Could an ankle fracture be practically painless?

It can. Sometimes the fracture is of one bone only or may be small enough that patients will present with complaints of long term pain they thought was a an ankle sprain.
There should be pain. Fractures are broken bones, and there will be pain when a bone breaks. Different people have differing perceptions of pain, so it's possible for somebody with a very high pain tolerance to say his ankle fracture was "practically" painless.
Yes. Some people have a minor ankle fracture. Others have a high tolerance to pain. Others have neuropathy and cannot feel pain normally. But, most people will have pain when they have an ankle fracture.

What are the signs of ankle fracture?

Pain, bruising. There usually is an injury associated with this condition which will have signs of bruising, swelling, and pain. If the fracture is real bad, one can see an obvious alignment deformity of the affected limb. One may even have blisters associated with the rapid swelling that occurs.
Fracture. Pain, swelling, loss of motion or stiffness of the joint, deformity, difficulty bearing weight. This can be difficult to differentiate from a severe sprain or contusion without an xray.

What are the tests for ankle fracture?

X-ray. Most commonly done is an x-ray, 3 views of the ankle. This should show any fractures through the bones including the surface (cortex) of the bone. Sometimes an MRI is needed when you have a bone bruise or internal fracture of a bone not involving the surface. In this scenario, a regular x-ray may look normal but an MRI will show a bright white spot at the fracture on a stir image.
Exam and x rays. Ankle fracture are associated, with pain, tenderness, swelling and deformity around the ankle, radiographs are used to diagnose ankle fracture.
Xrays. The most telling way is to obtain ankle x-rays to visualize the fracture or lack thereof. Sometimes, if there remains suspicion in the presence of 'negative' films or if a stress fracture is suspected, specialized exams may be ordered to see if a fracture exists.

What sort of problem is an ankle fracture?

Bone injury. If the multiple bones in the ankle break, they will bleed at the fracture site. This blood will clot and form the matrix ie the building forms upon which the new bone cells will eventually form from new bone forming cells that develop. In order to prevent the bone edges from moving around, that would cause much more pain and delayed or even non healing, casting or screwing bone is needed.
Varies by severity. Some ankle fractures are stable and can be treated in a boot or brace (usually when just the fibula bone is broken and the ligaments are minimally injured). Unstable fractures (both bones broken, or one bone with severe ligament injury) will require surgery for best outcomes.

How is an ankle fracture typically treated?

It depends. Some ankle fractures can be treated with braces and early weight bearing, while some require extensive surgery, and long periods of not putting weight on it. X-ray is extremely important in diagnosing and directing treatment of ankle fractures.
Depends on Severity. Ankle fractures can be simple avulsion fracture where a ligament pulls on an attachment to bone and cracks it. These can be treated with cast immobilization if they are not displaced. Usually displaced fractures need to be fixed due to soft tissue which may fall into the separation and keep a fracture from healing. Most ankle fractures are from twists and may need surgery if displaced or short.
Depends. It depends on what kind of fracture it is. It could be treated conservatively in a cam boot or a cast. It may need surgery to secure the bones together so they heal properly.

How is an ankle fracture typically diagnosed?

X-rays. It is best determined if there are any fractures on radiographic examination.
Go to a podiatrist. A podiatrist can take x-rays if indicated and treat you with a variety of modalities based on the findings of the history of the injury and physical exam. Sometimes there can be damage to areas away from the ankle that a podiatrist will know to look.
