Hairline fractures, also called stress fractures, are tiny cracks in bone that occur with repetitive or excessive force. Forceful activities that can lead to hairline fractures include running, basketball, and tennis. The term “hairline fracture” can be misleading because these types of fractures are not always visible on an X-ray.
A hairline fracture may not cause any pain initially. However, as the crack begins to grow, pain may develop. The pain is usually worse with activity and relieved with rest. You may also notice swelling and tenderness around the injured area.
If you suspect you have a hairline fracture, it’s important to see a doctor right away. If the fracture is not treated, it can lead to a more serious injury, such as a complete break. Treatment for a hairline fracture usually involves rest and avoiding activities that put stress on the bone. In some cases, your doctor may recommend wearing a splint or cast. If the fracture is severe, you may need surgery. A hairline is the natural line that delineates the border of the hair on the scalp.
The purpose of the hairline is to protect the scalp from sun and other environmental damage. It also provides a frame for the face and can be a distinguishing feature. For example, a widow’s peak is a V-shaped point in the hairline in the center of the forehead.
A hairline is the natural border of the hair on the forehead. It is considered an important part of facial aesthetics, and a high, well-defined hairline is often associated with youth and attractiveness. A receding or irregular hairline can cause anxiety and may be a sign of underlying health problems. There are a number of treatments available to improve the appearance of the hairline, and in some cases, surgery may be an option.
