This detailed overview focuses on the anatomy and soft tissue structures of the shoulder, including bony anatomy such as the clavicle, scapula, and humerus. Key muscles, including the pectoralis major, deltoids, and rotator cuff (SITs: supraspinatus, infraspinatus, teres minor, and subscapularis), are examined. We discuss range of motion for flexion, extension, abduction, and rotation, as well as custom bracing techniques like the Sully Brace and shoulder spica taping for injuries. Perfect resource for healthcare professionals and athletes alike.

Bony Anatomy • Clavicle • “Collar Bone” • Only part of shoulder girdle that articulates with the trunk (Sternoclavicular Jt.) • Scapula • “Shoulder Blade” • Humerus • Upper Arm Bone • Articulates with the Scapula at the Glenoid Fossa
Soft Tissue Anatomy: Muscles • Pectoralis Major • Deltoids (Anterior, Middle, Posterior) • Latissimus Dorsi • Teres Major
Rotator Cuff Muscles • Rotator Cuff • Supraspinatus • Infraspinatus • Teres Minor • Subscapularis
Soft Tissue Anatomy: Ligaments • Acromioclavicular • Connects Acromion Process to the Clavicle • Coracoclavicular • Connects Coracoid Process to the Clavicle • Coracoacromial • Connects Coracoid Process to the Acromion
Range of Motion • Flexion • Pec. Major (Clavicular Portion)/Ant. Deltoid • Extension • Latissimus Dorsi/Teres Major/Pec Major (Sternal Portion) • Abduction • Deltoids and Rotor Cuff • Adduction • Pec. Major (Sternal Portion)/Lat. Dorsi/Teres Major
Range of Motion Con’t • External Rotation • Supraspinatus/Infraspinatus/Teres Minor • Also known as the “SIT’s” muscles of the Rotator Cuff • Internal Rotation • Subscapularis and Pec. Major • Horizontal Abduction • Infraspinatus, Teres Minor, and Post. Deltoid • Horizontal Adduction • Coracobrachialis, Pec. Major, Ant. Deltoid • Circumduction
Padding • AC Joint Pad • Can be custom made using Orthoplast • Can be generic
Bracing • “Sully” Brace
Shoulder Wrap • Shoulder Spica • Have athlete place their hand on their hip with the elbow in a flexed position. • Beginning on Proximal Humerus, roll wrap twice to anchor. • Pulling wrap across the chest, crossing the shoulder at the Acromion process. • Pull wrap under opposite axilla region (armpit) and around behind the back crossing over the Acromion process, underneath the axilla and around crossing back over the Acromion. • Repeat steps until wrap is completed. Secure with stretch and white tape.
Taping • McConnel taping for AC Jt. Sprain • Use Cover-Roll to form a “T” shape with the long axis following the length of the humerus to the deltoid tuberosity. The short axis crosses the top of the long axis over the AC Jt. • Using Leukotape place along the long axis pulling in a distal to proximal manner. Place another strip on the anterior aspect of the short axis pulling from anterior to posterior across the AC Jt.
