Clinical observation of short-term efficacy of fenestration discectomy combined suturing the annulus for lumbar disc herniation

Objectives: To explore feasibility and short-term efficacy of suturing the annulus after discectomy for lumbar disc herniation. Methods: : 229 cases operated with mono-segment discectomy were analyzed from June 2021 to December 2021,among them,133 cases operated with fenestration discectomy combined suturing the annulus and 96 cases operated with fenestration discectomy.The length of surgical incision,the operating time,blood loss,the average temperature for three days after surgery,duration of hospitalization after operation,preoperative and postoperative JOA score,visual analogue scale, MRI and DTI images were compared. Results: : No significant difference was found between the two groups in the length of surgical incision,the operating time,blood loss,the average temperature for three days after surgery,duration ofhospitalization after operation.But significant differences could be observed in postoperative JOA score,VAS score,the same with preoperative and postoperative score in the same group,get a good rate of improvement surgery.Postoperative DTI images of sutured group is better than the control group. Conclusion: The symptoms of the lumbardisc herniation can be reliefed effectively by both methods,no significant difference could be found between them in the operating time,blood loss,etc.But after suturing,the ruptured annulus can instantly get the mechanical integrity,so that the nucleus is not easy to prolapse through the damaged annulus,and can reduce the rate of recurrent lumbar disc herniation. Furthermore,the function and stability of the spine in sutured patients can be reserved,owing to the more healthy nucleus pulposus has been kept.But the long-term efficacy of suturing the annulus still needs further follow-up.
