Thanks for writing in.
Kienbock's disease with high ESR
and total leucocyte count might indicate some kind of inflammatory process going on there. It can be due to Rheumatoid arthritis
1. Is there any other joint involvement - particularly small joints of hand with/without swelling?
2. Is there low grade fever
in evening? loss of appetite or weight?
Discuss with your doctor. He might order few additional blood tests - CRP, ASO titre, RA factor, S.Uric acid.
Rheumatoid arthritis / Inflammatory arthropathy
respond well to oral medications. But if the Kienbock's disease is severe, then she needs surgical removal of the lunate bone
Hope i have answered your query. Feel free to ask any doubts.
Wish your mom a good health.
