Cam-Type Deformities Linked to MRI-Detected Hip Damage
MRI detects labral lesions, impingement pits, labral deformities in asymptomatic males
MONDAY, Sept. 12 (HealthDay News) -- In young asymptomatic males, magnetic resonance imaging (MRI) detects cam-type deformities associated with labral lesions, impingement pits, and labral deformities, according to a study published online Sept. 8 in Arthritis & Rheumatism.
Stephan Reichenbach, M.D., from the University of Bern in Switzerland, and colleagues examined whether hip deformities of the cam-type are associated with signs of hip pathology, including labral lesions and damage of articular cartilage, on MRI. A total of 1,080 young, asymptomatic male individuals underwent clinical examination, and completed self-reported questionnaires. Of these, 244 asymptomatic males (mean age, 19.9 years) underwent MRI that was assessed for cam-type deformities, labral lesions, signs of cartilage, and impingement pits. Logistic regression models adjusted for age and body mass index were used to examine the relationship between cam-type deformities and signs of joint damage.
The investigators identified 67 definite cam-type deformities. These deformities correlated with labral lesions, impingement pits, and labral deformities (adjusted odds ratio, 2.77, 2.9, and 2.45, respectively). The combined antero-superior femoral and acetabular cartilage thickness adjusted mean difference was −0.19 mm lower in individuals with cam-type deformities than in those without deformities.
"In young asymptomatic men, the presence of a cam-type deformity was associated with MRI detected hip damage," the authors write.
