Thumb arthritis pain can be debilitating, making everyday self-care tasks intolerable. There is a surgical option when other treatments, such as injections and therapy, fail to adequately reduce pain. A carpometacarpal arthroplasty or CMC arthroplasty is a joint replacement procedure for the base of your thumb. It eliminates the grinding and pain felt from the rubbing of bone on bone after the protective cartilage has worn away, usually caused by arthritis.
Below are some commonly asked questions regarding this procedure:
Will I be in a cast?
Yes. You will likely be in a cast for 2-4 weeks. You will also use either a removable orthosis a hand therapist will custom make for you or an off-the-shelf thumb and wrist splint for a month after the cast has been removed. This will help maintain the optimum position of your thumb as you are healing and protect your new thumb joint.
What happens after my thumb has been immobilized?
Any time a joint has been immobilized, it takes time to regain your flexibility. For this surgery, the wrist and thumb are usually quite stiff. Your doctor will likely recommend you see a hand therapist to assist you with regaining the range of motion and strength safely.
