Definition/Description[edit | edit source]
Ankle arthrodesis, also commonly referred to as joint fusion, is a surgical procedure which fuses the bones that form the ankle joint, essentially eliminating the joint. Ankle arthrodesis has remained the gold standard treatment for symptomatic primary, secondary and posttraumatic ankle arthritis
Indication for Procedure[edit | edit source]
Patients with longstanding symptomatic ankle arthrosis who have joints so severely damaged that usual pain management techniques fail are candidates for arthrodesis. Once conservative measures have failed, surgery should be considered. 
- Posttraumatic and primary Arthrosis
- Neuromuscular deformity
- Revision of Failed Ankle Arthrodesis
- Failed Total Ankle Replacement
- Avascular Necrosis of theTalus (requiring tibiocalcaneal arthrodesis)
- Neuroarthropathy (Charcot)
- Rheumatoid Arthritis with severe deformity
- Severe vascular deficiency
- Osteomyelitis or soft tissue infection
- Acute purulent infection
- Total avascular necrosis of the talus
- Severe peripheral arterial occlusive disease
Physical Therapy Management[edit | edit source]
As already mentioned at the indication for procedure only when conservative measures have failed, surgery should be considered. These conservative treatments include medication, bracing, orthotic management, shoe modifications, and intra-articular application of steroids..
- Immediately after the surgery, the patient will receive a wide cast covererd by a gauze dressing. Occasionally the cast needs to be decompressed, since post-operative swelling of the ankle may occure.
- Patient will be prescribed three days of bed rest.
- The initial cast is changed to a second cast at two weeks postoperative.
- After 2 months the initial cast is replaced by a weightbearing one and x-rays are taken. This implicates that weightbearing is not allowed for at least two months after operation. Only about 11 week after the operation full ankle loading is approached.
- Over a period of approximately 3 months patient will use crutches, in order to ease the ankle in its weightbearing.
- At three to four months, conversion is made to a removable walker boot and pins/screws are removed.
- It will take about four months in order to make transition to a shoe.
Based on a guideline provided by the Balance Orthopaedic Foot and Ankle Center of Long Beach, physical therapy approach after ankle arhtrodesis will emphasize maximizing residual motion, strengthening the lower extremity, and in the later phases of physical therapy, emphasis will be placed on developing maximum smoothness of walking (gait). The guideline suggest to start with isometric excercises as soon as possible, on the day of the surgery.
