ThePenIsMyTier saidI'm glad to see I'm not the only one struggling with this shoulder thing!
Shoulder instability can be classified into two different types, dislocations and subluxations.
This happens when the head of the humerus completely pops out of the socket. The first few times this happens, it is usually with significant trauma (although some people can have these without any in injury at all). After that, it can get easier and easier for the joint to dislocate.
This is the feeling that the shoulder slips slightly out of socket, then immediately comes back in place. This often happens without any major trauma. Sometimes it happens in people who are very loose-jointed.
Orthopedic surgeons recommend conservative treatment and reserve surgery for people that are significantly impaired.
Strengthening the rotator cuff is the proven way to improve joint instability. The bodybuilding exercises like military presses do not build the rotators cuff. The overhead and behind head movements tend to make shoulder problems worse.
There are many web pages on the Net discussing rotator cuff exercises.
Here is a link to just one sitehttp://familydoctor.org/online/famdocen/home/healthy/physical/injuries/265.html
If many of your joints are lax, you should be evaluated by a physician to rule out a genetic disorder.
The most common problem is benign joint hypermobility syndrome. This tends to run in families. If someone has very lax joints he can be predisposed to subluxations and dislocations. When he is older, the chronically weak joints will develop osteoarthritis.
Althought rare, there are two genetic disorders that are not benign and cause lax joints.
The more common is Marfan's syndrome which is associated with aortic aneurysm's. Michael Phelps has Marfan's and has annual echocardiograms to check for aneurysms. His last check up was good.
The other problem is Ehlers Danlos syndrome. Guys with the very extreme form of this illness do videos on YouTube..not everyone with Ehlers Danlos is a rubber man
