For my STEAM project I chose to focus on Kienbock’s disease. Kienbock’s disease, also known as avascular necrosis of the wrist, is a condition in which the lunate loses blood supply, and it leads to the death of the lunate. There are four stages to Kienbock’s disease and my project shows the progression of each stage with a playdoh model. During the first stage, the blood supply to the lunate has been disrupted but x-rays still appear normal or suggest a fracture. Stage two is when the lack of blood supply to the lunate begins to cause sclerosis of the bone and x-rays will begin to show bright areas located on the lunate, indicating the death of the bone has begun. Stage three is when the lunate has died, starts to collapse, and the surrounding bones may begin to shift to different areas of the writs, usually, it is the most noticeable in the capitate. Stage four, the final stage of Kienbock’s disease, is when the other bones located in the wrist start to show signs of deterioration, and the writs may become arthritic.
