Shoulder Replacement

Shoulder Instability Causes and Treatment

The shoulder joint possesses a wider range of motion as compared to any other joint in the human body. But this mobility comes with a price – less stability.

This article shares all you need to know about shoulder instability, its causes and treatment options.

Shoulder Instability

Shoulder instability is a condition affecting the GH or Glenohumeral joint of your shoulder. If you are wondering what it means, the GH joint is where the collar bone, shoulder blade and the upper arm bone come together. When the tissue holding the upper arm bone in place fails to keep the bone in place, it causes shoulder instability.

The GH joint is a ball-and-socket joint but the socket is much shallower than that in the hip joint, allowing the GH joint very little bony support. It depends upon ligaments and tendons for stability. When one or more of these is damaged, the head of the humerus may start moving too freely and slip out of the socket, resulting in shoulder instability.

Causes of Shoulder Instability

Shoulder instability can be the result of –

  • direct trauma, for example, falling onto an outstretched arm which can cause dislocation or tears in shoulder ligaments
  • congenital problems
  • repetitive strain and chronic overuse can stretch and weaken the shoulder’s ligaments and tendons, leading to instability

Pain, clicking or popping feeling, numbness during movement and tenderness are common symptoms of shoulder instability.

Treatment for Shoulder Instability

There is no common treatment for cases of shoulder instability. Treatment options would vary depending upon the severity of the underlying conditions and the intensity of pain or disability.

Conservative measures include physician-directed physical therapy and exercises, non-steroidal anti-inflammatory drugs and activity modification.

For severe cases, surgery may be required. Two types of surgery are commonly used for the treatment of shoulder instability.

  • Capsular Shift Surgery – This is an option when the joint capsule is too large. The surgeon makes a ‘tuck’ in the connective tissue which heals together, making a tighter joint capsule that holds the joint stable.
  • Bankart Repair Surgery – This is done when the joint has suffered damage to the connective tissue. The surgery repairs the ligaments that stabilize the shoulder.

Both these procedures can be done in a minimally invasive manner, causing less soft tissue trauma, less pain after surgery, and for many patients, faster recovery times.

If you or a loved one is suffering from shoulder pain, stiffness, tenderness or numbness, consult a shoulder orthopedic surgeon immediately for an accurate diagnosis and effective treatment. Any delay in treatment may worsen your condition and reduce treatment options.

Total Joint Replacement at OSPI – AZ Orthopedic Surgeons

Total Joint Arthroplasties

Joint replacement surgery, also called a total joint arthroplasty (TJA), is a common procedure used to relieve pain, improve mobility, and restore quality of life. There are many types of joint replacement procedures. Joint replacement surgery is used to replace damaged cartilage and any loss of bone structure.

The procedure is a resurfacing of the damaged joint, which relies on the ligaments and muscles for function and support. The replacement joint is called a prosthesis, which can be made of cobalt chrome, stainless steel, titanium, ceramic, or polyethylene.

Osteoarthritis and Joint Dysfunction

The most common conditions that cause joint dysfunction are osteoarthritis and rheumatoid arthritis. Many factors contribute to joint degeneration and damage, which leads to arthritis. Factors include:

  • Developmental abnormalities of the jointknee replacement
  • Heredity
  • Minor repetitive injuries
  • Abnormal cartilage metabolism
  • Severe trauma to the cartilage
  • Being overweight

Total Knee Replacement

The knee is the body’s largest joint, and it is necessary for walking, climbing stairs, and everyday activities. With age, excessive weight, and wear-and-tear from arthritis, the knee joint becomes damaged, making movement painful.

In a total knee replacement, the Gilbert orthopedic surgeon removes the degenerated cartilage surfaces at the ends of the shinbone (tibia) and thighbone (femur), and then replaces these areas with metal or plastic components. A spacer is inserted between the components so the joint will glide in a smooth fashion.

Patients who are candidates for a knee replacement are those with a knee deformity, people with chronic knee inflammation, persons who do not respond to conservative treatment, and anyone with limited movement of the knee. The Centers for Disease Control and Prevention (CDC) reports, in the U.S., more than 719,000 total knee replacements are performed each year.

Total Hip Replacement

The hip is a mobile joint, formed with a ball-and-socket. The ball and socket are both coveredcanstockphoto24680715(1) with articular cartilage, which can wear down from injury, trauma, or arthritis. This causes pain and limited mobility.

A total hip replacement involves removing the ball of the joint (femur head) and replacing it with a metal stem that attaches to the thigh bone. The damaged area of the socket is also replaced with a metal socket, and between these implants, the surgeon places a spacer that helps the joint glide easily. Candidates for a total hip replacement are patients who experience significant hip pain and stiffness, as well as people who have not responded to non-surgical methods. According to the CDC, there are more than 330,000 total hip replacements performed each year in the U.S.

Shoulder Joint Replacement

The shoulder joint consists of three bones: the humerus (upper arm bone), the clavicle (collarbone), and the scapula (shoulder blade). The shoulder is a ball-and-socket joint with cartilage on the ends of the structures to help them glide smoothly against one another. This cartilage breaks down due to arthritis and trauma, causing significant pain and loss of function. A total shoulder joint replacement involves use of prosthetic bone ends to replace the damaged areas. This surgical procedure is used for patients who do not respond to medications and those who have symptoms at rest.

Success Rates of Joint Replacement

The success rate of total joint replacement surgery is quite high. The need for repeat operation in the first ten years is less than 5%. Most replaced joints last from 10-20 years.

The Board Certified hip, knee and shoulder joint replacement surgeons at OSPI are highly skilled in the procedures. The Gilbert orthopedic surgeons offer contemporary, minimally invasive procedures that decrease postoperative pain, bleeding and speed recovery.
