Also known as hip arthroplasty, hip replacement is a common orthopedic surgery common with advanced age and other conditions such as arthritis. This prosthetic procedure aims at alleviating pain as well as restoring ability and normal functioning of the hip for individuals whose hip joint has been destroyed by disease or trauma. In this procedure, the damaged or affected hip, composed of the hip socket and ball of the femur bone, is replaced by man-made hip implants.

Hip replacement can be done in two main approaches. There is the anterior and posterior hip replacement surgery New York has these days. Whereas other surgeons use the anterior approach, many prefer the posterior hip replacement surgery. So to say, the posterior approach is credited with excellent visibility of the affected joint and minimally invasive. Nonetheless, your choice of replacement approach depends on a myriad of factors. Arthritic damage, activity level, age, and weight are only a few to mention. Besides, finding the best New York orthopedic surgeon may help you make a choice.

What happens during the surgery?

During the replacement procedure, the damaged bone is primarily cut and removed with some soft tissues surrounding them. The removed part is then replaced with an implant that resembles and functions the same as the removed component of the hip. This can be done in two main ways where various components and surgical techniques are also used.

Types of replacement surgery

There are two main types of replacement surgery. They include:

  1. Total hip replacement

Here, the thigh bone (femur) and the head of the femur (ball) is removed and replaced with a new, similar artificial ball. To accommodate the new socket component, the surface of existing pelvis socket, also known as acetabulum, is roughened up. The artificial hip components are fixed to the bone with acrylic cement. However, new technology advancements allow for insertion without cement. When this is done, both surfaces, implant and acetabulum surface are roughened up and specially treated to encourage bone growth onto them.

Replacement parts can be made from plastic, metal or ceramic. Additionally, they can be used in varying combinations. Some of the common combinations include:

  • Metal on plastic – it is the most common and widely used combination where a metal ball is fitted with a plastic socket.
  • Ceramic on plastic – involves a ceramic ball with a plastic socket.
  • Ceramic on ceramic – occurs when both parts are ceramic. Often used in young and active patients.
  • Metal on metal – here, a metal ball is fitted with a metal socket. Occasionally used in young and active patients.
  1. Metal on metal hip resurfacing

This is quite different from replacement as it involves resurfacing the original socket and the ball of the bone. In this type, instead of removing the head of the thigh bone for replacement, a hollow metal cap is fitted over the head of the hip bone. Individuals who chose this type of knee revision surgery have reduced risks of dislocation compared to total replacement. Besides that, they also returned to a higher level of physical activity following the procedure.

The need of trying out replacement of hips can be present anytime. Being a critical procedure, finding the best surgeons for this procedure is crucial. This is why you should perhaps try visiting if you’re looking for surgeons.
