Primary Outcome Measures:
  • Infection rate [ Time Frame: 2 years ] [ Designated as safety issue: No ]
    Rate of postoperative wound edge necrosis and superficial or deep infection determined by wound redness, secretion of pus, detection of a microbial agens, CRP elevation and detection of fluid by sonography.


Secondary Outcome Measures:
  • Microcirculation, inflammation and functional clinical outcome [ Time Frame: 2 years ] [ Designated as safety issue: No ]
    clinical (computer-assisted movement analysis, functional scores) and radiographic (Böhler angle, arthritis signs)control measure of cytokine level, microcirculatory parameters

Detailed Description:

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.
