![]() ![]() There are also a number of risk factors that increase your chances of getting a hairline fracture: Who’s most at risk for developing a hairline fracture? navicular, a bone on the top of the midfoot.It’s also common to experience a hairline fracture in your: This is because they’re thin bones and the point of impact when pushing off on your foot in order to run or jump. Within the foot, the second and third metatarsals are most commonly affected. These bones absorb a lot of stress during running and jumping. The bones of the foot and leg are especially prone to hairline fractures. Not allowing yourself enough time to heal between activities is often a factor in the probability of getting this injury. ![]() Hairline fractures are often caused by overuse or repetitive actions when microscopic damage is done to the bone over time. People with osteoporosis can also develop hairline fractures. This injury is most common in athletes, especially athletes of sports that involve running and jumping. Treatment may involve applying ice to the affected area.Ī hairline fracture, also known as a stress fracture, is a small crack or severe bruise within a bone. If you think abnormal foot mechanics such as overpronation or over supination has contributed then see a physio or podiatrist to have orthotics (shoe inserts) fitted.A hairline fracture typically results from injury and can cause swelling and tenderness.For those whose job requires them to weight bear, a walking boot may be used to reduce the strain on the bones and soft tissues of the foot.This may confirm the presence of a stress fracture as it should show up as new bone growth at the point where the fracture occurred.The rest period should normally be around 4 weeks to allow sufficient healing, after which a second X-ray should be taken.Ideally, an X-ray should be taken at the beginning of the rest period.Continuing with normal training, especially weight-bearing activities will not allow the bone to begin to heal. Rest from weight-bearing activities as much as possible.This means it is rigid and does not pronate enough to absorb forces from running. Over supination – where your foot has a particularly high arch and rolls outwards.Overpronation – where your foot rolls in too much, or flattens.Repetitive strain on the bone eventually results in a stress fracture. Overuse! They are common in army recruits (often called a march fracture), runners, ballet dancers, and gymnasts.What causes a metatarsal stress fracture? Stress fractures in the other metatarsals are less common, although they do occur. As a result, this places a greater load on the 2nd metatarsal. This is because the first metatarsal bone is in a dorsiflexed (foot pointing upwards) position. It is also more common for those feet to roll in too much or flatten ( overpronate). The most location for a metatarsal fracture is the second metatarsal, especially in those whose second toe is longer than their big toe. They are the second most common location for a stress fracture in sport, after tibia stress fracture (shin). A stress fracture occurs gradually over time from repetitive strain or overuse, for example in long-distance runners.Ī metatarsal stress fracture most likely involves the second, third or fourth metatarsal bones.An acute fracture is caused by a direct impact or trauma such as being trodden on in football by a player wearing football boots with studs.Metatarsal fractures can be either acute fractures or stress fractures. The metatarsals are the long bones in the foot which connect the tarsal bones in the ankle to the phalanges bones of the toes. An X-ray will often not show the fracture until two or three weeks after it has started to heal.There may be a specific tender spot on the bone where the fracture is located. Symptoms are made worse with weight-bearing activities such as walking, running or dancing.Pain is usually located towards the middle, or front of the foot.Pain in the forefoot that develops gradually over time. ![]() Symptoms of a metatarsal stress fracture include: Medically reviewed by Dr Chaminda Goonetilleke, 20th Jan. The second metatarsal is the bone most commonly injured. They occur through overuse or poor foot biomechanics. A metatarsal stress fracture is a hairline fracture in one of the long metatarsal bones in the foot. ![]()
