Types of Impingement Force Source Primary subacromial impingement • Irregularly shaped acromion • Spur formation on acromion • Os acromiale Secondary subacromial impingement • Loss of humeral head depression or stabilization • Poor posture • Repetitive overhead movement • Scapular dyskinesis • GH instability • Supraspinatus hypertrophy Internal impingement • Glenohumeral internal rotation deficit (GIRD) • GH instability • High volume of throwing or other repetitive overhead activity • Occupation requiring repetitive overhead activity Copyright © 2015.

Pathologies of the Shoulder and Related Special Tests § Biceps tendon pathology § Bicipital tendinopathy § Causes § RTC dysfunction § Impingement § Superior labrum anterior to posterior lesions (SLAP lesions) § Tears of the superior aspect of the glenoid labrum that extend anteriorly and posteriorly to the biceps insertion Copyright © 2015. F. A. Davis Company
Classification of SLAP Lesions Type Pathology I Degenerative fraying of the labrum near the insertion of the LHBT II Avulsion of the glenoid labrum with an associated tear of the LHBT Type II SLAP lesions have been further classified relative to the detachment of the labrum: • Isolated to the anterior aspect • Isolated to the posterior aspect • Appearing in both aspects III A bucket-handle tear of the labrum with displacement of the fragment; no involvement of the LHBT IV Bucket-handle tear of the labrum with associated tearing of the LHBT = long head of the biceps tendon; SLAP = superior labrum anterior to posterior Copyright © 2015.

F. A. Davis Company Position of the humeral head AC joint alignment Clavicle Sternoclavicular joint Humerus
Initial Management of On-Field Shoulder Injuries § Scapular fracture § § Body of the scapula Glenoid fossa Glenoid neck Coracoid process § Management § Immobilize the arm on the affected side in a comfortable position § Athlete then is transported. § GH dislocation also needs a radiographic evaluation to rule out a secondary fracture to the glenoid or coracoid process. Copyright © 2015. F. A. Davis Company
On-Field Examination of Shoulder Injuries § Clavicular injuries § Clavicular fracture § Immobilization using a sling or triangular bandage § Transport for definitive diagnosis Copyright © 2015. F. A. Davis Company
On-Field Examination of Shoulder Injuries § Sternoclavicular joint injuries § Neurological and vascular examination of the extremity and carotid artery § Involved arm is immobilized. § Athlete is immediately transported to an emergency medical facility. Copyright © 2015. F. A. Davis Company
On-Field Examination of Shoulder Injuries § Acromioclavicular joint injuries § Immobilize in a position that lessens the displacement between the clavicle and the acromial process § Protect joint with additional padding during activity Copyright © 2015. F. A. Davis Company
On-Field Examination of Shoulder Injuries § Glenohumeral dislocations § Monitor the distal pulses, check for circulation in the fingertips, and perform a sensory screen § Arm is fixed in the position it has assumed. § Reductions of GH dislocations should only be performed by those who are trained to do so. Copyright © 2015. F. A. Davis Company
On-Field Examination of Shoulder Injuries § Glenohumeral dislocations (cont. ) § Forced reduction of the humeral head may damage the glenoid fossa, the coracoid process, or the neurovascular structures in the area. Following reduction, assess distal pulse and active range of motion, avoiding external rotation and abduction. Stabilize the shoulder using a sling, and refer the athlete for further examination.

On-Field Examination of Shoulder Injuries § Humeral fractures § Splint in position found using moldable splint or vacuum splint § Leave wrist and fingers exposed to check circulation § Transport Copyright © 2015. F. A. Davis Company
