Key Features & Anatomical Relations

The proximal phalanx of the ring 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: proximal and distal articular facets.

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

The proximal phalanx is located:

- proximal to the middle phalanx of the ring finger;

- distal to the fourth metacarpal bone;

It articulates with the:

- middle phalanx at the proximal interphalangeal joint;

- metacarpal bone at the metacarpophalangeal joint.

Ossification

Ossification of the proximal phalanx of ring 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 year.

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

Surface Anatomy

The head, body, and base of the proximal phalanx can be easily palpated.
