1. Twenty-four cases of excision of the lunate bone in Kienböck's disease have been reviewed.

2. In general, the results have been favourable, with 88 per cent excellent or good and 12 per cent fair or poor.

3. Abnormal contact between the triquetrum and the styloid process of the ulna appeared in many cases, but this contact did not appear to prejudice the results.

4. Excision after prolonged symptoms of the disease gave disappointing results.
