Abstract:
Objective To provide guidance for reconstructing the sensation of the anterolateral thigh flap (ALTF) used to repair extensive soft tissue defects in heel. Methods Choose 7 adult male corpses, take the nerval samples respectively from the lateral femoral cutaneous nerve (LFCN) 5cm below the anterior superior iliac spine (ASIS) and the initial segment of the medial caleaneal nerve (MCN) and the lateral calcaneal nerve (LCN), fixed, dewatered gradiendy, embedded, located, and made them into semithin sections, dyed with toluidine blue. The pictures were taken by a medicine figure imaging analysis system named MOTICMED 6.0, observe the nerves's sectional morphous, the quantity and distribution of their nerve fiber bundles, count the quantity of nerve fibers and determine the density of them. Use Photoshop 7.0 version precinct software for measuring and calculating the area of the nerve fiber bundles and the Photoshop grid function was used to measure the density of the nerve fibers. Results In our cross-section study, the median number of nerve bunches in LFCN, MCN and LCN1, was 4, 3 and 4, respectively. The median number of nerve fibers' area was 114.8 um2, 126.92 um2 and 102.76um2, respectively. The median number of nerve fibers' density was 11.43/um2, 6.47/um2 and 10.08/um2, respectively. The median number of nerve fibers was 987, 862 and 570, respectively. Conclusion The MCN and the LCN1 are ideal cutaneous nerves to suture with LFCN in the ALTF used to repair widespread soft tissue defects in heel because they have similar histomorphological characteristics with the LFCN.
