Step 2. Extension is then made by an assistant, the surgeon grasps the leg above the ankle, and rotating the limb inwards and outwards, but without lifting it from the bed, guides the head into the acetabulum.
Here, as after dislocation backwards, a long splint should be worn on the limb for three weeks before the patient is allowed to move about at all.
Dislocation on to the Pubes.—The limb is easily moved at the hip, shortened, rotated outwards, and the head of the bone is felt in the groin.
The same apparatus is used in this as in the dislocation on the dorsum ilii. It is applied as follows:—
Step 1. The patient lies on his back (fig. 68), with his legs separated. The pelvic band is passed over the perinæum and pubes, and attached above the patient, in a line passing from the pelvis a little to his sound side. A double jack towel is slipped up the limb to the perinæum; the pulleys are fastened to the thigh above the knee and fixed, in the manner directed on page [106], to the wall below and external to the injured side of the body.

Step 2. Extension is then steadily made, while the surgeon watches the head getting free from the pubes, over the edge of which a second assistant slipping his neck through the doubled towel, raises the bone a little outwards. The surgeon in the meantime encourages the bone by rotation to enter the socket.
