Normal and five-fingered hand: comparative X-ray morphometry in the post-natal age.

CONCLUSIONS: The relative length and IGR comparative analysis in the two groups suggested homology of the (anatomical) 1st metacarpal with the 2nd - 5th proximal phalanges in the same hand and that of the (anatomical) 1st proximal phalanx with the 2nd-5th mid phalanges. These data suggest that the missing segment of the thumb normal hand is the metacarpal. PMID: 32644183 [PubMed - as supplied by publisher]
