useful, especially when aided by a support, and in young patients a gradual and great improvement may take place.

Passive flail joints which are useless on account of great muscular wasting.

5. Injuries to the ulnar nerve with resulting interference with motion, sensation and nutrition.

Dr. E. R. GREGG: These photopraphs illustrate the case. These radiographs taken three months after operation, show the line of section through the humerus, radius and ulna with some of the new callus, the bone formation. This (Fig. 1) is in the extended position, here in the flexed (Fig. 2). These photographs or radiographs (Figs. 3 and 4), taken ten months after the operation, show the contraction of the joint, that is, of the soft parts, muscles and ail, making a new joint, and even here you see the articular fascets worn by the resected radius and ulna. There (Fig. 1) is a radiograp taken three months after operation. Here (Fig. 3) is a radiograph taken ten months after operation. You can see the straight line across all three bones as produced by the saw. There is, as you see, a diminution of space between the forearm and the arm, and what is almost a new joint. Here we have a photograph of the patient himself, and what he can do with that arm. Here (Fig. 5) he holds his arm out straight. Here (Fig. 6) you have him holding one of those oxygen tanks which weighs 6 pounds and 13 ounces. He is not able to hold that absolutely straight. He holds it flexed because the weight is too much for the elbow. He has every motion he had before (Figs. 7 and 8), but not quite the strength in his elbow he had before the operation. That is one case which we may count fairly successful. The other one is a case of failure functionally, at present a least. Here (Fig. 9) is a radiograph of the fracture, the radius and ulna below the fracture here. I would not attempt to count the pieces. It was a compound comminuted fracture. Here is the same case after admission to the hospital. This (Fig. 10) shows all the fragments removed, and, of course, the line was already made for us. We have no satisfactory result here. Here is a little string of callus and ossification extending down. It shows rather prettily the formation of new bone.

The only thing I think of saying in closing the discussion is to call attention to the necessity of obtaining in these cases an elbow joint that is successful functionally, and it seems to me from a very limited experience that attention should be called to the fact that one is more apt to err on the side of removing too little bone.
