A Mid Foot Fusion, or arthrodesis, is a procedure where one or more of the metatarsal cuneiform joints or intercuneiform joints are fused. This is a surgical technique used to treat some types of midfoot arthritis. Surgery to make two or more different bones grow together is called Arthrodesis, or Fusion. It is sometimes performed on patients who have previously had a fracture or dislocation, and experience chronic pain. Some patients with rheumatoid arthritis or osteoarthritis will benefit from this surgery.
This surgery can be done as an outpatient. You will need a General anesthetic or Spinal anesthetic.
During the surgery, one or more parallel 3 inch long incisions are made on the top of the midfoot. The bone ends are prepared by removing any remaining cartilage. They are held together with one or more screws.
A Bone Graft is occasionally used to fill any gaps and improve the chances of a solid fusion. This is routinely taken from the iliac crest, above the hip, on the same side as the foot. If it’s anticipated that a bone graft will be needed, your doctor will likely ask that you spend one night in the hospital after the surgery.
