Abstract
Objective To analyze microsurgical treatment of minimally invasive transforaminal interbody fusion (MIS-TLIF) through bilateral Wiltse approach for spondylolisthesis.Methods Between May 2012 and November 2013,13 patients diagnosed lumbar spondylolisthesis (Myerding Grade Ⅰ-Ⅱ) were included.With the assistant of neurophysiological monitoring and microscope,all patients were treated by MIS-TLIF through bilateral Wiltse approach (gap between the multifidus and the longissimus).Operation time,blood loss,postoperative wound pain duration and Lumbocrural pain relief time were analyzed.Creatine phosphokinase (CPK-MM) level was recorded preoperatively,1 day,3 days and 7 days postoperatively.Japanese Orthopaedic Association (JOA) score and visual analog scale (VAS) score were analyzed preoperatively,1 week,3 months and 6 months postoperatively.X-ray examination and MR imaging of lumbar spine were achieved preoperatively and 6 months postoperatively to assess slippage reset and nerve decompression.Lumbar CT three-dimensional reconstruction was used to confirm pedicle placement and spinal stability.Results All patients accepted successful operation without nerve injury.The blood loss was (185.3 ±26.3) ml,and operating time was (186.0 ±23.0) min.Postoperative lumbar X-ray examination and MRI scan demonstrated good slippage reset and complete nerve decompression.Postoperative lumbar CT three dimensional reconstruction showed accurate pedicle placement and good spinal stability.VAS,JOA score obviously improved in postoperative 1 week,3 months and 6 months compared with that before operation(P ＜0.05).CPK-MM level peaked at postoperative 1 day,then gradually reduced,and almost descended to preoperative level at postoperative 7 day.Conclusions MIS-TLIF technique has obvious advantages over operating time,blood loss,paraspinal muscle protection and improvement of clinical symptoms.It is feasible and clinically effective of MIS-TLIF through bilateral Wiltse approach for lumbar spondylolisthesis with the assistance of microscope and neurophysiological monitoring.
