Fracture Definition
• Description: A fracture is a medical condition in which a bone is cracked or broken. While many fractures are the result of high force impact or stress, bone fracture can also occur as a result of certain medical conditions that weaken the bones.
![Page 3: FRACTURES And other Orthopaedic Disorders Jill Cavaiuolo.](https://reader036.fdocuments.net/reader036/viewer/2022062308/56649d985503460f94a81f5a/html5/thumbnails/3.jpg)
CLASSIFICATION OF #
Open fracture (Also called compound fracture.) - the bone exits and is visible through the skin, or a deep wound that
exposes the bone through the skin.
Closed fracture (Also called simple fracture.) - the bone is broken, but the skin is intact.
Complete- the bone is completely broken in two or more pieces
Incomplete-the bone is not broken all the way through

Categories of Fractures• In a compound fracture, also called an
open fracture, the bone breaks through the skin; it may then recede back into the wound and not be visible through the skin.
![Page 5: FRACTURES And other Orthopaedic Disorders Jill Cavaiuolo.](https://reader036.fdocuments.net/reader036/viewer/2022062308/56649d985503460f94a81f5a/html5/thumbnails/5.jpg)
Categories of Fractures• In a simple fracture, also called a closed
fracture, the bone breaks but there is no open wound in the skin.
![Page 6: FRACTURES And other Orthopaedic Disorders Jill Cavaiuolo.](https://reader036.fdocuments.net/reader036/viewer/2022062308/56649d985503460f94a81f5a/html5/thumbnails/6.jpg)
Categories of Fractures• Complete fractures
refer to the way the bone breaks: In a complete fracture, the bone snaps into two or more parts..(i.e. # ulna)
• Incomplete fractures have a bone that breaks, but does not go all the way through.

Common Fractures
Greenstick - incomplete fracture. The broken bone is not completely separated.
![Page 9: FRACTURES And other Orthopaedic Disorders Jill Cavaiuolo.](https://reader036.fdocuments.net/reader036/viewer/2022062308/56649d985503460f94a81f5a/html5/thumbnails/9.jpg)
Common Fractures
• Transverse - the break is in a straight line across the bone.
![Page 10: FRACTURES And other Orthopaedic Disorders Jill Cavaiuolo.](https://reader036.fdocuments.net/reader036/viewer/2022062308/56649d985503460f94a81f5a/html5/thumbnails/10.jpg)
Common Fractures
• Spiral - the break spirals around the bone; common in a twisting injury.
![Page 11: FRACTURES And other Orthopaedic Disorders Jill Cavaiuolo.](https://reader036.fdocuments.net/reader036/viewer/2022062308/56649d985503460f94a81f5a/html5/thumbnails/11.jpg)
Common Fractures
• Oblique - diagonal break across the bone.

Common Fractures
• Compression - the bone is crushed, causing the broken bone to be wider or flatter in appearance

Other types of Fractures
• An impacted fracture is one whose ends are driven into each other. This is commonly seen in arm fractures in children and is sometimes known as a buckle fracture.
• Other types of fractures are pathologic fracture, caused by a disease that weakens the bones, and stress fracture, a hairline crack.

Closed Oblique Fracture
• This fracture is considered to be mildly displaced.
![Page 17: FRACTURES And other Orthopaedic Disorders Jill Cavaiuolo.](https://reader036.fdocuments.net/reader036/viewer/2022062308/56649d985503460f94a81f5a/html5/thumbnails/17.jpg)
Types of Fractures• Mildly displaced spiral fractures of the
Tibia and Fibula.
![Page 18: FRACTURES And other Orthopaedic Disorders Jill Cavaiuolo.](https://reader036.fdocuments.net/reader036/viewer/2022062308/56649d985503460f94a81f5a/html5/thumbnails/18.jpg)
Types of Fractures
• Comminuted and mildly displaced fractures of the distal Tibia and Fibula.
![Page 19: FRACTURES And other Orthopaedic Disorders Jill Cavaiuolo.](https://reader036.fdocuments.net/reader036/viewer/2022062308/56649d985503460f94a81f5a/html5/thumbnails/19.jpg)
EXAMPLE: A 57 year old 350 lbs. man who puts
significant pressure on his ankle as he walks.
Diagnosis PILON FRACTURE
This is a comminuted fracture of the distal tibia due to axial compression
of the ankle joint. It is frequently associated with a fracture of the distal shaft of the fibula as well.

