Shoulder Resurfacing
What is Shoulder Resurfacing?
 

Shoulder resurfacing is a more conservative alternative to traditional shoulder replacement surgery. Resurfacing allows patients to retain more of their natural bone, replacing only the diseased surface of the joint instead of the entire joint. Shoulder Resurfacing is potentially less traumatic, less invasive, and preserves more bone. This gradual approach to surgery means a patient may still be able to have a total shoulder replacement later if necessary. In a recent study of shoulder resurfacing, most patients reported being very satisfied with the results, and 85% were able to return to sports activities at their desired levels.1 In a study of hundreds of patients who had shoulder surgery, more than 95% reported having less pain afterwards.2

Who is a candidate for shoulder resurfacing?
 

If you are suffering from rheumatoid arthritis or osteoarthritis of the shoulder, you may be a candidate for joint resurfacing using the Global C.A.P. implant.  Resurfacing is intended to repair arthritic damage and humeral head fractures, but not rotator cuff tears. The implant is not intended to be used in patients with local infections or poor bone quality. Resurfacing can be used in younger patients with mild to moderate arthritis that is confined to the humeral head.

What is replaced with the Global C.A.P. product?
 

As the name Global C.A.P. suggests, only the ball surface of the shoulder is replaced, providing a cap over the ball of the shoulder joint. The surface is smoothed and capped leaving the majority of the arm bone (humerus) intact.

Why choose DePuy Global C.A.P. resurfacing?
 

The DePuy Global C.A.P. design focuses on sparing as much healthy bone and soft tissue as possible. The cap covers the moving part of the upper arm bone and is held in place by a press-fit stem. This means the implant will be put in place without bone cement. Instead, tissue will naturally grow onto the implant’s rough porous underside, securing the implant. The DePuy Global C.A.P. allows for a minimally invasive approach, which may reduce pain and provide a quicker recovery.

Note

Only an orthopaedic surgeon trained in shoulder replacement can provide advice about whether shoulder resurfacing surgery is right for you. See your physician to learn more. As with any surgery, there are potential risks and recovery takes time. The performance of a joint replacement depends on age, weight, activity level, preoperative condition and other factors. The most common adverse events after joint replacement are loosening, infection, and fracture of the prostheses or bones. You and your surgeon must weigh the risks of surgery against its possible benefits.

Adverse Events

The following are the most frequent adverse events after shoulder arthroplasty: change in position of the component, loosening of components, dislocation, infection, hematoma, pneumonia, and cardiovascular disorders.
