Shoulder Replacement
Shoulder Replacement
Shoulder replacement surgery, or shoulder arthroplasty, involves replacing a damaged or arthritic shoulder joint with a prosthetic implant. This procedure alleviates pain, restores mobility, and improves function for patients suffering from conditions such as rotator cuff tears, osteoarthritis, or fractures, allowing individuals to return to daily activities with enhanced shoulder performance and reduced discomfort.
Here’s how it works:
Pre-Surgery Assessment and Preparation
Before surgery, the surgeon evaluates the patient's medical history, performs physical examinations, and may order imaging tests (X-rays, MRI) to determine the extent of joint damage and decide on the appropriate type of shoulder replacement (total or partial).
Anesthesia Administration
The procedure is typically performed under general anesthesia or regional anesthesia (nerve block), ensuring the patient remains pain-free and relaxed throughout the surgery.
Removal of Damaged Joint Components
The surgeon removes the damaged portions of the shoulder joint, including the humeral head (ball) and the glenoid (socket) if necessary, to prepare for the prosthetic components.
Implantation of Prosthetic Components
A metal ball and socket, often made of cobalt-chromium or ceramic materials, are placed into the shoulder joint to replicate the natural function and movement of the original joint.
Restoration of Joint Mobility
The prosthetic components are securely fixed, either through cement or a press-fit method, and aligned to allow a full range of motion while minimizing pain.
Closing the Incision
After implant placement, the surgeon carefully closes the incision with sutures or staples, followed by bandaging to protect the site and minimize infection risk.
Post-Surgery Rehabilitation
Following surgery, physical therapy is crucial for restoring strength, improving mobility, and ensuring proper joint function. The rehabilitation process can take several months.
Common Conditions Leading to Bone Tumor Surgery :
Osteoarthritis
The most common cause, osteoarthritis results in the gradual wear and tear of cartilage in the shoulder joint, leading to pain, stiffness, and reduced range of motion.
Rheumatoid Arthritis
An autoimmune condition causing inflammation of the joint lining, leading to pain, swelling, and eventual joint damage, which may necessitate shoulder replacement.
Rotator Cuff Tear Arthropathy
Chronic rotator cuff tears, when left untreated, can lead to arthritis and significant shoulder dysfunction, ultimately requiring shoulder replacement to restore function.
Avascular Necrosis
When the blood supply to the shoulder joint is disrupted, the bone can die and collapse, leading to pain and loss of function. A shoulder replacement can be a solution to restore joint movement.
