Short segment fixation in combination of pedicle screw in injured vertebrae for thoracolumbar fractures / 局解手术学杂志

ABSTRACT

Objective To assess the clinical outcome of short segment fixation in combination of pedicle screw in injured vertebrae for thoracolumbar fractures. Methods Twenty-one cases of thoracolumbar fractures received short segment fixation combined with pedicle screw in injured vertebrae surgery. The protruding after angle correction and vertebral body height recovery situation were measured by X-ray film before and after surgery. Results All the patients were followed up for 6~20 months,achieved good reduction effect. The imaging measure-ment results found that before the operation Cobb’s angle was (26. 4 ± 7. 3),fracture fanterior flange height was (56. 1 ± 12. 5)%. Com-pared with after the operation and the end of follow-up of Cobb’ s and fracture fanterior flange height,the difference had statistical significance (P0. 05). Conclusion Short segment fixation in combination of pedicle screw in injured vertebrae can restore the height of vetebra,rectify protrusion deformity,which is an effective method for thoracolumbar fracture.
