Cemented Or Uncemented Hip Replacement Surgery
Uncemented
Choosing between cemented and uncemented hip replacement surgery involves a number of factors including age, health, and personal preference. Both methods are relatively safe, but there are differences in the outcome of both procedures. For example, cemented hip replacement procedures have a higher mortality rate than uncemented procedures. But, it is important to note that the differences in mortality rates between uncemented and cemented procedures are small. A number of factors can affect the mortality rate, such as the age of the patient, bone quality, and the amount of activity the patient is able to do after surgery.
The overall mortality rate in the uncemented group was about 7%. The survival rate for the patients with cemented procedures was slightly higher. However, the multivariable analysis revealed a higher mortality rate for cemented procedures. The cemented procedure was also found to have a lower revision rate than uncemented procedures. This may be because of the difficulty in evaluating patients with cemented implants.
Patients who are young are often better suited for uncemented hip replacement surgery. Younger patients need more movement in their hips and an uncemented hip replacement is easier to achieve this. This is because the acetabulum component of the hip is lined with a plastic and metal liner and inserted into the socket with bone cement. This method also reduces the amount of bleeding after surgery.
Another major difference between uncemented and cemented hip replacement procedures is the length of time before the patient experiences osteolysis. Although asymptomatic, if a severe bone loss occurs, it may cause complications in the future. If the patient experiences osteolysis, they may need a second surgery to restore the hip.
Uncemented hip replacement surgery is also associated with higher rates of bleeding, as there is no cement to prevent it from bleeding. The lack of cement also means that the prosthesis can wear out more quickly, requiring revision surgery. The uncemented group had a median follow-up of 2.6 years, compared to 3.6 years in the cemented group.
Uncemented hip replacement is best suited for patients with stronger bones and who are younger than middle-aged adults. The risks of hip replacement surgery include bleeding, infection, nerve and vessel damage, and thrombosis. It is also important to consider the patient’s physical activity level before surgery. If the patient is not physically active, it is more likely that their hip will fail within a short period of time. However, a combination of enhanced recovery techniques, such as early mobilization and an elevated toilet seat, can help to reduce the post-operative pain associated with hip replacement surgery.
The number of deaths is not high, but they are a significant concern. This is because patients who have uncemented hip replacement surgery are at increased risk for dislocation. There are a number of ways to prevent this, including avoiding combined movements and using grabbers to hold the new joint in place. Patients also may need to avoid crossing their legs. Lastly, patients should follow postoperative instructions carefully to prevent complications from bleeding or infection.
