ABSTRACT
0.05). Incision size,operating time,blood loss,hospital stay,medical device expenses,postoperative VAS and ODI,clinical outcomes,fusion rates,and complication rates were studied and tested with independent sample t test and x2 test.[Results]The mean follow-up was 19.1 months (range,12~25 months) in group A and 24.6 months (range,9~36 months) in group B.There were statistically significant differences in the incision size,operating time,blood loss,hospital stay and medical device expenses (P0.05).[Conclusion]Unilateral transforaminal lumbar interbody fusion with unilateral pedicle screw fixation has the advantages of small incision,little bleeding,no destruction of the contralateral structure,short operating time or hospital stay,low medical device expenses and good recovery.But the operation indications must be strictly defined.
