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 number of annual hip fractures has been projected to surpass 500,000 annually by the year 2040. The fracture of a hip can lead to morbidity, a change in living arrangements, or death. One-year mortality rates of 12% to 36% have been reported.
