The anthropological significance of this anomaly has been the subject of interesting speculation. It may represent an advance towards specialisation of the hand, or it may signify an attempt to stabilise the post-axial border of the hand, in which case it is probably a primitive adaptation which has persisted. This latter is the favoured view. Lunate-triquetral fusion never causes symptoms.
