What Happens If an Ankle Fracture Is Not Treated?

If an ankle fracture is not treated, the bone may heal in the wrong position or fail to heal properly, leading to lasting pain, stiffness, instability, and difficulty walking. A fracture can also involve the joint surface or change the alignment of the ankle, which may place uneven stress on the joint over time. Symptoms such as [Ankle Pain](/symptoms/ankle-pain/) and [Ankle Swelling](/symptoms/ankle-swelling/) do not confirm a fracture by themselves, but after an injury they warrant assessment when they persist or are severe.

The ankle depends on accurate alignment so the bones and ligaments can share load during standing and walking. Without appropriate support, movement, or surgery when needed, broken bone fragments may shift. Healing in a changed position can affect how the foot meets the ground and may cause a limp, reduced movement, or repeated ankle giving-way. Some fractures do not join as expected, and pain may continue even when bruising has settled. Damage around the joint can also contribute to later [Ankle Osteoarthritis](/conditions/ankle-osteoarthritis/).

Trying to walk through an injury can worsen displacement or swelling. It may also hide the fact that the ankle needs protection. An X-ray, and sometimes additional imaging, helps clinicians judge the fracture pattern and choose suitable support.

Arrange prompt medical assessment after a significant ankle injury, especially if you cannot put weight through the foot. Until you are assessed, keep the ankle still, avoid walking on it, elevate the leg, and use a wrapped cold pack for short periods if this is comfortable. Do not try to straighten a visibly abnormal ankle or push a bone back into place.

Treatment depends on the location, alignment, and stability of the fracture. Options may include a [Walking Boot Immobilisation](/treatments/non-surgical-orthopedics/walking-boot-immobilisation/) or [Fracture Casting](/treatments/trauma-and-fracture-care/fracture-casting/). A displaced or unstable injury may need a procedure to restore alignment. Rehabilitation can help rebuild movement, strength, balance, and confidence once the bone is ready.

Seek urgent medical care for a [Visible Deformity After Injury](/symptoms/visible-deformity-after-injury/), an open wound near the suspected fracture, rapidly increasing swelling, severe pain, or skin that becomes pale, blue, or unusually cold. Numbness, new tingling, or inability to move the toes can indicate pressure or nerve and blood-flow problems. Go promptly as well if you have [Inability to Bear Weight](/symptoms/inability-to-bear-weight/) after the injury. Keep the foot supported while arranging help.

Even when the ankle looks fairly straight, ongoing pain, swelling, or tenderness over the bone should be checked rather than judged by appearance alone.

Ask where the fracture is, whether the bones are aligned, and whether the joint surface is involved. Clarify how much weight you may place on the foot, how the ankle will be protected, and which changes should trigger a review. Ask when movement should begin and whether [Post-Operative Rehabilitation](/treatments/physiotherapy-and-rehabilitation/post-operative-rehabilitation/) is appropriate if you have had surgery.
