Anterior Total Hip Replacement

Total hip replacement (arthroplasty) is an operation designed for the treatment of advanced arthritis of the hip. Hip replacement can also be performed for other hip conditions such as osteonecrosis (avascular necrosis) of the hip, hip fractures, post-traumatic arthritis, and childhood hip diseases.

There are many different surgical approaches to expose the hip joint. Historically, the operation was done through a posterior or lateral approach to the hip. When the operation is performed through the anterior approach, it can be minimally invasive and muscle-sparing in that it does not involve cutting any muscles around the hip, unlike the posterior or lateral approaches to the hip. When one can avoid cutting any muscles around the hip, the hip joint and implants remain inherently more stable. After exposing the hip, special instrumentation is used to efficiently and securely implant metal and plastic components to replace the hip joint.

Potential benefits of the minimally invasive anterior approach include lower dislocation rates, fewer post-surgery restrictions, less pain, better mobility, shorter hospital stays, and less tissue disruption, which leads to faster rehabilitation. Dr. Rana also uses live x-ray (or fluoroscopy) during the surgery to ensure accurate placement of the implants. This imaging technology during the anterior-approach allows him to more consistently restore equal leg lengths and the native offset of the hip, which leads to a more natural feeling hip. This also results in lower dislocation rates, less pain, and a faster recovery.

This procedure is increasingly being done on an outpatient basis with potential benefits including lower risk of hospital-acquired infections, greater patient satisfaction, and faster recovery at home.

5 Signs you May Benefit From a Hip Replacement

A healthy hip joint has adequate space between the head of the femur and the socket (acetabulum). On the pre-op x-ray, the hip on the right of the xray (which is the patient’s left hip) shows signs of severe arthritis including obliteration of the joint space (bone on bone), sclerosis (increased density and thickening of the bone), and osteophytes (bone spurs). The post-op x-ray, shows the patient after a left total hip replacement.

On the pre-op x-ray, the images shows signs of severe arthritis involving the right hip including obliteration of the joint space, sclerosis, and osteophytes.  The post-op x-ray, shows the patient after a right total hip replacement.
