Abstract:
Objective To investigate the clinical effect of minimally invasive transforaminal lumbar interbody fusion(Mis-TLIF)technique combined with preoperative position reduction in the treatment of spondylolisthesis and summarize its advan-tages.Methods Between July 2016 and July 2022,60 patients with lumbar isthmic spondylolisthesis were retrospectively ana-lyzed,including 26 males and 34 females,with an average age of(51.32±4.24)years old ranging from 35 to 72 years old.They were divided into observation group and control group according to the operation methods.There were 30 patients in the obser-vation group,including 12 males and 18 females;the age ranged from 35 to 71 years old with an average of(51.80±6.38)years old,the course of disease ranged from 12 to 60 months with an average of(24.17±1.98)months;there were 18 cases of L4 spondylolisthesis and 12 cases of L5 spondylolisthesis;according to Meyerding classification,there were 20 cases of grade Ⅰspondylolisthesis and 10 cases of grade Ⅱ.The observation group was treated with preoperative postural reduction combined with intraoperative reduction assisted minimally invasive transforaminal lumbar fusion via Quadrant channel(Mis-TLIF).There were 30 patients in the control group,including 14 males and 16 females,with an average of(50.00±4.24)years old ranging from 36 to 72 years old;the course of disease ranged from 12 to 60 months with an average of(23.70±1.53)months;there were 16 cases of L4 spondylolisthesis and 14 cases of L5 spondylolisthesis;according to Meyerding classification,there were 19 cases of grade Ⅰ spondylolisthesis and 11 cases of grade Ⅱ.The control group was treated with open transforaminal lumbar interbody fusion(Open-TLIF).The differences of operation time,intraoperative and postoperative blood loss,hospital stay,radiation exposure time and complications between the two groups were analyzed.Visual analogue scale(VAS),Oswestry disability index(ODI)and Japanese Orthopaedic Association(JOA)score were used to evaluate the clinical effect.X-ray and CT were followed up to evaluate the interbody fusion.Results All patients were followed up for 12 months.There was no signifi-cant difference in operation time,VAS of low back pain,slip angle and slip rate between two groups(P＞0.05).The intraoperative and postoperative blood loss in the observation group(165.50±15.56)ml and(59.17±10.59)ml were less than those in the con-trol group(259.33±35.32)ml and(165.33±29.56)ml(P＜0.05).The length of hospital stay in the observation group(3.53±0.68)days was less than that in the control group(5.20±0.41)days(P＜0.05).The intervertebral space height,slip angle,slip rate,ODI,VAS and JOA scores were significantly improved in the two groups at the final follow-up(P＜0.05).There were signifi-cant differences in ODI[(9.93±1.11)％vs(10.93±1.11)％]and JOA[(26.07±1.01)points vs(25.43±1.25)points]between the observation group and the control group at the final follow-up(P＜0.05).Conclusion In the treatment of spondylolisthesis,preoperative position reduction combined with intraoperative reduction assisted Mis-Tlif technique has advantages of less trau-ma,less bleeding and shorter hospitalization period than traditional open surgery.It is a safe and effective technique.
