Diagnosis of fracture
3. FRACTURE
i. Bones form the skeletal frame work of the body and
supports the body against gravity.
ii. It helps in movement and activities.
iii. Bones protect some body parts.
iv. Bone marrow produces blood products.
v. When outside forces are applied to bone it has the potential
to fail. Fractures occur when bone cannot withstand those
outside forces
4. Description of Location of #
• Which bone?
• Anatomic orientation
• E.g. proximal, distal, medial,
lateral, anterior, posterior
• Anatomic landmarks
• E.g. head, neck, body / shaft,
base, condyle
• Segment (long bones)
• Epiphysis, physis, metaphysis,
diaphysis

5. Description of Location of #
Segment (long bones)
•Epiphysis
•Physis
• Metaphysis
• Diaphysis
6. Signs or Symptoms of a Fracture
• Pain and tenderness
• Loss of function
• A wound (with bone sticking out)
• Deformity
• Unnatural movement
• Shock
• Swelling and bruising
7. Diagnosing Bone Fractures
• X-rays of injured area
• Some fractures are
difficult to see in an x-
ray, so a CT scan, MRI,
or other bone scans are
used
8. COMPLETE
• bone is completely
broken into 2 or more
fragments.
• -eg:
• transverse fracture
• oblique fracture
• spiral fracture
• impacted fracture
• comminuted fracture
• segmental fracture
INCOMPLETE
• bone is incompletely
divided and the
periosteum remains in
continuity.
• -eg:
• greenstick fracture
• torus fracture
• stress fracture
• compression
fracture.
Types of Fractures
11. Open Fractures
An open fracture is a broken bone
that penetrates the skin. This is an
important distinction because
when a broken bone penetrates
the skin there is a need for
immediate treatment, and an
operation is often required to clean
the area of the fracture.
The risk of infection, there are
more often problems associated
with healing when a fracture is
open to the skin.
12. Comminuted fracture
• Comminuted fracture - a
fracture in which the bone
breaks into more than two
fragments; usually caused
by severe forces
13. Spiral Fracture
• Fracture where at least one part of the bone has been twisted
Spiral fracture of femur
18. Compression Fractures
• Compression Fracture usually
occurs in the vertebrae.
• When the front portion of
vertebrae in the spine collapses
due to Osteoporosis which causes
bones to become brittle and
susceptible to fracture , with or
without trauma.
• An x-ray of the spine can reveal
the bone injury , however
sometimes a CT scan or MRI will
be used to insure that no damage
is done to the spinal cord.
19. Hairline Fracture
• A very thin crack or break in the bone
Hairline fracture of the foot
20. Stress Fracture
• Stress fracture - fracture without being
visibly broken; microscopic fissures in
bone that forms without any evidence
of injury to other tissues; caused by
repeated strenuous activity (ex:
running)
22. Depression Fracture
A depressed skull fracture is a break in a cranial
bone (or "crushed" portion of skull) with
depression of the bone in toward the brain.
The brain can be affected directly by damage to
the nervous system tissue and bleeding.
The brain can also be affected indirectly by
blood clots that form under the skull and then
compress the underlying brain tissue (subdural
or epidural hematoma).
23. Pathologic Fracture
• A type of fracture that is a
secondary result of another
illness or chronic condition
that weakens the bones of the
skeletal system
• The x-ray to the right shows
thinning of the femurs,
resulting in a fracture of the
proximal end of the right bone
• x-ray showing pathological
fracture right humorous due
to bone cyst
25. Fractures of Wrist
• Usually plain radiography is sufficient
• Ct and MR done to look for
– Subtle fractures not visualized on plain radiograph
– To look for intra-articular extension
– To look for soft tissue details especially MR
26. Colle`s and smith`s fracture
• Fig : -
Describe by : - Abraham Colle's - 1814.
It is not just fracture lower end of radius but
a fracture dislocation of the inferior
radioulnar joint .
Dorsal angulation
Occurs about 2.5 cm above the carpal
extremity of the radius .
A Smith's fracture, also sometimes known
as a reverse Colles' fracture is a fracture of
the distal radius. It is caused by a direct
blow to the dorsal forearm or falling onto
flexed wrists, as opposed to a Colles'
fracture which occurs as a result of falling
onto wrists in extension.
29. Scaphoid Fracture
• Left image: Plain x-ray. Normal appearances
• Middle Image: MRI (T1 scan) reveals an undisplaced fracture
through the waist of Scaphoid (arrow)
• Right Image: MRI (T2 with fat suppression) shows oedema in
the region of fracture (arrow)
31. Hook of the Hamate Imaging