Fractures—Signs and Symptoms• Some clearly present (compound fracture)
or obvious deformity• Swelling, tenderness, altered sensation• Inability to move limb• Crepitus
– Grating sound heard if ends of bone fragments move over e/other
• Pain immediately after injury– Can be delayed if nerve damage in
area• Diagnostic Tests
– X-rays
![Page 32: FRACTURES And other Orthopaedic Disorders Jill Cavaiuolo.](https://reader036.fdocuments.net/reader036/viewer/2022062308/56649d985503460f94a81f5a/html5/thumbnails/32.jpg)
Fractures- Complications• Muscle spasm
– Due to local pain and irritation– Pulls bone fragments further out of
position– Causes angulation (deformity) and
rotation of bone which can cause more soft tissue damage, bleeding, and inflammation.
• Infections – Tetanus, osteomyelitis– In Compound fractures or when
surgery needed precautions taken (antimicrobials, tetanus booster shot)
![Page 33: FRACTURES And other Orthopaedic Disorders Jill Cavaiuolo.](https://reader036.fdocuments.net/reader036/viewer/2022062308/56649d985503460f94a81f5a/html5/thumbnails/33.jpg)
# Wrist: Note Swelling in top and bottom picture and deformity in the compound (open) fracture below.

Complications
• Ischaemia– Develops in limb following treatment– Occurs as oedema increases in 1st 48
hrs after trauma and casting.– Can be due to cast becoming too tight.
• The affected part becomes pale, pulseless, painful, paralysed, paraesthetic and 'perishing with cold' ('the 6 Ps').
• Fixed mottling of the skin implies irreversible changes.
• The limb may be red when dependent, leading to a misdiagnosis of inflammation, e.g. gout or cellulitis.
![Page 35: FRACTURES And other Orthopaedic Disorders Jill Cavaiuolo.](https://reader036.fdocuments.net/reader036/viewer/2022062308/56649d985503460f94a81f5a/html5/thumbnails/35.jpg)
Complications Cont.
Compartment syndrome:
– Develops shortly after fracture when more extensive inflammation (crush fractures)
– Increased pressure of fluid w/in fascia causes severe pain and ischemia or necrosis of muscle
– Pressure effects can be aggravated by cast
![Page 36: FRACTURES And other Orthopaedic Disorders Jill Cavaiuolo.](https://reader036.fdocuments.net/reader036/viewer/2022062308/56649d985503460f94a81f5a/html5/thumbnails/36.jpg)

Complications Cont.• Nerve damage
– w/ severe trauma or tearing of periosteum
• Failure to heal (nonunion) or healing of bone w/ deformity (malunion)– Results if bone is not stabilized with
ends closely approximated and aligned• Fractures at or near joint may have long-
term effects– Osteoarthritis or stunted growth
![Page 40: FRACTURES And other Orthopaedic Disorders Jill Cavaiuolo.](https://reader036.fdocuments.net/reader036/viewer/2022062308/56649d985503460f94a81f5a/html5/thumbnails/40.jpg)
Complications Cont.
• Fat emboli– Risk when fatty marrow escapes from bone
marrow into vein w/in 1st week after injury– More common in fracture of pelvis or long bones,
especially if not well immobilized after injury– Can travel to lungs and cause obstruction,
extensive inflammation, and respiratory distress
![Page 41: FRACTURES And other Orthopaedic Disorders Jill Cavaiuolo.](https://reader036.fdocuments.net/reader036/viewer/2022062308/56649d985503460f94a81f5a/html5/thumbnails/41.jpg)
Fat Embolism
• Fat Embolism Syndrome– Globules of fat, released from fractured
bone– Fat mixes with platelets
• Emboli travel to lungs, brain, or other areas.
– Clotting cascade activated = petechiae
![Page 42: FRACTURES And other Orthopaedic Disorders Jill Cavaiuolo.](https://reader036.fdocuments.net/reader036/viewer/2022062308/56649d985503460f94a81f5a/html5/thumbnails/42.jpg)
Fat Embolism Syndrome
• Signs and Symptoms– Dyspnoea– Confusion– Pulmonary complications
– Pulmonary Oedema– ARDS(Acute Respiratory distress
syndrome)– Petechiae-small spots on the skin

