Short palm

Page most recently updated 7 September 2026

This page focuses on short palm as a morphologic feature of conditions that may also be associated with psychiatric manifestations, such as psychosis, mania, autism spectrum disorder, ADHD, OCD, and self-injurious behaviours. The page begins with a clinical definition of short palm based on the standardized Elements of Morphology terminology, together with visual examples from the same source. This is followed by a list of conditions in which short palm has been described in association with psychiatric manifestations.

Of note, to optimize clinical utility, the list does not include conditions associated with intellectual disability in the absence of other psychiatric features.

Each condition listed below is linked to a dedicated page within this resource. These pages describe the psychiatric manifestations associated with each condition, as well as other morphologic and broader clinical features, allowing the differential diagnosis to be considered from multiple perspectives.

Definition

Subjective: The length of the palm appears relatively small compared to the finger length or the limb length.

Objective: For children from birth to 16 years of age the length of the palm is less than the 3rd centile.

Note: Palm length is measured as described in (refs). This term is reserved for individuals with shortening of all four metacarpals 2–5. Individuals with fewer than four shortened metacarpals (in a eudactylous hand, the metacarpals of F2–5) should be described as Short metacarpal. See the entry for Small hand for a discussion of this finding. Short hand should not be used as it is a bundle of two readily separable terms, Short fingers (which, as noted above, can itself be a bundled term) and Short palm.

Replaces: Short hand.
