Ream and Run for Shoulder Arthritis - initial clinical results - research foundation 3

Based on the encouraging laboratory studies demonstrated in the previous posts we began offering the ream and run procedure to selected and informed patients with arthritis of the shoulder who wished to avoid the risk of glenoid component failure and the activity limitations recommended for total shoulder replacement. In this procedure, we expose the arthritic glenoid (shown below),

remove the damaged cartilage, and then ream the bone to a spherical concavity (shown below) before replacing the humeral side of the joint using the technique explained in our April 6 post.

We were truly excited to see that in many cases, after completely removing the cartilage from the surface of the glenoid, new soft tissue regenerated to cover the reamed bony surface as shown by the dark space between the metal ball and the bone of the glenoid shown on x-rays taken a year after surgery. In the x-rays shown below, this regenerative zone is marked with a red "R".
