16. ROLE OF ULTRASOUND
Ultrasound is essentially used for the rotator cuff complex of the shoulder.
Ultrasound is a valuable diagnostic tool in assessing the following indications;
Muscular, tendinous and some ligamentous damage (chronic and acute)
Bursitis
Joint effusion
Vascular pathology
Haematomas
Soft tissue masses such as ganglia, lipomas
Classification of a mass e.g solid, cystic, mixed
Post surgical complications e.g abscess, edema
Guidance of injection, aspiration or biopsy
Some bony pathology.
LIMITATIONS
It is recognised that ultrasound offers little or no diagnostic information for internal
structures such as the gleno-humeral ligaments. Ultrasound is complimentary with other
modalities, including plain X-ray, CT, MRI and arthroscopy.
EQUIPMENT SELECTION AND TECHNIQUE
Use of a high resolution probe (7-15MHZ) is essential when assessing the superficial
structures of the shoulder. Careful scanning technique to avoid anisotropy (and possible
misdiagnosis) Beam steering or compounding can help to overcome anisotropy in linear
structures such as tendons. Good colour / power / Doppler capabilities when assessing
vessels or vascularity of a structure. Be prepared to change frequency output of probe
(or probes) to adequately assess both superficial and deeper structures.

17. Shoulder Ultrasound Technique
Lennard Funk, 2008
Indications
Indications for ultrasound scanning of the shoulder include:
Suspicion of rotator cuff pathology
Full thickness cuff tears
Partial thickness tears
tendonitis/tendinosis
Calcific tendonitis
Subacromial impingement / bursitis
Long Head of Biceps pathology such as tendonitis or tears, subluxation or
dislocations.
Acromioclavicular Joint pathology such as arthritis, osteolysis and
subluxations.
Glenohumeral pathologies such as:
Glenohumeral arthritis (osteophytes).
Glenohumeral effusions.
Rarely, labral pathology .
Bony lesions such as Hill-Sachs Lesions

18. PATIENT POSITION
Patient seated on chair in front of ultrasound machine. Have the patient's chair at
an appropriate height to be ergonomically comfortable for you to scan.
LONG HEAD BICEPS (BT):
For example images of pathology, click here to go to the shoulder pathology
page.
Patient rests hand palm up on thigh.
Scan transversely over the anterior humeral head.
Visualize the bicipital groove. Identify the biceps tendon in the groove (if not
identified it may be either torn or subluxed medially out of the groove). Follow
down to the muscle belly.
Rotate into longitudinal and re-examine.
The tendon should be a uniform fibrillar structure, generally less than 5mm thick.
Examine dynamically in a transverse plane during internal/external rotation to
ensure it doesn't subluxed medially.
SUBSCAPULARIS (SSC):
For example images of pathology, click here to goto the shoulder pathology page
Again in a transverse plane at the bicipital groove, externally rotate the patient's
arm.
The SSC tendon will be visible inserting medial to the groove.
It will be seen as an elongated slightly convex tendon

19. SUPRASPINATUS (SSP)
For example images of pathology, click here to goto the shoulder
pathology page
Position the patient palm up with their elbow flexed and pulled back
passed their side so their hand is near their hip.
Identify the SSP tendon supero-lateral to the bicipital groove. In a coronal
plane, the tendon emerges from beneath the acromion to insert on the
greater tuberosity of the humerus.
It should be uniform, fibrillar & 'beak shaped' (convex superiorly).
INFRASPINATUS (ISP)
For example images of pathology, click here to goto the shoulder
pathology page
Ask the patient to place their affected hand across their chest towards the
contralateral shoulder.
The ISP can be seen by placing the probe immediately inferior to the spine
of the scapula and following the tendon to it's insertion postero-laterally
on the humeral head.
It will have a similar appearance to subscapularis.

