What is the graft of tendons?
tendon graft is a piece of tendon taken from the donor place and then used to reconstruct the damaged tendon. When tendons are subject to serious damage, such as complete tearing, grafts of tendons are often the only way to heal them. Less serious tendon injuries, on the other hand, can often be addressed by non -surgical approaches such as prolonged rest, immobilization and anti -inflammatory drugs.
tendons are strong but flexible fibrous tissue strips that attach the muscles to the bones. The ligaments are closely related structures connecting bones with other bones. Due to the anatomical similarities between tendons and ties, the tendon grafting is used not only to repair the tendons; It is also used to repair some damaged bonds.
Perhaps the most common use of slips of tendons is the reconstruction of the anterior crossed ligament (ACL). ACL is the main support ligament of the knee and is one of the most often injured ties in sports. In the reconstruction of ACL, Štěp Šlachys are generally taken from patellar tendons or tendons. Both of these tendonsY are good candidates for ACL reconstruction due to their width and length. Normally, Štěp Šlachy should come from a tendon with a similar shape and size to the tendon undergoing reconstruction.
Some tendon exchange instances require a two -stage repair process. This approach uses temporary prosthetic grafts, which are left for several months. Temporary grafts give the body time to prepare a healthy environment for the last graft of tendons. Surgeons are considering two -stage repair based on the specific circumstances of the injury. For example, if a patient has damage to flexor tendons in his hands and a lot of time has passed since the initial injury, a two -stage process may be given.
tissue for grafts can be harvested from one of the two main sources: autogenic tissue or donor tissue. Autogenic tissue concerns the tissue taken from somewhere in the patient's own body. The graft donor's tissue comes from most often fromdeceased persons who made their tissues available for medical purposes. Medical grafts consisting of autogenic tissue are known as autographs, while those that consist of donor tissue are known as aloštepy.
usually will be the first choice for grafts of autograph. The reason why autographs are usually preferred is that aloštpas can bring additional risks. These risks include the transfer of diseases from the donor to the patient and the potential response to immune rejection. While aloštěpé preparations such as freezing to eliminate fibroblasts causing rejection, significantly reduce these risks, the preparations themselves also have disadvantages. One disadvantage is that products can cause tendon alošta to be weaker than autographs.
Despite their disadvantages, aloštípy still designs many situations. If the patient has several injuries, then there may not be enough tendons in their body to address each of them. In addition, autogenic grafts may be impossible if patient již had one or more previous tendon exchanges. With regard to severe tendon injuries, whether to use graft of tendons, depends on the extent of damage. Subsequent decisions on where to reap the graft is generally made by physicians and patients after a thorough discussion.
