What will happen during thumb arthroplasty?
General or regional anesthesia will be given to keep you free from pain during the surgery. Your surgeon will make an incision on the skin over your thumb joint. He or she will remove part or all of your wrist bone. Your surgeon may also remove part of your thumb bone. He or she will reconstruct your joint using cartilage, a tendon taken from your forearm, or an artificial implant. Your surgeon will close your incision with stitches and cover it with bandages.
What are the risks of thumb arthroplasty?
You may have stiffness in your thumb after surgery. You may bleed more than expected or get an infection. If you received an implant, the implant may get loose, break, or become unstable.
