Abstract

Purpose

Open book pelvic ring fractures are potentially life-threatening, due to their instability and major hemorrhage risk. During the open reduction and internal fixation, the pelvic approach remains a technical challenge, as the surgeon wants to prevent any iatrogenic damage of the vascular loop located in the retro-pubic area called corona mortis (CMOR). Recently, the cadaver perfused SimLife® technology has been developed to improve the surgeon training, out of the operating room. This study aimed to compare two models of cadaveric dissection, to assess the interest of the perfused SimLife® in providing dynamic aspect of anatomy in the identification of CMOR and its topography.

Methods

Twelve human cadaveric pelvises have been dissected, following two protocols. 12 hemi-pelvises of the dissections were performed without perfusion (Model A), whereas the 12 other hemi-pelvises have been prepared with the SimLife® pulsatile perfusion (Model B). The prevalence and morphologic parameters determined: length, diameter and distance between the CMOR and the pubic symphysis.

Results

The CMOR has been found in 66.67% of the cases. The length, the diameter, and the distance between the CMOR and the pubic symphysis were significantly higher in model B (respectively p = 0.029, p = 0.01, and p = 0.022).

Conclusion

These results suggest that the CMOR is easier to identify and to dissect with the SimLife® perfusion. As part of the surgical training of any trauma surgeon, this model could help him to keep in mind the CMOR topography, to improve the open book lesion management.
