But beginning in the 1990s, orthopedic surgeons began seeing more and more patients who were complaining of limited range of mobility, pain and stiffness in their shoulder. Tests showed the cartilage was beginning to or had completely worn away causing bone to rub against bone, also known as chondrolysis. Doctors were baffled.

What they soon discovered is that all the patients who were developing or had developed chondrolysis had had shoulder surgery during which a pain pump was used to deliver anesthetics for 48 to 72 hours following surgery. The pain pumps were a new offering for surgeons who previously prescribed IV or oral painkillers to patients to help deaden the pain of shoulder surgery.

Pain pumps are balloon-like devices filled with anesthetic that rests outside the body. The anesthetic is administered directly into the joint space through a catheter, which is removed after the medication has been used. Pain pump manufacturers were quick to promote this new use of pain pumps to doctors in the 1990s even though the use was never approved by the Food and Drug Administration (FDA).

What doctors didn’t realize at the time is that the pain pumps, which dripped medicine directly into the joint space, were causing the cartilage in the shoulder to wear away. Doctors soon made the connection between pain pumps and shoulder chondrolysis. Last year, after studies on shoulder chondrolysis had been published in several medical journals, the FDA issued a warning to doctors informing them that pain pumps should not be used during shoulder surgery and that this use has never been approved by the agency.

The labrum is a cartilage found in the shoulder’s ball-and-socket joint where the arm meets the body. It serves to deepen the socket so that the ball stays in place and helps stabilize the arm. When the labrum is torn due to injury, the ball may slide part or all of the way out of the socket. Symptoms of a labral tear depend on where the tear is located, and may include an aching sensation in the shoulder joint, catching of the shoulder when moved, and pain during physical activity.

Treatment for a torn labrum depends on the type of tear. They often do not require surgery; however, patients with persistent symptoms that do not respond to other therapies may need surgery. Recovery from surgery usually depends on where the tear occurred and how severe the tear was. Typically, it takes four to six weeks for the labrum to re-attach itself to the rim of the bone and another four to six weeks to strengthen and fully heal.

A majority of patients regain full functioning of their shoulder after labrum repair, but that was not always the case. Just a few years ago orthopedic surgeons began seeing more and more patients suffering from a painful and debilitating condition known as chondrolysis in patients who had had shoulder surgery. The condition was traced back to pain pumps used to deliver medication to the shoulder joint for up to 72 hours after surgery.

An investigation found that pain pump manufacturers were advising doctors to insert the pump catheters directly into the shoulder joint rather than the tissue, as was approved by the Food and Drug Administration (FDA). As a result, more than 140 lawsuits have been filed in state and federal court against manufacturers of pain pump devices.

The On-Q PainBuster pain pump offers an alternative to traditional intravenous and oral painkillers, which can leave patients feeling groggy. The pain pump uses a small balloon that holds a local anesthetic that is fed through a thin antimicrobial catheter that is inserted into the surgical site. The device injects the pain relief medication directly to the surgical site on a continuous basis for up to 72 hours following surgery. Following surgery, the patient goes home with the implanted device and after two or three days, the patient gently pushes out the catheter and discards the device.

Doctors who have used the pain pumps for hysterectomies and C-sections say the device helps women get up and about faster than using more traditional pain meds.

The I-Flow On Q PainBuster pain pumps have been a popular choice for orthopedic surgeons performing knee and shoulder surgeries. The pain pumps are designed and intended to be used with anesthetics that are administered continuously over time.

However, in shoulder surgeries in particular, the medication delivered directly to the surgery site has caused serious and permanent damage to the cartilage of the shoulder joint. This narrowing of the joint space is known as chondrolysis, a condition in which the complete or nearly complete loss of cartilage in the shoulder joint. Chondrolysis is an irreversible disabling and extremely painful condition.

A recent study published by The American Journal of Sports Medicine identified these intra-articular pain pumps as the likely cause of chondrolysis in shoulders.

There do not appear to be any reported problems with pain pump use following C-sections and hysterectomies at this time.
