It is a surgical procedure in which all the parts or the part of the glenohumeral joint is being replaced by a prosthetic implant. This type of joint replacement surgery is conducted to relieve arthritis pain or to fix severe physical joint damage and is also an option for the treatment of severe arthritis of the shoulder joint. Generally, arthritis is a condition which affects the cartilage of the joints and as the cartilage lining wears away, there is a loss of protective lining between the bones. When this happens, generally the painful bone-on-bone arthritis develops.
Usually, severe shoulder arthritis is quite painful and can also cause restriction of motion and this may be tolerated with some medications and lifestyle adjustments, therefore, there may come a time when the surgical treatment is mandatory. A few major approaches to access the shoulder joint- first is the deltopectoral approach in which the deltoid is saved but it requires the subscapularis to be cut. The second one is the trans-deltoid approach that provides a straight on approach at the glenoid. During this approach, the deltoid is put at the risk for the potential damage.
In the traditional total shoulder arthroplasty, separation of the deltoid muscle from the pectoral muscle takes place which facilitates access to the shoulder joint through a relatively nerve free passageway. The joint is basically covered by the rotator cuff muscles and the joint capsule. A single rotator cuff muscle is identified and is cut to allow direct access to the shoulder joint. At this point, the surgeon can eradicate the arthritic portions of the joints and secure the ball and the socket prostheses within the joint.
There is an increase in the use of reverse total shoulder arthroplasty with the development of safer and more effective techniques. They are typically indicated when the rotator cuff muscles are severely damaged.
The sports injuries are those injuries which usually occurs in athletic activities or exercising. The leading cause of death mainly involves sports-related injuries, one of them which is rare a brain injury. Read more
These are generally the illnesses which affect the cervical spine and are made up of the upper first seven vertebrae that encase and shields the spinal cord. This fragment of the spinal cord begins with the region that is above the shoulder blades and ends by supporting and connecting to the skull. Read more
Generally, the knee replacement surgery is usually necessary when the knee joint is worn or is damaged to the extent where your mobility is reduced and you experience severe pain when resting. Being a major surgery, knee replacement is normally only recommended if other treatments including the physiotherapy or steroid injections have not helped in the reduction of the pain or have improved the mobility.
Symptoms of Knee Replacement
- When you feel severe pain, swelling and stiffness in your knee joint and there is a reduction of your mobility.
- When the pain in the knee is severe and it interferes with the quality of life as well as the sleep.
- When everyday tasks such as shopping or getting out of bath seem to be much more difficult or sometimes impossible.
- When you are depressed because of the pain along with the lack of mobility.
- When you are unable to work or have a normal life.
So, in this case you will also be needed to be well enough to cope up with both- a major operation and the rehabilitation afterwards. The very most common reason for the knee replacement surgery is the osteoarthritis. Some of the other conditions that can cause or are the cause of knee damage may include of:
- Rheumatoid arthritis
- Some of the disorders that cause unusual bone growth
- Knee injury
- Knee deformity along with the pain and the loss of the cartilage.
Types of Knee Replacement Surgery
Basically, there are two main kinds of surgeries which depend upon the condition of the knee that includes the Total Knee Replacement and the other one Partial Knee Replacement.
- Total Knee Replacement: In this case, both sides of the knee joint are to be replaced.
- Partial Knee Replacement: In this case, only one side of the joint is to be replaced in a smaller operation with a shorter hospital stay and the recovery period.
