What are Shoulder Replacements?
Shoulder replacements are surgical procedures aimed at relieving pain and improving mobility in cases of shoulder joint arthritis and other issues. The shoulder joint is the most mobile joint in the body, playing a critical role in arm and hand movements. The primary goal of shoulder replacement surgery is to eliminate pain and restore joint function, thereby enhancing the patient's quality of life.
How Are Shoulder Replacements Performed?
Shoulder replacement surgery is typically performed under general anesthesia. The surgeon accesses the shoulder joint, removing damaged bone and cartilage surfaces. Then, appropriately sized metal and plastic implants are placed on the joint surfaces, helping restore normal joint functions. The rehabilitation process begins post-surgery, with physical therapy and exercises to enhance shoulder mobility.
In Which Cases Are Shoulder Replacements Applied?
Shoulder replacements are generally applied in the following cases:
-
Shoulder Joint Arthritis: Arthritis in the shoulder joint can occur due to various reasons, including idiopathic arthritis (unknown cause), post-traumatic arthritis (following an injury), rheumatoid arthritis, rotator cuff tear arthropathy, and unreduced old shoulder dislocations.
-
Shoulder Fractures: Partial shoulder replacements (hemiarthroplasty) can be performed for 3-4 part fractures of the shoulder head, where prosthetics are used to reshape joint surfaces and restore normal function.
Considerations for Shoulder Replacements
The success of shoulder replacement surgery depends not only on the quality of the surgical procedure but also on postoperative care and rehabilitation. While the risk of infection is minimal, attention should be paid to preventing postoperative infections. The rehabilitation process is crucial for regaining full shoulder joint function.
Anatomic vs. Reverse Shoulder Arthroplasty in Istanbul
Shoulder replacement surgery at İSOM Orthopedic Clinic encompasses both anatomic total shoulder arthroplasty and reverse shoulder arthroplasty (RSA). Anatomic arthroplasty replicates normal ball-and-socket anatomy in patients suffering from glenohumeral osteoarthritis with an intact rotator cuff mechanism.
In contrast, reverse shoulder arthroplasty is indicated for patients with rotator cuff tear arthropathy, complex proximal humeral fractures, or failed previous reconstructions. By transposing the center of rotation and utilizing a semi-constrained glenosphere, RSA empowers the deltoid muscle to lift the arm overhead without relying on a compromised rotator cuff.
- Anatomic Arthroplasty: Preserves natural joint kinematics, requiring a competent subscapularis and supraspinatus for optimal stability.
- Reverse Arthroplasty: Restores functional active forward elevation and abduction even in the presence of severe tendon retraction.
- 3D Pre-Operative Glenoid Templating: Ensures ideal central screw purchase and retroversion correction in deformed glenoid anatomy.
- Low-Friction Articulations: Combines highly polished cobalt-chrome humeral heads with compression-molded ultra-high-molecular-weight polyethylene.
Shoulder Rehabilitation and Functional Recovery Protocol
Post-operative rehabilitation is pivotal to maximizing active forward elevation, external rotation, and internal rotation. At İSOM, rehabilitation begins immediately with pendulum exercises, scapular stabilization, and passive forward flexion under the guidance of specialized upper-extremity physiotherapists.
Active-assisted range of motion commences at week 4, transitioning to isometric and progressive resistive strengthening of the periscapular and deltoid musculature by week 8.
