RESUMO
Objective Pedode foxatoon at the level of fracture vetebral technology is widely used in rebuilding spnal fracture recently.The purpose of minimally invasive surgery for thoracolumbar fractures is to reduce the injury , fix segments, and rebuild the stability of the spine .This study aimed to investigate the short-term clinical effect of pedicle fixation at the fractured vertebra via the pa-ravertebral intermuscular approach for the treatment of thoracolumbar fractures . Methods We treated 24 cases of thoracolumbar fracture by pedicle fixation at the fractured vertebra via the paravertebral intermuscular approach , rebuilt spinal stability , and corrected kyphotic deformity .We evaluated the improvement of pain symptoms and life quality using The Visual Analogue Scale ( VAS) and The MOS 36-Item Short-Form Health Survey (SF-36), and assessed the corrected status of vertebral height loss and kyphotic deformity by radiographic measurement .All the patients were followed up for over 12 months. Results The VAS score of the patients was signifi-cantly higher while the SF-36 score remarkably lower before surgery than the scores in 12 months which were ([7.65 ±0.13] -[1.54 ±0.07], P<0.05) and ([90.21 ±2.02]-[117.21 ±1.02], P<0.05).Imaging evaluation showed desirable correction of the reduced height of the injured vertebrae and kyphotic deformity . Conclusion Pedicle fixation at the fractured vertebra via the pa-ravertebral intermuscular approach , with its advantages of minimal invasiveness and fewer segments of fixation , can effectively correct vertebral height reduction and kyphotic deformity .
