Early diagnosis and targeted intervention based on the pathogenesis of rapidly progressive osteoarthritis of the hip

Figure 2 Right hip joint with rapidly progressive osteoarthritis of the hip demonstrating partial destruction of the anterior portion of the femoral head on computed tomography at 6 months after the onset subsequent to rapid chondrolysis. Magnetic resonance imaging at 4 months after the onset shows high intensity on the short τ inversion recovery sequence image in the proximal femur, including the femoral neck and head. CT: Computed tomography; MRI: Magnetic resonance imaging.
