A Research On Early Postoperative Ambulation And The Imaging Effect Of Thoraeolumbar Fracture

ObjectiveTo study the affect of early postoperative ambulation for the loss of vertebral height and reposition after posterior internal fixation of thoraeolumbar fracture.MethodsBetween January 2011 and June 2013.63patients with thoraeolumbar fracture were treated by pedicle screw fixation.The patients were divided into 2 groups:Observation group were allowed ambulation two weeks after surgery by protection of waist brace. Matched group were demanded whole bedridden rest for 4 weeks after operation afterward were allowed ambulation by protection of waist brace. The anterior height of vertebral body and the Cobb’s angle were respectively measured at five different stages:after injury, postoperation, following-up 3 month after operation, following-up 6 month after operation, following-up 1 year after operation(Do not remove the internal fixation).ResultsTwo groups of patients appear loss of vertebral height and reposition. The observation group was more serious. The loss of height of vertebral body and the Cobb’s angle after the operation to 3 months,3 months to 6 months were different (P<0.05). The loss of height of vertebral body and the Cobb’s angle 6 months to lyear were’t clear different (P>0.05)ConclusionEarly postoperative ambulation can aggravate the loss of vertebral height and reposition after posterior internal fixation of thoraeolumbar fracture.
