Abstract:
Objective To assess the minimally invasive surgical therapeutic result of percutane-ous pedicle screw fixation using Sextant-R system in treating thoracolumbar fractures. Methods A to-tal of 36 patients with thoracolumbar fractures were divided into two groups, ie, Sextant-R pereutaneous pedicle screw fixation group (Sextant-R group, 14 patients) and open pedicle screw fixation group (open surgery group, 22 patients). A comparative study was done on surgical incision, operation duration, sur-gical blood loss and deformity correction. Results In Sextant-R group and open surgery group respec-tively, the incision size was (7.1±0. 9) cm and (16.8 ± 1.6) cm (P <0. 05), operation duration (1.1±0.7) hoursand (2.4 ±0.8) hours (P<0.05), surgical blood loss (89.3 ±12.1) ml and (325.0±123.6) ml (P < 0.01), surgical draining loss (12.6 ± 3.2) ml and (147.3 ± 36.1) ml (P < 0. 01), postoperative improvement of Cobb' s angle (4.5 ± 2.4)° and (1.0± 2.3)° (P < 0. 05), sag-ittal index (10.2 ± 10.1)° and (5.5 ± 8.6)° (P < 0.05) and anterior height of fracture vertebral body (85.0 ±7.0)% and (95.5 ±2.2)% (P <0.05). Conclusion Pereutaneous pediele screw fixation using Sextant-R system is a good minimally invasive surgical choice for patients with thoracolumbar frac-ture under strict control of surgical indications.
