Posteromediale

Posteromediale, also rendered as posteromedial in English, is a directional term used in anatomy to describe a location that is both posterior (toward the back) and medial (toward the midline) relative to a chosen reference point or plane. It functions as a compound descriptor, conveying two positional dimensions at once, rather than identifying a fixed structure.

The term is employed across medical disciplines to specify where a feature, injury, or incision lies. It is commonly used in descriptions of bones, joints, soft tissues, and neuroanatomical or visceral regions. For example, one might refer to the posteromedial aspect or surface of a bone, the posteromedial corner of a joint, or a posteromedial approach or incision in surgical planning. In radiology and clinical reporting, posteromediale helps localize findings in imaging studies by signaling proximity to both the back and the inner midline of the body.

In practice, posteromediale is defined relative to a standard reference frame, such as the midline of the body and the posterior surface. It is one of several paired directional terms—the counterparts include anterolateral, anteromedial, posterolateral, and other combinations—used to describe precise anatomical positions. The term is applicable to human anatomy and can also appear in veterinary contexts where consistent directional descriptors are needed.

Etymology stems from Latin: posterus (behind, back) and medialis (toward the midline). As with other anatomical descriptors, its exact interpretation can depend on the chosen reference point in a given anatomical study or surgical plan.
