REVIEW
Ricky Raj S Kalra, Meic H Schmidt
Thoracoscopic spinal surgery is a minimally invasive open endoscopic approach to the anterior thoracolumbar spine for decompression and stabilization. It offers an alternative to open thoracotomy for thoracolumbar burst fractures, anterior spinal cord decompression, and spinal reconstruction with interbody and anterolateral plate instrumentation for restoration of biomechanical stability and alignment. Posterior instrumentation may not sufficiently stabilize a significantly disrupted anterior load-bearing spinal column, and the high access morbidity of open procedures is of significant concern...

STUDY DESIGN: Cost-utility analysis (CUA). OBJECTIVE: Determine the cost-effectiveness of pedicle screw removal after posterior fusion in thoracolumbar burst fractures. SUMMARY OF BACKGROUND DATA: Pedicle screw instrumentation is a standard fixation method for unstable thoracolumbar burst fracture. However, removal of the pedicle screw after successful fusion remains controversial because the clinical benefits remain unclear. CUA can help clinicians make appropriate decisions about optimal healthcare for pedicle screw removal after successful fusion in thoracolumbar burst fractures...

BACKGROUND: A review of the literature showed that posterior short-segment fixation including the fractured vertebra (PSFFV) has better outcomes in the treatment of thoracolumbar burst fractures(TBFs) than patients with short-segment pedicle screw fixation(SSPF) alone. However, its efficacy in mild TBFs with load-sharing scores of 3 and 4 points has not been specifically analyzed. The aim of this study was to compare the clinical, functional and radiologic results of PSFFV with SSPF for mild TBFs and to determine whether the screws in the fractured vetebra were necessary for these patients...

The intraosseous fluid sign (IFS) in chronic osteoporotic vertebral fractures is attributed to fluid accumulation within non-healing intervertebral clefts. IFS can also be seen in acute traumatic fractures, not previously described. We hypothesize a pathophysiological mechanism for the acute traumatic intraosseous fluid sign (ATIFS) and its predisposition to dynamic fracture mobility with axial loading on upright radiographs. Retrospective analysis was performed of 41 acute thoracic and lumbar compression or stable burst fractures with both supine CT and upright plain films completed within 1 week of each other...

BACKGROUND: The objective of this study is to identify the independent risk factors of neurologic deficit after thoracolumbar burst fracture. Traumatic fractures of the thoracolumbar spine are the most common type of spinal column fractures. Many studies have attempted to determine whether neurologic deficit in such fractures is related to spinal canal stenosis or other parameters observed on axial computed tomography. However, this relationship remains controversial. METHODS: A review of the clinical data and axial computed tomography (CT) for 105 patients was performed...

Traumatic neurologic injury in contact sports is a rare but serious consequence for its players. These injuries are most commonly associated with high-impact collisions, for example in football, but are found in a wide variety of sports. In an attempt to minimize these injuries, sports are trying to increase safety by adding protection for participants. Most recently is the seemingly 'safe' sport of Bubble Soccer, which attempts to protect its players with inflatable plastic bubbles. We report a case of a 16-year-old male sustaining a cervical spine burst fracture with incomplete spinal cord injury while playing Bubble Soccer...

INTRODUCTION: The thoracic cage is an anatomical entity composed of the upper thoracic spine, the ribs and the sternum. The aims of this study were primarily to analyse the combined injury pattern of thoracic cage injuries and secondarily to evaluate associated injuries, trauma mechanism, and clinical outcome. We hypothesized that the sternal fracture is frequently associated with an unstable fracture of the thoracic spine and that it may be an indicator for unstable thoracic cage injuries...

A generalized Rayleigh-Plesset-type bubble dynamics model with a damage mechanism is developed for cavitation and damage of soft materials by focused ultrasound bursts. This study is linked to recent experimental observations in tissue-mimicking polyacrylamide and agar gel phantoms subjected to bursts of a kind being considered specifically for lithotripsy. These show bubble activation at multiple sites during the initial pulses. More cavities appear continuously through the course of the observations, similar to what is deduced in pig kidney tissues in shock-wave lithotripsy...

STUDY DESIGN: Retrospective comparative clinical case series. OBJECTIVE: Burst C2 fractures are very rare. Treatment options include conservative treatment or fusion (anterior, posterior, or anterior and posterior). Anterior fusion addresses mainly hangman component. The bursting body usually needs posterior or combined anterior-posterior fusion, but both permanently sacrifice atlantoaxial motion. Can anterior-"first" approach preserve C1-C2 motion and restore function? METHODS: We report nine cases of burst C2 combined with C2-C3 spondylolisthesis and an odontoid fracture...

BACKGROUND: The surgical management of thoracolumbar burst fractures frequently involves posterior pedicle screw fixation. However, the application of short- or long-segment instrumentation is still controversial. The aim of this study was to compare the outcome of the short-segment fixation with inclusion of the fracture level (SSFIFL) versus the traditional long-segment fixation (LSF) for the treatment of unstable thoracolumbar junction fractures. METHODS: From December 2009 to February 2014, 60 patients with unstable thoracolumbar junction fractures (T11-L2) were divided into two groups according to the number of instrumented levels...

Open surgery is currently the main treatment method for the lumbar burst fracture with neurological deficit but may irreversibly disrupt the lumbar anatomy. The minimally invasive surgery (MIS) techniques have recently gained increasing attention. However, their use is still limited to lumbar burst fractures mainly due to their difficulties in burst fracture reduction and decompression. Here we present a novel bio-inspired MIS device which can be used with an endoscope to reset the bone fragments retropulsed into the spinal canal within the wounded vertebral body...

Here, we introduce a simple and fast method for bonding a poly(dimethylsiloxane) (PDMS) silicone elastomer to different plastics. In this technique, surface modification and subsequent bonding processes are performed at room temperature. Furthermore, only one chemical is needed, and no surface oxidation step is necessary prior to bonding. This bonding method is particularly suitable for encapsulating biomolecules that are sensitive to external stimuli, such as heat or plasma treatment, and for embedding fracturable materials prior to the bonding step...
