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?

DePuy Global^® C.A.P.^® Resurfacing Humeral Head Implant

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 (humerushumerusThe bone of the arm, articulating with the scapula above and the radius and ulna below.) 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 tissuetissueA collection of similar cells and the intercellular substances surrounding them. 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 replacement surgery is the right choice. Patient‘s should consult with a physician to learn more. The performance of a joint replacement depends on age, weight, activity level and other factors. There are potential risks and recovery takes time. People with current infections or conditions limiting rehabilitationrehabilitationRestoration, following disease, illness, or injury, of the ability to function in a normal or near-normal mann... should not have this surgery. The most common adverse events after shoulder replacement are loosening, infection, and fracture of the implant or bone. The patient and surgeon must weigh the benefits of surgery against potential risks.
