• 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.
