Comparison Of The Treatment To Thoracolumbar Fracture With Injured Vertebra Pedicle Instrumentation And Cross Segment Pedicle Instrumentation

Objective: To investigate the fracture healing and loss of vertebral height in patients with lumbar vertebral compression fracture treated with different numbers of posterior short segment pedicle screw fixation.Methods: From January 2015 to December 2016,the patients with single-segment lumbar vertebral fracture treated with posterior short-segment pedicle screw fixation in our hospital were selected as the research objects.The cases of open fracture,pathological fracture,multiple-site fracture and osteoporosis were excluded.According to the screw placement of the injured patients,the patients were divided into four screw fixation groups [group A],six screw fixation groups [group B],four screw fixation groups [group A],and 35 male cases [group A].There were 26 females [61cases] with an average age of 38.1 years [31-59 years].Six screws were fixed in group B,29 males and23 females [52 cases],with an average age of 36 years [29-60 years].All the operations were performed by open reduction and internal fixation under general anesthesia.Antibiotics were given to prevent infection after operation,and bedridden for 1 month after operation.Postoperative follow-up for 1 year.Result: Vertebral height was recovered after operation in both groups.The effect of operation in group B was better than that in group A.Long-term height loss occurred in both groups.There was no statistical difference between group A and group B in long-term height loss.CONCLUSION: Posterior short-segment pedicle screw internal fixation for lumbar vertebral compression fracture is similar to that for trans-traumatic vertebra..
