Indications and effects of minimally invasive posterior approach single-segmental pedicle screw implantation on thoracolumbar fractures
Abstract：Objective To explore the indications and clinical effects of minimally invasive posterior approach single-segmental pedicle screw implantation on treatment of thoracolumbar fractures. Methods Twenty-one cases of thoracolumbar fractures receiving minimally invasive posterior approach single-segmental pedicle screw implantation surgery were collected in our hospital from March 2013 to November 2016 and their clinical data were analyzed retrospectively. CT and MRI showed no need for spinal canal decompression. The evaluations of indicators including intraoperative blood loss, operative time, average hospitalization time, postoperative complications, Visual Analogue Scale ( VAS) scores, Cobb's angle and height loss rate of anterior edge of injured vertebrae were analyzed. Results All the patients had a successful operation. No complications, such as internal fixation failure and nerve damage, were found after surgery. Nineteen patients were followed up and the median follow up was ( 17. 6 ± 5. 12) months ( ranges from 8 to 27 months). The mean operation time, intraoperative blood loss, and hospitalization time were ( 84. 28 ±20. 60) minutes, ( 140. 51 ± 56. 94) ml and ( 7. 28 ± 1. 69) days. The VAS scores decreased from preoperative average ( 7. 57 ± 0. 82) to postoperative average ( 2. 78 ± 0. 95) ( P ＜ 0. 05), the average loss rate of anteriov height of injured vertebrae decreased from ( 30. 53 ± 7. 88) ％ before operation to ( 5. 52 ± 1. 53) ％ after operation ( P ＜ 0. 05), the Cobb's angle of kyphosis decreased from ( 18. 47 ± 4. 18) ° to ( 5. 84 ± 1. 69) ° after operation ( P ＜ 0. 05). At the last follow-up, the average VAS scores were ( 1. 26 ± 0. 44) points, and the average loss rate of injured vertebrae was ( 7. 26 ± 1. 74) ％, and the average Cobb' s angles of kyphosis were ( 7. 53 ± 1. 98) °, with significant differences compared with those before operation. Conclusion Minimally invasive approach single-segmental pedicle screw implantation has a satisfactory clinical effect on treatment of thoracolumbar fractures. It has the advantages of small trauma, less bleeding and short hospitalization time.
