case_images: Pelvis AP (A), Frog-leg (B) and close view (C) of the right hip in the Frog-leg view radiographs. Note an osteochondral fragment in the central part of the femoral head. In the Frog-leg view, the fragment appears to be detached from its bony base.

case_images: Radiographs showed a possible loose osteochondral fragment inside the joint, detached from the central part of the femoral head (Figure 1).
case_images: Magnetic Resonance Images (MRI) of both hips in the coronal view. A. T1-weighted MRI showing a non-perfused area surrounding the osteochondral fragment. B. T2-weighted MRI showing intra articular synovitis and edema around the OCD fragment. Note that the articular cartilage has a step-deformity due to a slight elevation of the unstable OCD fragment.

case_images: The contrast-enhanced magnetic resonance imaging (MRI) showed an unstable osteochondral fragment measuring 28 x 22 mm with surrounding bone edema (Figure 2).
