Case 5 Case 5. Engermedad Clinical presentation Pathology Radiographic features Treatment and prognosis History and etymology Differential diagnosis References Images: Case 7 Case 7.
Case 16 Case 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:.
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. The presence of metaphyseal involvement not only increases the likelihood of femoral neck ce but also make early physeal closure with resulting leg length disparity more likely.
Case 20 Case 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. It should not be confused with Perthes lesion of the shoulder. Thank you for updating your details.
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 13 Case Additionally, tongues of cartilage sometimes extend inferolaterally into the femoral neck, creating lucencies, which must be distinguished from infection or neoplastic lesions 4. The typical findings of advanced burnt out stage 4 Perthes disease are:.
Case 9 Case 9. Loading Stack – 0 images remaining. MRI is increasingly replacing this, in an effort to eliminate pelvic irradiation. The radiographic findings are those of osteonecrosis.

Case 3 Case 3. 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. Case 6 Case 6.
Check for errors and try again. Case 4 Case 4. Case 2 Case 2. There is a separate system for staging of Perthes disease see Catterall classification. 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 a small number of patients with Perthes, the radiograph will be normal and persistent symptoms will trigger further imaging, e. Support Radiopaedia and see fewer ads.

This may precipitate the presentation or the realisation of symptoms that in fact had been long standing. As changes progress, the width of the femoral neck increases coxa magna in order to increase weight-bearing support. The aim of therapy is to try and maintain good femoroacetabular contact and a round femoral head.
Perthes disease is relatively uncommon and in Western populations has an incidence approaching 5 to It is important to be perthew that there is no other cause of osteonecrosis e. The best initial test for the diagnosis of Perthes is a pelvic radiograph.
Articles Cases Courses Quiz. Case 18 Case enfefmedad In this situation, operative management is sometimes required to either ensure appropriate coverage of enfermecad femoral head by the acetabulum, or to replace the femoral head in adult life.
Case 12 Case Boys are five times more likely to be affected than girls.
