The scapula, commonly known as the shoulder blade, is a crucial bone in the human body that plays a pivotal role in shoulder mobility and stability. This flat, triangular bone connects the upper arm to the torso, facilitating a wide range of movements while providing structural support to the shoulder girdle. Understanding its anatomical structure is essential for professionals in fields like orthopedics, physical therapy, and sports medicine. This article explores the detailed anatomy of the scapula, highlighting its key features from both anterior and posterior perspectives, as well as its physical significance in human movement and stability.

The scapula, a flat triangular bone in the shoulder girdle, is crucial for upper limb mobility and stability, but its anatomical features can challenge medical students. The mnemonic “SSS for Borders” provides a concise and memorable way to recall the three borders of the scapula, simplifying this key anatomical topic. This tool aids students in mastering shoulder anatomy for exams and enhances clinical understanding, particularly in diagnosing shoulder injuries or planning orthopedic interventions.
