The dislocated limb is advanced before the other, andthe toes generally point directly forward, but they may incline either 1 Lente, New York Journ. Med., November, 1850, p. 314. 14 DISLOCATIONS OF THE THIGH outward or inward. The hip is flattened or depressed; the long adduc-tors are felt tense upon the inside of the limb ; the trochanter majoris less prominent than upon the opposite side ; and the head of the bone FlCr. 4(i0. ;? fffip. Relations of the ilio-femoral ligament to the thyroid dislocation. (From Bigelow.) may sometimes be felt in its new position. The apparent lengthening ofthe limb alone is sufficient to distinguish this accident from a fracture ofthe neck. I have said apparent lengthening, because in the position in which thelimb is found, it is difficult to make an accurate relative measurement of the twolimbs ; and, indeed, Rivington,1 of the London Hospital, could not in a caseseen by him recognize any shortening, and in his experiments upon the cadaverhe obtained a similar result. Holmes,2 also, in a clinical lecture has stated thatthe lengthening is less marked in proportion as the abduction and outward rota-tion are greater. In some cases the position of the head of the femur may be recognizedby a rectal examination ; or, in the case of females by a vaginal exami-nation. The flexion and abduction are due in some measure to the ten-sion of the pso
