| Abstract: |
group of severe forms of the disease.The treatment of a patient with PFFD has some general guide lines to be used, according to the amount of discrepancy at the age of maturity adequacy of proximal musculature, femoral rotation, proximal joint stability, the presence or absence of the head and the condition of the acetabulum. Treatment varies from no intervention (for 0-2 cm of discrepancy), the use of a shoe lift, epiphysiodesis, leg shortening (for 2-6 cm of discrepancy), limb lengthening (for 6-20 cm of discrepancy) and amputation and prosthetic fitting (for more than 20 cm of discrepancy).The associated anomalies with PFFD should be treated before attempting to treat PFFD. These anomalies are: coax vara, acetabular dysplasia, patellar or tibial dislocation, external rotation deformity of the hip, distal femoral valgus deformity, soft tissue contractures and knee instability.So, with the recent advances in limb lengthening, particularly by using the Ilizarov fixator, lengthening and reconstruction in PFFD has become more successful and minimizes the need for the depressive and humiliating technique of limb amputation, which is restricted to a specific.
