Description
Aims
Femoroacetabular impingement (FAI) has been highlighted and well documented primarily in Western countries and there are few large studies focused on FAI‐related morphological assessment in Asian patients. We chose to investigate this subject.
Patients and Methods
We assessed the morphology of the hip and the prevalence of radiographic FAI in Japanese patients by measuring predictors of FAI. We reviewed a total of 1178 hips in 695 men and 483 women with a mean age of 58.2 years (20 to 89) using CT images that had been obtained for reasons unrelated to symptoms from the hip. We measured the lateral centre edge angle, acetabular index, cross‐over sign, alpha angle, and anterior femoral head‐neck offset ratio.
Results
A total of 441 hips (37.4%) had pincer‐type deformity (41.7% men, 31.3% women) and 534 (45.3%) had cam‐type deformity (54.4% men, 32.3% women). Moreover, 773 hips (65.6%) had at least one parameter that predisposes to FAI (74.0% men, 53.6% women) and 424 hips (36.0%) had two or more parameters (43.6% men, 25.0% women).
Conclusion
The prevalence of radiographic FAI was common in Japanese patients who are generally considered to have dysplastic hips.
