Three-dimensional magnetic resonance imaging analysis of hip morphology in the assessment of femoral acetabular impingement
چکیده انگلیسی

AimTo determine a possible association between femoral–acetabular impingement (FAI) volume and the development of labral tear using a three-dimensional (3D) model reconstruction of the acetabulum and the femoral head.Materials and methodsMagnetic resonance arthrography images of the hip in 42 patients with pain and suspected labral tear were acquired using a 1.5 T MRI machine. Using 3D analysis software, outlines of the acetabular cup and femoral head were drawn and 3D reconstruction obtained. To control for differences in patient size, ratios of acetabulum : femoral head volume (AFV) and acetabulum : femoral head surface area (AFA) were used for analysis. The association between volume of acetabulum : femoral head and FAI was investigated using ANOVA analysis.ResultsThere were 19 men and 23 women with a mean age of 39 years (range 18–78 years). The average AFV was 0.64 (range 0.37–1.05, SD 0.16) and AFA was 0.73 (range 0.36–1.26, SD 0.23). Herniation pit was significantly associated with a small AFV.ConclusionFemoral neck herniation pits are associated with a low AFV. Gross volume and surface area ratios do not appear to correlate with labral tears or cartilage loss. This technique will enable more advanced analysis of morphological variations associated with FAI.
