Scapula : scapula is triangular shape has three border superior and medial and lateral ,three angle inferior,superior and lateral and three surface. Sternum : sternum consist of manubirum where SC joint attached ,body where ribs attached and xiphoid process. On the inferiolateral surface is costal tuberosity attachment for costoclavicular ligament. the rounded medial sternal end articulate with sternum to form sternoclavicular joint while the other flat end articulate with acromion to form acromioclavicular joint. clavicle deviated 20 degree with frontal plane in anatomic position. medial two third give attachment to pectoralis major muscle. weakness of any muscle change normal kinematic chain of the joint.Ĭlavicle : clavicle is long bone has convex medial two third and concave lateral one third. Muscles of the shoulder work in team to produce highly coordinated motion. To effectively rehabilitate a shoulder injury in clinical practice, it is important to have a functional knowledge of the underlying biomechanics of the shoulder complex. Due to the multiple joints involved during shoulder movement, it is prudent to refer to the area of the shoulder complex.
The shoulder area is infamously known to be one of the most complex regions of the body to evaluate and rehabilitate. 5 Static Structures and Mechanoreceptors.
