1. A new technique for fusion of the elbow joint is described. It consists of the use of a mass of cancellous bone, the olecranon, with its soft- tissue attachments intact, to bridge the joint from humerus to ulna, and is modeled from the method of hip fusion described by Dr. Russell A. Hibbs.
2. The reports are given of three cases of tuberculosis of the elbow joint treated by fusion.