20. DYNAMIC ASSESSMENT
Biceps: assess it's stability within the bicipital groove during external rotation.
Subscapularis: assess for any overlying subdeltoid bursal bunching against coracoid during
internal rotation
Supraspinatus: assess for bunching of the tendon &/or overlying subacromial bursa against
the acromion or coraco-acromial ligament during abduction.
Ensure the patient does NOT hunch their shoulder or lean towards the contralateral side
during abduction.
Posterior joint recess: during internal/external rotation, assess for a gleno-humeral joint
effusion. This will be most evident during external rotation
Acromio-clavicular joint: During forward flexion with internal rotation look for boney contact
or ganglia of the ACJ.
A shoulder series should include the following minimum images:
Long head biceps tendon - long, trans
Subscapularis tendon
Coraco-acromial ligament
Supraspinatus tendon
Infraspinatus tendon
Acromio-clavicular joint
Posterior joint recess
Pre & post abduction views
Document the normal anatomy. Any pathology found in 2 planes, including measurements
and any vascularity. Detail any limitation to range of movement and degree that pain or
symptoms begin.

21. Rotator Cuff Injury and Inflammation.
Rotator cuff injury and inflammation is one of the most common causes of
shoulder pain. There are three common conditions that can affect the rotator
cuff: rotator cuff tendonitis, rotator cuff impingement syndrome and a rotator
cuff tear. Most people with rotator cuff problems can be successfully treated
by a combination of rest, painkillers, anti-inflammatories, physiotherapy and
steroid injections. Surgery is sometimes an option.
US Imaging.—Sonographic findings for a full-thickness rotator cuff tear
include nonvisualization or absence of cuff tissue, a full-thickness hypoechoic
defect, focal thinning, loss of the convexity of the outer cuff contour, ability to
compress the deltoid muscle within a defect or against the humeral head,
visualization of the underlying hyaline cartilage (“naked cartilage sign”) a
heterogeneously hypoechoic cuff with bursal fluid, and severe distortion of
cuff architecture. In consideration of studies with surgical correlation,
reported sensitivities and specificities for US range from 57% to 95% and 76%
to 94%, respectively. Not surprising, the sensitivity increases as the size of the
tear increases, with sensitivity for massive cuff tears (>3 cm) approaching
100%.

22. Sonographic detection, localization, and characterization of
partial-thickness cuff tears have been described only recently.
Proposed criteria include a hypoechoic defect that involves the
articular or bursal surface, a focal hypoechoic zone within the
substance of the cuff, a large linear echogenic focus within the
cuff substance, thinning of the cuff (marked during passive
movement), and a straight outer cuff border (loss of convexity).
Criteria that address intrasubstance findings may produce a
relatively high false-positive rate because these “defects” may
not be visualized by means of correlative methods such as
arthrography, arthroscopy, and surgery. Van Holsbeeck et al
achieved 93% sensitivity and 94% specificity with two criteria: a
mixed hyper- and hypoechoic region or a hypoechoic discontinuity
that involves either the bursal or articular surface. The former is
attributed to penetration of torn cuff fibers by joint fluid. An
associated finding described by these investigators is that of
“pitting” of the greater tuberosity

23. Full-thickness cuff tear in a 74-year-old woman. A, The longitudinal image shows
that the cuff is retracted medially, and the torn tendon end (T) is surrounded by
fluid. B, The transverse image shows the width of the tear (between cursors).

24. Large, full-thickness tear of the rotator cuff. Coronal (longitudinal) sonogram shows a
large cuff defect filled with fluid and debris (straight arrows). Also apparent are the
medially retracted edge of the supraspinatus tendon (curved arrow), near apposition
of the deltoid muscle (D) to the humeral head, and loss of outer convexity.

25. Massive full-thickness tear of the rotator cuff. (a) Coronal (longitudinal) US image
demonstrates a massive rotator cuff tear, the gap filled with hypoechoic fluid (straight
arrows). The underlying hyaline cartilage is exposed (naked cartilage sign) (curved
arrows). (b) Coronal US image obtained with manual compression of the same region of
the cuff shows apposition of the deltoid muscle (D) to the underlying humeral head (solid
arrows). An osseous excrescence appears at the articular margin (open arrow).

