Mr Barry Francis “the Foot Surgeon” picked this up while on the train reading the Daily Mail last week. One of the less common problems that can occur with the foot is a small extra bone at the back of the ankle. Often people go through life happily with this but if it becomes amaged then it can cause pain and a change in function. The bean-shaped bone is called an os trigonum. In the Daily Mail last Tuesday a keyhole surgery approach is described in removing this bone.
Problems with it often follow a small accident, such as a wrench of the ankle or sprain, and the patient will often experience a clicking sensation in the ankle with pain. The ankle itself might feel unstable. Proper diagnosis is important and this often requires a CT and/or MRI scan. The procedure can be carried out under minimal incision or perhaps more often through open incision from the side of the ankle.
Until the next time Barry.
