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. Articles Cases Courses Quiz. Support Radiopaedia and see fewer ads. The younger the age at the time of presentation, the more benign disease course is expected and also for same age, the prognosis is better in boys than girls due to less maturity 5,8.
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. In a small number of patients with Perthes, enfeemedad radiograph will be normal and persistent symptoms will trigger further imaging, e.
As changes progress, the width of the femoral neck increases coxa magna in order to increase weight-bearing support.
Unable to process the form. Developmental dysplasia of hip Developmental dysplasia of hip. Dn is typically at a younger age than slipped nio femoral epiphysis with peak presentation at years, but confidence intervals are as wide as years 8. Case 2 Case 2. The investigation of atraumatic limp will often include a hip ultrasound to look for effusion, but ultrasound is unlikely to pick up osteonecrosis. Case 18 Case perrthes Case 17 Case Log in Sign up. Case 4 Case 4. Some children have a coincidental history of trauma.
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.
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:. Check for errors and try again. 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.

Case 16 Case Additionally, tongues of cartilage sometimes extend inferolaterally into the femoral neck, creating lucencies, which must be distinguished from infection or neoplastic lesions 4.
Case 6 Case 6. This may precipitate the presentation or the realisation of symptoms that in fact had been long standing.
Meyer dysplasia Meyer dysplasia. Case 19 Case Treatment in Perthes disease is largely related to symptom control, particularly in the early phase of the disease. Case 9 Case 9. 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. In this situation, operative management is sometimes required to either ensure appropriate coverage of the femoral head by the acetabulum, or to replace the femoral head in adult life.
The radiographic findings are those of osteonecrosis.
