2 End point diagnosis End point diagnosis: *Rotator Cuff Tear It could be this: *Tendonitis *Labral Tear *Impingement *Adhesive Capsulitis *Referred shoulder pain from other source

3 Rotator Cuff Anatomy

4 Anatomy Supraspinatus Origin: Supraspinatus scapular fossa Insertion: Superior facet on greater tubercle of humerus Action: Initiates abduction at shoulder and externally rotates humerus Infraspinatus Origin: Infraspinatus scapular fossa Insertion: Middle facet on greater tubercle of humerus Action: Externally rotates the humerus Teres Minor Origin: Lateral border of scapula Insertion: Inferior facet on greater tubercle of humerus Action: Externally rotates humerus and weakly adducts the arm at shoulder Subscapularis Origin: Subscapular fossa and from lower 2/3 of lateral border of scapula Insertion: Lesser tubercle of humerus and anterior portion of shoulder joint capsule Action: Internally rotates and adducts the humerus at shoulder ***All four muscles draw the humerus toward the glenoid fossa, strengthening the shoulder joint

5 Mechanism of Injury Acute Tear: If you fall down on your outstretched arm or lift something too heavy with a jerking motion, you can tear your rotator cuff. This type of tear can occur with other shoulder injuries, such as a broken collarbone or dislocated shoulder. Degenerative Tear: Most tears are the result of a wearing down of the tendon that occurs slowly over time. This degeneration naturally occurs as we age. Several factors contribute to degenerative, or chronic, rotator cuff tears. Repetitive stress. Repeating the same shoulder motions again and again especially overhead motions can stress your rotator cuff muscles and tendons. Overhead sports and many jobs and routine chores can cause overuse tears, as well. Lack of blood supply. As we get older, the blood supply in our rotator cuff tendons lessens. Without a good blood supply, the body's natural ability to repair tendon damage is impaired. This can ultimately lead to a tendon tear. Bone spurs. As we age, bone spurs (bone overgrowth) often develop on the underside of the acromion bone. When we lift our arms, the spurs rub on the rotator cuff tendon. This condition is called shoulder impingement, and over time will weaken the tendon and make it more likely to tear.

6 Rotator Cuff Tear Partial Tear: This type of tear damages the soft tissue, but does not completely sever it. Full-Thickness Tear: This type of tear is also called a complete tear. It splits the soft tissue into two pieces. In many cases, tendons tear off where they attach to the head of the humerus.

7 Risk Factors

8 Age As you get older, your risk of a rotator cuff injury increases. Rotator cuff tears are most common in people > 40.

9 Poor Posture Forward-Shoulder Posture o Can cause a muscle or tendon to become irritated and inflamed when you throw or perform overhead activities

10 Weak Shoulder Muscles Abductors and External Rotators o This risk factor can be decreased or eliminated with shoulder-strengthening exercises, especially for the less commonly strengthened muscles on the back of the shoulder and around the shoulder blades.

11 Repetitive Overhead Lifting Athletes o tennis players o baseball pitchers Occupation o painters o carpenters o others who do overhead work

12 Traumatic Injury History of falls History of any other shoulder injury

13 Signs and Symptoms MOI FOOSH with arm abducted or extended Sudden jarring/sharp loading Lifting from floor O-linemen strike Gradual onset d/t impingement and fraying Location of Pain Supraspinatus: outer aspect of shoulder to deltoid insertion, may radiate to elbow Infraspinatus: posterior aspect of shoulder, may radiate down posterior arm Subscapularis: local discomfort

14 Signs and Symptoms Description of Pain Intermittent At rest: superficial, local, anterior After activity: deep ache, may radiate to elbow AM/PM Night pain Can’t sleep on affected shoulder Feeling of weakness Can’t comb hair, reach into cabinet, lift light-mod weight items Supraspinatus and ER specifically

15 Signs and Symptoms Observation Atrophy of Muscle: Hollowed supraspinatus/infraspinatus fossa Shoulder Hike: upper trap/deltoid compensation during movement Limited AROM Full PROM

16 Primary Tests for Rotator Cuff Tear Empty Can Test Drop Sign Hand Behind Back – Lift Off Test Hornblower Sign

17 Empty Can Test Patient elevates shoulder to 90° of scaption with thumb pointed down. The clinician applies resistance. Positive response is if there is weakness or pain in the supraspinatus region. Test is indicative of supraspinatus tendonitis or a supraspinatus tear.

18 Drop Sign The PT will passively move the patients arm to 90° of abduction with the elbow bent at 90°. A positive sign is if the patient is unable to hold their arm in that position due to weakness and pain the rotator cuff area. Test is indicative of infraspinatus tear.

19 Hand Behind Back – Lift Off Test The PT will put help the patient get into a position where they put the arm fully extended and internally rotated where they touch their lower back with the back of their hand. A positive sign is if the patient is unable to lift the back of the hand off their back. This is indicative of subscapularis weakness or tear.

20 Hornblower Sign The PT will put patient’s arm in 90° of abduction in scapular plan. The elbow is flexed at 90°. The patient will try to ER forearm against the resistance of the PT. A positive sign is if the patient cannot externally rotate their arm, and they assume a position of a positive hornblower sign. This test is indicative of teres minor tear.

21 Other Tests to Perform Subacromial Impingement Tests Hawkins-Kennedy Impingement Test Supraspinatus tendon impingement Can be positive if have a rotator cuff tear. Neer’s Test Supraspinatus tendon impingement Labral Tear Tests Crank Test SLAP lesions Speed’s Test Superior labral tear / Bicipital tendonitis O Brien’s Test Labral tear

22 Other Tests to Perform Shoulder Stability Tests Sulcus Sign Multidirectional instability/inferior stability Load and Shift Test Anterior and posterior instability of glenohumeral joint Apprehension Test Anterior instability Relocation Test Anterior instability

23 Algorithm

24 TAKE HOME MESSAGE This algorithm can assist physical therapists by giving them a set of steps to follow if their patient is displaying the signs and symptoms associated with a rotator cuff tear. The physical therapist can then follow the steps in the algorithm to come to a diagnosis for their patient and treat them accordingly.
