Joint fusion, also known medically as arthrodesis, is usually the last resort for patients with severe joint arthrosis. Ankle joint fusion affects the ankle joint in the ankle area. The aim of this type of joint fusion is to relieve pain. However, complications can also occur. Arthrodesis is therefore the last resort in the treatment of osteoarthritis.
Here you will find further information as well as selected arthrodesis specialists and centers.
Ankle joint fusion (arthrodesis) is a surgical procedure that fixes the ankle joint so that it can no longer move. This is an extreme measure and therefore the last option for providing people with advanced ankle arthrosis with freedom from pain.
Ankle osteoarthritis, like any other form of osteoarthritis, is characterized by the destruction of joint cartilage. Patients in the late stages of the disease are unable to move as a result. Inflammation and joint effusions also cause severe pain. This makes any movement in the affected ankle joint impossible.
If it is not possible to replace the damaged joint with an endoprosthesis, the last option is arthrodesis. The joint fusion procedure was originally developed for these patients.
In principle, however, the procedure can be performed on any large joint in the body(shoulder, hip, knee, wrist, ankle).
The specialist decides who is eligible for such an operation.

In the medical history and physical examination, doctors first examine
Misalignments and other joint changes are assessed to determine whether surgical correction is possible and indicated.
In order to visualize the joint surfaces, an X-ray is usually requested. However, magnetic resonance imaging(MRI) and computer tomography(CT) also help to visualize the joints involved.
With the help of arthroscopy, doctors are able to look inside the joint in question and, for example, smooth joint surfaces or begin minor clean-up work.
The procedure is usually performed openly via a large tissue incision. In some cases, however, a minimally invasive arthroscopy is also possible.
As a rule, joint fusion procedures always follow a similar pattern.
In the joint, the surgeon removes and straightens the damaged joint surfaces and bone parts that form the joint.
The two bone ends are then firmly joined together using osteosynthesis, similar to fracture treatment. To do this, the surgeon uses
After the procedure, the joint is closed again and immobilized for some time.
Depending on the joint damage, ankle fusion is a very complicated procedure. This can result in damage to the soft tissues of the foot, such as
Wound pain is a frequent companion in the days following the operation. However, this can be easily treated with suitable painkillers. The joint is often immobilized with a splint or other aids for the healing period.
The operation can also damage neighboring structures and tissue. This can lead to
can occur. Secondary arthrosis is also possible if neighboring joints are damaged.
Ankle arthrodesis is usually performed openly. There is therefore a risk of wound infections, which usually lead to a longer healing process. A wound infection can also promote wound healing disorders.
The prognosis for ankle fusion depends primarily on whether complications occur. Infections and misalignments in the joint are rare, but possible. They can lead to a delay in the healing process.
In addition, widespread comorbidities influence the prognosis for arthrodesis. These include, for example
All of these factors, which are particularly prevalent in old age, impair the long-term success of the operation.
Specialist clinics and experts are needed to treat advanced ankle arthrosis. Specialists in foot surgery and joint specialists as well as hospital centers certified in endoprosthetics are your contacts here.
