Arthrodesis of Foot and Ankle—Open Surgery
Pronounced: AR-throw-DEE-sis of foot and an-kuhl
Arthrodesis fuses the two bones that form a joint. There is no longer movement in the joint after the procedure. One or more related joints may be done at the same time.
Reasons for Procedure
Ankle and foot arthrodesis is done to relieve disabling ankle or foot pain, or deformity caused by poorly healed fractures, arthritis, infections, or developmental defects.
The procedure results in pain relief in most patients. Some may be able to wear ordinary shoes while others may benefit from specially fitted footwear.
Complications are rare, but no procedure is completely free of risk. If you are planning to have an arthrodesis, your doctor will review a list of possible complications, which may include:

What to Expect
Prior to Procedure
Several nonsurgical treatments will be tried to correct the problem before choosing surgery. These may include medicines, injections, special shoes, or types of physical therapy. You will have a thorough evaluation to determine your overall health and any risk factors.
Talk to your doctor about your medicines. You may be asked to stop taking some medicines up to one week before the procedure, like:

Description of the Procedure
The doctor will make a long incision to view the joint. The joint will be secured. There are many ways to secure the two bones together so that they no longer move in relation to one another. Long screws, screws and steel plates, long steel rods, and bone grafts have all been used.
You will have a tight bandage strapped around your thigh to shut off circulation during surgery. This will not harm your leg.
Immediately After Procedure
Your lower leg will be in a rigid cast and be elevated after surgery. You will be offered pain medicine.
How Long Will It Take?
About 2-3 hours
How Much Will It Hurt?
There will be no pain during the procedure. Afterwards, there will be some discomfort. Talk to your doctor about medicine to help manage discomfort.
Average Hospital Stay
You may be able to go home in 2-4 days if you do not have any complications.
It will take up to four months to heal and solidly fuse the joint(s). During that time, you will be in a cast. After the procedure, be sure to follow your doctor's instructions. Ask your doctor about when it is safe to shower, bathe, or soak in water.
