| 摘 要： | According to literatures, ischemia of the femoral head epiphysis is one of the most common complications dur- ing closed or open reductions of the hip performed for treating hip joint dysplasia1]. Once ischemia of the femoral head epiphysis took place, the epiphyseal cartilage, growth plate cartilage and secondary ossification center would be affected, and the cartilage or bone in femoral head epiphysis may suffer from necrosis, which could be followed by growth arrest and deformity of the sec…

| Abstract: | The purpose of this study is to demonstrate if Gadolinium-enhanced MRI can detect early reversible ischemia of the femoral head epiphysis caused by hip hyper-abduction in piglets. Between 3 and 6 h consistent hyper-abduction, gadolinium-enhanced MRI was performed in 20 femoral heads of 10 piglets. After completion of MRI scan, the piglets were allowed to ambulate freely for 1 or 7 days and re-imaged. The enhanced-MRI results of epiphyseal and physeal cartilage and the secondary center of ossification were observed. MRI appearances and histological findings were compared. On Gadolinium-enhanced MRI, decreased or absent enhancement was seen in 14 cartilaginous epiphyses of all 20 femoral heads. Reperfusion was completed in 10 of 14 femoral heads after one day of am- bulation and in the rest 4 after 7 days of ambulation. Gadolinium-enhanced MRI can identify early ischemia and its reversal of the capital femoral epiphysis induced by hip hyper-abduction. |
