During the examination, an X-ray machine sends a beam of radiation through the foot, and an image is recorded on special X-ray film or a computer. This image shows the soft tissues and bones of the foot, which include the tarsal bones (ankle bones), metatarsal bones (front end of foot), and phalanges (toes). The X-ray image is black and white.
How much do foot and ankle X rays cost?
How much does ankle surgery cost? Without any health insurance, diagnosing your ankle and creating a treatment plan can cost about $500 to $1,200 for just the doctor’s visit and ankle x-rays. The costs will come down to your geographical location, the severity of your injury, your insurance company, the doctor you use and the type of treatment required.
What will they do at a foot x-ray?
A foot X-ray can detect infection, cysts, or tumors in the leg . A foot X-ray can detect broken bones, assist a physician in setting the broken bone, and can monitor the treatment process to determine whether the bone is properly aligned and the break is healing properly.
Do I need an X-ray on my ankle?
Rule number two states if the bony projection on the inner half of your ankle, the medial malleolus, hurts to touch then it's time to get an x-ray. The next rule is pain over the bone located at the inner part of the arch of the foot known as the navicular bone.
Do I need a Xray after an ankle sprain?
Ankle sprains are one of the most common injuries in athletes. Most times, ankle sprains do not require an x-ray or surgery. However, sometimes an ankle sprain can be accompanied by a fracture in the foot or ankle which could require a different treatment protocol from a sprain. Types of Fractures
What is a complete foot X-ray?
In a foot X-ray, an X-ray machine sends a beam of radiation through the foot, and an image is recorded on special X-ray film or a computer. This image shows the soft tissues and bones of the foot, which include the tarsal bones (back end of the foot), metatarsal bones (front end of foot), and phalanges (toes).
What is the X-ray of ankle called?
An ankle x-ray, also known as ankle series or ankle radiograph, is a set of two x-rays of the ankle joint. It is performed to look for evidence of injury (or pathology) affecting the ankle, often after trauma.
What does an ankle X-ray Show?
An ankle X-ray can help doctors find the cause of pain, tenderness, and swelling, or deformity of the ankle joint. It can show broken bones or a dislocated joint. After a broken bone has been set, an X-ray can show if the bones are aligned and if they have healed properly.

Do sprains show up on xrays?
While a sprain will not show on an x-ray, the imaging can help rule out a broken ankle or foot bone. Persistent swelling: If you have swelling that doesn't go down after several days, an x-ray can reveal if there is something else going on, such as a bone fracture or fluid around a joint.
When should I get my ankle checked?
Have severe pain or swelling. Have an open wound or severe deformity. Have signs of infection, such as redness, warmth and tenderness in the affected area or a fever greater than 100 F (37.8 C) Cannot put weight on your foot.
Can you walk with a torn ligament in the ankle?
Can You Walk with a Torn Ligament in Your Ankle? Yes, you can usually walk with a torn ligament thanks to the other ligaments and supporting structures, but you may feel a lot of pain and a sensation of weakness and instability as you walk.
Can you walk on ankle fracture?
Most people with a fractured ankle can't put weight on it. A fractured ankle or significant sprain causes immediate swelling and the ankle cannot be moved. The key difference is that sprains tend to heal in a week or two and the pain diminishes. A fracture will hurt until it is treated.
What happens if you leave a sprained ankle untreated?
If an ankle sprain is left untreated, it may lead to a chronically unstable ankle joint and, from there, to degenerative and arthritic changes in the ankle, as well as chronic tendon inflammation. It may also feel as if the ankle is constantly trying to give out, which can, from there, cause a re-injury of the ankle.
Why do we need x-rays?
An x-ray is useful in determining whether there is a bony injury like a fracture or broken bone. Some simple rules (Ottawa ankle rule) can be helpful in deciding if you need to get x-rays.
What to do if your ankle is giving away?
If the above rules do not apply to you but you are still having significant pain, swelling, weakness, or a sensation that the ankle or foot is giving away, physical therapy may be for you. A physical therapist can perform a thorough physical evaluation and in most cases determine the most appropriate course to manage your symptoms ...
What to expect during a foot xray?
What to Expect During Your Foot X-Ray Procedure. Before the x-rays are taken you will be asked to take off your shoes and socks and roll up the legs of your pants. You will need to remove any jewelry or metal objects you may be wearing—for example, an ankle bracelet or toe ring.
Why do you need an x-ray for foot pain?
Even if none of those conditions are suspected, x-rays are often useful for diagnosing mysterious aches and pains. If you are experiencing foot pain and do not know the cause, x-rays may help you and your doctor to arrive at the answer.
Why is osteoporosis visible on x-rays?
Osteoporosis, a condition in which the bones become weak and brittle, is detectable on an x-ray image because the radiation passes more easily through the places where bone density has been lost, and these areas show up on the image as darker spots.
