What is a dislocated shoulder?

Is the total dislocated joint venture between the humeral head and glenoid. It therefore produces the output of the humeral head of the joint.

When we speak of is partially dislocated subluxation.

Both may be accompanied by a fracture in the area but is a rare picture except the collapse suffered fracture of the humeral head to strike the rim of the glenoid when you leave.What is the shoulder joint?

It is the linker that build bone of the humerus to the scapula or shoulder, the humeral head, which is large and shaped like a sphere, articulates with the glenoid of the shoulder, a smaller pouch and in a shallow bowl. That makes it very mobile joint, with nearly 360 degree range of motion of the arm.

But it is also relatively consistent (the fit between the two sides of the joints is not perfect), so you need to increase between the two bones by a ring of fibrocartilage that surrounds the edge of the glenoid rim (labrum), in addition to stability which depends on muscles and ligaments.
