#10 – Fibrodysplasia ossificans progressiva
That’s what a skeleton looks like when every bone has been fused together. This terrifying disease is also known as stone man syndrome; it’s one of the rarest conditions known to the medical world and there is no cure. The condition is caused by a mutation in the body’s repair mechanism that causes all damaged tissue to be replaced with a bone like substance. Any trauma to the body causes muscle, ligaments and tendons to be replaced with bone.
Surgery is the only way to remove the extra bone growth, unfortunately the trauma of surgery causes to body to increase bone production, worsening the situation. One man who suffered from this affliction donated his body to science when he died; at this point his entire body had been fused together with extra bone growth.
