The shoulder -joint is one of the biggest joint in the upper body.
It is a complex Ball-and-Socket type of joint, that is responsible for the majority of the
movements at the arm.
Basically, a shoulder joint anatomically is formed by the longest bone in the arm, that is the humerus and the Glenoid Cavity that is the part of the Scapular bone. The amalgamation of these bones forms the Shoulder Joint.
It is common for the joints, that are responsible for a larger number of movements, to get easily worn out with age, and can easily succumb to many injuries as well.
Just like the Knee Arthroplasty, the shoulder-joint can also undergo an Arthroplasty. The
the procedure can be different depending on the type of pathology or trauma.
Mainly 3 types of procedures are performed: –
• Shoulder Hemiarthroplasty
• Total shoulder arthroplasty
• Reverse total shoulder arthroplasty
Commonly shoulder Hemiarthroplasty is performed.
Basically, in this procedure instead of complete replacement of both the glenoid and the
humerus, only the humerus is replaced by a prosthesis and glenoid is kept intact.
It’s a very common procedure and routinely done.
Basic indications for Shoulder Hemiarthroplasty is very bad proximal humerus fracture which cannot be fixed with plate and screw. In such fractures, the glenoid will be normal and hence left alone without replacing.
Total shoulder replacement – The surgery can be done for Chronic Joint disease with advanced pathology or in severe osteoarthritis of the shoulder joint, where no other option remains.
Reverse shoulder replacement – This is a very good procedure done in patients who have torn rotator cuff with arthritis of shoulder joint.
Why is it called reverse? What that means?
In normal total shoulder replacement, the humerus head is replaced with the ball and glenoid is replaced with the socket. But in reverse, this combination is reversed. Reverse shoulder the replacement has shown very good results in the patient having a tear in the surrounding muscle ( Rotator Cuff) with arthritis.
The main aim of the surgery is to provide pain relief, improve all complex motions like
Overhead movements and better strength to endure daily activities etc.
The risk factors are minimal, and the prognosis of the treatment has been good enough as per data, post-op complications are minimal.
Post-op the patient recovers quickly and soon enough with extra efforts of physical rehabilitation and care.
