•We present a case of L5/S1 Meyerding Grade III fixed spondylolisthesis managed by minimally invasive TLIF with percutaneous screws. Surgical techniques and key steps for reduction are described in detail.•The patient’s symptoms subsided after the surgery, and the CT scan in postoperative one-and-half year demonstrated complete reduction with fusion.•Minimally invasive TLIF is a viable option for reduction of high-grade spondylolisthesis at L5/S1.
ObjectiveTo demonstrate the feasibility and efficacy of reduction of high-grade lumbosacral spondylolisthesis via a minimally invasive approach.Summary of background dataReduction of high-grade spondylolisthesis remains controversial and technically challenging. Although minimally invasive transforaminal lumbar interbody fusion (MI-TLIF) has gained wide acceptance in recent years, it still has not been reported to achieve complete reduction of high grade slips.MethodsIn this technical note, the authors present a case of L5/S1 Meyerding Grade III fixed spondylolisthesis managed by MI-TLIF with percutaneous screws. Surgical techniques and key steps for reduction are described in detail.ResultsA 50-year-old woman had low back pain for 8 years. She also presented with radiculopathy of lower limbs and frequency/urgency of urination. The radiographs and computed tomography (CT) of the lumbar spine demonstrated degenerative spondylolisthesis, Meyerding grade III, at the level of L5/S1. The slippage was fixed on dynamic radiographs and there was neuroforaminal stenosis on the magnetic resonance image. The patient underwent MI-TLIF with percutaneous pedicle screw-rod fixation for arthrodesis at L5/S1. Her symptoms subsided after the operation. The one-and-half year follow-up radiographs, including CT, demonstrated complete reduction of the high-grade slippage and fusion of the lumbosacral spondylolisthesis.ConclusionMinimally invasive TLIF is a viable option for reduction of high-grade spondylolisthesis at L5/S1.
