Anatomy – Shoulder joint complex
Glenohumeral joint Acromioclavicular joint Sternoclavicular joint Scapulothoracic joint Shoulder complex consists of 4 joints: GH, AC, SC, Scapulothoracic Glenohumeral jt is a ball and socket jt formed between the humerus and scapula. The humeral head is much larger than the glenoid socket resulting in high mobility at the cost of less stability. The stability is provided by other structures such as the glenoid labrum, joint capsule, negative intra-articular pressure, muscles and ligaments.

Anatomy - Rotator Cuff Muscles
Supraspinatus Infraspinatus Teres Minor Subscapularis SS Origin: medial 2/3 of supraspinous fossa Insert: upper three facets of greater tuberosity Stabilises the head in the glenoid. Helps depress head of humerus. It works with deltoid during Abduction especially in range of 0-30 degrees IFS Origin: medial 2/3 infrapsinous fossa Inserts: lateral 3 facets of grt tuberosity Produces lat rot, helps depress head of humerus TM Origin: lateral 2/3 scapula Inserts: lower lat three facets grt tuberosity Assists lat rot of GH joint with Infrapsinatus. SScp Origin: Medial 2/3 of subscapular border on costal surface. Inserts: Lesser tuberosity, reinforces capsule. Provides medial rot of joint.

Here you can see the anterior aspect of the rotator cuff
Here you can see the anterior aspect of the rotator cuff. Subscapularis attaches medial to the bicipital groove, on the lesser tuberosity. The long head of biceps runs from the supraglenoid tubercle through the joint making it intra-articular. In the bicipital groove it is held in place by the transverse humeral ligament formed with fibers from subscapularis. Suprapsinatus attaches on the superior facet of the greater tuberosity You can also see the coraco-acromial ligament forming the coraco-acromial arch and also the acromioclavicular ligament between the acromion and the clavicle.
6
Anatomy - Rotator cuff posterior aspect
At the posterior aspect of the rotator cuff there are the insertions of IFS and TM which attach lateral to the bicipital groove, on the greater tuberosity.

Pathologies Impingement Syndrome Rotator cuff tear ACJ Labral lesions
LHB TOS Referred Pain

Impingement External Internal
External impingement (Sub-acromial Impingement Syndrome) Primary Bony abnormalities in the shape of the acromial arch Bone spurs Calcification Secondary Poor scapular stabilisation Weakness of the rotator cuff Muscular imbalance between deltoid and rotator cuff muscles. Impingement Syndrome can be classified as external or internal: External impingement can be either primary or secondary: Primary: This is usually due to bony abnormalities in the shape of the acromial arch, degenerative changes such as bone spurs from the arch or calcification. These bony abnormalities impinge on the tendons. Secondary Usually due to poor scapular stabilisation which alters the physical position of the acromion, reduces the sub-acromial space and causes impingement on the tendons. Other causes can include weakening of the rotator cuff tendons due to overuse or muscular imbalance between the deltoid muscle and rotator cuff muscles.
9
Impingement Internal Impingement (Posterior Superior Glenoid Impingement) Articular side of Supraspinatus becomes impinged between the greater tuberosity and the posterosuperior labrum. Abduction and external rotation are affected. Pain at the posterosuperior aspect of the shoulder Internal impingement (Posterior Superior Glenoid Impingement) Articular side of Supraspinatus becomes impinged between greater tuberosity and posterosuperior aspect of glenoid rim. Abduction and external rotation are affected. The under side of the rotator cuff tendons are impinged against the glenoid labrum – this tends to cause pain at the back of the shoulder joint Pain at the posterosuperior aspect of the shoulder Condition may be seen in sports such as throwing or manual jobs such as painting with prolonged position of arm overhead in abduction and lateral rotation
10
Subacromial Impingement Syndrome (External)
Subacromial space Space 9-10mm Arm elevation – superior head displacement Rotator Cuff muscles Provide dynamic stability Work with deltoid Prevent superior translation of HH RC – Deltoid balance Subacromial space is formed by the coraco-acromial arch (constituting acromion, coraco-acromial ligament and coracoid process) above and the superior aspect of the humeral head below. The space measures about 9-10 mm As arm elevation occurs, there is a 3mm superior displacement at the centre of motion, whereby the RC tendons then activate RC muscles Provide dynamic stability to the GH joint. RC tendons work with deltoid during elevation movements preventing superior translation of humeral head Deltoid acts to abduct arm but also creates superior translation of the head RC muscles act to maintain the humeral head central within the glenoid and depress the head. When there is weakness of the RC, the deltoid is not counteracted and results in superior translation and impingement.

