How does an acetabular fracture happen?
Acetabular fractures are usually caused by either high-energy trauma, most commonly from an automobile accident, or from what is called an insufficiency fracture. An insufficiency fracture is most common in older patients and is caused by the bone being weakened by osteoporosis.
What is the pathophysiology of hip fracture?
hip fracture, in pathology, a break in the proximal (upper) end of the femur. Related Topics: joint joint disease fracture hip. See all related content → Hip fracture can occur at any age. Common causes include severe impact (e.g., a car accident), falls, and weak bones or bone loss (osteoporosis).
Is acetabular fracture a hip fracture?
An acetabular fracture is a break in the socket portion of the “ball-and-socket” hip joint. These hip socket fractures are not common — they occur much less frequently than fractures of the upper femur or femoral head (the “ball” portion of the joint).
What is the function of the fovea capitis?
The femoral head is the most proximal portion of the femur and is supported by the femoral neck. It articulates with the acetabulum of the pelvis. The femoral head is nearly spherical (two-thirds) but has a medial depression known as the fovea capitis femoris that serves as an attachment point for the ligamentum teres.
Is a fracture a pathology?
A pathologic fracture is a break in a bone that is caused by an underlying disease. At the Spine Hospital at the Neurological Institute of New York, we specialize in pathologic fractures of vertebrae, or bones of the spine. For the most part, bones need a reason to break–for example, a significant trauma.
How do you immobilize a hip fracture?
Hip fractures usually require surgical realignment to secure the bone fragments together. This is completed with hardware such as nails, pins, screws, and/or plates. After surgery, your leg will be immobilized for approximately six to eight weeks, depending on the break. Crutches or a walker will be needed to walk.
What is fovea femur?
The fovea capitis is a small, oval-shaped dimple on the ball-shaped end (head) on top of your femur (thigh bone). It fits into a cup-shaped “socket” called the acetabulum in the lower part of your pelvic bone. Together, the femoral head and acetabulum make up your hip joint.
What artery supplies the femoral head?
The majority of the blood supply to the head of the femur comes from the medial and lateral circumflex branches of the profunda femoris, which itself is a branch of the femoral artery (the profunda femoris is the deep penetrating branch of the upper thigh).
