Fulcrum-Bending Radiograph And Operationt Strategy Of Scoliosis Associated With Chiari Malformation And/Or Syringomyelia

Objective: To evaluate the help of fulcrum-bending radiograph and new treatment strategy to the scoliosis with Chiari malformation and/or syringomyelia,and analyze the effect of operation.Methods: 18 cases suffered from scoliosis with Chiari malformation and/or syringomyelia were divided into 2 groups for surgical treatment: (1) Group 1: 6 cases had scoliosis with Chiari malformation and/or syringomyelia without obvious neurological impairment, their scoliosis was corrected with anteroposterior instrumentation afer Halo's traction of one week.(2)Group 2: another 6 patients having similar scoliosis underwent posterior orthopedic operation according to the result of preoperative suboccipital fulcrum-bending radiograph.Results: In 6 patients who underwent opration after traction, the average frontal correction was 61%.In another 6 cases with only posterior operation, the average frontal correction was 52%,and the result of opration is correspond to the fulcrum-bending radiograph's.Conclusion: Patients had scoliosis with Chiari malformation and/or syringomyelia without obvious neurological impairment can be operated on the basis of fulcrum-bending radiograph without preoperative traction,and the therapeutic effect was similar to classic operation's result.
