Analysis on curative effect of percutaneous minimally invasive spinal internal fixation with pedicle screw rod system for thoracolumbar fracture

Objective: Analyze the clinic treatment effect of thoracolumbar fracture by using the percutaneous minimally invasive spinal internal fixation with pedicle screw rod system. Method: Collect data from 62 thoracolumbar fracture patients treated in our hospital in March 2012-2013 as the research object and divide the patients into the observation group and contrast group randomly. Each group includes 31 patients. 4-screw internal fixation method is used for treatment in the contrast group. The internal fixation of the percutaneous mini-traumatic spinal pedicle screw rod is used for treatment in the observation group. The clinic effect of two groups are analyzed and compared. Results: The movement start time and hospitalization time of the observation group is significantly less than that of the contrast group (P<0.05). The in-operation bleeding amount of the observation group is significantly less than that of the contrast group (P<0.05). The ASIA score of the observation group is significantly higher than that of the contrast group (P<0.05). 3 patients suffering from complications in the observation group, including one patient with loose screws, one patient with cut infection and one patient with venous thrombosis. The occurrence rate of the complication is 9.68%. 12 patients suffer from complication in the contrast group, including three patients with loose screws, four patients with cut injection, two patients with venous thrombosis and three patients with crackled screws. The occurrence rate of the complication is 38.71%. The complication occurrence rate of the observation is significantly less than it of the contrast group (P<0.05). Conclusions: The clinical treatment of thoracolumbar fracture based on the internal fixation of percutaneous mini-traumatic spinal pedicle screw rod system is better, this method can effectively shorten operation time and hospitalization time, reduce the bleeding and reduce the occurrence rate of complication, so this method is worthy of application in the clinic treatment.
