An implant like a hip-stem replacement necessitates integration with the host tissues, and protein adsorption facilitates this integration. Surgical tools can be designed to be sterilized more easily so that proteins do not remain adsorbed to a surface, risking cross-contamination.
Protein adsorption influences the interactions that occur at the tissue-implant interface. Protein adsorption can lead to blood clots, the foreign-body response and ultimately the degradation of the device. In order to counter-act the effects of protein adsorption, implants are often coated with a polymer coating to decrease protein adsorption.
Immediately following insertion, an implant (and the tissue damage from surgery) will result in acute inflammation. The classic signs of acute inflammation are redness, swelling, heat, pain, and loss of function. Hemorrhaging from tissue damage results in clotting which stimulates latent mast cells. The mast cells release chemokines which ...
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]
An implant is a medical device manufactured to replace a missing biological structure, support a damaged biological structure, or enhance an existing biological structure. 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 ...
Treatments may include medication, not walking on the affected leg, stretching, and surgery. [1] Most of the time surgery is eventually required and may include core decompression, osteotomy, bone grafts, or joint replacement. [1] About 15,000 cases occur per year in the United States. [4] People 30 to 50 years old are most commonly affected. [3]
It is performed to alleviate pain, and is a salvage procedure, reserved for condition where pain can not be alleviated in any other way. It is common in veterinary surgery. Other names are excision arthroplasty of the femoral head and neck, Girdlestone's operation, Girdlestone procedure, and femoral head and neck ostectomy. [citation needed]
Bone morphogenetic protein (rhBMP) should not be routinely used in any type of anterior cervical spine fusion, such as with anterior cervical discectomy and fusion. [13] There are reports of this therapy causing swelling of soft tissue which in turn can cause life-threatening complications due to difficulty swallowing and pressure on the ...
