It could, rarely, be seen in association with such hand anomalies as the mirror hand, polysyndactyly, and ulnar dimelia. (1-4) Polydactyly is postaxial (the extra ray on the lateral side of the foot) almost 79% of the time and preaxial (15%) when the polydactyly is on the medial (tibial) side of the limb.
Leg anomalies such as tibial hemimelia and fibular dimelia as part of syndromic cases have been reported.
Verghese et al., (1) investigating different foot anomaly patterns in the preaxial mirror foot in association with leg anomalies in 8 cases, reported lateral foot column duplication in fibular dimelia cases and duplication of the talus in tibial-deficient limbs.
Hereditary ulnar and fibular dimelia with peculiar facies.
Las disostosis apendiculares incluyen hemimelia, amelia, dimelia
, polidactilia y ectrodactilia (Towle y Breur, 2012).
Ulnar dimelia, is an exceedingly rare congenital anomaly of the upper limb.
Although less than 100 cases have been reported in the literature, many variants of ulnar dimelia have been described.
