By a recent experience my attention has been called to benefits that may be derived in syringomyelia from surgical intervention. Looking over the literature I was surprised to find no references of American authorship to resort to operation for this condition. As a matter of fact, the first recorded operation for syringomyelia is contained in an article by Puussepp,1 who related his operative experience in two cases. Only four other pertinent articles have appeared since Puussepp's original contribution; one by the same author,2 one by Förster,3 one by Schmieden,4 and one by Oppel.5 I shall not review these articles in detail. Suffice it to say that Puussepp has operated on four patients with manifest improvement; Schmieden on one patient with definite improvement in movement of arm and leg and of sensation; Oppel performed seven operations on six patients with results varying from negative to brilliant.
