Abstract:
[Objective]To study the methods and clinical results of infrared fluoroscopic navigation guiding system guided operations for the treatment of thoracolumbar fracture and analysis the common problems in the treatment of thoracolumbar fracture.[Method]A retrospective analysis was carried out in 56 cases with thoracolumbar fracture and dislocation from March 2003 to December 2006.There were 36 males and 20 females,ranging from 18-56 years(average 35 years).Segments involved:T11 10 cases,T12 13 cases,L1 21 cases,L29 cases,L3 3 cases.According to the classification of AO:there were 26 cases of type A,17 cases of type B,13 cases of type C.According to the classification of ASIA:there were 11 cases of type A,18 cases of type B,13 cases of type C,8 cases of type D,6 cases of type E,among which 35 cases had neurological disfunction symptom.Operation were performed under the suspection of computer assisted navigation system,32 cases underwent posterior decompession approach,withAF transpedicular screw internal fixation in thoracolumbar spine.Fifteen cases underwent anterior approach spondylectomy with bone graft and plate internal fixation.Other cases underwent conservative treatment.The vertebral stabilization and the struction of the three columns were reconstructed.[Result]The mean operati on time was 200 min,ranging from 160 to 300 min.The mean blood loss during operation was 1 000 ml ranging from 800 to 2 000 ml.All patients were followed up for 6 to 36 months(10 months on average).Neurological status improved to A ASIA grade in 4 cases,B grade 5 cases,C grade 11 cases,D grade 14 cases,E grade 22 cases.[Conclusion]The patient had remarkable improvement in clinical relief.In order to achive the best effect in the treatment of thoracolumbar fracture,correct treatments of primary trauma and injury type and appropriate management are necessary for the treatment of thoracolumbar fracture.Also,computer assisted navigation system enhances accuracy and further improves the safety of spine surgery.
