Shoulder Replacement Procedures

The two most common shoulder replacement procedures performed are, primary total shoulder replacement and reversed total shoulder replacement. There are different types of shoulder replacement implants available, your surgeon will evaluate you and your situation before choosing an implant that best meets your health needs.

Primary Total Shoulder: Bone Sparing Implant

For some patients a “stemless” device may be appropriate for restoring natural anatomy, function and pain reduction. A stemless device does not penetrate the shaft of the humerus (arm bone) thereby preserving precious bone stock. The humeral  joint is replaced with a bone preserving “nucleus” to which a metal humeral head is attached. The glenoid (socket) is replaced with a rounded, specialized plastic implant. See How It Works arroworange

Primary Total Shoulder: Short Stemmed Implant

With a primary total shoulder replacement, the ball (humeral head) of the shoulder joint is replaced with an implant that includes a stem with a smooth, rounded metal head. The socket (glenoid) is replaced with a smooth, rounded plastic cup that fits the head of the ball perfectly. See How It Works arroworange

Reversed Total Shoulder

With a reversed total shoulder replacement, the normal structure of the shoulder is “reversed.” The ball portion of the implant is attached to the scapula (where the socket normally is), and the artificial socket is attached to the humeral head (where the ball normally is). This allows the stronger deltoid muscles of the shoulder to take over much of the work of moving the shoulder, increasing joint stability. A reversed procedure is often indicated for patients with compromised rotator cuff function. See How It Works arroworange
