Sementløs

Sementløs is a Norwegian term that translates to "cementless" in English. It is most commonly used in the context of orthopedic surgery, specifically in the implantation of prosthetic joints such as hip or knee replacements. A cementless prosthesis is designed to be fixed directly to the bone without the use of bone cement. Instead, these implants typically have a porous or textured surface that encourages the patient's own bone to grow into and anchor the implant over time. This process is known as osseointegration.

The advantage of cementless implants is that they can potentially offer a longer lifespan compared to cemented implants. As bone cement can degrade over time and lead to loosening of the prosthesis, cementless designs aim to circumvent this issue by relying on biological fixation. This can be particularly beneficial for younger, more active patients who are likely to put more stress on the artificial joint over many years. However, the success of cementless implants depends heavily on the quality of the patient's bone and the surgical technique.

The decision to use a cementless or cemented prosthesis is made by the orthopedic surgeon based on various factors, including the patient's age, activity level, bone density, and the specific type of surgery being performed. While cementless implants have become increasingly popular, cemented options remain a viable and effective choice for many patients.
