Custom made endoprostheses were used in 18 patients with median follow-up 65 months. "We conclude that diaphyseal endoprostheses offer a good clinical and functional outcome in the lower limb"

Most joint-replacement surgeries are currently performed in community hospitals. We sought to determine whether the functional outcomes of joint replacement surgery differ between academic and community hospitals.
Conclusion: There is no significant difference in the functional outcomes of joint-replacement surgery between academic and community hospitals. Further work will involve evaluating cost of...

originally Charnley used High Density Polyethylene and later this was changed to Ultrahigh Molecular Wt Polyethylene
- impact strength of UHMWPE is higher than that for HDPE and the density of UHMWPE is much lower than for...

Of the number of participants in the study, 1.02% of rural and 0.80% of urban beneficiaries underwent a total knee or hip replacement surgery in 2005. Results showed 27% more rural beneficiaries were likely to have total knee or hip replacement surgeries than Medicare recipients in urban areas.
Rural Medicare Beneficiaries...

Rivaroxaban is the first oral direct Factor Xa inhibitor approved in Canada for the prevention of venous thromboembolism (VTE) following elective total hip replacement (THR) and total knee replacement (TKR) surgery. The purpose of this article is to review the available information on rivaroxaban.

In 2004, 234,000 total hip replacements (THRs) and 478,000 total knee replacements (TKRs) were performed in the United States. Treatment of the diseased hip or knee joint does not end with surgical replacement. The ultimate goal is ensuring pain-free function of the joint to improve the patient's quality of life...

The history of total joint replacement has been about basically three things: Firstly, finding the right materials that can function safely and effectively as biomaterials in long-term implants. Early attempts have used such disparate materials as ivory, cellophane, fascia lata, chromacized...

Abstract:Uncemented short-length diaphyseal segmental replacement prosthesis fixation - Finite element analysis and long-term results
Journal of Orthopaedic Research Volume 23, Issue 5 , Pages 1065 - 1072 Published Online: 1 Jan 2006
Conclusions: A short-length fixation system based on intramedullary anchorage of segmental replacement endoprostheses would possibly support physiologic adaptive processes more than fixation...
