It is Dr. Carrese’s opinion that “to do otherwise would be a failure of expected ethical and professional conduct, and in turn a failure of good clinical practice.”

The opinion addresses the “ethical and professional obligations of orthopedic surgeons to patients who have had arthroscopic shoulder surgery in conjunction with postoperative use of a pain pump device that infuses medication continuously via a catheter directly into the shoulder joint and who are therefore at risk for developing severe pain and disability of the shoulder joint secondary to a condition known as chondrolysis.”

Dr. Carrese is an Associate Professor of Medicine and Director, Program on Ethics in Clinical Practice, at Johns Hopkins Berman Institute of Bioethics, Johns Hopkins University.

This recommendation follows a report from the FDA distributed today to health care professionals following a review of 35 reports of chondrolysis (necrosis and destruction of cartilage) in patients given “continuous intra-articular infusions of local anesthetics with elastomeric infusion devices to control post-surgical pain.” According to the study, 97 percent of the reported cases of chondrolysis followed shoulder surgeries.

The FDA report says early adverse affects following pain pump use after surgery included joint pain, stiffness, and loss of motion, occurring as soon as two months after surgery. In half the reported cases, the FDA report notes, patients required additional surgery, including arthroscopy or arthroplasty (joint replacement).

A number of lawsuits have been filed on behalf of patients suffering from chondrolysis as a result of pain pumps being inserted directly into the cartilage rather than into the muscle tissue following surgery. The FDA only approved pain pump use as inserted in the muscle tissue, but the lawsuits allege pain pump manufacturers marketed the devices to physicians with instructions to insert the catheter into the joint for faster and more efficient pain relief.

However, studies show that introducing the anesthetic medications directly into the joint in this manner destroys the cartilege and results in chondrolysis.

One of the complainants, Glen Gore, says a Stryker pain pump was implanted in his shoulder after repair surgery in December 2002. After using the pain pump, he was had lost almost all of the cartilage in his shoulder joint, is unable to raise his arm above shoulder level, and now needs replacement surgery.

Gore is among hundreds of patients who are suing the manufacturer of the pain pumps used in shoulder surgery after the pain pumps caused serious and likely permanent injury to their shoulders. The problem dates back to the early 2000s, when pain pump manufacturers began instructing doctors to place the catheter of the pain pump directly into the shoulder joint. The Food and Drug Administration (FDA) had previously approved its use with the catheter placed in the shoulder tissue but had rejected the manufacturers’ request to have the alternative catheter placement approved, citing the need for studies to ensure the safety.

Placed in the shoulder joint, the catheter dripped medicine that began eating away at the cartilage. Doctors soon began to make the connection between the pain pumps and a condition known as chondrolysis, or specifically Postarthroscopic Glenohumeral Chondrolysis. As a result, pain pump manufacturers like Stryker are facing numerous lawsuits from individuals who have been irreversibly harmed by their product.

Postoperative pain pumps are a pain-management system designed to deliver medication directly to the surgical wound or in close proximity to the nerves associated with the surgical area. A recent study published by The American Journal of Sports Medicine identified the post-operative pain pumps as the likely cause of articular chondrolysis, a progressive degeneration of the cartilage. Chondrolysis of the shoulder results in the narrowing of the joint space, which can cause pain and loss of motion. Chondrolysis is a chronic condition that often requires surgery.

As of July 2008, Health Canada had received eight reports of articular chondrolysis one month to one year following shoulder surgery. In all cases, the chondrolysis was thought to have been related to pain pumps. All patients listed in the incidence reports received bupivacaine, a local anesthetic, with epinephrine, a hormone and neurotransmitter.

Instructions for use on the label of the postoperative pain pumps discourages continuous intra-articular infusion of anesthetics, particularly when epinephrine is used.

In its announcement, Canada Health also urged health care professionals to report any adverse incidents following the use of pain pumps or other medical devices to the Health Products and Food Branch Inspectorate through the Inspectorate Hotline at 800-267-9675.
