“…Terminal transverse limb defects (TTDs) of the forearm are reported to have an overall incidence of 1 per 25,000 live births [Birch-Jensen, 19491. These defects are usually sporadic [Czeizel et al, 1983;Hoyme et al, 1982;Nevin et al, 1975;Robinow et al, 19781 but have also occurred in some families perhaps due to a dominant trait [Bartoshesky et al, 1986;Graham et al, 1986;Hecht and Scott, 1981a;Soltan and Holmes, 19861. Autosomal recessive inheritance has also been suggested [Hecht and Scott, 1981bl and Brazilian families have been described with recessively inherited TTD of all limbs termed acheiropodia [E'reire-Maia, 19751. Some families inherit defects of the scalp and skull in conjunction with TDD (the Adams-Oliver Syndrome) [Bonafede et al, 1979;Kuster et al, 1988;Scribanu et al, 19751. Multiple pathogeneses of TTD have been proposed including amniotic band disruption sequence and vascular disruption [Bartoshesky et al, 1986;Bouwes Bavinck and Weaver, 1986;Bokesoy et al, 1983;Bouvet et al, 1978;Higginbottom et al, 1979;Hoyme et al, 1982;Soltan et al, 19861. In some instances vascular disruption has been attributed to intrauterine ischemia and secondary necrosis [Webster et al, 19871.…”
