knee-joints were partially flexed, and on attempting to straighten the limb, he complained of great pain at the upper part of the thigh internally, the tendons of the long flexor

muscles of the knee becoming very tense at the same time. There was a marked fulness and hardness near the obturator foramen, with a corresponding depression on the outer side of the limb. The great trochanter was also from one and a half to two inches below its normal position. From the above symptoms I diagnosed the case as one of " dislocation into the thyroid foramen." On the following morning he was placed under the influence of chloroform, and with the assistance of Surgeon-Major Gore and Dr. Greene I proceeded to reduce the dislocation. A folded^ sheet was passed round the opposite thigh near the groin, with which counter-extension was made. The ordinary thigh-piece having been fastened on just above the left knee, the limb was drawn strongly downwards so as to disengage the head of the bone ; the knee being at the same time rotated inwards, while the head of the bone was drawn directly outwards by a folded napkin. In a short time it returned into the acetabulum with a loud snap. The thighs were then fastened together with a broad bandage, and he was ordered to keep perfectly quiet in bed. Dislocation of the hip is very rarely seen in army practice, being much more frequent amongst farm labourers, and those whose occupation leads them to work at some height above the ground. The dislocation backwards into the sciatic notch is considered the most difficult of reduction. In a case which I saw in 1872, the operation proved very tedious and troublesome, although performed by two of the leading Dublin Surgeons, viz. the. late Mr. Adams and Mr. W. Stokes, six weeks had however elapsed from the date of the injury. In the present case the reduction was rendered very easy by the administration of chloroform, which relaxed all the muscles, and did away with the struggling of the patient. There was also no delay in seeking medical advice. The pain referred to the upper third of the thigh, was probably due to pressure upon the anterior crural or obturator nerves.
