With the patella disarticulated in this manner, the action of the quapriceps femoral group of muscles has no effect on the stifle joint and, therefore, flexion of this articulation occurs as soon as the subject attempts to sustain weight and the leg collapses unless weight is at once taken up by the other member if sound. As a rule, the reduction of this form of luxation is not difficult.
He was not able to learn the particulars in the last case, but the raftsman came too close to a bear that was at bay, and it broke through the dogs, rushed at and overthrew him, then lying on him, it bit him deeply in the thigh, through the femoral artery, so that he speedily bled to death.
Experience shows that ligation of the vein, or even the removal of a portion of it, is not necessarily followed by gangrene. The risk of gangrene is diminished by a course of digital compression of the femoral artery, before operating on the aneurysm. Aneurysmal varix is sometimes met with in the region of the popliteal space.
The left hip was greatly distorted, not only in the direction of flexion, but there was also twisting of the femoral neck, simulating dislocation. This patient was also operated on in the same manner as the preceding one. Relative to anomalous increase or hypertrophy of the bones of the extremities, Fischer shows that an increase in the length of bone may follow slight injuries.
The differential diagnosis is to be made from abscess, bursal cyst, enlarged glands, and sarcoma, especially pulsating sarcoma of one of the bones entering into the knee joint. The choice of operation lies between ligation of the femoral artery in Hunter's canal, and Matas' operation of aneurysmo-arteriorrhaphy.
These pretended thigh-bones of giants were carried to the port of Cumana, where I sought for them in vain; but from the analogy of some fossil bones which I brought from other parts of South America, and which have been carefully examined by M. Cuvier, it is probable that the gigantic femoral bones of Cumanacoa belonged to elephants of a species now extinct. Jefferson.
The limb having been rendered bloodless, existing sinuses are enlarged, but if these are inconveniently situated for example, in the centre of the popliteal space in necrosis of the femoral trigone it is better to make a fresh wound down to the bone on that aspect of the limb which affords best access, and which entails the least injury of the soft parts.
#Subcutaneous rupture# of veins occur most frequently in association with fractures and in the reduction of dislocations. The veins most commonly ruptured are the popliteal, the axillary, the femoral, and the subclavian.
The hog's pulse can easily be taken from the femoral artery on the internal region of the thigh. The artery crosses this region obliquely and is quite superficial toward its anterior and lower portion. The dog's pulse is usually taken from the brachial artery. The pulse wave can be readily felt by resting the fingers over the inner region of the arm and just above the elbow.
Since the femoral nerve supplies the quadriceps femoris muscles, it follows that when the psoic portion of this nerve becomes diseased, the stifle loses its support, and in a unilateral involvement when the subject attempts to walk on the affected member, the stifle sinks down for want of support and the leg collapses unless weight is caught up with the other leg.
