Cemented/Uncemented Hip Replacement

The method by which the prosthetic implant is secured to the native bone varies between cemented and uncemented hip arthroplasties. Bone cement is used in a cemented hip arthroplasty to secure the implants to the bone interface. Hip replacements without cement rely on bone development rather than specialised implants.

They came to the conclusion that in primary THAs, cemented fixation demonstrated a generally greater long-term survivability than cementless fixation. In particular, cement-fixed fixations outlasted cementless fixes in younger patients while cement-fixed fixes outlasted cementless fixes in older patients. A surgeon can attach prosthetic joint components to a bone that has a little amount of osteoporotic pore structure using bone cement. The risk of postoperative infection can be reduced by a little amount of antibiotic material being incorporated into the bone cement.

In a number of findings presented at a meeting of orthopaedic surgeons held here, doctors stated that cementless hip replacements appear to hold up well in both young and senior patients. Most patients who received the devices have stable, pain-free implants, some for as long as 15 years, according to long-term follow-up studies.
