The document provides information on examining the shoulder joint, including: 1) It describes the anatomy of the shoulder joint which involves three bones and three joints. 2) Common shoulder injuries include rotator cuff problems, impingement syndrome, and athletic injuries. 3) The physical exam involves inspection for atrophy or deformity, palpation of bony landmarks and soft tissues, and assessment of range of motion and strength. 4) Special tests examine for issues like instability, impingement, rotator cuff tears, biceps problems, and AC joint pathology.

hand

painful click / catch /
grind

77. history
• pain in the
• shoulder joint may be
referred from the neck,
chest or the abdomen
(from irritation of the
• diaphragm which is
supplied by the same
segments i.e. C3, 4 & 5

78. INSPECTION
• flattened due to wasting of the deltoid muscles
• from tuberculous arthritis, rheumatoid arthritis, osteoarthritis, rotator cuff*
lesions etc. It may
• be prominent with rotmded fullness seen in subdeltoid bursitis or effusion
of the joint. ln effusion
• of the shoulder joint, which is not very common, the swelling extends
beyond the anterior and
• posterior margins of the deltoid and along the long tendon of the biceps
due to existence of
• synovial sac. But in subdeltoid bursitis fullness is only seen just beneath
the deltoid muscle and
• does not go beyond the margins of this muscle

79. PALPATION
• .- The shoulder joint is best palpated by keeping the arm by
• the chest wall with one hand and with the other hand lo palpate the shoulder joint from all
• aspects. In supraspinatus tendinitis pressure just below the acromion process will elicit tenderness.
• In painful arc syndrome pressure just below the acromion will elicit tenderness if the arm is
• adducted, but not if the arm is abducted as the tender spot will disappear under the acromion
• process. Similarly in front just below the coracoid process one can feel the anterior aspect of the
• joint and note if there is any tenderness. Posteriorly also the joint is palpated similarly. In
• osteoarthritis if the arm is made to sway a little the palpating hand al the shoulder joint will
• feel the crepilus. Three bony joints are important to palpate in the shoulder joint - (a) Tip of
• coracoid, below which is the anterior aspect of the shoulder, (b) Tip of the acromion, below
• * 'Rotator cuff' is a cuff comprised of tendons of the four muscles which fuse with the
• capsule of the shoulder joint to give additional strength to it. These four muscles are - anteriorly
• subscapularis, superiorly supraspinatus and posteriorly infraspinatus and teres minor.
• 224 A MANUAL ON CLINICAL SURGERY
• which lies the superior aspect of shoulder and (c) Grea ter
• tuberosity, its prominence.
• It is a good practice to feel the acromioclavicular as well as
• the stemoclavicular joints to exclude any organic disease there.

80. I This is another method of pa lpating
Fig.15.1.- Note that the plane
of the scapula is not in the
coronal plane of the body but is
slightly inclined forwards (about
30°). Abduction and adduction
take place in the plane of the
body of the scapula (A-A)
whereas flexion and extension
occur at right angles to that plane.
CODMANS METHOD
The left hand is used to palpate the right
shouJder of the patient. The thumb lies along the depression
below the spine of the scapula to palpate the posterior aspect
of the shoulder joint. The tip of the index finger is placed just
anterior to the acromion to feel the superior aspect (at the
insertion of the supraspinatus) and slJghtly anterior aspect of
the joint and other three fingers a re )Placed on the clavicle to
hold it. Examiner's right hand grasps the patient's flexed elbow
and the patient's am1 is moved gently backwards (extension)
and forwards (flexion) and the sho ulder joint is carefully
palpated. The examiner's right hand is used to palpate patient's
left shoulder.

81. • , ~~t:llinp Effusion in the joint is difficult
to palpate
• through the deltoid. fullness, however,.
can be discovered in the
• ax ill a. Subdeltoid bursitis ma y give
rise to swelling and
• tenderness just beneath the acromion
process.
• The corresponding axilla should be
always palpated
• while exami.ning the affected shoulder.
This palpation
• should be deep high in the axilla to
detect any fullness
• there to indicate joint effusion. As the
inferior aspect of
• the joint is lax and redundant
accumulation of fluid
• starts here in case of joint effusion

82. • MOVEMENTS.- The shoulder joint is a very mobile
• joint and the bony configuration is such as to sacrifice
• the stability of the joint to certain extent to compromise
• with greater ranges of movement.
• While examining for the ranges of different
• movements of shoulder joint, firstly the patient must
• be stripped upto the waist and these movements should
• be examined not only from in front but also from
• behind (particularly during abducton to see the scapular
• movement). This is because of the fact that an
• ankylosed gleno-humeraJ joint will show some range
• of movement due to the movement of the scapula as
• also the acromioclavicular and sternoclavicuJar joints.
• Secondly the different movements must be compared
• with those of the normal side to exactly assess the
• differences. Thirdly the clinician must have a clear idea
• about the plane of the body of the scapula along which
• the abduction and adduction movements occur. This is
• not in the coronal plane of the body but is slightly

83. • inclined forwards about 30° with this plane (fig.15.1).
• Flg. 15 .2 .-- Codman' s method of
• palpation of the shoulder joint. Note the
• placement olf the clinician's fingers on the
• shoulder joint. See the text.
• EXAMINATION OF INDIVIDUAL JOIN'I PATHOLOGIES 225
• So during abduction the arm is carried forwards and outwards while during adduction the
• arm is carried backwards and inwards. Flexion and extension take place at right angle to this
• plane i.e. in flexion the arm is carried forwards and medially and in extension backwards and
• laterally. Fourthly in the movement of abduction the shoulder joint itself moves for 100°- 120°,
• the additional 60°-80° is obtained by the forward rotation of the scapula and some movement
• of the clavicle. But these movements occur a lmost simultaneously except in the initial 25°-30°
• when the whole of the movement takes place at the shoulder joint. For every subsequent 15°
• of elevation of the arm, the gleno-humeral joint contributes 10° and the scapular movemen t
• 5°. To note exactly how much movement is contributed by the gleno-humeral joint, the scapula
• is fixed by the clinician from behind and the patient is asked to abduct the shoulder.
• The range permitted in each movement is as follows : h
• Abduction - 180°; flexion - 90°; extension - 45°; •. :.;
• rotations - both medial and la teral - one quarter of a circle
• about a vertical axis; circumduclion - results from succession
• of the foregoing movements.
