Abstract

Lumbar discectomy has successful initial clinical outcome; its long-term success rate decreases to 40–80% due to chronic low back pain and recurrent disc herniation. To evaluate the clinical results of Posterior Lumbar Interbody Fusion with a single unilateral stand-alone PEEK (Poly-Ether-Ether-Ketone) cage without pedicle screw fixation for single level lumbar disc herniation. A retrospective study of 40 patients (24 men and 16 women) with lumbar disc herniation, was conducted in the period from January 2016 through January 2021. The follow-up continued till December 2021. All patients suffered from single level lumbar disc herniation and were treated with Posterior Lumbar Interbody Fusion with a single unilateral stand-alone PEEK cage without pedicle screw fixation. The affected levels were L2–3 in 2 cases, L3–4 in 8 cases, L4–5 in 18 cases and L5–S1 in 12 cases. On 18th month follow-up, significant decrease in leg pain, LBP and ODI scores was detected (p < 0.001). This technique produced satisfying clinical enhancement in residual LBP, accepted radiological outcome such as maintaining the proper intervertebral disc space and prevention of recurrent disc herniation.

使用无椎弓根螺钉固定的单个 PEEK 保持架治疗腰椎间盘突出症的后路腰椎椎间融合术;梅努菲亚大学医院的初步经验
腰椎间盘切除术初期临床效果良好,但由于慢性腰痛和复发性椎间盘突出症,其长期成功率降至 40-80%。目的:评估单侧独立 PEEK(聚醚醚酮)椎体后路椎体间融合术治疗单侧腰椎间盘突出症的临床效果。自 2016 年 1 月至 2021 年 1 月,对 40 名腰椎间盘突出症患者(男性 24 人,女性 16 人)进行了回顾性研究。随访一直持续到 2021 年 12 月。所有患者均患有单侧腰椎间盘突出症,均接受了后路腰椎椎体间融合术和单侧独立 PEEK 保持架(无椎弓根螺钉固定)治疗。2例患者的受累椎体水平为L2-3,8例患者的受累椎体水平为L3-4,18例患者的受累椎体水平为L4-5,12例患者的受累椎体水平为L5-S1。随访 18 个月后,腿痛、腰痛和 ODI 评分均明显下降(P < 0.001)。该技术在改善残余椎间盘突出症方面取得了令人满意的临床效果,在保持适当的椎间盘间隙和预防复发性椎间盘突出症方面也取得了公认的放射学结果。
