VASCULARİZED BONE TRANSPLANTATİON
Our patients suffer from bone loss due to some reasons. Bone loss is sometimes due to loss of bone content (osteonecrosis) due to the deterioration of the circulation of the bone, sometimes due to defects that occur due to non-union of the broken bone after the fracture (pseudoarthrosis or nonunion), sometimes as a result of the treatment of bone tumors with tumors removed by us. It may occur as a result of the defects created by the bone, and sometimes as a result of the defects created by us as a result of the removal of bone inflammation (osteomyelitis).
The bone tissue to be taken from the patient can be obtained from different body parts with or without vessels, depending on the size and characteristics of the defect to be applied. For example, for a defect formed as a result of removing a benign tumor from the finger bones, a 1 cm incision from the elbow region is sufficient, while for larger bone defects. vascular bone tissue from different body parts will be needed.
In vascular bone transplantation, the bone tissue taken is transported to the defective area with its vein. This means that the transferred bone is living bone. This process can be done by removing a bone section with its vein from a region close to the defective area and turning it into the defective area, or the bone taken from a region far from the defective area with its vein. It can also be done by suturing a vein in the area of the defect under a microscope.
There are many advantages of carrying the bone alive with its vein. In order for the treatment to be successful in bone transplants, it is expected that the transferred bone will fuse to the applied area. Vascular (live) bone transplantation increases the chance of success of this union, that is, the treatment, especially in long bone defects larger than 8 cm, vascular bone transplantation It is very important for the success of the treatment.
A vascular tissue reduces the risk of infection as it allows the body defense cells and the antibiotics we give to the patient to reach this area. This situation increases the success of the treatment, especially in bone transplants for the treatment of bone infection (osteomyelitis).
Another common area of use for vascular bone transplant surgeries is avascular necrosis (loss of bone) in which bone circulation is impaired. This may occur in small bones in the wrist (kienbock-lunatum avascular necrosis) or in the hip (femoral head avascular necrosis). Because it causes vascular bone transplantation to the damaged area, it is the most appropriate treatment for patients who can often be applied for the cause of the disease.
Although vascular bone transplants give very satisfactory results in suitable patients, a team with advanced microsurgery experience is required to perform these surgeries.
