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.

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.

Shoulder replacements are generally applied in the following cases:

1. 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.

2. 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.

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.
