Key Features & Anatomical Relations

The distal phalanx of the middle finger is one of the fourteen phalangeal bones of the hand. It’s classified as a long bone and includes the following bony features:

- parts: head, body, and base;

- landmarks: tuberosity and articular facet.

More information regarding these bony features can be found in the Parts and Landmarks tabs for this bone.

The distal phalanx is located distal to the middle phalanx and articulates with it at the distal interphalangeal joint.


Ossification of the distal phalanx of middle finger occurs at two ossification centers, these are found in the:

- body, which appears in utero during the third month;

- base, which appears during the second to fourth years.

These ossification centers fuse with each other during the fifteenth to eighteenth years (Standring, 2016).
