New hip stem holds promise for patients with wide thigh bones
NCT ID NCT06768541
First seen Jun 26, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study looked at how well a short stem hip replacement stays in place in people with a wider thigh bone canal (DORR Type C). 108 participants who had this surgery were followed to measure any sinking of the implant and to track their pain and function. The goal was to see if this type of stem is a good option for this specific bone shape.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Short stem hip replacement (Optimys short stem)
- What this could lead to
- If successful, this could show that short stem hip replacements are a good option for people with a wider thigh bone canal, potentially leading to better long-term implant stability.
- What could go wrong
- This is a small, completed study with no control group, so results may not apply to everyone. The main risk is that the implant may shift (subside) over time, which could require further surgery.
