Perthes disease | Radiology Reference Article |
Osteonecrosis generally occurs secondary to abnormal or damaged blood supply to the femoral epiphysis, leading to fragmentation, bone loss, and eventual structural collapse of the femoral head. You can also scroll through stacks with your mouse wheel or the keyboard arrow keys. Bracing may be used in milder cases, although enfernedad neck and acetabular osteotomies may be required to correct more severe abnormal femoroacetabular malalignment. Case 4 Case 4.
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. The radiographic findings are those of osteonecrosis.
It should not be confused with Perthes lesion of the shoulder. In a small number of patients with Perthes, the radiograph will be normal and persistent symptoms will trigger further imaging, e.
The typical findings of advanced burnt out stage 4 Perthes disease are:. Case 16 Case Case 5 Case 5.
Slipped upper femoral epiphysis Slipped upper femoral epiphysis. There is a separate system for staging of Perthes disease see Catterall classification.
Treatment in Perthes disease is largely related to symptom control, particularly in the early phase of the disease. Case 18 Case It is important to be certain that there is no other cause of osteonecrosis e. Thank you for updating your details. Cases and figures Imaging differential diagnosis. The investigation of atraumatic limp will often include a hip ultrasound to look for effusion, but ultrasound is unlikely to pick up osteonecrosis.
Traditionally arthrography performed under general anesthesia with conventional fluoroscopy is performed to assess congruency between the femoral head and the acetabulum in a variety of positions 3. Synonyms or Alternate Spellings: The aim of therapy is to try and maintain good femoroacetabular contact and a round femoral head. The presence of metaphyseal involvement not only increases the likelihood of femoral neck deformity but also make early physeal closure with resulting leg length disparity more likely.
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. As changes progress, the width of the femoral neck increases coxa magna in order to increase weight-bearing support.

Case 7 Case 7. Edit article Share article View revision history. Case 13 Case 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. Some children have a coincidental history of trauma. MRI is increasingly replacing this, in an effort to eliminate pelvic irradiation. Case 6 Case 6. Developmental dysplasia of hip Developmental dysplasia of hip.
Blood tests are typically nips in Perthes. Epidemiology Clinical presentation Pathology Radiographic features Treatment and prognosis History and etymology Differential diagnosis References Images: Case 11 Case As the disease progresses, fragmentation and destruction of niks femoral head occurs. Perthes disease is relatively uncommon and in Western enfemredad has an incidence approaching 5 to The best initial test for the diagnosis of Perthes is a pelvic radiograph.

Case 20 Case Check for errors and try again. Most children present with atraumatic hip pain or limp 3,5,6.
