Reverse Shoulder Arthroplasty Performed in Pittsburgh, PA

Shoulder replacement surgery (arthroplasty) can be a good option for an adult who is middle-aged or older and has chronic shoulder pain caused by arthritis or rotator cuff disease. The goal of this procedure is to improve comfort and enhance function by resurfacing the bones that form the ball-and-socket shoulder joint (glenohumeral joint).

In general, when performing a shoulder arthroplasty, the surgeon removes the top portion of the upper arm bone (humeral head) and reshapes the shoulder socket (glenoid), then attaches prosthetic components to both bones.

What Is the Difference Between a Traditional Shoulder Arthroplasty & a Reverse Shoulder Arthroplasty?

The main difference between a traditional shoulder arthroplasty and a reverse shoulder arthroplasty is the placement of the prosthetic components. When utilizing a standard surgical technique, the surgeon attaches a metal ball to the humeral head and a plastic socket to the glenoid. To be successful, this approach requires sufficient bone stock.

Conversely, when utilizing a reverse shoulder replacement approach, the surgeon places a metal ball on the socket side of the joint, then places a plastic socket on the humeral head, where it is supported by a metal stem attached to the humerus. As such, the positions of the ball and socket are reversed, which is the opposite of the joint’s natural structure. This stabilization technique results in a semi-constrained prosthesis that stabilizes the glenohumeral center of rotation similar to a fully functional rotator cuff.

When Is Reverse Shoulder Arthroplasty Used?

Initially, reverse shoulder arthroplasty was primarily recommended for treating rotator cuff tear arthropathy, a severe and complex form of shoulder arthritis that is accompanied by a large rotator cuff tear. This condition is characterized by a loss of the cartilage that normally covers the shoulder joint surface. In addition, the tendons that normally help position and power the joint are damaged and torn.

Based on significant research breakthroughs, surgeons have recently expanded the application of reverse shoulder arthroplasty to the treatment of:

  • Massive rotator cuff tears that do not involve arthritis
  • Fractures
  • Severe bone loss
  • Rheumatoid arthritis
  • Surgical revision for failed total shoulder replacement
