title: [Clinical effect of minimally-Invasive surgical-transforaminal lumbar interbody fusion technique associated with percutaneous pedicle screws in micro endoscopy discectomy].
abstract: Objective:To evaluate the clinical efficacy between the minimally-Invasive surgical (MIS)-transforaminal lumbar interbody fusion (TLIF) technique associated with percutaneous pedicle screws in micro endoscopy discectomyand MIS-TLIF technique associated with both sides of the lower lumbar spine Wiltse approach in Quadrant channel with treatment of single segment herniation associated with lumbar instability syndrome.Methods:From January 2012 to January 2015, 75 cases that meet the inclusion and exclusion criteria were treated by retrospective study method, which were divided into two groups in Department of Orthopedics, the Affiliated Hospital of Putian University.Experimental group(30 patients) were treated with MIS-TLIF technique associated with percutaneous pedicle screws in microendoscopy discectomy, control group were treated with MIS-TLIF technique associated with both sides of the lower lumbar spine Wiltse approach in Quadrant Chanel.Compare operation time, blood loss, postoperativehospital stay, clinical efficacy, nailing accuracy, fusion rate, postoperative pain scoring of two groups.Results:The blood loss[(102.1±5.5) min vs(103.7±7.7) min,t=-0.586,P>0.05], postoperative blood loss, hospital stay[(44.6±5.2) ml and(57.2±5.3) ml, (7.3±1.6) d and(9.3±1.9) d;t=-5.813, -2.774,P<0.05], JOA score before and after surgery in same group were statistically significant(P<0.05), respectively.Patients of two groups compared with operation time, clinical efficacy, nailing accuracy[group A: 97.5%, group B: 95.7%; χ(2)=3.00,P>0.05.Postoperative 3 month , group A: 96.7%(29/30), group B: 94.3%(33/35; χ(2)=0.79,P>0.05], fusion rate[group A: 96.7%(29/30), group B: 94.3%(33/35), χ(2)=0.79,P>0.05], preoperative JOA score[(20.4±2.4)score and(7.9±1.0), (19.1±2.7)score and(7.8±1.2)score], postoperative JOA score were no statistically significant respectively,P>0.05. JOA score of both groups were statistically significant respectively Before and after operate.Excellent rate: group A; 84.4%(25/30), group B: 80.0%(28/35), χ(2)=0.43,P>0.05.Conclusion:MIS-TLIF technique associated with percutaneous pedicle screws in micro endoscopy discectomy relative to conventional minimally invasive spine surgery had many advantages: minimal damage, operation conveniently, precisely clinical effect, that is a kind of feasible and reliable minimally invasive surgery which is worth promoting.
