4. Although bones are strong, they are susceptible to breaks
(fractures) all throughout life.
The most common times in life for fractures to occur are
during youth (due to excessive activity, sports, and bad
judgement) and in the elderly (due to bone thinning and
weakening, often due to osteoporosis).
5. Classification
On the basis of relationship with external environment
Closed :A fracture not communicating with the
external environment.
Open :A fracture with break in the overlying skin and
soft tissue, leading to the fracture communicating
with the external environment.
6. On the basis of aetiology
Traumatic
Pathological
On the basis of displacement
Undisplaced
Displaced
7. On the basis of pattern;
Transverse: The fracture line is perpendicular to
the long axis of the bone. Caused by bending
force.
Oblique: The fracture line is oblique. Caused by
a bending force which in addition has a
component along long axis.
Spiral: The fracture line runs spirally in more than
one plane . Caused by primarily twisting force.
8. Comminuted: Fracture with multiple
fragments. It is caused by a crushing or
compression force along the long axis of
the bone.
Segmental: There are two fractures in one
bone at different levels.
10. Types of Bone
Lamellar Bone
Collagen fibers arranged in parallel layers
Normal adult bone
Woven Bone (non-lamellar)
Randomly oriented collagen fibers
In adults, seen at sites of fracture healing,
tendon or ligament attachment and in
pathological conditions
11. Six most common types of
fractures:
1) Comminuted
2) Compression
3) Depressed
4) Impacted
5) Spiral
6) Greenstick
18. Stages of Fracture Healing
Stage of haematoma
Stage of granulation tissue
Stage of callus
Stage of remodelling
Stage of modelling.
19. How fractures heal – in nature
1) Reactive phase
Fracture and
inflammatory phase
Granulation tissue
formation
2) Reparative phase
Callus formation
Lamellar bone
deposition
3) Remodelling phase
Remodelling to
original bone contour
20. 1.) Inflammatory Phase
Bleeding from bone, bone periosteum, & tissues surrounding the
bone
formation of fracture hematoma & initiation of
inflammatory response
Induction (stimulus for bone regeneration) - caused
by:
decreased oxygen and bone necrosis (fractured bone
becomes hypoxic immediately)
disruption of & creation of new bioelectrical potentials
21. Inflammatory response - lasts between 2- 9 days
following injury:
phagocytes & lysosomes clear necrosed bone and other
debris
a fibrin mesh forms and “walls off” the fracture site
serves as “scaffold” for fibroblasts and capillary buds
capillaries grow into the hematoma
in a fracture, the new blood supply arises from
periosteum
normally 3/4 of blood flow in adult bone arises
from endosteum
in children, normal blood flow already comes
from periosteum.
22. 2.) Fibrocartilagenous callus Formation
Lasts an average of 3 weeks
Fibroblasts and osteoblasts arrive from periosteum &
endosteum
Within 2-3 days, fibroblasts produce collagen fibers that
span the break
23. This tissue is called Fibro - Cartilagenous Callus and
serves to “splint” the bone
FCC is formed both in and around the fracture site
Osteoblasts in outer layer of FCC begin to lay down new
hard bone
in a non-immobilized fracture, the FCC has poor
vascularization
24. 3.) Hard Bony Callus Formation & Ossification
Weeks to months
Fracture fragments are joined by collagen, cartilage, & then
immature bone
Osteoblasts form trabelcular bone along fracture periphery
(external callus)
Trabecular bone is then laid down in the fracture interior
(internal callus)
25. Ossification (mineralization) starts by 2-3 weeks &
continues for 3-4 months
Alkaline phosphatase is secreted by osteoblasts
blood serum levels serve as an indicator of the rate
of bone formation
In non-Immobilized fractures, more “cartilage” than
bone is laid down
this must later be replaced by normal cancellous
bone
results in a longer healing time and fractured area
remains weak for a longer period
Fractures should be reduced (immobilized) within 3-5
days
27. 4.) Bone Remodeling
Months to years (mechanically stable at 40 days)
Excess material inside bone shaft is replaced by
more compact bone
Final remodeled structure is influenced by optimal
bone stress
28. Woven bone is gradually converted to lamellar bone
Medullary cavity is reconstituted
Bone is restructured in response to stress and strain
(Wolff’s Law)
31. Healing in Bone:
1D - Hematoma
3D - Inflammation

