A 68 year old female who had occult instability at a symptomatic osteoporotic L1 burst fracture was diagnosed by manual axially loaded magnetic resonance imaging. Traction resulted in the reduction of the fracture and decompression of the conus. Based on these findings, the patient underwent L1-L2 fusion with complete resolution of her back and leg pain. Our objective is to describe the utility...

Collet-Sicard syndrome is a rare condition characterized by the unilateral paralysis of the 9th through 12th cranial nerves. We describe a case of a 46-year-old man who presented with dysphagia after a falling down injury. Computed tomography demonstrated burst fracture of the atlas. Physical examination revealed decreased gag reflex on the left side, decreased laryngeal elevation, tongue devia...

Acoustic emission behavior during fatigue deformation and fracture was investigated in Al-Mg-Si alloys for automotive body panels. Generation of fatigue cracks was clearly identified by the burst of AE signals at the early stage of fatigue test. During the middle stage of fatigue, AE signals having low amplitude about 60dB corresponding to the propagation of striations appeared continuously. At...

The temporal evolution of mechanical energy and spatially averaged crack speed are both monitored in slowly fracturing artificial rocks. Both signals display an irregular burstlike dynamics, with power-law distributed fluctuations spanning a broad range of scales. Yet, the elastic power released at each time step is proportional to the global velocity all along the process, which enables defini...

Traumatic anterior dislocation of the hip is rare. Bilateral traumatic anterior dislocation is an even rarer injury; indeed, only 5 cases have been reported in the English literature. We describe a case of a bilateral traumatic anterior dislocation of the hip and a concomitant unstable lumbar burst fracture following a mechanism of injury distinctly different from other reports.

Background: Thoracolumbar burst fracture is one of the most common spinal traumas. It was still indeterminate whether short-segment (SS) fixation was more effective and preferable than long-segment (LS) fixation. We therefore conducted this meta-analysis to assess the comparative safety and efficacy of SS and LS fixation for the treatment of thoracolumbar burst fracture. Methods: A literature s...

OBJECTIVE The purpose of this prospective study was to evaluate the efficacy and safety of screw fixation without bone fusion for unstable thoracolumbar and lumbar burst fracture. METHODS Nine patients younger than 40 years underwent screw fixation without bone fusion, following postural reduction using a soft roll at the involved vertebra, in cases of burst fracture. Their motor power was in...

AIM Our aim was to determine whether a combination of sagittal index (SI), canal compromise (CC), and loss of vertebral body height (LVBH) is associated with the severity of neurological injury in patients with thoracolumbar burst fractures. MATERIALS AND METHODS Seventy-four patients with thoracolumbar burst fracture undergoing instrumentation between 2010 and 2015 were analyzed retrospectiv...

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...

BACKGROUND The mechanical response of the spinal cord during burst fracture was seldom quantitatively addressed and only few studies look into the internal strain of the white and grey matters within the spinal cord during thoracolumbar burst fracture (TLBF). The aim of the study is to investigate the mechanical response of the spinal cord during TLBF and correlate the percent canal compromise ...
