Interposal

The term interposition , derived from the word interposition (German "interposition" or "insertion"), describes in medicine the bridging of major tissue damage, especially to blood vessels , bones , tendons and nerves , through the surgical use of transplants or implants . For this purpose, on the one hand, the body's own tissue can be removed from other areas of the body, which is then referred to as an autologous transplant. On the other hand, it is also possible to use prostheses made from foreign materials such as metals and plastics , for which the term biomaterials is common.

An implant inserted as an interposer is used, among other things, to restore a connection after an injury such as a fracture of a bone or a tear in a tendon . The replacement of a section of an anatomical structure that has been impaired in its function by injury or illness can also be carried out with an interposal. Such a form of application are, for example, vascular prostheses to replace damaged blood vessel sections.

A surgical alternative to an interposal, especially in vascular surgery , is the insertion of a bypass . The implant is not used as a replacement for the damaged area, but as an additional bypass. The decision between graft and bypass is based on the specific medical circumstances, such as the location and extent of the damage and the type and size of the affected vessel.

In the visceral surgery come Koloninterponate used.
