Femoral head problems                                             

             ➢ Long bone necrosis                                                                            

             ➢ Femoral bone degeneration

             ➢ Proximal femur degeneration

             ➢ Femoral head degeneration

             ➢ Femoral head separation disorder

             ➢ Femoral head disarticulation

             ➢ Femoral head epiphysiolysis

             ➢ Femoral head necrosis

             ➢ Femoral head chondrosis

             ➢ Bacterial chondronecrosis

             ➢ Bacterial chondrosis & osteomyelitis

             ➢ Bacterial chondritis & osteomyelitis

             ➢ Osteomyelitis

          A: Femoral head with intact articular cartilage.

          B: Femoral head with separated articular cartilage, and the growth plate has no lesions.

          C: Femoral head with separated articular cartilage, and the growth plate has lesions.

          D: Femoral head with separated articular cartilage. The very severe form where the femoral head is lost is disintegrated very much or the femoral head is retained within the acetabulum.
