ABSTRACT
Objective To study the effect of short course of mini dose hormonal application after long-segment spinal fusion using allograft bone in scoliosis.Methods A retrospective study was made in 106 patients with scoliosis,who underwent posterior spinal fusion during May,2004 to Jan,2007 in our hospital.These patients were divided into two groups.Hormone group,68 cases,were 13 to 28 years old with a mean age of 16.5 years old.The average fused segments were 9.0 vertebrae(range from 7 to 12 vertebra).Glucocorticoid was used after operation about 5 to7 days.No hormone group,38 eases,were 14 to 30 years old with a mean age of 17.5 years old.The average fused segments also were 9.0 vertebrae(range from 6 to 12 vertebra).No glucocorticoid was used after operation.All patients received spinal instrumentation with TSRH system and spinal fusion with allograft bone.The temperature,white blood cell(WBC),ESR,drainage and complications between two groups after operation were comparative analyzed.Result Between two groups,the variance of the figures of the temperature,WBC,ESR and drainage are statistically significant.There was less complication in hormone group than that in no hormone group.Conclusion After the operation of the segments spinal fusion by allograft bone,using mini-close glucocorticoid by short course of treatment can significantly decrase some complications and ensure spinal fusion.
