Resurfacing Shoulder Replacement

Some of the causes for shoulder arthritis for people in their 30's to 50's include rheumatoid arthritis, post-traumatic arthritis, instability arthritis, and avascular necrosis (dead bone) due to fracture. For young, active individuals with shoulder arthritis, there are currently options to address pain and motion limitation without having to replace the entire joint. Unlike a total shoulder replacement, only the "ball" portion (humeral head) of the shoulder joint is addressed. Cartilage defects can be partially or completely "resurfaced" with a metallic cap that removes minimal bone and preserves the native anatomy for future surgery if necessary (Figure 1).

The metallic cap that is used to cover the humeral head is available with multiple sizes to best match the native anatomy of the shoulder. This procedure may be performed through a limited incision and tendon sparing approach which results in less postoperative pain and facilitates early rehabilitation (Figures 2,3, and 4).

Depending on your overall health status and severity of arthritis, this procedure can be performed on an outpatient basis. As a fellowship trained shoulder and elbow surgeon, Dr. Bohsali possesses the necessary advanced skills to perform this procedure.
