Varieties of Dislocation.—The thigh-bone I have seen dislocatedin four directions :—First, upwards, or upon the dorsum of the ilium;secondly, downwards, or into the foramen ovale; thirdly, backwardsand upwards, or into the ischiatic notch ; and, fourthly, forwards andupwards, or upon the body of the pubes. Besides these four, two otheranomalous dislocations have been described, of which we shall speakin the proper 30 DISLOCATION OF THE HIP-JOINT, SECTION II. DISLOCATION UPWARDS, OR ON THE DORSUM ILII. This dislocation is the most fre-quent of those which happen to thehip-joint: and the following are thesigns of its existence. Symptoms.—The dislocated limbis from one inch and a half to twoinches and a half shorter than theother, as will be seen by supportingthe patient in the erect positionand comparing the inner toe rests upon the tarsus ofthe other foot; the knee and footare turned inwards, and the kneeis a little advanced upon the an attempt is made to sepa-rate the leg from the other, it can-not be accomplished, for the limbis firmly fixed in its new situation,so far as regards its motion out-wards, although the thigh can beslightly bent across the other. Ifthe bone be not concealed by extravasation of blood, the head of it canbe perceived moving upon the dorsum ilii during rotation of the kneeinwards; and the
