Abstract:
Objective Explore the spine fractures treated by percutaneous one-way pedicle screws surgery compared with curative effect of traditional open surgery.Methods From October 2012 to October 2015,to collect 61 patients with single segmental thoracolumbar fractures were retrospectively analyzed,respectively for percutaneous minimally invasive one-way long tail pedicle screw(Observation group,n =32) of internal fixation were compared with traditional open surgery (control group,n =29).Compare two groups of paticnts in the differences of operation time,amount of operative bleeding,operative wound,postoperative VAS scores,the ratio of postoperative injured vertebral front height,and hospitalization expenses.Results All patients were followed up for an average of 9.6 months (from 7 to 14months),neither of the groups showed internal fixation of related complications.Time of operation(min):observation group(87.4 ± 13.6) min,control group (92.3 ± 10.3) min,(t =-1.648,P ＞ 0.05);Mount of operative bleeding:observation group (73 ± 8.8) mL,control group (352 ± 63.7) mL,(t =-23,385,P ＜ 0.05);Wound of operative (cm2):observation group (12.3 ± 2.30) cm2,control group (81.5 ± 14.2) cm2,(t =-25.937,P ＜ 0.05);Expenses of hospitalization (RMB ten thousand):observation group (3.5 ± 0.3),control group(2.3± 0.5),(t =-11.223,P ＜ 0.05);VAS score 2 days and 6 months after surgery:observation group (3.0±0.4) and (1.3±0.6),controlgroup(4.2±0.5) and (2.7±0.7),(t=-10.396 and-8.409,P＜ 0.05),and comparcd with the preoperative also statistically significant (P ＜ 0.05);2 days and 6 months after surgery in the ratio of injured vertebral front height:observation group(89.6 ±7.2)％ and (84.2 ±5.7)％,control group (91.3 ± 5.8) ％ and (86.3 ± 4.6) ％,(t =-1.009 and-1.573,P ＞ 0.05),but in the same group recovery of injured vertebral leading edge height ratio compared with preoperative postoperative were significantly (P ＜ 0.05).Conclusion For a single section of thoracolumbar spine fracture,Compared with the control group,Percutaneous one-way long tail pedicle screw internal fixation technology have the advantage of little trauma,less sequel,rapid postoperative recovery,also in the recovery of vertebral body height and loss of late has achieved the same cur-ative effect,but patients with costly.
