An intramedullary rod, also known as an intramedullary nail (IM nail) or inter-locking nail or Küntscher nail (without proximal or distal fixation), is a metal rod forced into the medullary cavity of a bone. IM nails have long been used to treat fractures of long bones of the body.
The Ilizarov apparatus is a specialized external fixator of modular construction, composed of rings (stainless steel, titanium) that are transfixed to healthy bone with Kirschner wires and pins of heavy-gauge stainless steel, and immobilised in place with additional rings and threaded rods that are attached with and through adjustable nuts. The ...
Titanium is considered the most biocompatible metal due to its resistance to corrosion from bodily fluids, bio-inertness, capacity for osseointegration, and high fatigue limit. Titanium's ability to withstand the harsh bodily environment is a result of the protective oxide film that forms naturally in the presence of oxygen.
Orthopedic implant example seen with X-ray. An orthopedic implant is a medical device manufactured to replace a missing joint or bone, or to support a damaged bone. [1] The medical implant is mainly fabricated using stainless steel and titanium alloys for strength and the plastic coating that is done on it acts as an artificial cartilage. [2]
For example, an implant may be a rod, used to strengthen weak bones. Medical implants are human-made devices, in contrast to a transplant, which is a transplanted biomedical tissue. The surface of implants that contact the body might be made of a biomedical material such as titanium, silicone, or apatite depending on what is the most functional ...
Titanium foams exhibit high specific strength, high energy absorption, excellent corrosion resistance and biocompatibility. These materials are ideally suited for applications within the aerospace industry. [1] [2] [3] An inherent resistance to corrosion allows the foam to be a desirable candidate for various filtering applications.
The classic surgical procedure entails entering two titanium rods, each roughly 1.5 feet (0.46 m) long (depending on the size of the kyphosis) into the back on either side of the spine. Eight titanium screws and hardware are drilled through the bone to secure the rods onto either side of the spine.
Titanium may be anodized to vary the thickness of the surface oxide layer, causing optical interference fringes and a variety of bright colors. [124] With this coloration and chemical inertness, titanium is a popular metal for body piercing. [125] Titanium has a minor use in dedicated non-circulating coins and medals.
