Lint: frantz-and-orahilly-classification

"This classification divides limb deficiencies into two major categories, terminal and intercalary, each with transverse and longitudinal subcategories."

"partial aphalangia: absence of one or more phalanges from one to four digits: 1, 2, 3, 4 or 5"

"complete paraxial hemimelia: similar to corresponding terminal defect, but the hand or foot is more or less complete – R, U, T or FI"

"incomplete paraxial hemimelia: similar to corresponding terminal defect, hand or foot is more or less complete – r, u, t, fi"

"In 1961, Frantz and O’Rahilly published a classification system to standardise the nomenclature of limb deficiencies, which by then had many confusing terminologies for similar pathologies. For example, to describe partial adactylia, there were around ten different synonyms, which confused orthopaedic surgeons. To curb this, the new classification was published and subsequently revised ^1,2."

"complete paraxial hemimelia: complete absence of one of the forearm or leg elements and of the corresponding portion of the hand or foot. The absent element could be either radius (R), ulna (U), tibia (T), or fibula (FI)"

"incomplete paraxial hemimelia: similar to complete paraxial hemimelia but part of the defective element is present. The absent element could be either radius (r), ulna (u), tibia (t), or fibula (fi)"

"partial adactylia: absence of one or four digits and their metacarpals or metatarsals; the digits are numbered as 1, 2, 3, 4, or 5."
