Findings of the study. (A) Representation of the HFP morphological peculiarities. (B) Spatial relationship between the retrocalcaneal HFP and the achilles tendon insertion. (C) HFP crest is located between the flexor digitorum brevis and the abductor digiti minimi. (D) The unstructured fat area is located on the antero-medial side of the heel, close to the foot arch. (E) HFP thickness is more homogeneously distributed on the posterior rather than on the anterior side. (F) Only slight foot plantarflexion was necessary to leave the heel unloaded during the CT scan.
