Arthroplasty or Hip Prosthesis

Posted by

Hip arthroplasty , or placement of a total hip replacement, involves replacing a diseased hip with an artificial joint.

This is one of the most reliable interventions of orthopedic surgery.

The purpose of this surgery is to relieve the pain and improve the mobility of the damaged joint. It can allow you to resume activities that were no longer feasible with the sick hip.

The placement of a prosthesis by a hip surgeon is discussed after failure of medical treatment (analgesics, anti-inflammatory). Its indication is based on several arguments: pain, major functional discomfort (stiffness and decrease in the perimeter of walking), and radiographic confirmation of joint damage (pinching of the line).

A preoperative assessment will then be necessary: ​​consultation with an anesthetist, dental assessment, biological analyzes …

The total hip prosthesis consists of several elements:

  • a cup that may be made of metal, polyethylene, or ceramic and will be attached to the acetabulum (articular surface on the side of the pelvis).
  • a metal rod fixed in the femur which has a head whose diameter and material vary according to the indications.


The implants are biocompatible which means they are manufactured to be accepted by your body, they are made to withstand corrosion, degradation and wear. You can get information about Marie Napoli’s hip recall lawsuit for material used in the hip implantation.

The choice of the material of each implant depends on your age, your morphological characteristics, your activities … so each patient benefits from a specific care.

All our implants are used routinely and have a validated reliability. Our decisions make it possible to obtain the best theoretical durability of your prosthesis.

The procedure lasts 45 to 60 minutes and requires hospitalization of about 3 days.

The approach, ie the incision made by the surgeon, depends on the deformity of the hip and your morphology. We favor anterior-lateral (Hueter) or antero-lateral (Rottinger) minimal invasive pathways, which have the advantage of not cutting any muscle and therefore allowing faster recovery. They also significantly reduce the risk of dislocation.

If the deformities are important it is also possible to carry out the installation of a prosthesis with assistance by computer.

During surgery , the patient can get up on the day of the operation, the drainage is not systematic. The resumption of the walk is immediate and is done with the help of canes that will be gradually abandoned with the physiotherapist.
