Previous to the last decade, torsion of the spermatic cord was considered rare. In 1930 Donovan1collected 163 cases from the literature, in 13 of which the patients were less than 1 year of age. He reported 3 additional cases in which the anomaly was observed in infants. Since that time over 200 cases have been added to the literature, and relatively the same percentage of infantile involvement has prevailed. Three recent cases of involvement before 1 year of age occurring in the Children's Surgical Service of Bellevue Hospital are reported in this paper. The Children's Surgical Service was organized in 1917 and consists of approximately 80 beds. Children from infancy to the age of 13 are admitted. As a search of the records of this service reveals only the 3 aforementioned cases, it is apparent that torsion of the spermatic cord is still relatively uncommon in infants. In
