Unilateral biportal endoscopic posterior cervical foraminotomy for cervical radiculopathy
Objective To investigate the clinical efficacy of posterior unilateral biportal endoscopic(UBE)cervical dis-cectomy for cervical radiculopathy under general anesthesia.Methods A retrospective analysis of 35 patients with cervical disc herniation uderwent posterior UBE cervical discectomy under general anesthesia from March 2021 to March 2023 was per-formed,including 17 males and 18 females,with an average age of(56.00±7.79)years old ranging from 42 to 69 years old.The non-operative treatment time was 6 to 27 weeks with an average of(16.03±4.56)weeks.MRI showed lateral cervical disc her-niation in 19 cases and foraminal cervical disc herniation in 8 cases.The pathological segments distribution was as followsL45 in 5 cases,C5,6 in 12 cases C6.7 in 18 cases.CT/MRI was performed 1 to 3 d after surgery to evaluate the decompression,and the visual analogue scale(VAS),the Japanese Orthopedic Association(JOA)score,the stability of cervical spine surgery seg-ment and the change of intervertebral height were recorded.Results All 35 patients successfully completed the operation,and the operation time was(55.88±5.02)min,the hospital stay after surgery(3.53±0.74)d.All 35 patients were followed up from 12 to 24 months with an average of(14.53±2.32)months.The VAS of preoperative,postoperative 1 day and 12 months were(7.000±0.875),(2.540±0.611),(2.143±0.772),respectively,the VAS at each time point before and after surgery were statis-tically significant(P＜0.05).The JOA scores of preoperative,postoperative 1 day and 12 months were(11.660±0.533),(16.430±0.655),(16.540±0.611),respectively.The intervertebral height of the lesion segment at preoperative and 12 months was(6.206±0.493)mm and(6.147±0.497)mmm,respectively,and the difference was not statistically significant(P＞0.05).None of the patients had cervical spine segment instability before or after surgery.According to the modified Macnab criteria,the clinical efficacy was evaluated at 12 months after operation,32 cases were excellent,2 cases were good,and 1 case was good.Conclusion UBE cervical discectomy is a minimally invasive,safe and effective surgical method for the treatment of sin-gle-segment cervical disc herniation,which may be an alternative to the treatment of cervical foraminal herniation,but due to the small sample size and short follow-up time,its long-term efficacy needs to be further observed.
