Abstract

Purpose: To study the therapeutic effect of percutaneous pedicle screw fixation (PPSF) combined with Tongdu Huoxue decoction on thoracolumbar spine fractures. Methods: Ninety-eight patients with thoracolumbar spine fractures treated with PPSF were retrospectively enrolled and grouped into a study group (SG, n = 51, PPSF combined with THD), and a control group (CG, n = 47, PPSF). General surgical indices, postoperative pain, postoperative Oswestry dysfunction index (ODI index), preoperative and postoperative imaging indices, and postoperative hemodynamic indices were determined and recorded. Results: Patients in SG exhibited significantly lower visual analog scale (VAS) scores higher than those of CG at 3, 7 and 15 days after surgery (p < 0.05). At 15 and 30 days after surgery, patients in SG exhibited significantly lower ODI index than those in CG (p < 0.05). At day 60 after surgery, Cobb angle was lower in SG than in CG, while the injured vertebral body showed higher anterior height in SG than in CG. Furthermore, FIB and D-D were lower in SG than in CG at day 7, but exhibited higher PT than CG (p < 0.05). Conclusion: The combined application of PPSF and THD in patients with thoracolumbar fractures ameliorates postoperative pain levels, improves short-term spinal function, and significantly alters the postoperative coagulation index of patients, presumably by reducing the incidence of postoperative thrombosis. However, there is a need for further clinical trials prior to the introduction of this therapy into clinical practice.

Abstract

Multi-ply woven fabric consists of many layers and can be used to form three-dimensional shapes, which finds its application in a variety of end-uses. One of the advantages is that this type of products requires no seams or cuts. This paper presents a novel method to facilitate the design of 3D rectangular box-shaped fabrics made of multi-ply weaves. A preliminary folding-down process is a must for fabric manufacture and two folding approaches were developed accordingly. Approach A has been found to be more suitable for boxes with X ≥ 2Z. The elimination of quadruple-layer fabric region simplifies the design and weaving process. In this regard, plain weave was used sections form box body and basket weave was employed for bound-layer regions so that fabric recoiling could be avoided. The diagonal lines connecting the bound-layer and double-layer regions is required to have an angle of 45°, and hence a Jaquard loom was in use for manufacturing. As the fabric is formed by different parts, thread density varies, leading to uneven yarn tension. This problem can be solved using additional warp beams. Approach B requires the two side planes to be folded in, the design process of which is similar to that of approach A. Theoretically, boxes with multiple cells could also be designed using this technique. Approach A has been found to be able to deal with boxes of various geometrical parameters. One problem of the 3D fabric is the soft edges, which requires further investigations. [ABSTRACT FROM AUTHOR]
