Total Hip Replacement
The decision to have a Total Hip Replacement surgery should be a cooperative one made by you, your family, your primary care doctor, and your orthopedics surgeon. Total hip replacement (also called total hip arthroplasty), the damaged bone and cartilage is removed and replaced with prosthetic components.
Candidates for Surgery: there are no absolute age or weight restrictions for total hip replacements. Recommendations for surgery are based on a patient's pain and disability, not age. Most patients who undergo total hip replacement are age 50 to 80.
There are several reasons why your doctor may recommend hip replacement surgery. People who benefit from hip replacement surgery often have:
- Hip pain that limits everyday activities.
- Hip pain that continues while resting.
- Stiffness in a hip that limits the ability to move or lift the leg
- Inadequate pain relief from anti-inflammatory drugs.
Patients do have arthritis of the hip are candidates for either traditional total hip replacement (arthroplasty) or hip resurfacing (hip resurfacing arthroplasty). Each of these procedures is a type of hip replacement, but there are important differences. In a traditional total hip replacement, the head of the thighbone (femoral head) and the damaged socket (acetabulum) are both replaced with metal or ceramic components. In hip resurfacing, the femoral head is not removed, but is instead trimmed and capped with a smooth metal covering. The damaged bone and cartilage within the socket is removed and replaced with a metal shell, just as in a traditional total hip replacement.
Partial Hip Replacements
If only one part of the joint is damaged or injury, a partial hip replacement is recommended for you. In most instances, the acetabulum is left intact and the head of the femur is replaced, using components similar to those used in a total hip replacement. The most common form of partial hip replacement is called a bipolar prosthesis. Partial hip replacement could give the younger patient some time before they have to resort to a total replacement. However, the bony socket does not always do well bearing on a metal prosthesis, which can cause some erosion of the bone resulting in a thinning of the floor of the socket.
Hip Replacements Complications
As with any surgical procedure, there are risks involved with hips replacements. Your surgeon will discuss each of the risks with you and will take specific measures to help avoid potential complications.
- Injury to nerves or vessels.
- Femoral neck fracture.
- Risks of anesthesia.
A hip fracture is a break in the upper quarter of the femur (thigh) bone. Causes Hip fractures most commonly occur from a fall or from a direct blow to the side of the hip. Medical conditions such as osteoporosis, cancer, or stress injuries can weaken the bone and make the hip more susceptible to breaking.
Types of Fractures
- Intracapsular Fracture
- Intertrochanteric Fracture
- Subtrochanteric Fracture
- Discomfort with any attempt to flex or rotate the hip
- The leg may appear to be shorter
- The diagnosis of a hip fracture is generally made by an X-ray of the hip and femur
