Percutaneous full-endoscopic discectomy for foraminal L_V–S_I herniation with cranial migration by interlaminar contralateral approach

OBJECTIVE: The evaluation of the clinical results and technical features of the Percutaneous full-endoscopic discectomy for foraminal LV–SI herniation with cranial migration by interlaminar contralateral approach.

MATERIAL AND METHODS: Analyzed the results of percutaneous full-endoscopic discectomy for foraminal LV–SI herniation with cranial migration by interlaminar contralateral approach performed of 6 patients for the period 2016–2019. To evaluate the results of surgical treatment used the ODI questionnaire, VAS scale and McNab. The assessment was made before surgery, the next day, after 1, 6 12 and 24 months after surgery.

RESULTS: The average severity of preoperative radicular leg pain for VAS after surgery decreased from 7.6±1.1 to 1.2±0.8. The average ODI improved from 66.2±5.4 до 19.2±2.8 after 1 month; up to 14.2±2.2 after 6 months; to 15.2±2.2 after 12 months and to 15.2±2.2 after 24 months after surgery, respectively According to the McNab scale, all patients rated the treatment results “excellent” and “good”.

CONCLUSION: Percutaneous full-endoscopic discectomy for foraminal LV–SI herniation with cranial migration by interlaminar contralateral approach is a safe and effective method; provides the most optimal trajectory of endoscopic approach; facilitates early postoperative activation and recovery of the patient.
