“…Therefore, it has been suggested that the dorsal branch of the neurovascular bundles should be preserved at these levels (Kojima et al., 1994; Macht and Watson, 1980; Shaw, 1971). More recently, the level of the proximal base of bipedicle flaps has gradually become more distal, and no case of dorsal ischaemia has been reported when the base of the flap is distal to the PIPJ (Chi et al., 2020; Elliot et al., 1995; Furlow, 1984; Kapandji et al., 1991; Loréa et al., 2006; Schuind et al., 1985; Sérane-Fresnel et al., 2020). Moreover, the dorsal branches were not always protected (Elliot et al., 1995; Furlow, 1984; Loréa et al., 2006).…”