hamate fracture (arrows)
32. ANKLE FRACTURE
• An x-ray showed a possible crack (circled), but it was far from definitive.
• An MRI showed a fracture (below, circled).
• A CT showed the crack clearly (below, circled),
33. Salter – Harris
I.– S = Slipped . Slipped growth plate
II.– A = Above . The fracture lies above the growth plate (metaphyseal)
III.– L = Lower . The fracture is lower than (below) the growth plate ( epiphyseal)
IV.– T = Through. The fracture through the growth plate including the
( metaphysis and epiphysis )
V.– R = Rammed . The growth plate has been rammed or ruined ( the physis
suffers a compression injury )
36. ANKLE FRACTURES
• Coronal (A) and sagittal (B) computed
tomography scans of a 13-year-old girl
who presented with right ankle pain and
swelling following a roller-skating
accident. Salter-Harris III injuries are
seen on both cuts, consistent with a
Tillaux fracture.
37. Salter Harris Fracture
• Axial computed tomography scan through the
physis showing a triplane fracture with the
posterolateral portion of the tibia hinged open
on the partially closed medial physis (A).
Coronal computed tomography scan showing
the anterolateral epiphyseal fragment attached
to the posterior metaphyseal spike (Salter III
fracture pattern) (B). Sagittal computed
tomography scan at the level of the fracture
seen in Figure 2B. This has the appearance of a
Salter II fracture pattern (C). Sagittal computed
tomography scan 1 slice medial to Figure 2C
showing the closed physis and intact
anteriomedial fragment attached to the distal
tibia. If the physis were open, this would be a
Salter IV fracture pattern (D).
38. Fractures of femur
• Careful examination of plain radiograph disclose many
information.
• CT has the advantage of complete detail of fractured
segments, there dislocation and relation to one another
39. Fractures of femur
• X-rays (top) revealing a
right-sided Pipkin IV
femoral head fracture and
associated Posterior Wall
acetabular fracture (yellow
arrows) and CT scan
images (bottom) further
delineating the fracture
patterns (femoral head
fracture is indicated with
grey arrows).
40. Fat Pad Sign and Joint effusion
• Normally on a lateral view of the elbow flexed in 90? a fat pad is seen
on the anterior aspect of the joint .
This is normal fat located in the joint capsule.
On the posterior side no fat pad is seen since the posterior fat is
located within the deep intercondylar fossa.
41. • If a positive fat pad sign is not present in a child, significant
intra-articular injury is unlikely.
• A visible fat pad sign without the demonstration of a fracture
should be regarded as an occult fracture.
42. Fat Pad Sign Pearls
• X-rays
– No visible fracture
– Positive fat pad sign
• Think occult fracture
– Kids: supracondylar fracture
– Adults: radial head fracture
43. Fractures of Knee joint

after a direct blow to the knee.

45. Tibial Plateau Fracture
Anteroposterior and lateral radiographs
revealing a tibial plateau fracture.
CT scan images further delineating the
fracture pattern and depressed bone
fragment.
46. Fracture of Tibia
• (a) CT scan before spanning external fixation - note the
difficulty in interpretation of the CT due to overlapping
femoral condyle.
• (b) CT scan after spanning external fixation - tibia is out to
length and femoral condyle does not interfere with the
interpretation of fracture configuration

radiographs showing an unreduced 3-part
head-splitting proximal humerus fracture
