This is observed chiefly in chronic disease of pyogenic or tuberculous origin, and is usually attended with the formation of abscesses outside the joint. Ulceration of cartilage and caries of the articular surfaces are common accompaniments of the more serious and progressive forms of joint disease, especially those of bacterial origin.
Again, in Spelerpes rubra, where almost vertically ascending articular processes above are repeated by almost vertically descending articular processes below. Also in the axolotl, where there are douple pits, placed side by side, not only superiorly but at the same time inferiorly. This kind of homology is also explained by Mr.
Now, if you have ever prepared bones for a museum, as I have, you will remember the extreme care that is necessary in disarticulating joints to avoid disfiguring the articular ends of the bones with cuts and scratches." "Then you think that the person who dismembered this body must have had some anatomical knowledge and skill?" "That is what has been suggested. The suggestion is not mine."
But where luxation of phalanges accompanies sprain, reposition and immobilization are necessary that is if cases are thought likely to benefit by any treatment. Luxations Dislocations. Luxation or dislocation is a condition where the normal relation between articular ends of bones has been deranged to the extent that partial or complete loss of function results.
Nature, which so fashioned her elbows that she cannot throw a stone at a hen in the way in which a stone properly should be thrown at a hen, made suitable atonement for this articular oversight by endowing her joints with the facile knack of turning on exactly the right angle, with never danger of sprain or dislocation, for the subjugation of a back-latching frock.
On the occasion of our visit there were in the infirmary 7 men laid up: 1 with itch, 1 with diarrhoea, 1 with neuralgia, 1 with an abscess in the neck, 1 with articular rheumatism, and 1 with gastritis. A prisoner who had been trepanned by the doctors on account of damage done to his skull before his capture, was gradually recovering the power of motion and his normal sensibility.
The animal was destroyed and on autopsy the head of the femur found to be contained within a false articular cavity situated about four inches above the acetabulum. In Dr. Lusk's case as he states it, the following symptoms were presented: "Limb shortened and fixed in a position of adduction.
The scapula resembles that of the cetacean Hyperoodon, but the supra- spinous fossa is larger and more seal-like; as is the humerus, which differs from that of the Cetacea in presenting true articular surfaces for the free jointing of the bones of the fore-arm.
For several months a woman had suffered from an ulcer of the middle finger of the right hand, in consequence of a whitlow; there was loss of the 3d phalanx, and the whole of the articular surface and part of the compact bony structure of the 2d. On examining the sore, Ormangey saw a bony sequestrum which appeared to keep it open.
Poncet hastened a cure in a case of necrosis with partial destruction of the periosteum by inserting grafts taken from the bones of a dead infant and from a kid. Ricketts speaks of bone-grafting and the use of ivory, and remarks that Poncet of Lyons restored a tibia in nine months by grafting to the superior articular surface.
