“…To the authors’ knowledge, this is the first reported case where MRI and ultrasound have been used to better understand an equine supernumerary digit excision and the first case where the long‐term outcome (8 years) is provided. Polydactyly is usually easily diagnosed by clinical examination and definitive diagnosis is made with radiographs (Ahmed ). Polydactyly can be associated with abnormalities in the carpal bones (Barber ); therefore, radiographs should include the metacarpus II, metacarpus IV and the carpus.…”

“…Polydactyly is commonly reported in domestic species, including dogs (Paryani, 2015), ruminants (Al-Ani, Hailat, & Fathalla, 1997), horses (Carstanjen, Abitbol, & Desbois, 2007;Stanek & Hantak, 1986), and camels (Ahmed, 2014). Considerable diversity in polydactylous phenotypes has been described in cats (Danforth, 1947;Hamelin, Begon, Conchou, Fusellier, & Abitbol, 2017;Lettice, Hill, Devenney, & Hill, 2008).…”

Polydactyly is a congenital malformation resulting from an autosomal dominant mutation manifesting as supernumerary digits of the hands or feet. It is most commonly reported in humans and domestic mammals, though there have also been isolated examples across a range of wild vertebrate species.Here we report a case of extremely unusual bilateral preaxial polydactyly on the pectoral limbs of a male western grey kangaroo (Macropus fuliginosus) from the South West region of Western Australia, in which two supernumerary digits were present on each manus. A supernumerary digit I on each manus was rudimentary in morphology without extrinsic muscular connections. However, supernumerary digit II present on each manus had fully developed extrinsic and intrinsic muscular connections, suggesting that these digits possessed normal function in flexion and extension. An alternative hypothesis is that the two supernumerary digits are both representatives of the most radial digit I, though this would then require the true digit I to have taken on the appearance of digit II by acquiring an additional phalanx and modified muscular attachments. The carpal bones exhibited a number of subtle differences in morphology when compared to normal pentadactyl individuals. The presence of a distal, rather than proximal, epiphysis on the first metacarpal was unexpected but further investigation suggested that this characteristic is perhaps more variable (in this species at least) than has been previously recognized.This case provides an unusual example to be considered within the broader context of limb development.

“…Palec dodatkowy najczęściej występuje po przyśrodkowej stronie kończyny piersiowej, ale zdarzają się również przypadki deformacji po stronie bocznej lub po obydwu stronach kończyny. Może pojawić się w jednej, w dwóch albo we wszystkich czterech kończynach (1,7).…”

The article describes the case of a 6-month-old Hucul mare with an additional second finger of the right thoracic limb. The surgery to eliminate the deformity was planned on the basis of the clinical picture and the results of radiological examination. The additional finger was removed along with a fragment of the second metacarpal bone. The postoperative management and rehabilitation went well. The horse showed no lameness in the follow-up examination. The outline of the phalango-metacarpal joint of the operated limb was slightly enlarged. There was also a minor deformity in the palmar area of the third metacarpal bone. The procedure of a complete amputation of the additional finger with a fragment of the second metacarpal bone made it possible to use the horse later and produced a satisfactory cosmetic effect.
