Do screws make hip replacements last longer?
NCT ID NCT06499038
First seen Aug 14, 2026 · Last updated Aug 14, 2026
Summary
This trial tests whether adding screws to secure the cup part of a hip replacement makes a difference in how well the implant stays in place. Participants aged 65-80 with hip osteoarthritis will receive a hybrid hip replacement, and half will get screws while the other half won't. Using advanced CT imaging, the study tracks implant movement over time to predict long-term survival. The goal is to see if screws are necessary or if the press-fit cup alone is enough.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
- Active substance
- Total hip arthroplasty (surgery) with or without ancillary acetabular screws
- What this could lead to
- If successful, this could help surgeons decide whether screws are needed for hip implants, potentially improving long-term implant survival and reducing complications.
- What could go wrong
- This is a small, early-stage trial with 60 participants, so results may not apply to all patients. There are standard surgical risks like infection, implant loosening, or complications from anesthesia.