26. Full-thickness tear of the rotator cuff. (a) Coronal (longitudinal) US image shows a full-
thickness defect of the rotator cuff filled with both fluid and debris (straight arrows).
Delamination of the cuff is apparent, with more medial retraction of the deep (solid
curved arrow) as opposed to the bursal (open arrow) aspect. In addition, the specular
reflector of the articular surface abuts fluid, resulting in the naked cartilage sign (open
arrowheads). There is minor osseous irregularity (solid arrowheads).

27. Full-thickness tear of the supraspinatus tendon. (a) Longitudinal US image demonstrates a
full-thickness hypoechoic defect in the normal location of the supraspinatus tendon
(arrows). This defect represents fluid and extends from the bursal surface to the articular
surface. Note the torn edge of the retracted supraspinatus tendon (S). (b) Transverse US
image shows an intact infraspinatus tendon (i) posterior to the tear. The double cortex sign
can also be seen; the overlying fluid accentuates the appearance of the cartilage (arrows),
which is almost as hyperechoic as the underlying cortex.

28. Full-thickness tear of the rotator cuff.

29. Partial-thickness tear of supraspinatus tendon. (A) Short-axis view. There is a partial-thickness
articular surface tear in the mid-substance of the tendon (between markers) with a few intact
fibers overlying (arrow). (B) Partial-thickness bursal surface tear (arrow) of the supraspinatus
tendon. (C) Partial-thickness intrasubstance tear (arrow). (D) Partial tear (rim rent) of
supraspinatus tendon at greater tuberosity (arrow). BT: Biceps tendon, HH: Humeral head

30. Partial, undersurface tear of the rotator cuff. Coronal (longitudinal) US image shows
mixed echogenicity of the undersurface of the cuff (straight arrows) that reflects
torn cuff fibers and adjacent fluid. The bursal fibers are intact (curved arrows

31. Partial-thickness, undersurface tear of the rotator cuff. Transverse sonogram
demonstrates a hypoechoic region (open arrow) along the undersurface of the
supraspinatus tendon (SS). The adjacent greater tuberosity is pitted (solid arrows

33. Subscapularis tendon tear with subluxation of the long head of the biceps tendon. Transverse
US image (a) and axial proton-density–weighted MR image (b) show a tear of the
subscapularis tendon (arrow), with the biceps tendon (b) perched on the lesser tuberosity (L).

34. Partial tear of the cranial half of subscapularis tendon.

35. Tendinosis. On a longitudinal US image, the supraspinatus tendon (arrows)
is thickened and heterogeneous with no discrete defects. Instead, an ill-
defined hypoechoic defect with indistinct borders is seen (*).

36. Marked tendinopathy. The longitudinal image shows a hypoechoic and very thickened cuff.

37. Calcific tendinitis. (a) Radiograph demonstrates deposition of calcium hydroxyapatite (arrow)
just superior to the greater tuberosity at the insertion site of the supraspinatus tendon. (b) US
image shows calcium deposition within the supraspinatus tendon as a lobular echogenic area
without shadowing (arrows). Note also the effusion in the subdeltoid bursa (*).

38. Supraspinatus tendon calcifying tendonitis.

39. Subacromial bursitis is a common cause of shoulder pain that is usually
related to shoulder impingement of your bursa between your rotator cuff
tendons and bone (acromion). Your subdeltoid bursa is less commonly
inflamed shoulder bursa.
Ultrasound show fluid distension, synovial proliferation, thickening of the
bursal wall.
Subacromial-
subdeltoid
bursal effusion.

40. Subdeltoid bursitis. Longitudinal US image of the biceps tendon demonstrates a
fluid collection (arrows) superficial to and not involving the biceps tendon (b).

41. Subacromial subdeltoid bursitis.

42. Shoulder joint effusion tracking into the biceps tendon sheath. Transverse US
image (a) and axial gradient-echo MR image (b) demonstrate an effusion in the
biceps tendon sheath (arrows). The box in b corresponds to the field of view in a.

