Overview
Reverse shoulder replacement switches the ball-and-socket orientation to improve function when rotator cuff tendons are irreparable.

Indications
Cuff‑tear arthropathy, severe rotator cuff deficiency, or complex fractures in older adults.

Procedure overview
A ball is placed on the socket side and a cup on the arm side, allowing the deltoid to power the shoulder.

Recovery
Sling use followed by gradual rehabilitation. Functional improvements continue over months.

Risks and complications
Dislocation, infection, nerve injury, and implant loosening.

Alternatives
Non‑surgical care or tendon transfer in selected cases.
