MEDICAL ANIMATION TRANSCRIPT: Osteoarthritis of the thumb, also known as basal joint arthritis, is a problem with the joint at the base of your thumb. Smooth cartilage covering the bones in your joint has worn away, causing pain and other symptoms. If non-surgical treatments don’t work, your healthcare provider may advice you to have a surgical procedure. One of the most common procedures for this condition is called trapeziectomy with ligament reconstruction and tendon interposition. During this procedure your surgeon will remove your arthritic trapezium bone. Next, your surgeon replace this bone with part of a nearby tendon. The tendon may be cut at one end and passed through a hole drilled in your thumb metacarpal bone. Then it will be rolled up and put into the space where the trapezium used to be. This tissue cushions your joint and keeps and keeps the remaining bones separated. To find out more about this procedure or other treatment options for osteoarthritis of the thumb, talk to your healthcare provider. more
