Contamination by metallic elements released from joint prostheses.
When a metallic implant is in contact with human tissues, the organism reacts and a corrosion process starts. Consequently, we might observe liberation of metallic debris and wear. Our purpose is to measure the contamination and the migration of these metallic elements in the surrounding tissues of the implant. Two types of samples have been studied. First type is sample taken on post-mortem ti...
متن کاملContamination and oxydation degre of metallic elements in periprosthetic tissues
The metallic prosthesis used in orthopaedic surgery undergo degradations some years after their implantation. This phenomenon induces metallic element transfer in surrounding tissues. On postmortem and per-operatory samples, we have taken tissues around hip or knee prosthesis. We have determined the composition of the implanted prosthesis by spark spectrometer. In the first step, we manufacture...
متن کاملSystemic levels of metallic ions released from orthodontic mini-implants.
INTRODUCTION Orthodontic mini-implants are a potential source of metallic ions to the human body because of the corrosion of titanium (Ti) alloy in body fluids. The purpose of this study was to gauge the concentration of Ti, aluminum (Al), and vanadium (V), as a function of time, in the kidneys, livers, and lungs of rabbits that had Ti-6Al-4V alloy orthodontic mini-implants placed in their tibi...
متن کاملLevel of contamination by metallic trace elements and organic molecules in the seagrass beds of Guadeloupe Island.
Seagrass bed ecosystems occupy the most important part of coastal shelf in the French West Indies. They also constitute nurseries for many invertebrates and fishes harvested by local fisheries. In Guadeloupe, coastal fish stocks are declining meanwhile several agroecosystems revealed to be heavily contaminated by pollutants (agricultural lands, rivers, mangroves, seagrass beds, and coral reefs)...
متن کاملCustom-made total joint prostheses for temporomandibular joint reconstruction.
BUMC PROCEEDINGS 2000;13:135–138 Jaw joint (temporomandibular joint or TMJ) disease is estimated to affect 30 million Americans, with approximately 1 million new patients diagnosed each year (1). Although many of these patients can be managed with nonsurgical therapies, some patients require surgical intervention. The TMJ is a unique joint in that it does not function independently but works in...