Factors Inhibiting Bone Healing
37. Bone loss due to the severity of the
fracture
Infection
Inadequate immobilization (motion at the
fracture site)
Avascular Necrosis
39. Acute Compartment Syndrome
Serious condition in which increased
pressure within one or more compartments
causes massive compromise of circulation to
the area
Prevention of pressure buildup of blood or
fluid accumulation
Pathophysiologic changes sometimes
referred to as ischemia-edema cycle
40. Emergency Care - Acute
Compartment Syndrome
Within 4 to 6 hr after the onset of acute compartment
syndrome, neuromuscular damage is irreversible; the
limb can become useless within 24 to 48 hr.
Monitor compartment pressures.
Fasciotomy may be performed to relieve pressure.
Pack and dress the wound after fasciotomy.
41. Possible Results of Acute
Compartment Syndrome
Infection
Motor weakness
Volkmann’s contractures
Myoglobinuric renal failure, known as
rhabdomyolysis
42. Other Complications of Fractures
Shock
Fat embolism syndrome: serious complication resulting
from a fracture; fat globules are released from yellow
bone marrow into bloodstream
Venous thromboembolism
Infection
Ischemic necrosis
Fracture blisters, delayed union, nonunion, and
malunion
43. Muscle Atrophy, loss of muscle strength range of
motion, pressure ulcers, and other problems
associated with immobility
Embolism/Pneumonia/ARDS
TREATMENT – hydration, albumin, corticosteroids
Constipation/Anorexia
UTI
DVT
44. Musculoskeletal Assessment -

46. Special Assessment
Considerations
For fractures of the shoulder and upper arm,
assess client in sitting or standing position.

For distal areas of the arm, assess client in a
supine position.
For fracture of lower extremities and pelvis,
client is in supine position.
47. Risk for Peripheral
Neurovascular Dysfunction

bone cement is injected.
(Continued)
#43:Fat embolus – occur within 24 hours of injury 60% or within 48 hrs in 85%.
Patho FaT – fat molecules or globules are released from bone marrow enter into the blood. Fat in blood and urine but most experience –decrease in arterial Po2, increase Pco2, petechiae and altered mental state – mental confusion. P- 1934
#53:Traction – skin or skeletal
Countertraction – counteracts the pull of traction; Suspension – use of traction equipment, such as frames, splints, ropes, pulleys and weights- not pull suspends
Balanced suspension – allow patient to move freely and easy in bed.
Buck’s extension – common skin traction.
Skeletal - Kirschner wire or Steinmann pin , covered with cork or metal protectives, nurse applies small sterile dressings, cleaned, antibiotic oint. Check for infection
Balanced suspension with Thomas splint and Pearson attachment
#54:Elevate – control swelling
Keep cast dry- do not cover with plastic or rubber – cause condensation and become wet.
No weight bearing, report cracks or breaks to MD.
Use of stockinette or moleskin around edges of cast to prevent irritation.
Use proper medical devices, involve family and emotional support.
Avoid scratching the skin.
Blot the skin dry.
#61:Put Pt. On firm mattress
Ropes and pulleys should be aligned.
The pull should be in line with the long axis of the bone.
Any factor that might reduce the pull or alter it’s direction must be eliminated. Weighs should hang freely. Ropes should be unobstructed and not in contact with bed or equipment. Help the patient pull himself up in bed at frequent intervals.
Traction is not accomplished if knot in rope or footplate is touching the pulley or foot of bed or weight’s rest on floor.
Never remove the weights when repositioning the patient who is in skeletal traction because this will interrupt line of pull.
Every complaint of patient in traction should be investigated immediately.