43. Biceps tendinitis is inflammation of the tendon around the long head of the
biceps muscle. Biceps tendinosis is caused by degeneration of the tendon from
athletics requiring overhead motion or from the normal aging process.
Inflammation of the biceps tendon in the bicipital groove, which is known as
primary biceps tendinitis. Biceps tendinitis and tendinosis are commonly
accompanied by rotator cuff tears or SLAP (superior labrum anterior to posterior)
lesions. Patients with biceps tendinitis or tendinosis usually complain of a deep,
throbbing ache in the anterior shoulder. Repetitive overhead motion of the arm
initiates or exacerbates the symptoms. Ultrasonography is preferred for
visualizing the overall tendon, whereas magnetic resonance imaging or computed
tomography arthrography is preferred for visualizing the intraarticular tendon and
related pathology.
Ultrasound appearance of tendinosis depends on extensity and the time between
injury and sonographic evaluation. In acute tendinosis, initially, tendon is
thickened, with normal contour and echo structure. As the process progresses, the
fibrillar pattern is lost and tendon becomes hypoechoic, with further swelling.
Discrete focal hypoechoic areas may represent small partial tears, which may not
extend to the tendon surface. But if a defect is present on the tendon surface,
dynamic evaluation (i.e., during movement) should be performed to rule out
partial tear. Increased Doppler flow can point to hyperemia that can be associated
with tendinopathy.

45. Biceps brachii tendon tear. Longitudinal scan of the bicipital groove shows
proximal retraction of the biceps muscle (long arrow). A fluid-filled gap
with echogenic clots (small arrow) at the myotendinous junction.

46. Biceps brachii tendon synovitis. Axial scan of the biceps tendon shows fluid
and synovial thickening (arrow) surrounding the biceps tendon sheath.

47. Biceps tendon subluxation. Transverse scan through the left BG shows
an empty groove. Note that the groove in this patient is shallow. The
biceps tendon (arrow) lies medially, anterior to the lesser tuberosity of
the humerus. A small amount of fluid is seen in the tendon sheath.

revealed; triangular bony depression (arrowed) in the postero superolateral aspect of
the humeral head with its base toward cutaneous surface (hill-Sachs lesion).

71. Synovial chondromatosis is a benign condition characterized by
synovial proliferation and metaplasia, with development of
cartilaginous or osteocartilaginous nodules within a joint, bursa
or tendon sheath. In the shoulder, synovial osteochondromatosis
may occur within the glenohumeral joint and its recesses
(including the tendon sheath of the biceps long head), and in the
subacromial-deltoid bursa. Such condition can be identified either
by radiography, ultrasonography or magnetic resonance imaging,
showing typical features according to each method. Radiography
commonly shows ring-shaped calcified cartilages and
periarticular soft tissues swelling with erosion of joint margins.
Ultrasonography demonstrates hypoechogenic cartilaginous
nodules with progressive increase in echogenicity as they become
calcified, with development of posterior acoustic shadow in case
of ossification. Besides identifying cartilaginous nodules,
magnetic resonance imaging can also demonstrate the degree of
synovial proliferation.

72. Secondary synovial osteochondromatosis. Sonographic study of the shoulder focusing the
tendon of the biceps long head (TBLH) on the transverse plane. Presence of synovial nodules
with different levels of echogenicity projecting toward the interior of the tendinous sheath,
easily identifiable by the presence of synovial fluid. The echogenicity depends on the
calcification degree, with hypoechoic nodules (black arrow) corresponding to noncalcified
chondromas, while calcified nodules present increased echogenicity (arrowhead).

73. Secondary osteochondromatosis. Sonographic study of the shoulder, focusing the tendon
sheath of the biceps long head on the longitudinal plane. The sheath is filled by fluid, and
in its interior calcified nodules with posterior acoustic shadow are identified (arrows).

74. Secondary synovial osteochondromatosis associated with supraspinatus tendinopathy. A:
Sonographic study of the shoulder focusing the tendon of the biceps long head on the
longitudinal plane, which is ruptured, with only its proximal stump being identified.
Multiple small synovial chondromas and effusion within the synovial sheath are observed.
B: Longitudinal section of the supraspinatus tendon. Thickened, hypoechoic and
heterogeneous tendon, with loss of fibrillar structure, characterizing tendinopathy process.
