Intra-articular pain pumps

Intra-articular pain pumps are medical devices that hold pain medication. The devices have a tube with a catheter attached to them and that catheter is approved by the Food and Drug Administration (FDA) to be placed in the shoulder tissue for pain relief. The catheter is sort of like a garden hose with holes in it that you place in a flowerbed. Just as water would pass through the garden hose to water plants in the bed, medication is pumped through the catheter of the pain pumps into the shoulder tissue gradually over a 48- to 73-hour period. Once the pain medication has been completely used, the patient is instructed to simply pull the catheter out of his shoulder.

Before pain pumps became available for use, patients were given medication either orally or by injection and would have to be monitored by medical staff. The use of pain pumps allowed patients to go home earlier and require less medical attention post surgery. Used properly, risks associated with pain pumps are minimal and most patients have a relatively good recovery after physical therapy. But then tragedy struck.

“With advice from manufacturers, the pain pump catheters were being placed in the joint space or intra-articular area (as opposed to the joint tissue, as was approved by the FDA) which allowed the pain medication into the joint space,” says Frank Woodson, shareholder with Beasley Allen Law Firm. As a result, “doctors began to see patients suffer severe damage to their shoulder cartilage that we’ve rarely seen before.”

The condition, called chondrolysis, is the loss of cartilage in the joint space and causes extreme pain, loss of motion and in many cases, shoulder replacement. Those who relied on their shoulder strength, found themselves suffering from career-ending injuries.

Approximately 140 lawsuits against manufacturers of pain pumps are currently filed by individuals injured by those pumps. “As patients and physicians learn more about the link between pain pumps and chrondrolysis, I think you’ll see more people come forward,” Woodson says.
