However, considering that this rumour first emerged in the 1580s from a Catholic dissenter, it is generally deemed false. Robert Chambers, purported author of Vestiges of the Natural History of Creation, and his brother William had six digits on each limb. Lucille Clifton, an African-American poet and civil rights advocate. Zerah Colburn, American prodigious math calculating savant. Calvin Choy, a Hong Konger singer and actor nicknamed "Sir One One" (Sir11) as he has six digits on his right hand. Several members of a Da Silva family in São Paulo, Brazil, have two thumbs on each hand. Vicente Fox, former President of Mexico, has six toes on each foot. Danny Garcia, boxing champion, has six toes on his right foot. Yoandri Hernández Garrido, nicknamed "Veinticuatro" ("twenty four" in Spanish), has six fully formed fingers on both hands and six perfect toes on each foot. Hampton Hawes, jazz pianist, was born with six fingers on each hand (the extra fingers were surgically removed shortly after birth). Henry II the Pious, High Duke of Poland 1238–1241, had six toes on his left foot. A boy named Hong Hong born in Pingjiang County, Hunan province, China, has 31 fingers and toes. Kamani Hubbard, a boy in California was born in 2009 with a rare case of polydactyly, with 12 fingers and 12 toes, all fully functional. Johann Jacob Freiherr von Moscon (1621–1661), Lower Styrian baron, is depicted with six fingers at his left hand on a portrait from Brežice, Slovenia.
Treatment
Ulnar polydactyly
Ulnar polydactyly usually does not interfere with hand function, but for social reasons it can be treated operatively. Type A ulnar polydactyly
The treatment of Type A ulnar polydactyly is complex as its goal is to remove the accessory digit while maintaining a stable, functional small finger. When the duplicated proximal phalanx articulates with a common, broad metacarpal head, the ulnar collateral ligament must be considered. In those cases with a common articulation or with a sixth metacarpal the muscle executing the abduction of the little finger (abductor digiti minimi) must be preserved. In patients with a common metacarpal articulation an elliptical incision at the base of the post-axial digit is made. This incision may be extended proximally in order to adequately expose the abductor digiti minimi. The ulnar collateral ligament and the insertions of the abductor digiti minimi are then elevated with a periosteal sleeve. The duplicated extensor and flexor tendons to the ulnar digit are transected and after that the digit is amputated at its articulation with the metacarpal. If the articular surface is wide the metacarpal may be shaved. At last the collateral ligament and abductor digiti minimi are reinserted at the base of the preserved proximal phalanx and a wire is then placed across the reconstructed joint. In patients with a duplicated metacarpal, the accessory digit is amputated in a standard ray fashion with transfer of the abductor digiti minimi to the retained small finger. Type B ulnar polydactyly
In this situation there is an absence of osseous and ligamentous structures.
