Dr. Chankov, what are the most common hip problems that could lead to hip replacement?

- In orthopedic practice, it has been proven that about 10% of hip replacement cases are due to aseptic necrosis. It is a pathological process that is the result of a violation of the dewing of a section of the head of the femur. Since bone is a living tissue, cutting off its blood supply leads to its gradual destruction and necessitates joint replacement.

What are the causes of aseptic necrosis?

- There are many theories as to what causes aseptic necrosis. Risk factors include: chemotherapy, alcoholism, steroid overuse, caisson disease, vascular compression, hypertension, vasculitis, arterial embolism and thrombosis, radiation damage, sickle cell anemia, and Gaucher disease. In some cases, the cause is idiopathic (unexplained). Rheumatoid arthritis and lupus are also common causes of aseptic necrosis.

What are the patient complaints and how is the problem diagnosed?

- In the early stages of the disease, no symptoms are observed, but as the disease progresses, pain appears. Initially, it appears only when loading (walking, running, etc.) on the affected joint, but over time it becomes constant and very strong, even in a state of rest. It can cause lameness and stiffness in the joint.

The time between the first symptoms and the destruction of the bone can vary from a few months to more than a year. When this process occurs, in most cases, standard operating methods only slow down the process of bone destruction.

The most accurate and earliest diagnosis is achieved with an MRI of the hip joint.

What is selective osteoinduction?

- Selective osteoinduction is an innovative operative method that largely prevents future hip arthroplasty. The method consists of three main steps: first - preparing a biological product from the patient's peripheral blood, second - placing a special fenestrated implant and third - injecting the biological product.

What are the advantages of selective osteoinduction over classical operative methods?

- Selective osteoinduction is a relatively new method that overcomes many of the disadvantages of other operative methods and has a very high success rate. I have been applying this method at Vita Hospital for more than a year with very good results. The method is minimally invasive, shortens the operative time, and blood loss and general operative risks are reduced to a minimum. Movement begins on the 1st postoperative day - much earlier than conventional surgery, and patients are fully capable of self-care.

In order to help everyone who has complaints related to aseptic necrosis, or simply doubts that they may have such a problem, we organize free examinations.

Free examinations for patients with diagnosed or suspected aseptic necrosis of the femoral head

MBAL "Vita" organizes free examinations for patients diagnosed with aseptic necrosis of the femoral head or suspicions of such. Examinations will be performed by Dr. Chanko Chankov on

March 11 - from 16:00 to 19:00

You can make an appointment for an examination by phone: 02/960 49 50 or 02/960 49 51.
