Sports Injuries: Kin 3K03 GLENOHUMERAL INSTABILITY (GHI) GH Joint Stabilizers • PASSIVE o Things that hold the joint together: joint capsule, ligaments (reinforce the capsule; mostly anterior and inferior aspects of joint), labrum (functions as suction cup to hold joint together), negative intrajoint pressure (suction mechanism brings 2 bones together) • DYNAMIC o SITS muscles responsible for holding humeral head to glenoid fossa (supraspinatus, infraspinatus, teres minor, subscapularis) What Is Instability? - Instability leads to subluxation and complete dislocation • TUBS o Trauma; unstable shoulder related to trauma o Unidirectional instability; injured in one direction o Bankart lesion; detachment of labrum off glenoid o Surgery; required • AMBRI o Atraumatic; minor trauma o Multidirectional instability; more than one direction o Bilateral; not specific to one shoulder. AMBRI people have generally loose shoulders from birth. o Rehabilitation; treatment of choice o Inferior capsular shift; preferred surgery • FEDS Kuhn o Frequency; how often do they experience instability? o Etiology; how did it happen? trauma or no o Direction; which way is the dislocation? o Severity; did the shoulder go back in on its own or did you need assistance? Traumatic Anterior Dislocation • Common mechanism: abduction (close to 90 deg.), lateral rotation, axial (traumatic) load to the shoulder from behind pushing it forward. Recognition • Appearance: prominence of humeral head (with someone with less muscle), deltoid contour - you will see: bulge in armpit, fossa, acromion, but not deltoid. Patient will be holding their arm close to their body. • Symptoms: PAIN (lots of it) • Axillary nerve damage? Armpit nerve, sensory and motor disruption with anterior dislocation. Where will they have sensory disruption and what muscles will be affected? (independent study) o Deltoid will be affected and sensory loss will occur below the shoulder around deltoid Labral Tears - Bankart Lesion:detachment of glenoid labrum from glenoid (80% of people who have their first dislocations will have this). When a labrum/lip is damaged, you will have dislocations frequently. - SLAP Lesion: superior labrum from anterior to posterior. T
