Mixed radiopacity defect at the origin of the long digital extensor tendon. Transverse CT slice (a) and 3D volume-reconstructed model (b) from the left distal femur of piglet 8 at the 6th examination interval. (a) The focal, mixed radiopacity defect is visible at the intersection of the solid green lines. The subchondral bone plate is intact and the defect is surrounded by a thin rim of sclerosis on all margins to bone. (b) The defect is located at the origin of the long digital extensor tendon in the distal third of the femoral lateral trochlear ridge (between arrows).
