overshadowed by ...
متن کاملHypersensitivity in aseptic loosening of total hip replacements. The role of constituents of bone cement.
Aseptic loosening is seen in a significant proportion of cemented total hip replacements (THR). In a small subgroup of patients who suffer early loosening polyethylene debris is unlikely to be responsible. We recently reported one case of allergic contact dermatitis to N,N-dimethylparatoluidine (DMT), an accelerator used in bone cement. We have therefore investigated this using skin-patch tests...
متن کاملA Hydroxyapatite Coated Collar Reduces Aseptic Loosening of Cemented Distal Femoral Massive Bone Tumour Prostheses
Background: Aseptic loosening of massive bone tumour implants remains one of the major causes of prosthesis failure. Question: The hypothesis of this study was that an osteointegrated hydroxyapatite (HA) coated collar would reduce the incidence of aseptic loosening around the cemented intramedullary stem in distal femoral bone tumour prostheses. Methods: Twenty-two patients were pair matched in...
