The Curative Effect Analysis Of Unilateral Pedicle Internal Fixation Of Single Cage Insertion And Bilateral Pedicle Fixation For Lumbar Intervertebral Discherniation

Objective: To have a comparative analysis and evaluation upon the differences between unilateral pedicle internal fixation of inclined single cage insertion and bilateral pedicle fixation therapy for LDH.Methods: 60 patients with lumbar disc herniation after internal fixation surgery received and cured in this hospital from January 2001 to August 2013 were divided into two different groups: 32 cases received unilateral pedicle internal fixation of single cage insertion as unilateral fixation group(group A), and 28 cases received bilateral pedicle internal fixation of interbody spinal fusion as bilateral fixation group(group B).Comparison was made upon the operation time, blood loss, hospitalization time,postoperative morbidity rate, fusion rate and the VAS score.Results: the comparison difference upon the operation time, blood loss, and hospitalization time between the unilateral fixation group and the bilateral fixation group have statistical significance(P < 0.05). All the patients were followed-up 12-26 months after the surgery, and the average mean is 18.5 months. The statistic differences upon postoperative morbidity rate and fusion rate between the two groups have no statistical significance(P > 0.05). The difference between the VAS score of the final follow-up and the preoperative score of the same group has statistical significance(P <0.05), while the difference between the two groups show no statistical significance(P >0.05).Conclusion: the unilateral pedicle internal fixation of single cage insertion therapy shows no obvious difference with the bilateral pedicle internal fixation therapy on curative effect, while it has low blood loss, less damage upon spine structure, and short operation time as well as hospitalization time and so on.
