BACKGROUND Complications in posterior pedicle screw fixation using a conventional posterior approach for thoracolumbar fractures include vertebral height loss, kyphosis relapse and breakage, or loosening of instrumentation. The purpose of this study was to evaluate the clinical effects of transpedicular bone grafting and pedicle screw fixation in injured vertebrae using a paraspinal approach fo...

STUDY DESIGN Three types of anterior thoracolumbar multisegmental fixation were biomechanically compared in construct stiffness and rod-screw strain. OBJECTIVES To investigate the effects of rod diameter and rod number on construct stiffness and rod-screw strain in anterior thoracolumbar multisegmental instrumentation. SUMMARY OF BACKGROUND DATA No studies have been undertaken to investigat...

STUDY DESIGN Retrospective analysis of a prospectively collected patient database. OBJECTIVE To investigate the significance and relevant factors of postural kyphosis reduction during posterior surgical treatment of thoracolumbar burst fracture. SUMMARY OF BACKGROUND DATA Optimal reduction of kyphosis is a goal in the surgical treatment of thoracolumbar burst fracture. Several factors are k...

BACKGROUND Preoperative embolization decreases the intraoperative risk of hemorrhage in spinal decompression surgery of hypervascular metastases such as renal cell carcinoma. There is no consensus concerning embolization in other metastases. The purpose of this study was to compare the intraoperative amount of blood loss in embolized versus non-embolized patients, seeking for differences depend...

STUDY DESIGN Retrospective cohort analysis. OBJECTIVE To evaluate the economic impact of revision surgery for proximal junctional failures (PJF) after thoracolumbar fusions for adult spinal deformity (ASD). SUMMARY OF BACKGROUND DATA PJF after fusions for ASD is a major cause of disability. Although clinical sequelae are described, PJF-revision operation costs are incompletely defined. ME...

BACKGROUND Short-segment U-shaped pedicle screw fixation has been widely used to treat thoracolumbar burst fracture. Some studies have reported the disadvantages of traditional U-shaped pedicle screw, which included a relatively high rate of adjacent segment degeneration and screw failure, including screw pullout and breakage. The purpose of this study was to assess the efficacy of open reducti...

BACKGROUND Epidural anaesthesia is one of the most commonly used locoregional techniques in ruminants. The lumbosacral epidural technique is reasonably easy to perform and requires low volumes of local anaesthetic drug to allow procedures caudal to the umbilicus. However, surgical procedures in the flank of the animal would require an increased volume of drugs. The anaesthetized area provided b...

This study aimed to explore the clinical effects of percutaneous kyphoplasty combined with pedicle screw fixation on aged osteoporotic thoracolumbar burst fracture. 160 patients with aged osteoporotic thoracolumbar burst fracture treated at our hospital during January 2012 and January 2015 were enrolled. According to the digital meter method, they were randomly divided into two groups, the obse...

The average survival time of patients in the malignant phase of hypertension is short-eight months according to Keith et al. (1928). There have been many reports of the effects of bilateral thoracolumbar sympathectomy on the mortality rate in. this disease. Woods and Peet (1941) recorded a survival rate of 33 per cent five years after operation and Peet and Isberg (1946) a rate of 19 per cent a...

The aim of this retrospective clinical study was to evaluate and compare the results of the technique so called 'two above one below approach' with intermediate screws at the fracture site with long-segment posterior fusion in the surgical treatment of thoracolumbar burst fractures. For this purpose neurologically intact 27 patients having isolated one level thoracolumbar burst fracture underwe...