Supraspinatus tendon Long head biceps tendon Subacromial bursa Superior border of capsule
12
Causes of Impingement Instability/hypermobility
RC overuse or tendinopathy Tight posterior GH capsule Poor scapular muscle control Poor Posture Instability/hypermobility due to RC failure or weakness resulting in excessive translation of the humeral head. Excessive translation may lead to RC tendinopathy RC overuse or tendinopathy which leads to thickening of the tendon and reduced sub-acromial space Tight posterior GH capsule leads to superior and anterior translation of the humeral head which leads to reduced sub-acromial space and impingement. Poor scapular muscle control or abnormal scapular rhythm positioning the scapula in an excessive downward rotated position, reducing acromial elevation and resulting in impingement. This may be due to poor serratus anterior or Lower trapezius activity and poor eccentric control as these are the main scapular upward rotators or may be due to shortening of pectoralis minor and levator scapulae. Poor posture is often associated with FHP and increased thoracic kyphosis. This results in an anterior translation of the humeral head in relation to the trunk which is one of the factors to impingement
13
Causes of impingement Poor Tx spine extension – reduced GH elevation
Increased Tx kyphosis and FHP (forward head posture) will cause: scapulae to abduct resulting in lengthening of rhomboids and LFT shortening of serratus anterior, latt dorsi, subscap – reduced scapular upward rotation shortening of pect major and pect minor pull the coracoid process downwards bringing the acromion over the head of the humerus causing a mechanical block to arm elevation reduced subacromial space Poor Tx spine extension (or Tx khyphosis ) can lead to poor GH elevation – limiting the last 15 degrees of elevation An increased Tx kyphosis and FHP will cause the scapulae to abduct resulting in lengthening of rhomboids and lower fibres of trapezius shortening of serratus anterior, latt dorsi, subscap. This leads to reduced upward rotation of the scapula during glenohumeral elevation. There is also shortening of pect major and pect minor. Since Pect minor attaches to coracoid process it will tend to pull the coracoid process downwards, bringing the acromion over the head of the humerus causing a mechanical block to arm elevation and reduced subacromial space.

15
Treatment Correct biomechanics of shoulder joint complex
Correct posture Increase Tx mobility Lengthen shortened muscles Release tight posterior capsule or posterior cuff Strengthen weaker muscles esp. RC and scapular upward rotators – SA and LFT Correct biomechanics of shoulder joint complex Correct posture Increase Tx mobility by mobilisation of Tx and extension exercises Lengthen shortened muscles particularly pectoralis minor; Pectoralis major Release tight posterior capsule or posterior cuff Strengthen weaker muscles esp. RC and scapular upward rotators – SA and LFT Will show examples of treatment later on
16
RC Tear Partial or Full Overhead activity, trauma or recurrent impingement If atraumatic - chronic diffuse pain more than 3 months Common in over 40’s - Tendonosis, smoking, steroids, RA, Diabetes Affects 7% of elderly Unable to sleep on effected shoulder Limited internal rotation, passively painful A RC tear can be Partial or full The RC can tear with repetitive overhead activity, trauma or recurrent impingement If atraumatic, it develops as chronic diffuse pain for more than 3 months Common in over 40’s as Tendonosis with PDF such as smoking, steroids, RA, Diabetes Affects 7% of elderly Unable to sleep on effected shoulder Limited internal rotation, passively painful studies have shown that approx 40% of individuals older than 60yrs had full thickness rotator cuff tears. However the relationship between pain, function and RC tear does not always correlate with painful shoulder dysfunction. Once the tendon tears, it compromises the functional stability of the GH joint leading to impingement.

