Reverse vs. Anatomic Shoulder Replacement

An anatomic replacement follows the shoulder's natural ball-and-socket arrangement and depends on a functioning rotator cuff. A reverse replacement switches the ball and socket positions and relies more on the deltoid muscle to lift the arm. Neither design is the right choice for everyone.

Rotator cuff function, arthritis, bone shape and loss, fractures, and previous surgery can influence the choice. Reverse replacement may be considered when the rotator cuff cannot support an anatomic replacement or in other complex situations. Imaging and examination are needed to apply these considerations to your shoulder.

Ask why the recommended design fits your findings, what alternatives remain, and which personal goals are realistic. Discuss risks such as infection, instability, nerve injury, implant problems, and the possibility of further surgery. Expected benefits and risks depend on your health and the condition of the shoulder.

Recovery involves protecting the shoulder and gradually rebuilding function. Ask for an individual plan for sling use, therapy, help at home, driving, work, and lifting. Do not treat another person's recovery schedule as your own instructions.