How long after a cast is off can you take x-rays?
If you have a broken or fractured bone in your foot or ankle and need to wear a cast for a few weeks, x-rays will also be taken after the cast comes off in order to make sure that the bone has healed correctly and is properly aligned.
What to do if you have a broken foot?
If you’ve injured your foot and your doctor suspects that a bone may be broken or fractured, he or she may want to take x-rays. In addition to determining whether bones have been broken or fractured, X-ray images can also be used to detect arthritis, osteoporosis, dislocations, or tumors.
What color are bones in a photo?
In the photographic image that is produced, the soft tissues appear a very dark gray, but the bones appear white, as does anything else that is dense enough to block most of the radiation passing through your body.
What material blocks x-rays?
The x-ray radiation passes easily through the soft tissues in your body, but denser material such as bone—or a metal foreign object— blocks it, just as your body blocks sunlight to cast a shadow on the ground in front of you.
Why do you need an ankle xray?
Simply put, there are 5 reasons to get an ankle x-ray. 1. You can’t walk on the ankle. 2. You have tenderness at the outside ankle bone (fibula). 3. You have tenderness at the inside ankle bone (tibia). 4. You have tenderness at the outside of the foot (at the “styloid”).
What side of the ankle do you press on?
If you press on the left tibia, you would be pressing on the right side of your left ankle. If you have pain or tenderness when you “palpate” or push on either the fibula or tibia (as illustrated in the pictures), you definitely should have x-rays of the ankle to make sure it isn’t broken.
What is the fibula?
The fibula is the hard knot of bone you feel as the ankle bone on the outside of your ankle. For example, if you sprain your left ankle and press on the left fibula, you would be pressing on the left side of your left ankle. If you press on the left tibia, you would be pressing on the right side of your left ankle.
Where is the bump on the foot after a sprain?
To decide whether or not we should take xrays of the foot after you sprain your ankle, we (as foot doctors) would also “palpate” (poke around) on the navicular bone and the bump on the end of of the fifth metatarsal called the “styloid process.”
Is it better to rest or ice your ankle?
Ankle sprains are the most common of all musculoskeletal sports injuries. But not all injured ankles are treated the same. Mild ankle sprains get better with rest, ice, compression and elevation. Severe ankle sprains need t be protected and immobilized as well. But fractures (broken ankle bones) need strict immobilization or surgery.
Who can treat ankle sprains?
This includes, ER doctors, orthopedic surgeons and podiatrists.
Can you get an x-ray if your ankle is broken?
Many people think that the amount of ankle swelling, ankle pain, or bruising of the ankle can be used as a guide to whether or not the foot is broken and needs an x-ray. But this is false! Fractures and severe ankle sprains look very similar. They all have pain, bruising and swelling.
What is the purpose of a radiograph of the foot and ankle?
Radiographs of the weight-bearing foot and ankle can demonstrate the foot and ankle in a more functional situation and may provide insight into the relationship among the soft tissues, bones, and the joints under physiologic loads. Some important points of consideration are as follows:
How many types of radiographs are there?
In total, there are four types of radiographs. These are listed in Box 2.1.
What is stress radiography?
Stress radiography is used for the diagnosis and evaluation of trauma as well as disorders of ankle and midfoot. ♦ In painful conditions, stress radiography can be done after injecting local anesthetic in the area of pain.
What is the plane of imaging in the ankle?
Image orientation ( Box 16-1 ): Planes of imaging in the ankle are standard and identical to elsewhere in the body. The foot is more complicated. For purposes of this chapter, we consider the images that run parallel with the long axis of the foot and appear similar to an anteroposterior foot radiograph as either long-axis axial or long-axis coronal images. Images obtained perpendicular to the long axis of the foot so that the metatarsals are seen as five circles of bone cut transversely are referred to as short-axis axials . Sagittal images are self-explanatory and standard.
How to do ankle MRI?
