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.

Measurement of Angulation after Treatment of Fractures of the Tibia: Comparison of Conventional Methods and New Method Using Mechanical Axis: Chul Yong Chung, Chan Young Son, Sun Bon Koo, Sang Eun Kim; J Korean Soc Fract 1998;11(4):912-917.

Abstract PDF: The importance of residual angular deformity after tibial fracture is still uncertain. but it is generally assumed that osteoarthritis of the ankle and the knee will result when the deformity is severe. Therefore accurate measurement of the alignment of the tibia is important clinically and in research. We compared the results of conventional methods (method 1,2) of measuring the angulation deformity after a fracture of the shaft of the tibia, with a new method using mechanical axis reported by Milner11) (method 3). Sixty-seven patients of tibial fractures with angulation deformity treated at sei Gang General Hospital from January 1995 to December 1996 were evaluated. Samples of 20 sets of standard AP and lateral radiographs of both tibia were measured. The results obtained were as follows. 1. The difference between the angles obtained by Milner's new method (method 3) and conventional methods (method 1,2) was significant in all planes. 2. Both the mean intra-& interobserver difference were minimal in new method, compared with conventional methods, t all planes. 3. There is no statistically significant difference using by paired T-test between angles obtained by new method and conventional methods (p>0.05). From these results, an angulation of measuring the new method was accurate and has good inter- and intraoesrver reliability.
