Anatomic Total Shoulder Replacement

March 9th, 2007

Anatomic Shoulder replacement (arthroplasty) has become more and more feasible since it was first introduced years ago. Traditionally, upper extremity surgeons have recommended a “Total Shoulder Replacement” when it was felt that the socket—the glenoid—was involved in the arthritic process, otherwise only the humerus was replaced for arthritis. Though glenoid-replacement components and fixation techniques have been regarded as the “weak link” in terms the most common implant-related source of complications after a total replacement, advancements have really improved outcomes following replacement of both the humerus and the glenoid. When the rotator cuff is in tact, shoulder repalcement is very successful; when the cuff is not functioning due to atrophy or an irreparable tear a Reverse shoulder implant is now the best option, in most cases.

The newest developments in the area of “glenoid resurfacing” have centered around eliminating the need for cementation—particle wear from the plastic glenoid component and the presence of cement for fixation seem not to mix well long-term in all cases. That having been said, a well executed anatomic “Total Shoulder Replacement” continues to be a superb option in patients with shoulder arthritis, particulary osteoarthritis, because it replaces like with like---the implant replaces the "anatomy" unique to you, thus the term "anatomic" replacement. . Restoration of functional range of motion and pain relief are the anticipated result (see Total shoulder arthroplasty case example). The operation requires an in patient stay for a day or two, and usually physical therapy will begin within the first week after surgery. Restoration of functional motion usually takes between 2 to 4 months.

Numerous studies have now shown that Total replacement receives higher marks than replacing just the humerus--a so called "hemiarthroplasty".

Our experience with Total Shoulders is extensive; in 2009 statistics reveal that I performed more total shoulder replacements in Rochester than any other provider, and our outcomes are superb.

So if you have shoulder pain due to arthritis, and you are looking for pain releif and better range of motion, a shoulder replacement may be a very good option for you.
