What is Reverse Shoulder Replacement?

May 20, 2014

Mountainstate Orthopedic Associates for shoulder replacement surgery, and we are usually asked about the reverse procedure.

The reverse shoulder replacement is a very specific replacement used for those people that have irreparable rotator cuff tears and an inability to lift their arm.  Many patients can use the other arm to lift their shoulder, but they don’t have an intact rotator cuff to help lift on the involved side.

A traditional shoulder replacement is used for osteoarthritis, which is the more common arthritis, and for rheumatoid arthritis.

Osteoarthritis is a chronic degenerative joint disease that affects mostly middle-aged and older adults.  It is characterized by the breakdown of joint cartilage.  Rheumatoid arthritis is a chronic disease that causes inflammation of the joints.

The reverse shoulder replacement differs from traditional shoulder replacement in that the two replacement parts are switched:

  1. The ball goes on the cup (glenoid) side
  2. The cup goes on the ball (humeral head) side.

This allows the arm to be raised, because it only relies on the large deltoid muscle to power it up, whereas a typical shoulder requires the rotator cuff and deltoid to work together to achieve the arm moving overhead.This replacement has become more commonplace as surgeons have become more comfortable with doing them.  Again, it is only for a small subset of patients with certain clinical findings and not something used for every shoulder arthritis patient.

A countless number of people live with shoulder pain every day.  If you are one of those people experiencing weakness or are having trouble lifting above shoulder level, you should consult one of our orthopedic surgeons.
