On account of their economic importance and surgical interest, a study of the acute infections of the flexor tendon sheaths of the hand was undertaken at the Presbyterian Hospital over two years ago. A series of fifty-seven consecutive cases, observed from Jan. 1, 1916, to Jan. 1, 1923, has been analyzed. The series is presented, with the end-result in each case, observed for an average time of nearly one and one half years. These end-results are defined so that the reader may appreciate what have been considered as various degrees of success or failure. The method of treatment presented has been evolved as a result of lessons learned by experience. By means of a definite technic, to be described subsequently, we have been able to achieve far better results in our later cases than in our earlier ones.
