1. Fractures of the clavicle and scapula are uncommon but can result from high-energy trauma.
2. Clavicle fractures most commonly occur in the middle third and are usually treated conservatively with sling immobilization.
3. Scapula fractures involve the body, neck, glenoid, coracoid, or acromion and are often associated with life-threatening injuries requiring assessment by ATLS protocols. Most are also treated initially with sling immobilization.
2. CLAVICLE :
Is an S-shape long, curved ,tubular bone , lies horizontally
a cross the root of neck .
It articulate with sternum medially to form sternoclavicular
joint.
Also articulate with acromion process of scapula at
acromioclavicular joint and acromioclavicular ligament .
the muscles inserting on clavicle are : sternocleidomastoid,
And subclavius muscles .
The subclavian vessels and brachial plexus lie posterior to
clavicle .
6. Fractures of the clavicle:
common fracture in all ages
especially in children .
It is 2 – 10% of all fractures .
7.
8. Mechanism of injury :
Direct traumatic impact or fall on the shoulder 87% .
Direct impact to clavicle 07% .
Fall on outstretched hand 06% .
From fall on the side .
Vigorous muscle contraction , seizures [rare] .
Pathological fracture [rare] .
11. Allman classification : according to site of
fracture :
group 1: Fracture mostly occur in the
middle one third of clavicle 80% .
group 2: The fractures of outer third is 15% .
Fractures involving the acromioclavicular joint 28% .
group 3: fracture of inner [medial] third 5% .
12. Why does the fracture occur in middle
third more ?
It is the thinnest part of the bone .
It is the junction of the tow main curves of shaft .
Site of entrance of nutrient artery .
13.
14. common pattern of fractures of
clavicle are :
1 - Green stick fracture :
Common at the junction between
middle and outer third .
Common in children .
17. 4 - With greater displacement :
•There is over lapping and shortening .
18. Clinical presentation :
pain and tenderness at site of injury .
Obvious deformity and swelling sometimes
occur .
Patient come support his injured limb with other
hand and head tilted
toward injured side .
Local bruising .
19. vascular compilication are rare , but we must look
for it by : check pulse , gently palpate root of neck
.
Outer third # are easily missed for
acromioclavicular joint .
20. Diagnosis :
- Clinical picture examination .
investigation :
x-ray [AP view ] :
# is usually in middle third, outer fragment below
the inner .
#of outer third may be missed .
CT scan : useful for non union assessment .
arteriography : if vascular injury suspected .
21.
22. Treatment :
The aim is to provide support for the weight of the
arm .
Fracture of clavicle unite with or without treatment .
Healing occurs usually in 3-6 weeks .
It may be :
conservative or surgical .
23. Conservative treatment :
Support the arm in a sling until the pain subsides , usually 1-3
weeks .
Figure of 8- bandage .
Clavicle ring .
Analgesics .
24. Rehabilitation :
The patient should be instructed regarding hand
wrist and elbow exercises during immobilization .
And regarding shoulder exercises once fracture
healed .
25.
26.
27.
28. Surgical treatment :
Rarely indicated , except in :
- lateral one third fracture .
- presence of neurovascular injury .
- non union cases .
Internal fixation plate .
29.
30.
31. Complication:
late :
Malunion .
Ununion : treated by internal fixation and bone grafting .
Neurovascular injury [rare] . .
Stiffness of shoulder in elderly .
Ulnar neuropathy .
Refracture .
Early : [subclavian or carotid artery injury
,pneumothorax and hemothorax ,brachial injury ]
35. Scapula :
Is a flat triangular bone that lies on the posterior thorax wall
between 2-7 rib.
It envelope by :
supraspinatus muscle
infraspinatus muscle
subscapularis muscle
Attached to clavicle at acromioclavicular joint ,secured by
acromioclavicular ligament .
Articulate with humerus at glenohumeral joint .
Attached to thorax in scapulothoraxic joint .
36.
37.
38.
39. Fracture of scapula :
Fractures of scapula are uncommon because of
scapula location and surrounding muscles whitch
protect it .
-Fractures of scapula
are result of high energy
trauma with high incidence
Of associated injuries
by 60-98 % .
40. Associated life threatening injuries with scapula # :
pneumothorax
pulmonary contusion
arterial injury
abdominal injury
head injury
splenic or liver laceration
brachial plexus injury
41. Fractures of scapula are classified
according to location :
body fracture 50 % .
neck fracture 5-30 % .
glenoid fracture 10 % .
Coracoid fracture 8 % .
Acromion fracture 7 % .
42. Mechanism of injury :
# of body : from sever direct trauma
- fall from height with direct landing on posterior aspect of trunk .
- motor vehicle crush .
# of neck : direct blow to shoulder
- fall on shoulder .
- fall on outstretched hand .
# of glenoid : direct blow to lateral aspect of shoulder .
or impaction of humeral head in to glenoid fossa .
43. # of coracoid process :
direct blow or shoulder dislocation .
# of acromion :
direct down ward blow to shoulder .
45. Clinical picture :
-Brusing over scapula or chest area .
-Pain in movement .
-Swelling around back of shoulder .
-Tenderness at site of # .
Arm is held immobile .
46. Diagnosis :
After initial assessment , according to advanced trauma
life support [ATLS] principles , radiograghic evaluation is
indicated as soon as possible as patient stable .
X – ray :
Anteroposterior view lateral axillary view .
C T scan :is useful in glenoid or body # . .
47.
48.
49.
50. Treatment :
Reduction is usually unnecessary .
Patient wears a sling for comfort and from start
movement.
Check repeatedly for dislocation of the shoulder .
51. # of body by :
conservatively by analgesics and simple
sling to rest shoulder for 2-3 weeks .
# of acromion process :
Un displaced :
sling for 3-4 weeks for rest shoulder.
displaced :
acromion should be reduced and fixed .
52. # of coracoid :
conservatively in major , using a sling for 2-3
weeks.
Vigorous exercises should be prohibited for 2 m .
If there is marked displacement > open reduction .
# of neck and glenoid :
- sling for 2-3 weeks
- if there is displacement > shoulder spica after reduction .
- open reduction > indicated if there is isolated glenoid rim
fractures associated with dislocation or subluxation of
shoulder .

58. Complication :
Malunion non union > rare
Glenohumeral arthritis .
Limitation in range of motion .
After surgery :
local dyscomfort
infection
nerve injuries
post traumatic arthritis
rotator cuff dysfunction
59. Notes :
Scapular fracture should alert the surgeon to
presence of other injuries .
Sever chest injury should also raise suspicion
of possible scapular injury .
