Abstract:
Objective To investigate the clinical application value of Quadrant system combined with percutaneous pedicle screw fixation for treatment of lumbar degenerative disease.Methods The clinical data of 40 patients who sufferred from lumbar degenerative disease,were randomly divided into two groups:Quadrant system combined with percutaneous pedicle screw fixation to do discectomy and intervertebral bone graft fusion as invasive group (n =20),traditional posterior lumbar interbody fusion as conventional group (n =20).The operation time,length of incision,blood loss,postoperative drainage,JOA score of preoperation and postoperation,and effect (reforming Macnab standard) between two groups were recorded and compared.Results Operations were all well done in two groups.The operation time in invasive group was longer than that in traditional group [(147.3 ± 8.9) min,(136.7 ± 10.2) min,t =3.5,P ＜ 0.05].The length of incision [(3.65 ± 0.68) cm,(1 1.11 ± 1.29) cm,t =22.88,P ＜ 0.05)],blood loss [(205.00 ± 63.04) mL,(270.50 ± 77.58) mL,t =2.93,P ＜ 0.05],postoperative drainage [(90.3 ± 10.8) mL,(180.6 ± 1 3.9) mL,t =22.96,P ＜ 0.05] and days in hospital [(16.9 ± 2.0) days,(18.9 ± 2.1)days,t =3.05,P ＜ 0.05] in invasive group were all less.than those in traditional group (P ＜ 0.05).All cases had been followed up for 6-18 months,average of 13 months.There were no significant differences in excellent and good rate (reforming Macnab standard) between two groups in the last following up (P ＞ 0.05).There were no significant differences of JOA scores in preoperation [(12.0 ± 1.7) points,(11.0 ± 1.5) points,P ＞ 0.05],postoperative half a year [(22.0 ± 2.3) points,(21.0 ± 2.5) points,P ＞ 0.05],and postoperative one year [(23.0 ± 1.9) points,(22.0 ± 2.0) points,P ＞ 0.05].Conclusion Quadrant system combined withpercutaneous pedicle screw fixation is a safe,effective and minimally invasive surgical technique in treating lumbar degenerative disease.Compared with conventional group,invasive group has advantages such as less injury,less blood loss,simple operation,and good curative effect,which should be popularized.