Closed Fracture Considerations• The energy of the
injury• Degree of
contamination• Patient factors• Additional injuries
![Page 45: FRACTURES And other Orthopaedic Disorders Jill Cavaiuolo.](https://reader036.fdocuments.net/reader036/viewer/2022062308/56649d985503460f94a81f5a/html5/thumbnails/45.jpg)
Fractures—Treatment • Management of Pain,nausea etc.• Cleaning the wound if open-may be done in
theatre• Immediate splinting and immobilization• Reduction of bones to restore normal
positionClosed reduction: exerting pressure and tractionOpen reduction: requires surgery
• Pins, rods, plates, screws
![Page 46: FRACTURES And other Orthopaedic Disorders Jill Cavaiuolo.](https://reader036.fdocuments.net/reader036/viewer/2022062308/56649d985503460f94a81f5a/html5/thumbnails/46.jpg)
Splinting and Immobilization
– Casting with plaster or fiberglass, and splints .
![Page 47: FRACTURES And other Orthopaedic Disorders Jill Cavaiuolo.](https://reader036.fdocuments.net/reader036/viewer/2022062308/56649d985503460f94a81f5a/html5/thumbnails/47.jpg)
Closed Reduction Traction
Application of force or weight pulling on limb that is opposed
by body weightForce maintains alignment of
bones, prevents muscle spasms, and immobilizes the
limb
![Page 48: FRACTURES And other Orthopaedic Disorders Jill Cavaiuolo.](https://reader036.fdocuments.net/reader036/viewer/2022062308/56649d985503460f94a81f5a/html5/thumbnails/48.jpg)
Open Reduction
• Internal fixation of Radius

External Fixation
• This is a patient treated with an external fixator, which is used to treat fractures that are too unstable for a cast. You can shower and use your hand gently with the external fixator in place.
![Page 50: FRACTURES And other Orthopaedic Disorders Jill Cavaiuolo.](https://reader036.fdocuments.net/reader036/viewer/2022062308/56649d985503460f94a81f5a/html5/thumbnails/50.jpg)

Fractures—Pathophysiology: Factors Affecting Healing Process
• Amount of local damage to bone and soft tissue– Major determining factor– Prolonged inflammation or extensive
damage to bv or periosteum impairs healing
• Amount of realignment and approximation– Closer the ends of the bones are, the
smaller the gap to fill, the faster the healing process
• Secondary problem – Foreign material or infection delays
healing
![Page 53: FRACTURES And other Orthopaedic Disorders Jill Cavaiuolo.](https://reader036.fdocuments.net/reader036/viewer/2022062308/56649d985503460f94a81f5a/html5/thumbnails/53.jpg)
Factors Affecting the Healing Process
• Numerous systemic factors– Delayed healing in elderly pts w/
circulatory problems, diabetes mellitus, anaemia, nutritional deficits, steroid therapy.
![Page 54: FRACTURES And other Orthopaedic Disorders Jill Cavaiuolo.](https://reader036.fdocuments.net/reader036/viewer/2022062308/56649d985503460f94a81f5a/html5/thumbnails/54.jpg)
Bone Healing• As soon as a fracture occurs, the body
acts to protect the injured area, forming a protective blood clot and callus or fibrous tissue.
• New "threads" of bone cells start to grow on both sides of the fracture line. These threads grow toward each other.
• The fracture closes and the callus is absorbed.
![Page 55: FRACTURES And other Orthopaedic Disorders Jill Cavaiuolo.](https://reader036.fdocuments.net/reader036/viewer/2022062308/56649d985503460f94a81f5a/html5/thumbnails/55.jpg)
Fractures—Pathophysiology of Bone Repair

