Studies link shoulder chondrolysis to pain pump devices
June 28th, 2010 by Jennifer Walker-Journey
Patients who used pain pump devices to relieve pain from shoulder surgery are at risk for permanent joint damage, according to recent studies. Pain pumps are balloon-like devices that are filled with anesthetics that deliver medication directly into the surgical space via a catheter. The medication is slowly released into the joint space for up to 72 hours following surgery and then the catheter is removed by the patient.
While this use of pain pumps was a convenient way to relieve pain from surgery, it also resulted in a surprisingly high number of cases of a painful and debilitating deterioration of cartilage in the shoulder joint known as chondrolysis, specifically Postarthroscopic Glenhumeral Chondrolysis (PAGCL). The condition is permanent and many who suffer from it require shoulder replacement surgery.
Last year, the Food and Drug Administration (FDA) issued a notice to health care professionals informing them that use of pain pump devices and anesthetics in shoulder surgery were never approved by the agency. Yet, knowing this, pain pump manufacturers still instructed surgeons to use the pumps in this manner. As a result, a surprisingly high numbers of cases of chondrolysis were reported by patients who had used the pain pumps. As many as 63 percent of patients who used shoulder pain pumps are at risk of developing chondrolysis.
Several shoulder pain pump lawsuits have been filed by people who allege that they developed chondrolysis because the manufacturers of pain pumps failed to notify the medical community about the possible harm the devices could cause. More lawsuits are expected to be filed as more victims of these devices are diagnosed.
