An arch worth revisiting: a study on the feline humeral supracondylar foramen and its evolutionary significance.

ABSTRACT: The supracondylar foramen with a (seemingly) osseous peripheral arch noticed on the medio-distal feline humeri had remained disputed among anatomists. Some scholars have argued in favor of homology between this foramen and the supracondyloid foramen formed in presence of the ligament of Struthers in humans. Other theories include its presence as a retinaculum holding the median nerve and brachial artery to their anatomical position in a flexed elbow. Unfortunately, these theories lack investigative rigor. The emergence of non-invasive imaging modalities, such as micro-computed tomography, has enabled researchers to inspect the internal anatomy of bones without dismantling them. Thus, a micro-computed tomographic investigation was conducted on three feline (Felis catus) humeri specimens whi
