Prognosis is also influenced by the percentage of femoral head involvement and degree of primary deformity of the femoral head and the secondary osteoarthritic changes that ensue. Eventually, the femoral head begins to fragment stage 2with subchondral lucency crescent sign and redistribution of weight-bearing stresses leading to thickening of some trabeculae which become more prominent.
Blood tests are typically normal in Perthes. Synonyms or Alternate Spellings: Developmental dysplasia of hip Developmental dysplasia of hip. Case 17 Case Presentation is typically at a younger age than slipped upper femoral epiphysis with peak presentation at years, but confidence intervals are as wide as years 8.
There is a separate system for staging of Perthes disease see Catterall classification. This may precipitate the presentation or the realisation of symptoms that in fact had been long standing.

Case 10 Case Additionally, tongues of cartilage sometimes extend inferolaterally dr the femoral neck, creating lucencies, which must be distinguished from infection or neoplastic lesions 4. Case 9 Case 9. Case 7 Case 7. Case 19 Case Cases and figures Imaging differential diagnosis. In a small number of patients with Perthes, the radiograph will be normal and persistent symptoms will trigger further imaging, e.
The investigation of atraumatic limp will often include a hip ultrasound to look for effusion, but ultrasound is unlikely to pick up osteonecrosis.
Case 6 Case 6. In this enfermesad, operative management is sometimes required perrthes either ensure appropriate coverage of the femoral head by the acetabulum, or to replace the femoral head in adult life.
Slipped upper femoral epiphysis Slipped upper femoral epiphysis.

Case 16 Case Check for errors and try again. As changes progress, the width of the femoral neck increases coxa magna in order to increase weight-bearing support. Case 18 Case Case 2 Case 2. Support Radiopaedia and see fewer ads.
Case 4 Case 4. Osteonecrosis generally occurs secondary to abnormal or damaged blood supply to the femoral epiphysis, leading to fragmentation, bone loss, and eventual enfermwdad collapse of the femoral head.

Treatment in Perthes disease is largely related to symptom control, particularly in the early phase of the disease.
MRI is increasingly replacing this, in an effort to eliminate pelvic irradiation. Some children have a coincidental history of trauma. As the disease progresses, fragmentation and destruction of the femoral head occurs.
About Blog Go enfermeead. The radiographic changes to the femoral epiphyses depend on the severity of osteonecrosis and the amount of time that there has been alteration of blood supply:. Bracing may be used in milder cases, although femoral neck and acetabular osteotomies may be required to correct more severe abnormal femoroacetabular malalignment.
Case 5 Case 5.
It is important to be certain that there is no other cause of osteonecrosis e. Articles Cases Courses Quiz.
