Posterolaterale

Posterolaterale is a directional term used in anatomy to describe a location that is both posterior (toward the back) and lateral (toward the outer side) relative to a defined reference point or body plane. In English-language anatomy the equivalent term is posterolateral; posterolaterale may appear as a declined form in languages that inflect adjectives, such as German, where it can modify a feminine or neuter noun.

In clinical and descriptive anatomy, posterolateral describes surfaces, regions, and structures situated at the back and outer side of a body part. Common examples include the posterolateral aspect of the knee, hip, shoulder, or skull base. Descriptions using posterolateral help convey the precise spatial relationships needed for imaging, surgery, and rehabilitation.

A notable application is the posterolateral corner of the knee, a region at the back and outer aspect of the knee where several ligaments and tendinous structures contribute to joint stability. Injury or pathology in this area can affect knee stability, including resistance to varus stress and control of external rotation.

The term is closely related to other directional descriptors such as posteromedial, anterolateral, and anteromedial, and is used across human and veterinary anatomy to specify relative position.