19
Labral lesions Superior – SLAP Bankart lesion Causes FOOSH
Repetitive movements Strong biceps contraction Glenoid labrum injuries may be classified as superior - known as a SLAP lesion (superior labrum, anterior to posterior) and is a tear of the labral rim above the middle of the socket that runs from anterior to posterior region and may also involve the biceps long head tendon. This occurs most commonly with fall on outstretched hand. Bankart labral lesion is a tear of the labral rim at an anteroinferior position, below the middle of the glenoid socket and also involves the inferior glenohumeral ligament. This creates instability and makes the shoulder prone to recurrent dislocations. Causes FOOSH Tears of the glenoid labrum may often occur with other shoulder injuries, such as a dislocated shoulder. Repetitive movements that create excessive motion at the glenohumeral joint such as throwing. Activities that require the biceps muscles to contract sharply against the labrum such as lifting heavy weight. Bonding strength of labrum to glenoid increases with age and therefore labral tears are more likely in the younger population. Symptoms The symptoms of a labral tear may include a clicking or catching sensation in the shoulder during certain movements and/or a vague pain in the front or top of the shoulder.
20
Symptoms of glenoid labrum tears
Clicking or catching with shoulder movements Vague pain at front or top of shoulder Pain is made worse by overhead activities or when the arm is held behind the back. Weakness and Instability in the shoulder. Pain on resisted flexion of the biceps Symptoms The symptoms of a labral tear may include a clicking or catching sensation in the shoulder during certain movements vague pain in the front or top of the shoulder. Pain is made worse by overhead activities or when the arm is held behind the back. Weakness and Instability are present in the shoulder. Pain on resisted flexion of the biceps
21
Labral SLAP tests O’Brien Active Compression Test Crank test
Pt stdg, flexion 90°, adduction 15° with elbow extended Full MR so thumb pointing down Resist flexion Pt laterally rotates arm so thumb pointing up Positive test = Pain or painful clicking elicited with thumb down and decreased or eliminated with thumb up Crank test Shoulder elevated to 160° in the scapular plane A gentle axial load is applied through glenohumeral joint with one hand, while other hand does IR and ER Positive test = pain, catching, or clicking in the shoulder Practical Demonstration O’Brien Active Compression Test Pt stdg, flexion 90°, adduction 15° with elbow extended Full MR so thumb pointing down Resist flexion Pt laterally rotates arm so thumb pointing up Positive test = Pain or painful clicking elicited with thumb down and decreased or eliminated with thumb up In test position biceps tendon is displaced medially and inferiorly, tensioning the bicipital labral complex, creating shear forces in the glenoid and labrum resulting in deep, anterior pain and clicking. This position is similar to the cross body adduction test for ACJ, however the site of pain is different with ACJ dysfunction being be more superior and less deep and due to the greater tuberosity being locked under the acromion and moved out of the way by supination. Crank test Shoulder elevated to 160° in the scapular plane A gentle axial load is applied through glenohumeral joint with one hand, while other hand does IR and ER Positive test = pain, catching, or clicking in the shoulder

