Degenerative hip diseases affect millions of people around the world. These diseases cause pain and significant limitations in their daily lives. One possible method of treatment is the replacement or replacement of the joint with a prosthesis. This type of surgical procedure is known as a hip replacement. Every year, hundreds of thousands of people experience pain relief and regain joint mobility after such an operation.
What is a hip replacement?
The hip prosthesis is a set of components made of metal, plastic or porcelain, whose purpose is to replace the joint, thereby eliminating pain and improving mobility.
Types of hip replacement
We can order the types of prostheses in terms of the type of joint if the replacement is one or more pieces. Another possible distribution would be to take into account the type of fixation they use. Here are both classifications:
If we look at the type of joint:
When only the femoral head is replaced, we call that procedure a partial arthroplasty. Its main indication is femoral neck fractures in the elderly. This type of arthroplasty is not used in cases of degenerative disease.
When the two components of the joint (femur and pelvis) are replaced, we call this procedure a total arthroplasty.
According to the fixation of the prosthetic components:
- Cemented prostheses: these are prostheses that need a bone cement to hold them to the bone. They are usually used in patients with osteoporosis.
- Uncemented: these are prostheses that do not need a bone cement to fix them to the bone because they have a porous surface, which promotes bone growth around the prosthesis. This process is called osseointegration.
Hip replacement materials
A hip replacement is made up of the following components:
- Stem that is always metallic. It can be made of titanium, stainless steel (little used) or a Cobalt-Chromium alloy
- Head, can be metallic (Cobalt-Chrome) or ceramic
- Insert, can be made of polymer (polyethylene) or ceramic
- Acetabular component of the same material as the stem, always metallic (stainless steel, titanium or Cobalt-Chrome alloy)
Sometimes, after a few years of a hip replacement, a replacement of the prosthesis is necessary. In these cases, a revision prosthesis is used.
How is the recovery from hip replacement surgery in Vadodara?
It depends a lot on the previous clinical conditions of the patient. It is usually possible to walk the second day after surgery. However, it is vitally important that the patient perform physiotherapeutic exercises for rehabilitation after a hip replacement.
