Overlapping toe
Overlapping toes
HP:0001845
What it means
Describes a foot digit resting on the dorsal surface of an adjacent digit when the foot is at rest. Initially clawing may be dynamic and only noticeable on walking. Over time the plantar plate tears, subluxation occurs at the metatarsophalangeal joint (MTPJ), and the deformity becomes permanent.
This descriptor is ordered depending on which toes are involved. The overriding toe is labeled, as specified in the introduction (item 3): e.g., T3,4. The ordering of the numbers specifies which toe is dorsal, i.e., with dorsum of the foot facing upward the toe on top is/are recorded first separated by a comma from the digit that is/are overlapped. Toes that are laterally deviated, but do not rest on top of adjacent toes should be coded as Clinodactyly.

The range is how often this sign appears among people diagnosed with each disease — it is not a probability of having any of them. Many of these signs also occur in common, non-rare conditions. A sign on this page is a conversation to have with a clinician, not a conclusion.
