Fig. 2From: Does the optimal position of the acetabular fragment should be within the radiological normal range for all developmental dysplasia of the hip? A patient-specific finite element analysisThe generation of articular cartilage and 3D FE model of the hip. a A red filling layer was constructed in the joint space between the femoral head and acetabulum; the bisected part of this layer was taken as acetabular cartilage and femoral head cartilage. b The constructed acetabular cartilage. c The constructed 3D FE model of the femur and pelvis, the blue layer represents the articular cartilage and the purple line represents the spring elements simulating the capsular ligamentsBack to article page
