The cases constituting the basis of this report were studied at the U. S. Army Base Hospital, Camp Merritt, N. J., during the period from December, 1918, to March, 1919. As this institution evacuated the wounded to hospitals of the interior, the treatment given these patients during their brief stay was of a temporary nonsurgical nature. As a consequence, no therapeutic deductions were made from the treatment applied to this group of cases. The tables appended (Tables 1, 2 and 3) give a detailed analysis of the cases.
The 415 instances occurred in 328 patients, 76 of whom had two or more lesions. Of these multiple injuries, which occur with much greater frequency in lesions of the upper extremities, the commonest combinations are analyzed in Table 2.
These cases have been examined at this hospital, on an average of from three to five months after the original injury was sustained;
