Polyphalangism is a medical condition where an individual has extra phalanges or digits on their hands or feet. The word is spelled as "pah-lee-fuh-lan-jiz-uhm" (/ˌpɑliˈfəlæŋɪzəm/) in IPA phonetic transcription. The prefix "poly" means multiple or many, "phalanx" refers to the bones in the fingers or toes, and the suffix "-ism" indicates a condition or state. Therefore, polyphalangism means having multiple phalanges or fingers/toes on a single hand or foot. This condition can be genetic or result from fetal limb abnormalities.
Polyphalangism is a medical condition characterized by the presence of extra fingers or toes, resulting from the abnormal development of phalanges in the skeletal system. It is a congenital anomaly often identified at or shortly after birth. The prefix "poly-" denotes the existence of many, and "phalangism" refers to the abnormality in the phalanges, which are the small bones that make up the fingers and toes.
Individuals affected by polyphalangism may have additional digits located adjacent to the normal fingers or toes. These extra digits may vary in size, appearance, and functionality. In some cases, the additional digits may be fully formed and possess joints, nails, and even muscles, allowing for limited movement. Conversely, they can also manifest as non-functional appendages that lack proper development.
Polyphalangism can occur as an isolated anomaly or in association with other genetic disorders or syndromes. The condition is caused by genetic mutations or disruptions during embryonic development, which affect the formation and division of the digits.
Treatment for polyphalangism often involves surgical intervention, which aims to remove or correct the additional fingers or toes. The decision to surgically address the condition depends on the functionality of the extra digits, their impact on daily activities, and the overall health of the individual. Surgical procedures may include removal of the excess digits or a combination of procedures to reposition or reconstruct the existing digits.
In conclusion, polyphalangism is a medical condition characterized by the presence of additional fingers or toes, resulting from abnormal development of the phalanges. It can vary in severity and treatment typically involves surgery to address the extra digits and improve functionality.
Hyperphalangism; the presence of a supernumerary phalanx in a finger or toe.

The word "polyphalangism" is derived from two roots: "poly" and "phalanx", combined with the suffix "-ism".
1. "Poly": It comes from the Greek word "polýs", meaning "many" or "multiple". This prefix is commonly used in English to indicate "more than one" or "many".
2. "Phalanx": This term originated from the Greek word "phálanx", referring to a closely arranged military formation or a row of soldiers. In anatomy, a phalanx is a bone in the finger or toe.
3. "-ism": The suffix "-ism" is used to form nouns that denote a state, condition, or practice. In this case, "polyphalangism" means the state, condition, or presence of having multiple phalanges.
