TRAPEZOID RIDGE Meaning and
Definition
-
A trapezoid ridge, also referred to as a trapezoidal ridge, is a distinctive bony prominence located along the middle or posterior region of the sternum, commonly observed in humans. This anatomical structure is formed due to the fusion of the xiphoid process and the sternal body, creating a ridge-like elevation. The trapezoid ridge is named after its shape, resembling that of a trapezoid, with a broad base at the top and narrowing towards the bottom.
The trapezoid ridge represents an important landmark in clinical medicine, particularly in radiology and surgery. It serves as an anatomical reference point for identifying the position of deeper structures within the thoracic cavity. As a result, it aids in surgical procedures such as thoracotomies, where the ridge is used as a guide for making incisions in the chest wall.
Furthermore, the presence, size, and shape of the trapezoid ridge can be subject to natural variations among individuals. Some individuals may exhibit a more prominent ridge, while others may have a less apparent or absent one. These individual differences can be attributed to genetic factors and can serve as valuable anatomical markers in forensic investigations or anthropological studies.
In summary, the trapezoid ridge is a bony prominence formed by the fusion of the xiphoid process and the sternal body. It serves as an anatomical reference point in medical procedures and exhibits interindividual variations.

Etymology of TRAPEZOID RIDGE
The word "trapezoid ridge" can be broken down into two parts: "trapezoid" and "ridge".
- Trapezoid: The term "trapezoid" is derived from the Greek word "trapezion", meaning a little table or a small board. It is a geometrical shape characterized by having a quadrilateral with two parallel sides.
- Ridge: "Ridge" comes from the Old English word "hrycg", which refers to a long, narrow elevation or crest of land. It is related to the Old Norse word "hryggr", meaning "spine" or "backbone".
When these two parts are combined, "trapezoid ridge" refers to a raised or elevated area with a shape similar to a trapezoid.
