Fig. 1From: Magnetic resonance imaging follow-up can screen for soft tissue changes and evaluate the short-term prognosis of patients with developmental dysplasia of the hip after closed reductionThe labro-chondral complex classification. The labro-chondral complex was divided into 4 types (Coronal FS PDWI images), type 1 (a): normal (acetabular cartilage and labrum matches, the morphology of labrum is triangular and outward); type 2 (b): everted (mild hypertrophy of acetabular cartilage, the labrum is round and outward); type 3 (c): partially inverted (mild or moderate hypertrophy of the acetabular cartilage, the labrum inverted partially, which inserts between the femoral head and the acetabulum); type 4 (d): completely inverted (the labrum is inverted entirely and with significant cartilage hyperplasia)Back to article page
