1. Sixty myelographs have been obtained in severe traction injuries of the brachial plexus.

2. Seventy-eight traumatic meningoceles were outlined.

3. Multiple meningoceles indicate a gloomy prognosis.

4. In forty patients the results were compared with those obtained with the "axon reflex."

5. Myelography is a valuable aid in obtaining an early prognosis but the results must be correlated with the clinical picture.

1. Three cases of fatty infiltration of the median nerve are reported.

2. One patient had symptoms of median nerve compression.

3. The intimate association of fibro-fatty tissue within the nerve precludes enucleation of the swelling.

1 . Thirty-six patients with complete irrecoverable brachial plexus lesions have been studied.

2. Function has been compared after 1) arthrodesis of the shoulder with amputation through the arm, 2) so-called reconstructive procedures, and 3) no operative treatment.

3. The results of reconstructive operations have been so disappointing that we believe that this type of treatment should be abandoned.

4. Amputation-arthrodesis offers a better functional result than either reconstruction or no operation. Its value depends to a considerable extent on the manual dexterity of the patient.

5. A clerical worker who is not mechanically minded is less likely to use an artificial limb, and in this type of patient operation is perhaps best avoided.
