Necrosis of which carpal bone is most commonly associated with Keinbock's disease?

Keinbock's disease is primarily characterized by avascular necrosis of the lunate bone in the wrist. This condition often results from impaired blood supply to the lunate, leading to its degeneration. The lunate is one of the central bones in the wrist and plays a crucial role in the mechanics of wrist movement.

In Keinbock's disease, the lack of adequate blood flow can cause the lunate to harden and eventually collapse, resulting in pain, swelling, and reduced wrist function. As the disease progresses, it can lead to further complications, including the development of arthritis in the wrist joint due to the misalignment and degeneration of the carpal structures.

The other carpal bones mentioned do not typically associate with Keinbock's disease in the same way. While conditions can lead to necrosis in other carpal bones, Keinbock's specifically targets the lunate, making it the most recognized and studied bone in relation to this condition.
