“…As commented earlier, different facet configurations had been observed in the second and third trimesters of unborn fetuses (Bunning & Barnett, 1965; Rehman, 2014) pointing to an important genetic influence. Some studies have suggested that the talo‐calcaneal facet frequencies, which have been shown to differ between various populations, are sufficient evidence to state that the talo‐calcaneal joint morphology is strongly affected by genes (Garg et al, 2013; Nagar et al, 2012; Parimala & Reddy, 2016; Vučinić et al, 2020). For example, data from some European and North African samples show a predominance of three facets (Bunning & Barnett, 1965; Saadeh et al, 2000), but other European samples have shown a predominance of two facets (Forriol Campos & Gomez Pellico, 1989; Gupta et al, 1977; Uygur et al, 2009).…”
