Shoulder Injuries

The reason impingement syndrome is so painful is because

• there is a tear in the bicep tendon
• the suprasinatus and bicep tendons are pinched under the acromion
• there is a shoulder separation of the AC joint
• there is a rotator cuff strain

If a person says they have a rotator cuff strain it means there is a strain in the

• muscles
• ligaments 
• tendons
• all of these

Strains in the rotator cuff are most often caused by

• blunt force trauma
• muscle weakness
• internal rotation
• excessive motion beyond normal range of motion

An avulsion fracture is most likely to occur

• when a joint is dislocated

• along with a 1st degree strain

• if a dislocation subluxates

• all of these

A shoulder separation occurs when

• the rotator cuff is strained
• when the AC joint is pulled apart
• the humeral head is dislocated from the socket
• the bicep tendon is ruptured

Shoulder injuries are often caused by

• muscle weakness
• aging
• poor posture
• all of these

A sign of a rotator cuff tear is

• a balled up tendon
• inability to abduct the arm above the shoulder
• bruising
• a bump on the AC joint

The most common rotator cuff strain usually happens in the

• bicep tendon
• subscapularis
• deltoid
• supraspinatus

Symptoms of a dislocated shoulder might be

• pain
• deformity of the deltoid muscle
• flat shoulder
• all of these

Treatment for a broken clavicle or AC joint separation might be

• a harness

• a cast

• bedrest 

• none of these
