The femur or thigh bone is the longest and strongest bone in the body, connecting the hip to the knee. A femur fracture is a break in the femur. The distal femur is the lower part of the thigh bone which flares out like an upside-down funnel and its lower end is covered by a smooth, slippery articular cartilage that protects and cushions the bone during movement. Fracture of the distal femur may involve the cartilaginous surface of the knee as well and result in arthritis.
The hip joint is a “ball and socket” joint. The “ball” is the head of the femur or thighbone, and the “socket” is the cup-shaped acetabulum. The joint is surrounded by muscles, ligaments, and tendons that support and hold the bones of the joint in place. Hip dislocation occurs when the head of the femur moves out of the socket. The femoral head can dislocate either backward (posterior dislocation) or forward (anterior dislocation).
A hip fracture is a break that occurs near the hip in the upper part of the femur or thighbone. The thighbone has two bony processes on the upper part - the greater and lesser trochanters. The lesser trochanter projects from the base of the femoral neck on the back of the thighbone. Hip fractures can occur either due to a break in the femoral neck, in the area between the greater and lesser trochanter or below the lesser trochanter.
The hip joint is one of the most important and flexible joints in the human body which allows us to walk, run, bend and perform physical activities. It is a ball (femoral head) and socket joint formed between the hip bone and femur (thighbone). It is surrounded by strong muscles and tough ligaments that prevent its dislocation.
The hip plays an important role in supporting your upper body weight while standing, walking and running, and hip stability is crucial for these functions. The femur (thighbone) and acetabulum (socket-shaped region of the pelvis) join to form the hip joint, while the labrum (rim of tissue that seals the hip joint) and the ligaments lining the hip capsule maintain the stability of the hip.
Injuries to the hip ligaments are commonly called a hip sprain and can range from minor tears of the ligaments to more serious injuries involving the hip muscles, tendons or bone.
A hip labral tear is an injury to the labrum, the cartilage that surrounds the outside rim of your hip joint socket.
