Olkapäästä

Olkapäästä is a term referring to the shoulder in Finnish. The human shoulder is a complex ball-and-socket joint connecting the upper limb to the trunk. It is comprised of three bones: the clavicle (collarbone), the scapula (shoulder blade), and the humerus (upper arm bone). These bones are united by a network of muscles, ligaments, and tendons, which allow for a wide range of motion.

The shoulder joint's articulation is facilitated by the glenohumeral joint, where the head of the humerus fits into the glenoid cavity of the scapula. This arrangement provides exceptional mobility, enabling movements such as flexion, extension, abduction, adduction, rotation, and circumduction. However, this extensive range of motion also makes the shoulder susceptible to injuries like dislocations, sprains, and rotator cuff tears.

Rehabilitation and physical therapy are often crucial in recovering from shoulder injuries, aiming to restore strength, flexibility, and pain-free movement. Understanding the anatomy and biomechanics of the shoulder is essential for athletes, healthcare professionals, and individuals seeking to maintain or improve their shoulder health.
