ABSTRACT
[Objective] To discuss the opportunity and method of the posterior route operation in the upper-middle thoracic fracture to resume the thoracic vertebral normal sequence、decompression completely and reconstruction immediate stability as soon as possible,so as to relieve pressure to spinal cord and nerve and avoid the secondary trauma of spinal cord and nerve and blood vessel and patients can do rehabilitation.[Method]Seventeen cases of the patients with upper-middle thoracic vertebral fracture were operated on with posterior route early decompression、fusion、internal fixation under general anaesthesia.There were 17 cases including male 11 and female 6 with the ages from 18 to 53 years(average 33.8 years).The injury reason: 7 cases as traffic accident,10 cases as falling from high altitude.The time from trauma to hospital were 1 hr.to 72 hrs.(average 15.4 hrs.).The injured segment of vertebral: T5～T10 segment,T5 2 cases,T6 6 cases,T7 5 cases,T9 4 cases,T10 2 cases.The function evaluation of spinal cord: 10 cases with incompletely neurological defect,7 cases with completely neurological defect.[Result]All patients were followed for 6~27 months(average 13.5months).The thoracic vertebra restoration were contentment and bone fuse were obtained in 12 weeks after operation.10 cases with incompletely neurological defect got improved postoperatively and 5 cases activity normolly.7 cases with completely neurological defect got improved of numbness and pain.[Conclusion]The upper-middle thoracic vertebral fracture can be operated early and the outcome are contentment.
