If you had a pain pump for two or more days after shoulder surgery with a catheter that delivered numbing medicine directly into your surgical site, it is likely that the pain you have is related to the pain pump. Pain and loss of range of motion that develop in the weeks after the pain pump is removed can be the result of cartilage loss. This cartilage loss is called chondrolysis, and occurs because the continuous delivery of anesthetic medication directly into a joint kills cartilage cells. A simple x-ray will determine if you have suffered cartilage loss. By contacting our office, you can find out how to determine if your condition is from a defective pain pump.
