This type of fracture usually occurs after a fall from a height, usually a ladder, or building. But it can also come from car crashes. It’s a very complex fracture that is complicated as usually many fractures are present and the joint cartilage falls into the bone causing the heel bone to blowout. The height of the bone shrinks, and restoring the height is crucial. Usually, another surgery is required later in life to fuse the arthritic and damaged joint.