25
TOS Interscalene triangle Costoclavicular triangle Subcoracoid space
The brachial plexus trunks and subclavian vessels are subject to compression or irritation as they course through 3 narrow passageways from the base of the neck toward the axilla and the proximal arm. The most important of these passageways is the interscalene triangle,formed by the anterior scalene muscle anteriorly, the middle scalene muscle posteriorly, and the medial surface of the first rib inferiorly. Structures such as fibrous bands or cervical ribs may constrict this triangle. Anterior scalene tightness causing Compression of the interscalene space between the anterior and middle scalene muscles may be probably due to nerve root irritation, spondylosis or facet joint inflammation leading to muscle spasm. The second passageway is the costoclavicular triangle, which is bordered anteriorly by the middle third of the clavicle, posteromedially by the first rib, and posterolaterally by the upper border of the scapula. Costoclavicular approximation resulting in Compression in the space between the clavicle, the first rib and the muscular and ligamentous structures in the area may be probably due postural deficiencies or carrying heavy objects. The last passageway is the subcoracoid space beneath the coracoid process just deep to the pectoralis minor tendon. Pectoralis minor tightness resulting in Compression beneath the tendon of the pectoralis minor under the coracoid process-may result from incorrect posture or frequent sitting at desk jobs

Referred Pain : Cervical
28
Referred Pain: Gastro-Intestinal
Liver : R shoulder Gall bladder: R shoulder and R scapula Diaphragm : unilateral / bilateral shoulder pain Spleen: L shoulder + upper 1/3 arm Aortic Aneurysm: L scapula Cardiac: L shoulder + Scapula Post Laparoscopy: uni / bilateral shoulder pain Liver : R shoulder Gall bladder: R shoulder and R scapula Diaphragm : unilateral / bilateral shoulder pain Spleen: L shoulder + upper 1/3 arm Aortic Aneurysm: L scapula Cardiac: L shoulder + Scapula Post Laparoscopy: uni / bilateral shoulder pain Liver, Gall bladder and duodenum all can irritate the diagphragm which is innervated by C3, C4 C5. C3 C4 spinal cord levels also receive sensory input via the supraclavicular nerves. So when pain is elicited from abdominal organs it may be felt as referred pain in the shoulder. Laparascopy involves the injection of CO2 gas in order to better view the organs. This results in irritation of the diaphragm and the phrenic nerve, resulting in referred pain.

Referred Pain: Pancoast Tumour
Tumour of apex of lung Invade chest wall structures such as Lymphatics Lower roots of brachial plexus (esp. C8, T1) Intercostal nerves Sympathetic chain and Stellate ganglion Adjacent ribs Initial symptom is pain in the shoulder and medial aspect of scapula Referred pain to C8, T1, T2 dermatomes Horner’s syndrome later develops Pt supports arm to relieve neural tension Hand muscles later develop atrophy Pancoast tumour originates at the apex of the lung. It mainly extends into the chest wall structures rather than the underlying lung tissue. Invade chest wall structures such as Lymphatics Lower roots of brachial plexus (esp. C8, T1) Intercostal nerves Sympathetic chain and Stellate ganglion Adjacent ribs The initial symptom is pain in the shoulder and medial part of the scapula Referred pain to C8, T1, T2 dermatomes Horner’s syndrome later develops – drooping eyelid, reduction in size of pupil Patient supports arm to relieve neural tension Hand muscles later develop atrophy

Exercises Scaption instead of Abduction
Better joint congruence Reduced tensile forces on ligaments Optimal sub-acromial space and clearance Optimal alignment of RC muscles Increased proprioceptive feedback Increased activation of scapula upward rotators and RC muscles Exercises for RC with minimization of deltoid and Upper Fibres Trapezius activity Scaption instead of Abduction Scaption is flexion of the GHJ in the plane of the scapula Better joint congruence Increased proprioceptive feedback Reduced tensile forces on ligaments at superior and anterior aspects of shoulder Optimal sub-acromial space and clearance of greater tuberosity Optimal alignment of RC muscles Optimal activation of scapula upward rotators and RC muscles Exercises for RC with minimization of deltoid activity and UFT Due to the imbalance often present between RC and deltoid resulting in superior migration of the humeral head, it is important when giving exercises to try to eliminate activation of deltoid. Also important to eliminate UFT activation due to their frequent overactivity resulting in elevation of the scapula and reduction of sub acromial space.
