The Anatomy of Your Hip

The hip is one of your body's largest weight-bearing joints. It consists of twomain parts: a ball (femoral head) at the top of your thigh bone (femur) and a rounded socket (acetabulum) in your pelvis.

The top of your femur is categorized into four main parts: the subtrochanteric region near the bottom of the hip joint, the intertrochanteric region in the middle of the joint, the greater trochanter at the top of the joint, and the femoral neck that connects the femur to the femoral head. These regions are show in the image below.

Hip fractures occur in three main areas:


  • Femoral neck
  • Intertrochanteric region
  • Subtrochanteric region

Types of Surgeries

The type of surgery you have depends largely on where your fracture has occurred. Some common procedures to repair hip fractures are described below.



Hemiarthroplasty (partial joint replacement)

This is a common procedure performed on patients who have a femoral neck fracture. During this surgery, the broken ball of the hip is removed and replaced with a high-strength artificial ball. The images to the right shows an example of the artificial device and where it is placed in the hip. An Austin Moore implant, a type of endoprosthesis, is the implant sometimes used in older patients with femoral neck fracture who are less active or nonambulatory. It holds the advantage of less blood loss and operative time.


Open Reduction Internal Fixation

This is normally used for stable femoral neck fractures. In this type of treatment, the surgeon repositions (reduces) the bone fragments into their normal alignment, then inserts screws or attaches metal plates to the outer surface of the bone to stabilize the fracture.


 Trochanteric Fixation Nail

This is commonly used for intertrochanteric and subtrochanteric fractures.



Total Hip Replacement Surgery

This surgery involves replacing all of the joint with artificial (usually metal) parts. A total hip replacement can be done if the hip joint area was already damaged before the fracture by arthritis or an injury and the joint was not working correctly. Total hip replacement is often done for femoral neck fractures when the blood supply to the top of the thighbone is damaged and there is a chance that the bone might die (avascular necrosis). It is also done when the fractured bones cannot be properly aligned.
