Legg-Calve-Perthes Disease: Multimedia
Updated: May 28, 2008
Multimedia
 | Media file 1: Legg-Calvé-Perthes disease. Stage II disease. Note the slight widening of the left hip joint, representing a small joint effusion (see also Image 2 in Multimedia). Joint widening can also be secondary to hypertrophy of the cartilage. |
 | Media file 2: Legg-Calvé-Perthes disease. Stage II disease. Note the slight widening of the left hip joint representing a small joint effusion (see also Image 1 in Multimedia). Joint widening can also be secondary to hypertrophy of the cartilage. |
 | Media file 3: Legg-Calvé-Perthes disease. The left joint effusion is apparent. The femoral head is smaller on the left than the right (see also Image 4 in Multimedia). The femoral head is also considerably denser on the left side. Joint widening can also be secondary to hypertrophy of the cartilage. |
 | Media file 4: Legg-Calvé-Perthes disease. The left joint effusion is apparent. The femoral head is smaller on the left than the right (see also Image 3 in Multimedia). The femoral head is also considerably denser on the left side. Joint widening can also be secondary to hypertrophy of the cartilage. |
 | Media file 5: Legg-Calvé-Perthes disease. Image shows subchondral sclerosis and radiolucency in the left femoral head (stage II disease). The femoral head is slightly smaller on the left than the right (see also Image 6 in Multimedia). |
 | Media file 6: Legg-Calvé-Perthes disease. The left subchondral radiolucency is more readily demonstrated on a frog-leg view and represents subchondral fracture (see also Image 5 in Multimedia). |
 | Media file 7: Legg-Calvé-Perthes disease. Image shows left femoral subchondral sclerosis and radiolucency (see also Image 8 in Multimedia). |
 | Media file 8: Legg-Calvé-Perthes disease. Image shows left femoral subchondral sclerosis and radiolucency (see also Image 7 in Multimedia). |
 | Media file 9: Legg-Calvé-Perthes disease. Image shows flattening and early fragmentation of the left femoral head with the presence of femoral neck cysts. The femoral head is obviously smaller on the left than on the right (see also Image 10 in Multimedia). |
 | Media file 10: Legg-Calvé-Perthes disease. Image shows flattening and early fragmentation of the left femoral head with the presence of femoral neck cysts. The femoral head is obviously smaller on the left than on the right (see also Image 9 in Multimedia). |
 | Media file 11: Legg-Calvé-Perthes disease. Image shows flattening and early fragmentation of the left femoral head with the presence of femoral neck cysts. The femoral head is obviously smaller on the left than on the right. |
 | Media file 12: Legg-Calvé-Perthes disease. Image shows fragmentation of the left femoral head. Also note widening and shortening of the left femoral neck. |
 | Media file 13: Legg-Calvé-Perthes disease. Image shows loss of structural integrity of the right femoral head. Also note lateral extrusion of the right femoral head. |
 | Media file 14: Legg-Calvé-Perthes disease. Image shows loss of structural integrity of the left femoral head. Also note the widening and shortening of the femoral neck, and more importantly, the severe subluxation. |
 | Media file 15: Legg-Calvé-Perthes disease. Plain radiograph in an adult patient with residual coxa magna and plana deformity with superimposed joint changes (compare with the CT scans in Images 16-18 in Multimedia). |
 | Media file 16: Legg-Calvé-Perthes disease. Axial nonenhanced CT scan through the hip joints in the same patient as in Image 15 in Multimedia more clearly shows the loss of structural integrity of the right femoral head. |
 | Media file 17: Legg-Calvé-Perthes disease. Nonenhanced axial CT section through the hip joints obtained at a different level in the same patient as in Image 15 in Multimedia. Once again, the scan shows the loss of structural integrity of the right femoral head. Note the acetabular subchondral sclerosis. |
 | Media file 18: Legg-Calvé-Perthes disease. Coronal reconstruction shows flattening, sclerosis, and early fragmentation of the right femoral head (same patient as in Images 15-17 in Multimedia). |
 | Media file 19: Legg-Calvé-Perthes disease. Coronal T2-weighted MRIs show irregularity and flattening of cortical margins of the left femoral epiphysis. Also note a mild joint effusion and subluxation and hinge deformity of the left femoral head. |
 | Media file 20: Legg-Calvé-Perthes disease. Coronal T1-weighted MRIs show the loss of normal high signal intensity in the left femoral epiphysis, which now has low signal intensity. |
 | Media file 21: Legg-Calvé-Perthes disease. Axial T1-weighted MRIs through the femoral heads show low signal intensity in the left femoral head. |
 | Media file 22: Legg-Calvé-Perthes disease. Technetium-99m diphosphonate bone scan shows a photon-deficient defect in the right femoral head. |
 | Media file 23: Legg-Calvé-Perthes disease. Zoomed images of the same patient as in Image 22 in Multimedia show the photopenic defect more clearly. |
 | Media file 24: Legg-Calvé-Perthes disease. Radiograph obtained at the same time as the radionuclide scans in Images 22-23 in Multimedia illustrates the usefulness of isotope bone scans. The radiographic changes of subchondral lucency are subtle. |
 | Media file 25: Legg-Calvé-Perthes disease. Coronal T2-weighted MRI shows irregularity and flattening of cortical margins of the right femoral epiphysis and the loss of normal signal intensity. Also, note a mild effusion in the joint (same patient as in Images 22-24 in Multimedia). |
