Digital model of the perforators and their relationships in the lumbar and gluteal regions
Objective To build digitized visible model of the perforators and their relationships, and to provide morphological data of an algorithm to safely elevate the cross-boundary perforator flaps in the lumbar and gluteal regions. Method Three bodies underwent whole body polyvinyl alcohol - cerium oxide injection, and one body was perfused with gelatin-lead oxide. The cadavers were scanned using a 64 row spiral CT. The computed tomographic data were transformed to digital imaging and communications in medicine format and imported to a personal computer. 3D-reconstructions of lumbar and gluteal regions were then performed using Materialise’s Interactive Medical Image Control System Software (MIMICS). Results The 3D reconstructed model of the lumbar and gluteal regions can display the modality, spatial location and the adjacent relationship of the perforators and vascular net clearly. Conclusion It is feasible to design various cross-boundary perforator flaps in lumbar and gluteal regions.
