Pain pumps blamed for painful chondrolysis in shoulder joints
August 21st, 2009 by Jennifer Walker-Journey
The shoulder joint has the greatest range of motion of all our joints and allows us to use our arms for various tasks, from throwing pitches to supporting our bodies. When the shoulder is injured, surgery may be required to relieve pain and restore mobility. However, some individuals have found that surgery on their shoulder has made their condition worse.
Chondrolysis is a rare condition in which the cartilage in a joint wears away causing bones to rub against bones. It was often seen in the hip where conditions such as birth defects caused the bones to rub against each other. This grinding of bones causes inflammation and pain and, eventually, destruction of the bones. It is painful and debilitating to those who suffer from this permanent condition.
In the 1990s, doctors began seeing chondrolysis in the shoulder, a place where it was rarely, if ever, seen before. As doctors began diagnosing more and more shoulder chondrolysis, also known as postarthroscopic glenohumeral chondrolysis (PAGCL), in patients who had previously had shoulder surgery, they began to make a connection between PAGCL and a new surgical use of pain pump devices used to manage pain following surgery.
That new use was to place the catheter of the pain pump directly into the shoulder joint rather than into the shoulder tissue. The constant drip of medication into the shoulder joint ate away at the cartilage in the shoulder.
It was the pain pump manufacturers who advised doctors to place the catheters directly into the joint space – a use that was not approved by the Food and Drug Administration. As a result, those manufacturers are facing hundreds of lawsuits against people who are suffering with PAGCL, a condition that is permanent and often requires shoulder replacement surgery.
