Objective:To explore the effects of the treatment by internal fixation operation through pedicle of vertebral arch for thoracolumbar vertebral fracture cases.Methods:48 cases sufering from thoracic or lumbar vertebral fracture accept the treatment by internal fixation operation through pedicle of vertebral arch and intervertebral body fusion.Total or partly resection of vertebral plate was performed while needed for decompression.The lasted 18～30 months or more.Results:All the injured vertebrae had get reposition of height and the Cobb angle get well without any serious complication.Follow-up shows that every patient has get solid fusion with good height and stability

and the Cobb angle stain well.Thirty-six of the 38 spinal injury patients have get Franke1 grade raise in different degree.There were 2 Franke1A grade spinal injury cases with no neuro-function amelioration

who both got late hospital admission.Conclusion:For thoracolumbar vertebral fracture

internal fixation operation through pedicle of vertebral arch and intervertebral body fusion provide reposition of the injured vertebra height and spinal stabilization

and the spinal nerves function will get improved

and the operation indication and opportunity must be assurance.
