OBSOLETE: Hyperphalangy, bilateral

Hyperphalangy, bilateral is an extremely rare skeletal condition in which one or more fingers or toes have extra small bones (called phalanges) in them. Normally, the thumb and big toe have two phalanges each, while the other fingers and toes have three. In this condition, affected digits have more phalanges than expected, and this occurs on both sides of the body (bilateral). It is important to note that this entry is classified as 'OBSOLETE' in the Orphanet database, meaning it may have been reclassified, merged with another condition, or is no longer considered a distinct diagnosis. The extra bones may cause the affected fingers or toes to appear longer or to function differently. In many cases, the condition may be noticed at birth or during childhood when hand or foot X-rays are taken. Because this is an extremely rare and now-obsolete classification, there is very limited information about its specific cause, treatment, or long-term outlook. Patients who have been given this diagnosis should work with a clinical geneticist and an orthopedic specialist to determine whether a more current diagnostic classification applies to their condition. Treatment, when needed, is generally supportive and may include occupational therapy or, in rare cases, surgical correction if the extra bones cause functional problems.
