Objective:
To investigate the effectiveness of minimal invasive neurosurgery in treatment of intervertebral foraminal lesions.
Method:
Fifty-six patients with intervertebral foraminal lesions were divided into 2 groups: minimal invasive neurosurgery group (MG group, n=31) and traditional neurosurgery group (TG group, n=25). Their pre-operational clinical conditions, methods of surgery, duration and effectiveness of operation were analyzed retrospectively. Follow-up was conducted for 3-48 months.
Results:
Twenty-three of the 25 patients in the TG group (92%) had their lesions resected completely and 2 of the 31 patients (8%) underwent subtotal resection. In the MG group 28 of the 31 patients (90.32%) had their lesions resected completely, 2 (6.45%) underwent subtotal resection, and 1 patient (3.23%) showed epidural remains and did not receive further treatment. There was no significant difference in the effective rate between these 2 groups. The operation time of the TG group was (188 +/- 35) minutes, significantly longer than that of the MG group [(140 +/- 26) minutes, P < 0.01]. Follow-up showed that all patients resumed their normal life except the patient with epidural remains in the MG group, and no recurrent patient was found.
Conclusion:
The minimal invasive neurosurgery is convenient, effective, and cheaper to treat intervertebral foraminal lesions. However, precise localization and intimate knowledge of the anatomy are important.
