This procedure involves removing the damaged joint surfaces from the ankle and then fixing the bones together. In most cases it is performed arthroscopically (i.e. keyhole techniques) and is usually carried out under general anaesthetic. Following successful ankle fusion, the ankle joint itself will not move, but there will still be plenty of foot movement through the numerous other joints in the foot, and so function remains very good.
One celebrity TV presenter with an ankle fusion is Steve Backshall, who appeared in the 2014 series of BBC’s ‘Strictly Come Dancing’. You can watch his performances on You Tube (http://www.youtube.com/watch?v=c1sWGaKTnh8) to judge for yourself the degree of function possible following ankle fusion surgery.
