ACROMION PROCESS Meaning and
Definition
-
The acromion process is an anatomical feature of the scapula or shoulder blade. It is a bony projection that extends from the upper edge or lateral aspect of the scapula, forming the prominent bony tip of the shoulder. The term "acromion" is derived from the Greek word "akros," meaning highest, and "omos," meaning shoulder, which accurately describes its position as the highest part of the shoulder.
The acromion process serves as an attachment site for several important structures, including ligaments, tendons, and muscles. It plays a crucial role in providing stability and support to the shoulder joint, as well as facilitating a wide range of movements of the arm and shoulder.
This bony prominence varies in shape and size among individuals and can be classified into different types based on its morphology. The most common classification system, proposed by Bigliani et al., identifies three types: Type I, flat and relatively horizontal; Type II, curved; and Type III, hooked or elongated.
Knowledge of the acromion process is essential in various medical fields, particularly orthopedics and sports medicine. It is a point of interest in conditions such as shoulder impingement syndrome, rotator cuff injuries, and degenerative changes. Understanding its anatomy and variations assists in the diagnosis, treatment, and surgical management of shoulder-related pathologies.

Etymology of ACROMION PROCESS
The word "acromion" is derived from the Greek words "akros", which means "point" or "topmost", and "omoion", which means "shoulder". Thus, "acromion" can be translated as "the topmost point of the shoulder".
The term "process" is used in anatomy to refer to a prominence or projection on a bone. Therefore, the "acromion process" is the uppermost projection of the scapula (shoulder blade).
