Depends where it's dislocated - whether at the shoulder joint, or elbow.
Shoulder is normally very painful, should be only attempted under sedation (patient not doctor!) and requires X-rays afterwards to confirm it's correctly in place.
Elbow can be popped in by supporting the lower arm and carefully rocking the wrist from side to side with a little push.
Take him to a veterinarian. Popping joints back in is not a job for amateurs. (A distant relative of mine dislocated his shoulder playing soccer. His teammates tried to pop it back in. They ruptured the artery and he lost his arm.) By letting the vet do it.
It is not safe to attempt to pop an arm back into its socket without medical training. You should seek immediate medical attention if you suspect a dislocated arm to prevent further injury. A healthcare professional will be able to safely relocate the joint.
The shoulder is the most common location for arm dislocations, followed by the elbow and wrist. Shoulder dislocations occur due to trauma or overextension of the joint, causing the ball of the upper arm bone to pop out of the shoulder socket.
These are difficult to find but they do pop up on EBay occasionally. Search for "socket 775 cover" or "socket 775 protector" in "Computing".
There is no evidence to suggest that Anne Frank was able to pop her arm out of its socket. Anne Frank's diary, where she documented her experiences during World War II, does not mention anything like this happening.
Ball and socket joint The arm movement is possible because of ball and socket joint.
Pop the cap out of the center of the crank arm and tighten with a 14mm socket. Replace cap when done.
If the joint between your arm and shoulder was not a ball and socket joint, you could not be able to move your arm. Ball and socket joints allow you to move in most directions. Because of this, you can move your arm up, down, side to side, front and back, and around in a circle. The ball and socket joint is one of the four major kinds of movable joints. (The four major joints are ball and socket joints, gliding joints, hinge joints, and pivotal joints in case you didn't know.)
A scapular is that chicken wing on your back if your wondering. to pop a scapular you fold theyr arm like they are making a muscle and put theyre arm behind theyre back and push it behind theyre back and keep pushing as hard as you can and eventually it will pop. It is better to do this but in a sudden sharp push this will be more effective than constant pressure.
Ball-and-socket joints in the shoulder allow you to perform arm circles, providing a wide range of motion in different directions. These joints allow for the circular movement of the arm around the shoulder socket.
Ball-and-Socket, the shoulder's cartilage being the socket and the arm's ending being the ball.
