Essay On Scapular Dyskinesia
Introduction
Scapular dyskinesia is close to me due to its relation with my family. My brother has scapular dyskinesis due to his athletic endeavors in swimming and possibly due to some genetic factors that run in our family. This abnormal scapulohumeral rhythm is seen in shoulder instability, at a rate of 67%, and in shoulder impingement, at a rate of 100%. Shoulder injuries tend to be prevalent at a high rate in today’s population due to impact sports, accidents, and ever increasing elderly population. Although seen very frequently in shoulder instability and impingement, there are no statistics on the incidence of this condition as a whole.
Anatomy Overview Scapular dyskinesis is an anatomical dysfunction of the scapula, or more commonly known as the shoulder blade. The scapula is a bone that connects the humerus and the clavicle to the axial skeleton with its muscle attachments and provides stabilization to the arm. The scapula is a triangle bone; relatively flat in shape that forms the shoulder girdle. The scapula has multiple surfaces where muscles originate and attach. These surfaces are the subscapular fossa (costal side), infraspinatus fossa, and supraspinatus fossa (both dorsal side). There is also the scapular spine, glenoid fossa, acromion, and the superior, medial, and lateral borders. The glenoid …show more content…
There are two main joints that the clavicle attaches to: the sternoclavicular joint and the acromioclavicular joint. The SC joint is extremely stable and does not encounter problems except for extreme trauma. The AC joint however, is much more loose in its structure and thus is more susceptible to injury. Focusing more on the AC joint, it is made up of three ligaments: acromioclavicular, coracoclavicular, and coracoacromial ligaments. These help stabilize the shoulder and scapula to keep the scapula tracking
