Identification of Microcirculation and Inflammation After Posterior Stabilization of the Spine

2014-08-27 04:00:23 | BioPortfolio


In this project, with unstable vertebral fractures, the microcirculation of the skin and muscle (O2C,Laser-Doppler/White-light -Spectroscopy and contrast-enhanced sonography) will be evaluated in both conventional and in percutaneous minimally invasive technique (XIA versus Mantis) at the thoracolumbar junction.


In this project, with unstable vertebral fractures, the microcirculation of the skin and muscle (O2C,Laser-Doppler/Whitelight-Spectroscopy and contrast-enhanced sonography) will be evaluated in both conventional and in percutaneous minimal-invasive technique (XIA versus Mantis) at the thoracolumbar junction. And after placing a fixator, the inflammatory potency (laboratory chemicals, cytokines, immune status) and the muscular injury (EMG) of acess are examined.

The study is planned as a randomized prospective study. In the study a total of at least 100 patients should be included, 50 with minimally invasive fixation-implantation and 50 patients with conventional procedure.

The radiological imaging (post-surgical control, possibly after mobilization, CT) ist routinely.

The patient outcome is determined using established scores (clinical score, visual analogue scale, SF-12).

The study also indicates by comparing the damage of the microcirculation of the two surgical techniques to make statements on wound healing and muscle blood flow heavily in order to filter out the less complications and tissue-method.

In this research project, the limits in the microcirculation measurement with the O2C and contrast enhanced sonography be established at an early stage to help in future wound healing disorders can be treated so well.

An order of insects, comprising a single family (Mantidae), restricted almost entirely to the tropics. Only one species, the praying mantis (Mantis religiosa), is found in temperate habitats.

Implantable fracture fixation devices attached to bone fragments with screws to bridge the fracture gap and shield the fracture site from stress as bone heals. (UMDNS, 1999)

Splitting of the vessel wall in the VERTEBRAL ARTERY. Interstitial hemorrhage into the media of the vessel wall can lead to occlusion of the vertebral artery, aneurysm formation, or THROMBOEMBOLISM. Vertebral artery dissection is often associated with TRAUMA and injuries to the head-neck region but can occur spontaneously.
