“…Morphology and morphometry of the sacrococcygeal region, including coccyx types, may be linked to various conditions 27,28,31–33,35,38,40–42 . Morphology and morphometry studies have not been linked to PIs, yet the sacrococcygeal area is the most common PI site 20–22 . The exact mechanisms for internal loading and subsequent physiologic responses leading to a PI are not well understood; however, current evidence suggests that damage can result directly from deformation or blood flow impairment by tissue deformation under load 43–46 .…”
