Comparison of Percutaneous versus Open Pedicle Screw Fixation for Treating Unstable Thoracolumbar Fractures: Jin Young Han, Ki Youn Kwon; J Korean Fract Soc 2020;33(1):1-8. Published online January 31, 2020; DOI: https://doi.org/10.12671/jkfs.2020.33.1.1

PURPOSE
This study compared the clinical and radiological results between two groups of patients with percutaneous fixation or conventional fixation after hardware removal.
MATERIALS AND METHODS
The study analyzed 68 patients (43 open fixation and 43 percutaneous screw fixation [PSF] 25) who had undergone fixation for unstable thoracolumbar fractures. The radiologic results were obtained using the lateral radiographs taken before and after the fixation and at the time of hardware removal. The clinical results included the time of operation, blood loss, time to ambulation, duration of the hospital stay and the visual analogue scale.
RESULTS
The percutaneous pedicle screw fixation (PPSF) group showed better results than did the conventional posterior fixation (CPF) group (p<0.05) in regard to the perioperative data such as operation time, blood loss, and duration of the hospital stay. There were no significant differences in wedge angle, local kyphotic angle, and the Î”Kyphotic angle on the postoperative plane radiographs between the two groups (p>0.05). There were no significant differences in the wedge angle and local kyphotic angle after implant removal (p>0.05) between the two groups as well. However, there were significant differences in the segmental montion angle (p<0.001), and the PPSF group showed a larger segmental motion angle than did the CPF group (CPF 1.7Â°Â±1.2Â° vs PPSF 5.9Â°Â±3.2Â°, respectively).
CONCLUSION
For the treatment of unstable thoracolumbar fractures, the PPSF technique could achieve better clinical results and an improved segmental motion angle after implant removal within a year than that of the conventional fixation method.

Change of Kyphotic Angle in Posterior Pedicle Screw Fixation for Thoracic and Lumbar Burst Fractures: Comparison Study by the Screw Fixation Level: Jeong Gook Seo, Jong Ho Park, Jeong Seok Moon, Woo Chun Lee; J Korean Fract Soc 2009;22(1):39-44.

Abstract PDF: PURPOSE
To evaluate the relationship between the level of screw fixation and the stability of the segment of endplate fracture after posterior pedicle screw instrumentation for thoracic and lumbar burst fractures.
MATERIALS AND METHODS
The 41 patients of burst fractures who had been operated with pedicle screw instrumentation were retrospectively evaluated. The patients were divided into two groups by the levels of screw fixation. One group was treated with screws fixed by one-level to the direction of fractured endplate (One-level group, 16 cases). The other group was treated with screws fixed by two-level to the direction of endplate fracture (Two-level group, 25 cases). The two groups were compared by the radiographic changes of kyphotic angle between the day of surgery and 6 months after surgery.
RESULTS
At the 6 months, one-level group showed the change of kyphotic angle of 17.5+/-2.4 degrees, which was different from two-level group of 5.2+/-0.8 degrees (p=0.000).
CONCLUSION
In posterior pedicle screws fixation for thoracic and lumbar burst fractures, 2 vertebrae to the direction of the endplate fracture should be included to prevent the postoperative kyphotic change.
