QUICK ANSWER: Surgical repair of your thumb is an outpatient procedure.
The ligament is anchored back to the bone using pins or sutures. Your hand / thumb is then placed into a cast or splint to protect the surgical repair.
MORE DETAIL:
Surgery is usually performed as outpatient procedure under a block anesthesia. Meaning you will be awake, but your arm is temporarily numb to the point your will feel no pain before, during and after the operation and for several hours.
Dr. Pournaras will make an incision at the base of your thumb and reattach the ligament to the bone using stitches (sutures) and small anchors. He wil also repair to the tissue around it.
Many times this surgery requires, Dr. Pournaras to repair any bone fractures with wires or screws or pin the bone back into place. He will then place your thumb in a cast or splint to protect the repairs.
After surgery, your hand and forearm will be in a cast or splint for 6 to 8 weeks.
