What is the prevalence of Kienbock Disease?

Kienbock Disease, also known as avascular necrosis of the lunate, is a rare condition affecting the wrist joint. It occurs when the blood supply to the lunate bone in the wrist is disrupted, leading to its gradual deterioration and potential collapse.

The prevalence of Kienbock Disease is relatively low, making it a rare condition. Exact statistics on its occurrence are limited, but it is estimated to affect approximately 3.5 to 5.8 individuals per 100,000 population. The condition typically affects individuals between the ages of 20 and 40, with a higher incidence in males than females.

While the exact cause of Kienbock Disease is not fully understood, several factors may contribute to its development, including trauma, repetitive stress, and anatomical variations in the blood supply to the lunate bone. Early diagnosis is crucial for effective treatment, which may involve conservative measures such as immobilization, pain management, and physical therapy. In more advanced cases, surgical interventions like bone grafting or joint replacement may be necessary.

Overall, although Kienbock Disease is a rare condition, it can significantly impact the wrist joint and the individual's quality of life. Timely diagnosis and appropriate management can help alleviate symptoms and prevent further progression of the disease.
