The use of 3D surface analysis techniques to investigate the wear of matt surface finish femoral stems in total hip replacement
Total hip replacement is one of the most common surgical procedures carried out both in the UK and Worldwide. With an increasing number of younger patients undergoing the procedure, there is an emphasis on increasing the longevity of prostheses. The following reports on a number of component …

Drug eluting prosthetic joints through drug cluster morphology control
More than one million joint replacements are performed in the USA annually. However, around 10 % of patients require revision surgery within 10 years with prosthetic joint infections (PJI) as a common reason. PJI has a recurrence rate of 16 %, a mortality rate of 2.5 %, and end-stage treatments …

Finite Element Analysis Of A Test Specimen For Strength Of A Co-polymer Layer At A Bone-implant Interface
… can be applied as an interfacial layer between bone cement and steel implants to improve their performance and life. Finite element (FE) analysis techniques are used to assess the behavior of the interface layer under static and dynamic loading conditions. The material property of the co-polymer …

Development of clinical assessment strategies for patients undergoing total hip arthroplasty (THA)
… In the surgery the head and neck of the femur bone are replaced with a prosthesis whose ball-like head fits into a cup that is inserted into the acetabulum. There are basically two implant technologies being used in the operation, either bone cement is used to fix the prosthesis into the femur …

Assessment of Injection Behavior of Commercially-available Bone BSMS for Subchondroplasty Procedures
<p>Subchondroplasty is a procedure that utilized bone substitutes materials (BSMs) or bone cement to correct bone defects in the subchondral bone. The two main materials used to compose BSMs are poly-methyl-methacrylate (PMMA) and calcium phosphate cement (CaP). Currently, there is no optimal bone …
