This document provides an overview of the anatomy, articulations, ligaments, muscles, blood supply, and examination of the shoulder joint. It discusses the key bones (clavicle, scapula, humerus), joints (glenohumeral, acromioclavicular), ligaments (glenohumeral, coracohumeral), muscles (rotator cuff, deltoid), and nerves (brachial plexus, axillary, suprascapular) involved. It outlines the process for examining a patient with shoulder pain, including inspection, palpation, active and passive range of motion testing, and special tests (e.g. impingement tests, apprehen

4. Anatomy of shoulder joint
The shoulder is the region of upper attachment
to the trunk
The bone framework of the shoulder consists of :-
1. Clavicle ( Collarbone )
2. Scapula ( Shoulder blade )
3. Proximal end of the humorous
Roof of the shoulder form by the part of scapula
Acromion proses
5.
6. Articulation
Consist of a series of four articulation
1. The glenohumeral joint ( True shoulder joint )
2. The acromiocalvicular joint
3. The sternoclavicular joint
4. The scapulothoracic joint
7. Ligaments
Ligaments are soft tissues joining bone to bone in orthopedics
1. Glenohemural ligament
2. Transverse humeral ligament
3. Coracohumeral ligament
4. Accessory ligament ( Coraco acromial ligament )
5. Coracoa clavicular ligaments ( trapezoid and conoid lig )
Joint Capsule :- is water tight sac surround
shoulder joint. capsule enforced by group of ligaments
These ligaments are main source of stability

