BackgroundLumbar 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.ObjectiveTo 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.MethodsA 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.ResultsThe 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).ConclusionsThis 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.
