In 30 seconds
This randomized controlled trial analyzed hip morphology in 119 individuals with femoroacetabular impingement (FAI) syndrome exhibiting cam morphology. The study found that 39% of participants had global retroversion of the acetabulum, while the prevalence of acetabular undercoverage and overcoverage was low, indicating potential underdiagnosis of pincer morphology.
Key findings
- 39% of participants exhibited global retroversion of the acetabulum.
- 9% had acetabular undercoverage and 9% had overcoverage based on W-CEA.
- Coxa valga was present in 27% of participants.
- The prevalence of hip dysplasia was low, ranging from 2 to 5%.
Why it matters
Understanding the various hip morphology phenotypes in FAI syndrome can aid clinicians in accurately diagnosing and managing patients, potentially improving treatment outcomes and preventing further joint damage.
