What is uncemented & cemented hip replacement?

Published on 06 Mar, 23

A total hip replacement surgical procedure is basically one of the best and most effective treatments to get relief from hip pain as well as improve your hip function. Now, several hip arthroplasties are uncemented hip replacements because they have better and long-term results.

During hip replacement surgery, an artificial joint is placed inside the canal of the upper portion of the thigh bone. Cemented and uncemented hip replacements are different in how the prosthetic implantation is fixed to the natural bone. A cemented hip replacement depends on the bone cement for fixing the implantation to the bone interface, while uncemented hip replacement relies on bone on-growth over particularly designed implantations.

Cemented Hip Replacement

A cemented hip replacement is a process that uses a polymethylmethacrylate (PMMA) bone cement – that is made by mixing powder and liquid components for fixing the implantation surface to the bone. The bone cement that is used during cemented hip replacement helps to create a grout and fixes the implantation by acting as an interlocking surface between the implant and the bone.

Uncemented Hip Replacement

This hip replacement process basically uses specially designed prosthetic components for bone-to-implant fixation. This is also one of the most common hip replacement methods that are used frequently. During uncemented hip replacement, a few screws are used for securing the acetabulum shell in the right place. This is one of the preferred choices for aged people.

Cemented vs. Uncemented Process

Which type of fixation is basically used in hip replacement depends on the patient’s individual hip anatomy, age, and the patient’s medical history. Even though the cemented procedure is accomplished at the immoderations of age, the patients for cemented fixation may be the ideal candidate for uncemented fixation based on their bone stock.
