Brief overview of the episode:

Avascular Necrosis is bone death due to poor or loss of blood supply. This most commonly affects the ends of long bones, femur, humerus and sometimes the carpal, metacarpal and tarsal bones.
Symptoms during the early stages are usual not noticeable. As the disease progresses pain, weakness and ROM loss are the most common signs. An x-ray is the clearest way to make a diagnosis.
In most cases trauma is the initial cause of avascular necrosis. There is also consistent evidence that long term cortico-steriod use is a risk factor.
Treatment is most often immobilization, with varying degrees of benefit. In most cases a joint replacement will be the final result.

Brief except from the episode:

Shoulder dislocation, it hurts. The most common cause is trauma, from a fall. The result is where the humerus (the upper arm bone), is no longer contacting the glenoid. Based on the joint configuration it is fairly easy to see why this happens. It is actually surprising this does not happen more often.
The shoulder joint is set up like a golf ball resting on a saucer that is tipped on it’s side. The saucer however, is the size of a golf tee. This is why there is a lot of mobility in the shoulder. It is also the reason why there can be a lot of instability.
Physical therapy can be a good way to help strengthen and stabilize the shoulder joint. Most people who come to physical therapy for a shoulder dislocation do so as a result of recurrent dislocation and are hoping to avoid surgery. Surgery is typically done to repair the labrum or to tighten up the joint capsule.
A lot of people recall the movie Lethal Weapon with Mel Gibson. We see him jam his shoulder into the wall to relocate it. This is 1 million percent the wrong way to try to relocate a shoulder. When a shoulder is dislocated the muscle around the shoulder go into spasm. The spasms prevent relocation. The goal is to try to get the individual with the dislocation to relax. If you can get the upper trapezius, the deltoid and the latissimus dorsi to stop spasming the shoulder will at times relocate on its own. DO NOT FORCE the shoulder to relocate.
Relocating a shoulder is difficult; take the individual to the hospital as soon as possible. Often time’s sedation is the only way to get an individual to relax and get the shoulder to relocate.