10. Muscle and Tendons
Anterior shoulder muscles:
Attach the upper extremity to the clavicle and
the thoracic cage :-
1. Pectoralis major
2. Pectoralis minor
3. Subclavius muscle
4. Serratus anterior muscle
11.
12. Rotator cuff
Is a group of four muscle that enclosed the
glenohumeral joint by forming the cuff around it :
1. Supraspinatus
2. Infraspinatus
3. Teres minor
4. Subscapularis muscles
Mnemonic SITS
• Produce large spectrum of arm movements
• External and internal arm rotation
• Abduction and arm adduction
13.
14. Other muscles
• Deltoid muscle
• Teres major muscle
From back
• Rhomboid major and rhomboid minor
• Trapezius
• Levator scapulae
• Litissimus dorsi
17. Nerve supply of joint
• Brachial plexus surrounds the axillary artery.
branches of plexus supply the shoulder region
• Axillary and suprascapular nerves
18. Shoulder joint
is an extremely mobile ball and Socket
synovial joint.
More prone to
injuries
Very
unstable
High
mobility
19. History
A patient with shoulder joint problems
presents with following complain
1. Pain
2. Swelling
3. Deformity
4. Loss of contour
5. Restriction and loss of movements
20. 1. Pain
Injuries Acute and sever pain
Chronic disorder pain is dull aching
Pain full arc syndrome pain during midrange
of abduction
Arthritis pain all over the shoulder
21. True shoulder pain
Radiate from near
tip of acromion
Down the lateral
side of arm
To the level of
deltoid insertion
Never extend below
the elbow joint
Referred
shoulder pain
From
Cervical spine
Heart
Mediastinum
and diaphragm
Shoulder pain
22.
23. 2. Swelling
Could be due to injury or arthritis
3. Deformity
Anterior dislocation Anterior prominence +
arm held in internal rotation
24. 4. Loss of contour
due to shoulder dislocation or deltoid muscle
wasting in TB , Rheumatoid arthritis etc
25. 5. Restriction and loss of movement
particularly due to frozen shoulder, arthritis etc
27. 1. Inspection (Look) :-
Examine patient at sitting position
From front
Sides
Behind
and above
28. From front
Look for the prominence of :
Sternoclavicular joint
Deformity of clavicle
Acromioclavicular joint
Wasting of the deltoid muscle due to axillary
nerve palsy or chronic disease like TB, Rheumatoid
arthritis
29. From behind
Look for
Position of scapula
Size of scapula
Wasting of supra – infra Spinatus muscle
Winging of the scapula
(due to paralysis of Serratus anterior )
30.
31. From above
Look for
Asymmetry of supraclavicular fossae
Swelling of the shoulder and any deformity
32. From the side
Look for
Swelling
Flattening ( Anterior dislocation ) or
( Rounded fellness of the joint ) ( effusion )
Note :-
Attitude :- In disease of shoulder Adopted are usually
flexion, adduction and medial rotation
Wasting of the Supraspinatus or Infraspinatus muscle
Wasting of deltoid or rotator cuff muscles
33. 2. Palpation ( Feel )
Local temperature
Tenderness
Swelling
Sensation
34. Local temperature: feel for the local rise of temp
Tenderness: try to elicit the tenderness along the
following points:
Just below the acromion Supraspinatus tendinitis
Just below the acromion and
the arm abducted sub deltoid bursitis
Along the Coracoid process this is the anterior
aspect of the joint
All round the joint arthritis
35.
36. Swelling :
Due to effusion in the joint best palpated in axilla.
Difficult to palpate through deltoid.
Beneath the Acromion process
Due to sub deltoid bursitis.
The sternoclavicular and the acromioclavicular
joint are also palpated for swilling , tenderness
etc
37. 3. movements
As already mentioned, shoulder joint is highly
mobile and consist of :-
1. Flexion normal range is 180
2. Extension normal range is 45
3. Abduction normal range is 180
4. Adduction
5. Rotations
38. Flexion
Best tested with the patient seated position
Both passive and active movements are testes
40. Abduction
• Best tested in standing position and both the
shoulder are tested simultaneously for
comparison.
• This is the most important movement of
shoulder
• Normal range is 180
41. Pain in abduction :-
Initial :- Supraspinatus rupture
Midrange pain and extremes of movement
painless : Sub Acromial bursitis
More than 90 :- ACM joint arthritis
All trough :- Glenohumral arthritis
Out of 180 abduction :- 100 – 120 is by
glenohumeral 60 - 80 is by scapula and clavicle
thus abduction can still take place even if
glenohumeral joint is ankylosed
43. Rotation
Both internal and external rotation are tested
in supine and sitting position.
Internal rotation :
Ask the patient to touch their back with the
dorsum of the hand and to raise their hand up
the back high as possible ( Normal range is
thoracic spine level T7- T9 )
44.
45. External rotation :
With the arms by the sides, bend the elbow to
90 and rotate the forearm to the mid – prone
position. Ask the patient to separate their
hands as much as possible
46.
47. Impingement syndrome
Impairment or compression of the rotator cuff
tendons in the subacromial space between
the lateral aspect of the acromion and the
humeral head
May result in rotator cuff
tendonitis/tendinopathy , subacromial
bursitis, and degenerative rotator cuff tear.
Partial or full-thickness tear.
48.
49. • Pain full arc test :
Ask the patient to abduct their arms from their
sides. The presence of pain from 60 – 120 is
positive.
50. Jobe’s test ( Empty can ) :
Ask the patient to abduct the arm to 90 elevation in
the scapular plane with full internal rotation
( empty can position ). Ask the patient to resist
downward pressure the presence of pain is
positive.

52. Shoulder instability
• Instability may be defined as a shoulder that
slips in and out of joint (dislocation) more
than once or twice, or frequently slips partially
out of joint and then returns on its own.
instability can be anterior, posterior, inferior or
multidirectional.
53. Apprehension test
With the patient supine or standing , flex the
elbow to 90 and abduct the shoulder to 90.
now externally rotate the shoulder
apprehension indicates anterior instability.
54. Other examination
Examine the cervical spine.
Examine the acromioclavicular and
sternoclavicular joints
Neurovascular examination of the upper limbs
Winging of scapula long thoracic nerve of bell is
paralyzed
Regimental badge anesthesia and loss of deltoid
power damage to axillary nerve
Systemic examination for TB, rheumatoid arthritis
