Abstract:Objective To explore the clinical value of unilateral injured vertebra fixation combined with short-segment fixation in the treatment of thoracolumbar burst fractures.Methods We compared blood loss,operative time,kyphosis angle and vertebral height ratio of the unilateral injured vertebra fixation group Ⅰ(41 cases) with bilateral injured vertebra fixation group Ⅱ(34 cases). All these cases were admitted in our hospital from September 2011 to July 2015.Results All of the operations were successfully completed,409 screws were inserted.The average healing time of the fracture was 15.6 months(from 12 to 24 months).There were no cases whose neurological impairment got worse.The 11 cases preoperative with incomplete neurological impairment got full recovery after operation.No breakage、loosening and exit of internal fixation occurred during the follow-up.There were no cases whose kyphosis lost more than 10 degrees.The operative time,blood loss of the two groups had no statistically difference(P>0.05).Their postoperative vertebral height ratio and kyphosis angle of the two groups compared with preoperative were statistically significant(P<0.05).1 year follow-up had no statistically difference compared with 1 week follow-up(P>0.05).1 week follow-up of their vertebral height ratio and kyphosis angle had no statistically difference compared with each other (P>0.05). Conclusion Injured vertebra fixation combined with short-segment fixation for thoracolumbar burst fractures can improve the kyphosis,rectify with vertebral compression,avoid the lost of reduction and reduce the complication of implant.Unilateral or bilateral injured vertebra fixation can achieve the same effects.
