Shoulder Injuries
Unit 5 Essential Question: What are common athletic injuries to the shoulder and how do they occur?
To do this you will need to be be able to answer the following:
1. Discuss the shoulder girdle complex to include the structure and scapulthoracic mechanics.
2. Identify the shoulder girdle anatomy: boney markings, brachial plexus...
Why is it important for me to learn about injuries to the shoulder? Below the state of South Carolina feels that you should know the following information:
SC State Standard:
1:3 Identify major bones in the body.
1:5 Describe general injury causation and/or mechanisms.

Scapula Bone Interactive Tutorial
Click on the first link to the right. This is an interactive tutorial over the anterior scapula. This will be important to know as we progress into learning the muscles of the rotator cuff. Read the information that you see to the right of the picture. Click on the blue titles for the picture to become labeled. As you identify each boney landmark on the anterior scapula, highlight it on your coloring page, "Pectoral Girlde and Arm Bone." When you can identify the structures, and have read the information continue to the next tutorial.
Click on the second link to the right. This is an interactive tutorial over the posterior scapula. This will be important to know as we progress into learning the muscles of the rotator cuff. Read the information that you see to the right of the picture. Click on the blue titles for the picture to become labeled. As you identify each boney landmark on the posterior scapula, highlight it on your coloring page, "Pectoral Girlde and Arm Bone." When you can identify the structures, and have read the information continue to the next tutorial. Click on the third link to the right. Using the coloring page, "Pectoral Girdle and Arm Bone" identify each of the boney landmarks on the anterior scapula practice quiz. Click on the fourth link to the right. Using the coloring page, "Pectoral Girdle and Arm Bone" identify each of the boney landmarks on the posterior scapula practice quiz. |

Lecture 2: Brachial Plexus
|
|
The Brachial Plexus innervates the nerves of the shoulder. These nerves branch off of the spinal column through foramen (openings) at the fifth cervical vertebrae (C5) through the first thoracic vertebrae (T1). We refer to the point where they branch off as the "root." As they branch they weaves their way through the shoulder all the way down the arm.

Lecture 3: Rotator Cuff Muscles
|
|
|
|
Above - Subscapularis, the only RC muscle on the anterior aspect of the body.
Below - Infraspinatus |
Above - Supraspinatus, runs through the tunnel created by the glenoid fossa, acromian (hook off of the posterior scapula), coracoid (hook off of the anterior scapula), and AC ligament
Below - Teres Major |

Lecture 4: RC and Brachial Plexus Injuries
|
|
RC AnimationSurgical Repair |
Arthroscopic RC Repair |
There are four muscles of the Rotator Cuff:
- Supraspinatus - contraction results in abduction. It is the most frequently strained of the four cuff muscles. It is also involved in Impingement Syndrome by repetitive overhead activities. It's origin is the medial spine of the scapula, through the tunnel of the acromian, and inserts on the humeral head.
- Infraspinatus - contraction results in external rotation (noted as lateral rotation on your GH Joint coloring sheets). It's origin is the medial spine of the scapula, under the scapula ridge to the head of the humerus.
- Teres Minor - contract results in external rotation (noted as lateral rotation on your GH Joint coloring sheets). It's origin is the lateral border of the scapula and inserts on the head of the humerus.
- Subscapularis - contraction results in internal rotation (noted as medial rotation on your GH Joint coloring sheet). It's origin is the medial spine of the scapula and inserts of the head of the humerus. It is the only rotator cuff muscle that is on the anterior side of the scapula (meaning it runs between the ribs and scapula so you would have to pick the shoulder blade up and look underneath it to see the muscle).

Class Assignment - 20 points of participation grade
Add to your Upper Extremity Quizlet set that you have already created with shoulder terms. Create a card for each of the following terms, your card must include detailed information and cannot contain the term itself. If it is an injury before to include the MOI, s/s, tx, and special tests if given. If it is an anatomical structure be sure to include it's origin and insertion, as well as its directional term. Finally, make sure to include a picture with your information when instructed to do so. Turn in the link to your quizlet set on Google Classroom assignment by the end of class today. This should give your set approximately 80 cards.
