Why do some hips hurt? scientists investigate hidden clues in movement and spine shape
NCT ID NCT06272292
First seen Jun 24, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study looks at young men with a hip condition called femoroacetabular impingement (FAI), where extra bone growth causes pain during movement. Researchers will use 3D motion analysis and low-dose X-rays to compare how the hip and spine move in people with and without symptoms. The goal is to uncover why some people with the same bone shape feel pain while others do not, which could lead to better diagnosis and treatment.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- What this could lead to
- If successful, this could help doctors better understand why some people with hip shape abnormalities develop pain while others do not, potentially improving diagnosis and treatment.
- What could go wrong
- This is an observational study, not a treatment trial. It will not test any therapy, so it cannot directly lead to a cure or symptom relief. Results may not apply to women or older adults.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.
Exclusion Criteria: \- Participants in all three study groups will be excluded if x-ray scans shows a pincer FAI morphology or radiological sign of osteoarthritis. Inclusion Criteria: * All participants will be males aged between 21 and 35 years old. * For symptomatic CAM-FAI patients 1. The presence of CAM-FAI morphology at the head-neck junction of the femur 2. Alpha angle \>60 3. Reduced hip internal rotation (IR\<15) * For asymptomatic CAM controls: 1\. Exhibit asymptomatic CAM on x-ray scansAlpha angle \>60 * For Healthy control group: 1. Exhibit no symptoms or abnormal morphologies of the proximal femur (Alpha angle \>60 , IR\>15).
