FRANKLIN, Mass., Aug. 9, 2011 /PRNewswire/ -- Arthrosurface, Inc. (www.arthrosurface.com), the developer of less-invasive joint resurfacing systems, announced that it has performed its first Total Shoulder resurfacing procedure using the new HemiCAP(GRS) glenoid system and its existing HemiCAP® shoulder. Preparation of the Arthrosurface inlay glenoid leaves the labrum intact and is implanted using an angled surgical approach instead of the more difficult and invasive straight-on technique. Adding a resurfacing glenoid to the Company's existing shoulder line provides a full portfolio from focal to total resurfacing.
"Total shoulder Resurfacing has been a goal of orthopaedics for the last twenty five years and until today, was impossible to achieve without serious compromises," said Dr. John Uribe. "When doing a traditional total shoulder replacement you remove more bone stock, the onlay glenoids have a tendency to loosen and because both implants are not anatomic you can easily overstuff the patients' shoulder joint. Using the Arthrosurface HemiCAP(GRS) inlay glenoid I can preserve bone stock and resurfacing both sides of the shoulder joint anatomically, gives me a new option, especially for younger patients."
Traditional glenoid implants require preparation of the implant site with instruments that require a straight-on surgical axis which means the humeral head has to be transected and removed to gain access to the glenoid. Taking the head off in order to facilitate the surgical exposure is the first compromise when performing a total shoulder arthroplasty. In addition, there are other weaknesses to the existing implants. Onlays sit "on" the surface instead of "in" it making them proud to the surrounding bone. This can lead to overstuffing of the joint as well as rocking of the implant as the head articulates back and forth across the implant
