Which condition is described as avascular necrosis of the lunate?

Kienbock's Disease is specifically characterized by avascular necrosis of the lunate bone in the wrist. This condition occurs when the blood supply to the lunate is interrupted, leading to bone cell death and subsequent collapse of the bone. Patients often present with wrist pain, swelling, and limited range of motion. The exact cause of Kienbock's Disease is not fully understood but may be associated with factors such as repetitive trauma or anatomical variations.

Understanding this condition is important for orthopedic technologists because it highlights the significance of early diagnosis and appropriate management strategies. While the other conditions listed involve injuries or disorders affecting the hand and wrist, they do not specifically pertain to avascular necrosis of the lunate.
