OBJECTIVES: Femoro-acetabular impingement may be a risk factor for hip osteoarthritis in men. The underlying hip deformity of the cam-type is common in asymptomatic males with non-dysplastic hips. We examined whether hip deformities of the cam-type are associated with signs of hip pathology, including labral lesions and damage of articular cartilage, on magnetic resonance images (MRI). METHODS: In this cross-sectional, population-based study in young asymptomatic male individuals, 1080 subjects were included, underwent clinical examination and completed a self-report questionnaire. 244 asymptomatic males with a mean age of 19.9 years received MRI. All MRIs were read for cam-type deformities, labral lesions, signs of cartilage and impingement pits. The relationship between cam-type deformities and signs of joint damage were examined using logistic regression models adjusted for age and body mass index. RESULTS: Sixty-seven definite cam-type deformities were detected. These deformities were associated with labral lesions (adjusted odds ratio [OR] 2.77, 95% confidence interval [CI] 1.31 to 5.87), impingement pits (adjusted OR 2.9, 95% CI 1.43 to 5.93) and labral deformities (adjusted OR 2.45, 95% CI 1.06 to 5.66). The adjusted mean difference in combined antero-superior femoral and acetabular cartilage thickness was -0.19mm (95% CI -0.41 to 0.02) lower in those with cam-type deformities compared to those without. CONCLUSIONS: In young asymptomatic men, the presence of a cam-type deformity was associated with MRI detected hip damage. |
