But for thousands of Americans who suffer from arthritis in the shoulder, these everyday motions can be excruciating. The answer for some with chronic shoulder pain is total shoulder arthroplasty, or replacement surgery—a procedure which, according to the U.S. Agency for Healthcare Research and Quality, 53,000 Americans undergo each year. Though the surgery has been around for decades, it's recently become more accurate than ever thanks to ExactechGPS, a cutting-edge system that applies the same mapping concept to the shoulder joint that GPS uses on roads. Here, Roper St. Francis Healthcare affiliated orthopedic surgeon James Price explains how ExactechGPS (shown at right) works. Dr. James Price new horizons HC: When is total shoulder arthroplasty necessary? JP : It is most often used to eliminate the chronic, debilitating pain caused by glenohumeral arthritis, or arthritis of the shoulder. In a healthy shoulder joint, a layer of cartilage covers the humeral head and the glenoid, or the "ball and socket," allowing for smooth, pain-free movement. But when that cartilage is destroyed—be it by wear and tear over time or by trauma—the ball and socket rub bone on bone, causing extreme pain. If non-surgical treatment options have proved ineffective then total shoulder replacement surgery is an option. During this procedure, a surgeon replaces the worn humeral head and glenoid with a metal ball and plastic socket. HC: How does ExactechGPS improve the surgery? JP: During shoulder replacement surgery, visibility is very limited because the socket is tiny and you can't see behind it with the naked eye. Using ExactechGPS, a surgeon can be more accurate when placing the implant than without it. And the more accurately an implant is placed, the longer it will last. HC: How does ExactechGPS work? JP: The system lets us see inside a person's shoulder joint before and during surgery. Prior to surgery, the patient receives a CT scan. That data is uploaded to ExactechGPS, which creates a virtual shoulder model, where we are able to plan and test placement options for the prosthetic implants. Once a plan is in place, we put that data on a thumb drive and download it in the operating room. There, the system uses motion capture and infrared technology to provide the surgeon with GPS-like directions to the pre-planned placement point, recalibrating as the surgeon moves. HC: What's the recovery time like for this surgery? JP: Total shoulder arthroplasty is an outpatient procedure. Golfers are able to hit their irons again after three months and their drivers after four. Almost all patients—except those in occupations that require heavy lifting—are back to work in three months or less; people in sedentary professions may be back to work even sooner.
