The middle phalanges (also known as intermediate phalanges, Latin: (pl.) Anatomy. It articulates with the distal phalanx through a high-motion joint and proximally with the proximal phalanx through a relatively low-motion joint. Middle phalanx fractures are the least common of the phalanx fractures. The base of the middle phalanx has a dorsal and volar lip. Ultrasonography can be used in unclear cases. A middle phalanx is present in each digit foot (or hand) except for the first digit - the big toe of the foot (also the thumb of the hand), which lacks a middle phalanx. The middle phalanges (also known as intermediate phalanges, latin: (pl.) Middle phalanx - Phalanx media Anatomical Parts. Radiographic features These fractures are generally well visualized on plain radiographs. So, the middle phalanges are exactly what they sound like: phalanx bones that are in the middle of the foot. The intermediate phalanx is not only intermediate in location, but usually also in size. Anatomy of special importance to middle phalanx fractures is described below; a more detailed discussion of finger anatomy is found elsewhere. Anatomical hierarchy. Illustrated anatomical parts with images from e-Anatomy and descriptions of anatomical structures . phalanx media) lie between the proximal and distal phalanges. The distal phalanges are the bones at the tips of the fingers or toes. The thumb and large toe do not possess a middle phalanx. The proximal, intermediate, and distal phalanges articulate with one another through interphalangeal articulations. There are four middle phalanges which correspond to the index finger, the middle finger, the ring finger and the little finger. The proximal interphalangeal (PIP) joint and the distal interphalangeal (DIP) joint form the articulations of the middle phalanx ( figure 1 and figure 2 ). Middle phalanges. (See "Finger and thumb anatomy" .) The middle phalanx is a relatively compact bone that is loaded predominantly in axial and torsional planes during athletic activity. phalanges mediae, (sg.) The middle phalanges (foot) bones of … Related Anatomy. phalanges mediae, (sg.) They have a proximal base and a distal head which is separated by a much shorter shaft than that of the proximal phalanges. The middle phalanx consists of a distal phalangeal head that articulates at the distal interphalangeal (DIP) joint with the distal phalanx, a narrow diaphyseal shaft, a proximal metaphysis, and a base that articulates at the PIP joint with the proximal phalanx.
