The most likely reason your middle finger is becoming crooked is due to a condition called clinodactyly, often caused by a misshapen bone known as a delta phalanx.
Here's a more detailed explanation:
-
Delta Phalanx: This is an abnormally shaped bone in the finger, often triangular or trapezoidal. This misshapen bone can occur within any phalanx (bone) of the finger, contributing to the bending or curvature.
-
Growth Plate Issues: A delta phalanx may have a curved growth plate or multiple growth plates, leading to uneven growth and causing the finger to bend as you grow. The growth plate is the area of growing tissue near the ends of long bones in children and adolescents.
-
Genetics: Clinodactyly can be hereditary, meaning it can be passed down from parents to their children.
-
Associated Conditions: In some cases, clinodactyly can be associated with other conditions like Down syndrome.
In summary, the crookedness is most likely due to the irregular growth of the bones in your finger, whether it's from the shape of the delta phalanx itself, issues with its growth plate, or an inherited trait. If you are concerned, consult a medical professional for a proper diagnosis and potential treatment options.
