The Brittain V-arthrodesis is a satisfactory procedure for osteoarthritis of the hip. It is particularly suitable for elderly patients when the range of hip flexion is less than 60 degrees. If the four deaths are excluded, two-thirds of the patients secured a sound bony fusion. This occurs slowly. All but one of the patients who survived for three years or more after operation had a sound bony fusion. It is evident that the operation, given time, yields a high rate of sound bony fusion in the hip. It seems likely that use of the McLaughlin nail plate would prevent the one serious complication, namely fracture of the shaft of the femur through or immediately below the drill hole made for the fibular graft.
