Choosing Between Cemented, Uncemented Hip Prosthesis

It is often difficult to go about the daily activities because of the pain in the hips, health survey shows, but going through a hip replacement operation may be a way to decrease the pain and increase the mobility. Patients may have a cemented or cementless hip implant or even a combination of both. However, surgeons may still need to evaluate the condition of the patient and review the general guidelines on the type of fixation that the implant requires to be properly secured in place, according to the American Academy of Orthopedic Surgeons (AAOS). Nonetheless, patients may be able to ask their surgeons regarding the type of implant and the procedure if they have any questions.

In the past, orthopedic surgeons were able to keep the femoral and acetabular components in place by cementing them and technology paved way to much better cement. Cementing the prosthesis helps stabilize the hip and enables the patient to put on his or her full weight on the hip even after the surgical procedure. Those who have cemented hip implants were noted to have faster rehabilitation. Today, polymethylmethacrylate is the most commonly used cement for hip replacement surgery and keeps the implant in position for a long time but there were some patients who have experienced health complications because of this acrylic polymer.

Cementless hip prostheses were developed in the 80s. This type of implant was made to attach directly unto the bone and it helps in inducing the growth of new bone. However, unlike the cemented hip implants, patients who have this type of prosthesis may not be able to support their own weight immediately after the operation. They might need additional support such as canes and walkers until a specific time required by the surgeon. This allows the bone some ample time to attach to the implant and establish a strong bond. If this bone is not achieved, then it is possible that the implant may loosen over time.

The hybrid hip implant uses both cement and cementless components. The femoral stem may be inserted with the use of cement while the insertion of the acetabular socket is cementless. Researchers found that this type of implant promises better results but it still under observation. Although hip implants have made some of the lives of men and women with hip pain better, there were some who are rooting for a DePuy hip recall because of the damages that they have incurred.
