Reverse Shoulder Replacement
What Is Reverse Shoulder Replacement?
Reverse shoulder replacement is a type of shoulder joint replacement surgery used to treat severe shoulder damage, especially when the rotator cuff is no longer functioning properly.
In a normal shoulder, the “ball” (humeral head) sits on the arm bone and moves within the “socket” (glenoid). In a reverse shoulder replacement, the positions are switched: a metal ball is placed on the shoulder blade side, and a socket is placed on the upper arm bone.
This design allows other muscles, like the deltoid, to help lift the arm when the rotator cuff is damaged.
At OIBortho, our physicians evaluate and treat advanced shoulder arthritis and complex rotator cuff conditions for patients throughout Middlesex, Monmouth, and Ocean Counties.
When Is Reverse Shoulder Replacement Recommended?
This procedure is typically recommended for patients with severe shoulder damage that affects daily function and does not improve with non-surgical treatment.
It may be considered for:
- Rotator cuff tear arthropathy (arthritis with large rotator cuff tears)
- Severe shoulder arthritis with rotator cuff deficiency
- Irreparable rotator cuff tears
- Chronic shoulder pain and weakness
- Failed prior shoulder surgeries
- Complex fractures of the shoulder in select cases
Symptoms That May Lead to Surgery
Patients who may benefit from reverse shoulder replacement often experience:
- Severe shoulder pain
- Inability to lift the arm overhead
- Significant weakness in the shoulder
- Grinding or catching in the joint
- Loss of shoulder function
- Pain at rest or during sleep
- Difficulty performing daily activities (dressing, reaching, lifting)
Causes of Severe Shoulder Damage
Conditions that may lead to the need for reverse shoulder replacement include:
- Long-standing rotator cuff tears
- Advanced shoulder arthritis
- Degenerative joint disease
- Previous shoulder injuries or fractures
- Chronic instability or failed repairs
- Age-related tendon and cartilage degeneration
Over time, combined joint and tendon damage can severely limit shoulder function.
How the Procedure Works
During reverse shoulder replacement:
- Damaged parts of the shoulder joint are removed
- A metal ball is placed on the shoulder blade (glenoid side)
- A plastic socket is placed on the upper arm bone (humerus)
- The joint is repositioned to allow the deltoid muscle to lift the arm
- The implant is secured to restore stability and movement
This design helps compensate for a non-functioning rotator cuff.
Recovery and What to Expect
Recovery varies depending on health, condition severity, and rehabilitation progress.
Typical recovery may include:
- Hospital stay or short recovery period
- Sling immobilization for several weeks
- Physical therapy beginning with gentle motion
- Gradual strengthening over several months
- Return to daily activities within a few months
- Continued improvement up to a year
Most patients experience improved pain and function over time.
Risks and Considerations
As with all surgery, reverse shoulder replacement carries risks, including:
- Infection
- Dislocation of the joint
- Implant loosening or wear over time
- Nerve injury (rare)
- Stiffness or limited motion
- Persistent pain
A physician will review risks and expected outcomes before surgery.
