Diagnosis and treatment of multiple level lumbar disci herniation by means of magnetic resonance imaging

Objective:To evaluate the efficacy of the MRI in the diagnosis and treatment of the patient with multiple level lumbar disci herniation.Method:98 cases with multiple level lumbar disci herniation were performed dynamic MRI(neutral or flexsion ).Based on level,degeneration or clinical manifestation and MRI,83 cases underwent surgical operation。Result:In these cases double level group at L4/5 associated with L5/S1,and L3/4 with L4/5 was most commanly seen.There were 43 cases(43%) and 21 cases(21%) respectively,L3/4 with L5/S1 were 6 cases(6 1%),3 multiple level herniation was 19 cases(20%),and other 9 cases(9%)had 4 or 5 level disc herniation.83 cases who accepted surgical operation were followed up 6～36 months with average 1.5 years.The excellent and good effective rate was 93 9%.Conclusion:The sensitivity of MRI for diagnosing disc herniation is higher than other methods.It is possible to classify and localize multiple level lumbar disci herniation which of the main lession leads to symptoms and signs by means of dynamic MRI.Thus,it will provide fundation for treatment.
