Research advances on using pMRI for predicting avascular necrosis after closed reduction in developmental dislocation of the hip

- Abstract:
- Developmental dislocation of the hip (DDH) is one of the most common congenital deformities of the lower limbs in children.Currently,closed reduction under general anesthesia followed by spica cast fixation is the first-line treatment for DDH in children aged 6 to 24 months.However,avascular necrosis (AVN) of the femoral head remains a major complication following closed reduction.There is a growing evidence that gadolinium-enhanced perfusion magnetic resonance imaging (pMRI) after closed reduction can provide valuable data regarding femoral head blood perfusion and signal alterations.Early detection of ischemia during reduction may allow for prediction of AVN development,which could form the basis for further modifications to current treatment protocols or the development of new therapeutic approaches.This review summarizes recent advances in the use of pMRI for predicting AVN following closed reduction of DDH.
