Body Implants Failure Analysis
Body implants or orthopedic implants are artificial devices mounted in human body to support bone, replace bone or joints, and reattach ligaments. There are two types of body implant devices namely, prosthetic and internal fixation devices. Body implants called as prosthetic devices are designed to remain in the body for a lifetime and are used as joint replacements or as bone replacements for example, after tumor resection. Internal fixation devices provide temporary stabilization. After healing, internal fixation devices are normally removed from the body.
The term implant failure indicates breakage or disintegration of an implant such that it cannot fulfill its intended function. Body implants can fail due to reasons like bone resorption, breakage of bone, loosening or bending of implants, etc.
Besides ceramics and polymers materials, orthopedic implants include metals and alloys like stainless steels, unalloyed titanium, titanium alloys, cobalt-chromium-molybdenum alloy, etc.
Fatigue, corrosion, corrosion-fatigue, wear, fretting, overload, etc. are some of the most frequently encountered causes of failure of body implants.
We at TCR are well-equipped to investigate the root-cause of failure of body implants in consultation with medical experts using analytical tools and techniques like optical and scanning electron microscopy coupled with EDAX, Image analysis, and other destructive & non-destructive testing techniques. TCR has a team of experts having a strong background in areas like metallurgy and materials science, corrosion science & polymer chemistry and mechanical engineering, Finite Element Analysis, to name a few.
