Bell's palsy is characterized by a one-sided facial droop that comes on within 72 hours. The facial nerve controls a number of functions, such as blinking and closing the eyes, smiling, frowning, lacrimation, salivation, flaring nostrils and raising eyebrows.
A hip fracture is a break in the upper quarter of the femur (thigh) bone. The extent of the break depends on the forces that are involved. The type of surgery used to treat a hip fracture is primarily based on the bones and soft tissues affected or on the level of the fracture.
During running and other high-impact activities, the hip joint absorbs some of the greatest forces in the body. Repeated high-impact activities and overuse can result in a stress fracture of the hip. A stress fracture is a break in the bone that occurs when minor injuries to the bone build up beyond the capacity of the bone to repair itself. Stress fractures of the hip are critical to diagnose and treat quickly because without treatment, they can lead to severe damage to the hip joint, even in young athletes.
