1. A series of 110 cases of trochanteric fractures treated by internal fixation with the Capener-Neufeld nail-plate is presented. The age incidence, mortality, complications and functional results are discussed in detail. 2. The results are compared with those of two series of cases treated conservatively: a) 101 cases treated conservatively in hospital; b) 25 cases sent home by reason of shortage of hospital beds. 3. From a consideration of these three series, and from study of similar series of cases reported in the literature, it is concluded that routine operative treatment of trochanteric fractures offers the advantages of lowered mortality, improved function, economy of hospital beds, and greater comfort and mobility of the patient. 4. Certain points in the management of cases during the operation and in the convalescent period are discussed.
