Asymptomatic Chronic Dislocation of a Cemented Total Hip Prosthesis
Dislocation of a total hip prosthesis is a painful and mentally stressful orthopaedic emergency.1 It may be long-standing and asymptomatic, typically involving the femoral portion.2-4 This report describes a peculiar chronic dislocation of both components of a total hip prosthesis. A 93-year-old female patient, thin and of short stature, had come to our attention for recent onset of lumbar pain...
متن کاملCemented versus uncemented femoral components in the ring hip prosthesis.
A prospective, randomised and independently assessed trial of the Ring UPM total hip replacement showed that the quality of the early result was better if the femoral prosthesis was cemented than if it was not. More patients with cemented prostheses were painfree at four months (58% cemented:42% uncemented) and at one year (63% cemented:50% uncemented), but at two years pain relief was equal in...
متن کاملRadiological loosening after cemented hip replacement for juvenile chronic arthritis.
We reviewed the results of 14 total hip replacements in patients with juvenile chronic arthritis. The mean age at operation was 16 years (range 12 to 22 years); follow-up was from four to 11 years (mean 8.5 years). Postoperatively pain relief was sustained in all but one hip, while movement generally remained significantly restricted. No hip has as yet required a revision operation, although ei...
متن کاملLong-term clinical and radiological results of the Lord total hip prosthesis. A prospective study.
We enrolled 98 patients (107 hips) with a mean age of 47 years (SD 8.6) into a prospective study of the Madreporic Lord THR; 34 hips had primary and 73 secondary osteoarthritis. After ten years, the survival rate using revision as the endpoint for failure was 70% (+/-9) for the cup and 98% (+/-0.3) for the stem. The combined clinical and radiological survival rates were 46% (+/-11) and 81% (+/-...
متن کاملToward verified and validated FE simulations of a femur with a cemented hip prosthesis.
BACKGROUND Verified and validated CT-based high-order finite element (FE) methods were developed that predict accurately the mechanical response of patient-specific intact femurs. Here we extend these capabilities to human femurs undergoing a total hip replacement using cemented prostheses. METHODS A fresh-frozen human femur was CT-scanned and thereafter in vitro loaded in a stance position u...
