shoulder

 [shōl´der]
the area around the glenohumeral joint, the large ball-and-socket joint where the humerus joins the scapula. The smooth, rounded head of the humerus rests against the socket in the scapula. The joint is covered by a tough, flexible protective capsule and is heavily reinforced by ligaments that stretch across the joint. The ends of the bones where they meet at the joint are covered with a layer of cartilage that reduces friction and absorbs shock. A thin membrane, the synovial membrane, lines the socket and lubricates the joint with synovia. Further cushioning and lubrication are provided by fluid-filled sacs called bursae. Disorders of the shoulder include bursitis and dislocation.

Patient discussion about shoulder

Q. how can i solve my back and shoulder problems? also how can i get raid of my eye bugs?

A. krando,
many thanks i will try those tips you just give me...wish you a wonderful and safe and sound newly year...

Q. shoulder and neck strain and pain I have a terrible shoulder and neck pain and i keep cracking my neck muscles to release pressure. I get temporary relief with tylenol but after few hrs the pain and strain starts again.Any ideas?

A. A mellow exercise and streching on a regular basis is the best way to release a sore back and muscles in general, including your neck. You should try that plus applying local warm temperature (for example a warm pillow)around your neck. If that doesn't work then other anti-inflammatory drugs that you either apply as a cream or take as a pill can help you.

Q. How do I gain range of motion after shoulder surgery I'm 31 years old and had a shoulder replacment last year. I still don't know why my joint gave out and 4 Orthopedic Surgeons couldn't tell me either. I have limited Range of Motion and the Dr. seems to think that because of my "age" I was less likley to get full range back. I refuse to believe that, does anyone have any suggestions on how to gain ROM back?

A. i guess you go to physiotherapy no?
that is their job. to give you range of motion after injuries, surgeries ect. they'll give you exercises specially for your condition. when i had an accident i broke my leg hip and i needed 2 months of physiotherapy that helped very much.