Coils and patient position: Ideally, imaging of the ankle and foot should be done with the foot at right angles to the lower leg with the patient in a supine position. This positioning may require a support on the sole of the foot to maintain the alignment (special surface coils are now being made to accomplish this). A standard extremity coil generally is employed for the foot and ankle (the same one used for knee MRI), and such a precise position for the foot is not always possible to obtain or maintain. More importantly, the patient should be immobilized with padding and made comfortable to prevent movement that would degrade the images, and the radiologist should know the anatomy well enough so that it is easily interpretable, regardless of slight variations in the angle of the foot with the ankle. How to angle MR images properly with the anatomic planes of the foot and ankle to obtain images that are reproducible and most easily understood is shown in the protocols of how to image the foot and ankle. The lower extremity externally rotates when a patient is in a relaxed supine position, and the planes of imaging must be oriented to the anatomy of the foot, rather than to the magnet. True sagittal images of the foot and ankle are mandatory to show the Achilles tendon accurately. If a slice cuts through the tendon obliquely, it gives the false impression of abnormal thickening of the tendon. Imaging the forefoot or toes often is done with the patient prone to allow the toes to be in a neutral position, more easily immobilized, and better centered in the coil. Some centers routinely image the foot and ankle in the prone position to decrease the magic angle effect. Only the extremity with a suspected abnormality is imaged; the opposite normal side is never done simultaneously for comparison because it is unnecessary, and decreases the detail and resolution of the images owing to the larger field of view required. We try to employ a small field of view to increase resolution, so we divide the foot and ankle into one or the other and never scan both simultaneously. An ankle MRI does not include the toes and a forefoot examination does not include the ankle.
What are the four tendons that are anterior to the ankle?
16-1 ). From medial to lateral these are the anterior tibial, extensor hallucis longus, extensor digitorum longus, and peroneus tertius tendons. These tendons dorsiflex the ankle and foot. These tendons seldom are affected with pathology compared with the flexor tendons, so little attention is paid to these structures.
What tendon is on the medial side of the ankle?
The posterior tibial tendon is the most common abnormal tendon on the medial side of the ankle. This tendon provides a significant amount of support to the arch of the foot, and tears of the tendon can cause loss of the longitudinal arch, resulting in a flatfoot deformity. Middle-aged or older women and rheumatoid arthritis patients often have this abnormality.
Which tendon divides to send insertions to the plantar aspects of the distal phalanges of?
The flexor digitorum longus tendon is rarely involved with abnormalities. It passes just lateral to the posterior tibial tendon and divides to send insertions to the plantar aspects of the distal phalanges of the second through fifth toes.
Where are the tendons located in the foot?
The peroneus brevis and longus tendons are located on the posterolateral aspect of the ankle and serve as the major everters of the foot (see Fig. 16-1 ). These tendons pass posterior and inferior to the lateral malleolus, which they use as a pulley. The tendons share a common tendon sheath proximally, but have separate sheaths distally. The brevis usually is located anterior to the longus (although the brevis sometimes may lie medial to the longus) and runs in a shallow retromalleolar groove on the back of the lateral malleolus ( Fig. 16-16 ). The peroneal tendons are held in place relative to the lateral malleolus by the superior peroneal retinaculum. The tendons often are separated by the small peroneal tubercle on the lateral aspect of the calcaneus, with the brevis passing anterior to the tubercle (see Fig. 16-16 ), or both tendons may pass anterior to the peroneal tubercle. The brevis eventually attaches to the base of the fifth metatarsal. The longus has a broad-based insertion on the plantar surface of the base of the first metatarsal and medial cuneiform, after traversing the plantar aspect of the foot.
What are the abnormalities of the foot and ankle?
Tendon abnormalities affecting the foot and, particularly, the ankle are common because of the many tendons that are present and their close relationship to adjacent osseous structures that may cause irritation, and the frequent stresses and trauma affecting this anatomic location. Tendons generally are best evaluated on short axis axial images of the foot or axial images of the ankle where the tendons are depicted in cross section. Other imaging planes may help to substantiate findings in tendons, but do not show the tendons to greatest advantage because the tendons, with the exception of the Achilles tendon, run obliquely to these planes.
How X-Rays Work
- X-rays, like light, are a form of electromagnetic radiation. Unlike visible light, however, x-ray radiation is powerful enough to pass through the human body. The process of medical x-ray imaging (known as medical radiography) uses film—or more often nowadays, a digital sensor—that is sensitive to x-ray radiation in the same way that conventional photographic film i…
What X-Rays Can Tell Your Doctor
- An x-ray image can tell your doctor whether a bone has been broken or fractured, or whether a joint has been dislocated. If you have a broken or fractured bone in your foot or ankle and need to wear a cast for a few weeks, x-rays will also be taken after the cast comes off in order to make sure that the bone has healed correctly and is properly aligned. X-rays can also detect tumors—…
Are X-Rays Dangerous?
- In the late nineteenth and early twentieth centuries, when x-ray technology was brand new, doctors and scientists did not understand that exposure to radiation could be dangerous, and doctors and x-ray technicians subjected patients to frequent and dangerous doses of radiation, sometimes with deadly results. Over time, however, doctors came to better understand the dang…
What to Expect During Your Foot X-Ray Procedure
- Before the x-rays are taken you will be asked to take off your shoes and socks and roll up the legs of your pants. You will need to remove any jewelry or metal objects you may be wearing—for example, an ankle bracelet or toe ring. If you are pregnant, you must let the doctor know before allowing yourself to be exposed to x-rays. Developing fetuses ...
