Finite Element Modelling of NiTi Shape Memory Alloy Abutment for an Osseointegration Trans-femoral Implant
Traditionally, prosthetic limb is interconnected to the residual limb via a “socket”. As the body weight upon the prosthesis is transferred through soft tissue to human skeleton, the muscles and skin could be traumatized. To overcome the problem, an osseointegration trans-femoral implant technique has been used to attach prosthetic limb to human skeleton directly. However, due to the malfunctio...
متن کاملEnhancement of Implant Osseointegration by High-Frequency Low-Magnitude Loading
BACKGROUND Mechanical loading is known to play an important role in bone remodelling. This study aimed to evaluate the effect of high- and low-frequency axial loading, applied directly to the implant, on peri-implant bone healing and implant osseointegration. METHODOLOGY Titanium implants were bilaterally installed in rat tibiae. For every animal, one implant was loaded (test) while the other...
متن کاملNumerical evaluation of bone remodelling associated with trans-femoral osseointegration implant--A 68 month follow-up study.
Osseointegrated trans-femoral implant is a relatively new orthopaedic anchoring method for connecting a stump with a prosthesis. Through a follow-up study of a patient over six years, significant bone remodelling has been observed. Finite element (FE) simulations were carried out to investigate the relationship between the bone remodelling and the strain re-distribution around the trans-femoral...
متن کاملBiology of implant osseointegration.
Osseointegration refers to a direct structural and functional connection between ordered, living bone and the surface of a load-carrying implant. Currently, an implant is considered as osseointegrated when there is no progressive relative movement between the implant and the bone with which it has direct contact. A direct bone contact as observed histologically may be indicative of the lack of ...
متن کاملStability analysis for a peri-implant osseointegration model.
We investigate stability of the solution of a set of partial differential equations, which is used to model a peri-implant osseointegration process. For certain parameter values, the solution has a 'wave-like' profile, which appears in the distribution of osteogenic cells, osteoblasts, growth factor and bone matrix. This 'wave-like' profile contradicts experimental observations. In our study we...
