Abstract:

BACKGROUND: Whether thoracic or lumbar vertebral burst fracture with intact posterior longitudinal ligament complex needs decompression and which reduction effect of adopted methods is reliable, now there is little controlled clinical  studies.
OBJECTIVE: To investigate and discuss the clinical effect of posterior open-reduction and indirect-decompression technique (POIT) in the treatment of thoracic or lumbar vertebral burst fracture caused by posterior column stretch injury with intact posterior longitudinal ligament complex, and to analyze the two operation methods: POIT and posterior open-reduction and direct vision decompression technique (PODT).
METHODS: Totally 48 cases with thoracic or lumbar vertebral burst fracture caused by posterior column stretch injury with intact posterior longitudinal ligament complex were divided into two groups randomly. Twenty-three cases were treated with POIT and twenty-five cases were treated with PODT. Complications rate, kyphosis correction, vertebral tube occupying place and recovery of nerve injury were observed.
RESULTS AND CONCLUSION: The patients were all followed up from 20 to 25 months. The incidence of early complications, long-term residual back pain and incidence of activity limitation in the POIT group were lower than those in the PODT group. One week after fixation, anterior and posterior heights of vertebral body and Cobb angle correction in the POIT group were higher than those in the PODT group. There was no statistical difference of the recovery of nerve injury and the loss of reduction in the two groups after 1 year postoperation. It is indicated that using POIT technique to treat the thoracic or lumbar vertebral burst fracture caused by posterior column stretch injury with intact posterior longitudinal ligament complex is an appropriate technique, and the outcomes of the POIT operation is better than the PODT operation.
