Pseudarthrosis, also known as pseudarthrosis, is a rare complication of bone fractures. It occurs due to non-union of bones in the fracture zone and leads to the formation of mobility along the bone. Instead of bone tissue, connective and cartilaginous tissue develops in the fracture zone. This results in the formation of a false joint, which is not a true joint because it lacks normal articular cartilage and synovium.
The etiology of pseudarthrosis is associated with various factors. This may be an infection, a disorder of the blood supply to the bone, mobility of fragments, as well as premature removal of the plaster cast. Rarely, false joints can be congenital, caused by a disorder of intrauterine bone development.
Symptoms of a pseudarthrosis can vary depending on where it is located and how much mobility it has. Most often, patients complain of pain in the area of the pseudarthrosis, impaired support function of the leg or decreased function of the arm, as well as curvature of the limb at the level of the pseudarthrosis. However, if the pseudarthrosis is tight, there may be no pain or dysfunction.
X-ray examination is used to diagnose pseudarthrosis. An x-ray can show the absence of bone tissue in the fracture zone and the presence of connective and cartilaginous tissue.
Treatment of a pseudarthrosis depends on its degree of mobility and the presence of symptoms. For pain and loss of function, surgical treatment is indicated. The surgery may involve bone immobilization, the use of an implant, or a bone graft. If surgical treatment is not possible, then patients may be prescribed orthopedic devices.
Prevention of pseudarthrosis involves strict adherence to the timing of immobilization after a fracture. It is also important to avoid additional injuries and overloads in the fracture area during the recovery period.
In conclusion, pseudarthrosis is a rare complication of bone fractures that can lead to pain and loss of limb function. To diagnose and treat pseudarthrosis, timely consultation with a specialist is necessary. It is also important to follow preventive measures to prevent the development of this complication.
