![]() Posterior malleolus fractureĪccording to a 2016 review, a posterior malleolus fracture occurs on the back of the tibia. Bimalleolar equivalent fractureĪ bimalleolar equivalent fracture means that in addition to one of the malleoli being fractured, the ligaments on the inside of the ankle are injured. It’s the second most common type of ankle break. Based on a 2022 review, these almost always require surgery to repair. Bimalleolar ankle fractureĪ bimalleolar ankle fracture involves both knobs in the ankle, which include the fibula (lateral malleolus) and tibia (medial malleolus). A 2019 review indicates that it specifically affects the medial malleolus, which is the knob on the inside of your ankle. Medial malleolus fractureĪ medial malleolus fracture happens at the end of the tibia. On the other hand, with a nondisplaced fracture, the broken bones remain in the correct position and retain their usual structure. With a displaced fracture, fragments of the bones that are broken may be separated or misaligned. Penn Medicine says that ankle fractures are often categorized as either displaced or nondisplaced. Lateral malleolus fractures are the most common type of ankle break. It involves the bony “knob” outside of your ankle called the lateral malleolus, according to a 2019 study. This break occurs at the bottom of the fibula. According to the Hospital for Special Surgery, types of ankle break injuries include: Lateral malleolus fracture The type and severity of an ankle break depends on the amount of force that caused it. This could be caused by a heavy object falling on the foot or heavy machinery running over the ankle. Intense force to the ankle can cause crush injury and fracture. This type of injury is often seen in runners and other athletes. BIMALLEOLAR FRACTURE CRACKRepetitive force or trauma to the ankle can cause a stress fracture, which is a small crack in the bone. Often, these injuries need surgical repair. The sudden, heavy impact of a car accident can cause broken ankles. Examples of high impact sports include soccer, football, and basketball. High impact sports involve intense movements that place stress on the joints, including the ankle. Your ankle might twist or roll to the side as you put weight on it. You can break your ankle if you put your foot down awkwardly. It can happen even if you jump from a low height. The force of a jump or fall can result in a broken ankle. This might happen if you walk on an uneven surface, wear ill-fitting shoes, or walk around without proper lighting. Losing your balance may lead to trips and falls, which can place excessive weight on your ankle. It can also see tears in the ligaments.Ī broken ankle occurs when too much force is placed on the ankle. It can help the doctor find fractures that don’t show up on X-rays. An MRI scan uses a magnetic field and radio waves to show the bones and surrounding tissue. A CT scan provides more detailed images by taking multiple cross-sectional pictures of the ankle. If the joint opens up, this indicates a grade 3 tear that may need to be repaired. A doctor will place pressure on the ankle and take an X-ray. A stress test determines if a sprained ankle needs surgery. An X-ray lets a doctor see the location, type, and severity of the break. They might also move your foot around to determine your range of motion. If tenderness is over the bone, it’s most likely a fracture. If there is tenderness over a ligament, the injury is most likely a sprain. The doctor will examine your ankle for swelling and tenderness. To diagnose your injury, your doctor will do different tests. The only way to determine if there is a fracture or sprain is to visit a doctor. You may or may not have severe bruising and swelling. It depends on the type and cause of the fracture (a motor vehicle accident versus a fall, for example). Right after breaking an ankle, you may or may not be able to walk or place weight on the ankle. You may or may not be able to put weight on your ankle just after the injury.Ī broken ankle can be just as painful as, if not more painful than, a sprain. The type of sprain will determine the degree of pain and swelling: a grade 1 sprain will have a little swelling, but a grade 3 sprain may have significant swelling. If your ankle is sprained, you’ll have pain and swelling. ![]() Ligaments are tough tissue that connects one bone to another. ![]() A sprained ankle happens when ligaments tear or stretch. sprained ankle symptomsĪ broken ankle isn’t the same as a sprained ankle. ![]()
