Kienböck's disease is an osteonecrotic lesion of the upper surface of the head of the lunate bone, most often found in men aged 20 to 40 years. This pathology is characterized by a violation of the blood supply to the bone, which causes its destruction and associated pain, swelling and limited mobility in the wrist. The main cause of the disease is considered to be trauma or microtrauma to the wrist, but other factors contributing to the development of the disease are also noted. In advanced cases, the disease can lead to arthrosis of the wrist joint, which significantly worsens the patient's quality of life.
History of the disease and interesting historical facts
Kienböck's disease was first described in 1910 by the Swiss surgeon Rudolf Kienböck, after whom it was named. He studied the clinical manifestations of this condition in detail and suggested that its causes could be both injuries and professional stress. Since then, a large amount of data has been accumulated in medical literature, allowing us to expand our understanding of the mechanism of the disease and develop modern methods of diagnosis and treatment. Interestingly, in the early stages of the disease, Kienböck used conservative treatment methods, such as limb immobilization, which in some cases made it possible to avoid surgical intervention.
Epidemiology
Epidemiological studies show that Kienböck's disease occurs with a frequency of about 1 in 10,000 people per year. Men are most susceptible to the disease, accounting for about 70% of all registered cases. There is data on risk groups, which include people engaged in physical labor with high injury risks, as well as athletes who work with high-activity loads on the wrist. Studies show that the disease develops most often between the ages of 20 and 30, but the disease can also occur in young people.
Genetic predisposition to this disease
Genetic studies have not revealed a strict heredity of Kienböck's disease, but some studies indicate a possible predisposition. Mutations in genes responsible for the processes of osteogenesis and vascular regeneration can contribute to a decrease in the quality of blood supply to the lunate bone. In particular, some mutations in the MMP (matrix metalloproteinases) and VEGF (vascular endothelial growth factor) genes can affect the "vulnerability" of the bone to ischemia. However, individual genetic predisposition requires further study.
Risk factors for the development of this disease
Risk factors for Kienböck's disease can be divided into physical and chemical. Physical factors include:
- Wrist injuries, including fractures and dislocations.
- Frequent performance of monotonous movements, for example, when working at a computer or playing sports.
- Age-related changes leading to deterioration of blood circulation.
Chemical factors include:
- Professional exposure to chemicals that promote bone destruction.
- Alcohol consumption, which impairs tissue nutrition.
In addition, additional risk factors include the presence of endocrine diseases, such as diabetes, as they can negatively affect the condition of blood vessels.
Diagnosis of this disease
Diagnosis of Kienböck's disease includes several stages:
- Main symptoms: pain in the wrist area, decreased mobility, swelling.
- Laboratory tests: A complete blood count may reveal inflammatory changes.
- Radiological examinations: X-ray and MRI are the main methods that allow visualization of areas of necrosis.
- Other diagnostic tests: Arthroscopy can be used to visualize damage in the joint cavity.
- Differential diagnosis includes exclusion of other pathologies such as osteoarthritis or osteomalacia.
Treatment
Treatment of Kienböck's disease can be either conservative or surgical.
- General treatment: includes immobilization of the limb with a plaster cast.
- Pharmacological treatment: Nonsteroidal anti-inflammatory drugs (NSAIDs) are used to relieve pain.
- Surgical treatment: may include osteotomy or bone grafting in cases where conservative measures fail.
- Other treatments: Physical therapy and massage may be helpful in restoring wrist function.
List of medications used to treat this disease
Since Kienböck's disease requires an individual approach, the list of frequently used medications may include:
- Ibuprofen
- diclofenac
- Celecoxib
- Paracetamol
- Drugs to improve blood circulation (eg, pentoxifylline)
Disease monitoring
Disease monitoring is carried out to observe the dynamics of clinical manifestations and the effectiveness of prescribed therapy.
- Monitoring steps include regular check-ups, X-rays and MRIs.
- The prognosis of the disease depends on the stage at which medical care is sought and the degree of bone necrosis.
- Complications can range from limited mobility to progressive arthrosis, which significantly worsens the quality of life of patients.
Age-related features of the disease
In children and adolescents, Kienböck's disease is less common, and the disease is usually compensated for by the high reparative capacity of the tissue. In adults, especially those aged 30-50 years, the disease can lead to more severe consequences, including the need for surgical intervention. In older people, the disease is often accompanied by comorbidities, a decrease in general health and a short recovery period.

Advice from Dr. Oleg Korzhikov
Dr. Oleg Korzhikov recommends paying attention to the following aspects:
- If you have pain in your wrist, do not delay in seeing a doctor.
- Pay attention to your posture and proper distribution of loads on your wrist while working.
- Perform exercises regularly to strengthen your wrist muscles.
- If you have a predisposition to joint diseases, you need to be monitored by a specialist.
- Don't forget about the importance of a balanced diet, vitamins and minerals needed for healthy bones.
