So far as can be learned there is no history of post-natalaccident, nor of any similar condition in any other member ofthe family. Physically the child is normal except that the hands are al-ways pronated. If asked to accept a penny he does so withthe finger tips, not with the palm up. If one insists on drop-ping it into his hand, he flexes the forearm completely on the (3701 DISLOCATION OF THE HEAD OF EACH RADIUS. 371 arm and carries the hand over the shoulder, its dorsum down-ward, showing very plainly the lack of rotation. Flexion andextension of the forearm are complete and perfect. Rotationof the forearm is entirely wanting, and what little advancethat is made from pronation to supination is purely through theradio-carpal Fig. I.—Boy trying to grasp a stick so as to place the hands in complete supination. Examination of the elbows shows the external and internalcondyles and the olecranon normally situated; immediatelybeneath the articular surface of the external condyle is aroundish mass which can be traced into the radius, and which 372 IV.

The radial head is absent from its normal following the radius backward it can easily be noticed thatthere is a backward dislocation of its head and that the radialneck and shaft have curved themselves partly around and overthe ulna, allowing the lower end of the radius to lie internal tothe ulna as it normally is in full pronation. Supination is pre-vented by this locking of the radius about the ulna. The dis-located radial head on complete flexion of the forearm pro-jects very much like a second olecranon. There is no coales-ence of the radius and ul
