Fibrous ankylosis may follow upon injury, especially dislocation or fracture implicating a joint, or it may result from any form of arthritis. It is often found between the patella and the trochlear surface of the femur in tuberculous disease of the knee.
Temporary luxation of the patella is a common affection of the horse and fixed luxation of this bone also occurs. As a matter of fact, in the horse, patellar luxation is the one frequent affection of this kind.
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.
The rock composing it is drilled everywhere by Pholades, the holes which they perforated having been afterwards filled with sand, and covered over when the newer beds were thrown down. The older formation is shown by its fossils to have accumulated in a deeper sea, and contains none of those littoral forms such as the limpet, Patella, found in the Red Crag.
There are worse things than a fractured patella I believe that's what you called the injury, Doctor Churchill."
I have thought that in fracture of the patella it would be peculiarly valuable, as it is so readily adjusted to all the inequalities of the knee joint. CASE SECOND. Jerome De , aged fifty-four years, native of France, single, was admitted to the Santa Clara County Hospital, July 20th, 1878.
Outward displacement is comparatively rare. The causes of "stifle out" may be described as follows: The patella or knee-cap rests on a pulley-like articular surface belonging to the inferior extremity of the thigh-bone. The external lip of this articular surface is smaller than the internal lip.
"But, Doctor Forester, what are we to do about father and mother? We can't tell them " "Tell them! No!" said Doctor Forester, with decision. "I wouldn't have your mother told under any consideration, so long as the girl does well. She would be back here on the next train and then we'd have something worse than a broken patella on our hands.
The first was a salt-pool lying in a depression on the second terrace, some one hundred and fifty feet above the sea. This pool contained living marine shells, identical with those now found along the shore. Among them were Fusus, Mytilus, Buccinum, Fissurella, Patella, and Voluta, all found in the same numeric relations as those in which they now exist upon the beach below.
"Surgeon Patella, of the Algerine," said Cuticle, in an ill-suppressed passion, abruptly turning round on the person addressed, "will you have the kindness to say whether you do not think that amputation is the only resource?"
