Aim:
To evaluate and compare clinical outcomes between the posterior short-segment pedicle fixation with injured vertebra fixation (PSPFI) and fixation without injured vertebra fixation (PSPF) for thoracolumbar burst fracture (TLBF).
Material And Methods:
In this retrospective study, a total of 78 patients with TLBF were included and assigned to PSPFI (n=46) and PSPF (n=32) groups. The operative time, blood loss, perioperative complications, Oswestry disability index (ODI), and visual analog pain score (VAS) were examined immediately after surgery, 1 month, 3 months, and 1 year after surgery. Moreover, the postoperative vertebral height correction rate and postoperative Cobb angle correction rate were examined immediately and 1 year after surgery, as well as the corrected vertebral height loss rate and Cobb angle correction loss rate.
Results:
No significant difference was identified in terms of operative time, blood loss, perioperative complications, ODI, and VAS after surgery (p > 0.05) between the PSPFI and PSPF groups. Moreover, the postoperative vertebral height correction rate and postoperative Cobb angle correction rate showed no difference between the groups as well. However, the PSPFI group had a significantly lower loss rate in terms of corrected vertebral height loss rate and Cobb angle correction loss rate than the PSPF group 1 year after surgery (p < 0.05).
Conclusion:
PSPFI and PSPF achieve similar clinical outcomes. However, posterior short-segment pedicle fixation with injured vertebra significantly maintains vertebral height correction rate and Cobb angle correction rate, which serve as a better choice for the treatment of TLBF.
