Abstract：Objective To observe the efficacy and safety of minimally invasive percutaneous pedicle screws osteosynthsis ( MIPPSO ) combined with axial lumbar interbody fusion ( AxiaLIF ) for lumbar 5 spondylolisthesis (L5S).Methods Thirty-six cases of L5S below Ⅱdegree admitted in our hospital from Jul.2011 to Jun.2014 were screened out .There were 2 cases of traumatic lumbar spondylolisthesis , 20 cases of isthmus broken lumbar spondylolisthesis , and 14 cases of elderly degenerative lumbar spondylolisthesis .Among them 18 cases were treated with MIPPSO combined with AxiaLIF ( the observation group ) and another 18 were treated with traditional open sur-gery ( the control group ) .VAS score of low bac pain , Taillard index , intervertebral space height , slip angle and fu-sion were compared , and the blood loss ,operative time ,follow-up time and complications were recorded .Results All patients were followed up for 10 -26(13.87 ±6.17) months.The average operation time of the observation group and the control group was (143.86 ±39.34) min and (213.46 ±29.12)min, respectively.The mean blood loss of the observation group and the control group was (73.54 ±21.03) mL and (101.31 ±25.31) mL, respec-tively.VAS before the surgery in the observation group and the control group was (7.28 ±1.49) and (9.11 ± 2.03) , respectively, and (0.65 ±0.78) and (2.12 ±0.91) after surgery, and the difference before the surgery and after the surgery had statistical significance .There were significant differences among these three indicators ob-served before the surgeries and those observed 1 week after surgery and in the last follow-up.Complete bony fusions were shown in the three-dimensional reconstruction of the 18 patients after CT scan six months after the surgeries . The Taillard index of the observation group and the control group before the surgery was (0.1719 ±0.03821) and (0.1632 ±0.04031) , respectively, (0.0697 ±0.008) vs (0.0783 ±0.007) one week after the surgery and (0.0715 ±0.007) vs (0.0932 ±0.005) at the last follow-up.The slip angle before the surgery of the observation group and the control group was (5.28 ±1.41)°vs (5.32 ±1.29)°, respectively, and (2.09 ±0.58)°vs (3.41 ±0.69)°one week after the surgery and(2.17 ±0.52)°vs (3.72 ±0.61)°at the last follow-up.The interverte-bral space height before the surgery of the observation group and the control group was (4.81 ±1.52) mm vs (4.33 ±1.87) mm, respectively, (9.68 ±1.73) mm vs (7.73 ±2.15) mm one week after the surgery and (9.55 ± 1.26)mm vs (7.45 ±1.96)mm at the last follow-up.The above three indicators before surgery were all of statisti-cal significance (P<0.05)compared with those 1 week after the surgery.The above three indicators 1 week after the surgery in the observation group were all of statistical significance (P<0.05)compared with those in the control group .Conclusion Minimally invasive percutaneous pedicle screws osteosynthsis combined with axial lumbar inter -body fusion is minimally invasive and ideal in treating lumbar 5 spondylolisthesis with quick fusion and good results .
