Lumbar fusion research comparing the effect of unilateral and bilateral internal fixation for lumbar disc herniation / 中国医学装备

ABSTRACT

Objective:To compare lumbar fusion effect of unilateral and bilateral internal fixation for lumbar disc herniation, to explore more effective, reliable treatment. Methods:112 cases of lumbar selects my courtyard 2007 April-2010 year in April admitted to the disc herniation were randomly grouped, unilateral group and bilateral group with 56 cases in each group, respectively, to take unilateral or bilateral internal fixation for the treatment of lumbar fusion operation, compared two groups of patients and the therapy effect. Results:the unilateral group operation time, amount of bleeding during the operation and hospitalization expenses below the bilateral group, there was significant difference(t=8.857, t=9.620, t=12.338;P0.05);the two group patients after VAS and ODI were significantly decreased (P0.05);the unilateral group at the end of the follow-up of 50 cases of intervertebral fusion, the fusion rate was 96.2%, the bilateral group interbody fusion in 52 cases, the fusion rate was 100%, two groups of patients at the end of the follow-up intervertebral fusion rate has no obvious statistical difference (x2=0.372, P<0.05);unilateral group were no significant complications, bilateral group were found 1 cases of intervertebral fusion device implant bone absorption, 1 cases highlight the root symptoms, complication rate was 3.8%, the two groups of patients with complications were no significant statistical difference. Conclusion:Lumbar unilateral and bilateral internal fixation can effectively improve the patients with lumbar disc herniation pain symptoms, and has good fusion degree, high security, and unilateral internal fixation operation time is shorter, less blood loss and the burden of patients is smaller, need operation treatment for severe lumbar disc herniation, fusion and unilateral internal fixation for the treatment of recommend the use of lumbar.
