Pectus carinatum is an overgrowth of costal cartilage, causing the sternum to protrude forward. It primarily occurs among four patient groups, and males are more frequently affected than females. It primarily occurs among four patient groups, and males are more frequently affected than females.

Throughout this movement the scapula is rotated around the chest wall so that it moves 15 centimetres (5.9 in) laterally and the glenoid cavity is rotated 40–45° in the horizontal plane.
The clavicle, collarbone, or keybone is a slender, S-shaped long bone approximately 6 inches (15 cm) long [1] that serves as a strut between the shoulder blade and the sternum (breastbone). There are two clavicles, one on each side of the body.

Fourthly the pectoralis major is also responsible for keeping the arm attached to the trunk of the body. [7] [8] It has two different parts which are responsible for different actions.
The cross-arm adduction will produce pain specifically at the AC joint and will be done by elevating the arm to a 90° angle, flexing the elbow to a 90° angle, and adducting the arm across the chest.
