Shoulder Joint, Dislocation of:

Symptoms: Lameness; pain at the seat of injury, which is increased by putting leg forward; and some slight swelling, and the leg is perceptibly shortened. When there is any difficulty in diagnosing the case, all doubt is removed by making the dog stand evenly on both fore legs and comparing the sound shoulder with the injured one.

Treatment: In all cases I have seen of dislocation of the shoulder joint the head of the shoulder bone, which fits in a cup at the bottom of the blade bone, shoots upwards—of course only to a slight extent, as the bone is held in its position by strong muscles and tendons as well as by the capsule of the joint. Chloroform having been given, an attendant must hold the dog firmly by clasping his hands between the fore legs in front of the chest, or by fixing a towel in a similar position; and then the operator, seizing the paw with one hand, must pull the limb in a forward and downward direction, and at the same time with the fingers of the other hand press the head of the shoulder bone into its position. It is well afterwards to put a wide bandaging on round the chest over the shoulder joint, and keep the dog quiet for a few days.

Hock, Dislocation of:

This does not often occur except in conjunction with fracture at this part.

Symptoms: The dislocation occurs generally sideways, and may be either outwards or inwards, the foot being placed almost at right angles. The joint quickly swells, and is very painful.

Treatment: The reduction is carried out in a similar way as advised for reducing a dislocated elbow; afterwards the same kind of splints as recommended for treating fracture of the tibia are to be applied with bandages, and should be allowed to remain on for at least three or four weeks, and even after this it may be necessary to support the joint with a few strips of plaister for a time.

Patella, Dislocation of:

Symptoms: The patella is a small bone situated in front of the stifle joint, and is more liable to dislocation than any other part, especially in small dogs. With some dogs it is constantly slipping out of its place when running along, and then after a few steps it goes back again of its own accord. The bone almost always becomes displaced towards the inside of the leg, the dog in some cases being unable to put his foot to the ground; if he does attempt to put any weight on the leg, the stifle joint bends outwards. There is little or no pain caused by this dislocation.
