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.
The hip joint is a ball and socket joint. The socket part is lined with smooth cartilage and is called the acetabulum, which is part of the pelvis. When the socket is fractured, it is called an acetabular fracture. Such fractures are far less common than fractures to the ball part of the joint.
