Application Of Non-fusion Internal Fixation Technique In The Treatment Of Thoracolumbar Fractures Of The Spine

Objective : To investigate the clinical efficacy of posterior stabilization of thoracolumbar spinal fracture using transpedicular internal fixation and nonfusion technique.Methods:Twenty-four patients with thoracolumbar spinal fractures received the treatment of transpedicular internal fixation and nonfusion technique were selected.After 10 to 18 months,the implants were removed from all patients after initial fracture fixation.All cases were followed up for at least 52 weeks.The cobb angle,the compressibility of vertebral anterior edgeand the stabilities and motions of thoracolumbar spinal in flexion /extension,right-left bending view were measured radiologically.Clinical aspects,subjective feelings and degrees of satisfaction were also investigated.Results:Before using transpedicular internal fixation and nonfusion technique,the cobb angle,the compressibility of vertebral anterior edge and the VAS score are respectively(13.19±17.66)°,(52.24±0.13)% and(7.33±1.37)scores.At final follow-up,the above three indices improve respectively to(8.21±9.92)°,(27.31±0.10)% and(0±0)point.And the results of inspection in statisticalbetween the two phases are significant(P<0.05).Conclusion:The nonfusion internal fixation technique can get better clinical efficacy in managing thoracolumbar spinal fractures.The choice of surgical indications is important.