Nursing Management
General Observations for pins, traction and casts include:
• Skin inspection hourly• Neurovascular observations ½ -1 hourly• Limb alignment• Limb exercises• Signs of infection –warmth, swelling, pain,
odour, discharge
![Page 57: FRACTURES And other Orthopaedic Disorders Jill Cavaiuolo.](https://reader036.fdocuments.net/reader036/viewer/2022062308/56649d985503460f94a81f5a/html5/thumbnails/57.jpg)
Nursing Management
• Elevation• Monitor Pt. pain and comfort• Remind Pt. of injured limb and positioning
etc.• Check bed positioning of Pt to ensure
traction is functioning.• Check equipment i.e. pulleys, pins etc.• Pts. with traction must never have weight
bags lifted randomly.
![Page 58: FRACTURES And other Orthopaedic Disorders Jill Cavaiuolo.](https://reader036.fdocuments.net/reader036/viewer/2022062308/56649d985503460f94a81f5a/html5/thumbnails/58.jpg)
Plaster Management
• Maintain cast integrity• Turn Pt. 1-2 hrly• Use palms when handling wet plaster• Do not cover wet cast-allow to dry• Check cast ooze and outline• Educate Pt. to not shove anything inside of
cast e.g. knitting needles
![Page 59: FRACTURES And other Orthopaedic Disorders Jill Cavaiuolo.](https://reader036.fdocuments.net/reader036/viewer/2022062308/56649d985503460f94a81f5a/html5/thumbnails/59.jpg)
Plaster Management
• Do not use blow dryer to dry cast• Cast will heat when drying• Cast is heavy• Observe skin around cast edge, skin
breaks can lead to infection

A Case History
A 24 year old right hand dominant man sustained a compound fracture of his right forearm as a teenager. He had a deep infection that required part of the bone to be removed. His right wrist was severely deformed and x rays showed bone loss and a non-union of the fracture.He had surgery that reconstructed his bone, rehab. and he returned to work as a full time construction worker.

Sprains and StrainsSprain. A sprain is a stretching or
tearing of ligaments. Ligaments are tough bands of fibrous tissue that
connect one bone to another. Common locations for sprains are
your ankles and knees. Strain. A strain is a stretching or
tearing of muscle or tendon. People commonly call strains "pulled" muscles. Hamstring and back injuries are among the most
common strains

Sprains and Strains• Both easily torn when excessive force exerted
on a joint• Avulsion
– Ligaments or tendons completely separated • Painful, tenderness, discoloration (due to
haematoma formation)• Strength and range of movement of the joint are
limited• Diagnosis: X-ray,scans etc. to rule out fracture
and to note extent of damage

Sprains and Strains Healing
• Tear, then inflammation, then granulation tissue
• Collage fibers form to create links w/ existing tissue
• Eventually healing mass bound together w/ fibrous tissue
• Healing 6 weeks• Severe damage requires surgery

Dislocation• Separation of 2 bones at a joint
– Loss of contact between articulating bone surfaces
– Usually one bone out of position, other normal– Eg. humerus displaced from scapula
• Subluxation– Bone only partially displaced w/ partial loss of
contact between surfaces• Causes considerable soft tissue damage
– Also damage to ligaments, nerves, bv as bone pulled away from joint
– Inflammation and bleeding– Severe pain, swelling, tenderness

Dislocation
• Diagnosis confirmed by X-ray• Treatment
– Reduction to dislocated bone, immobilization, therapy to maintain joint mobility
– Healing is slow if ligaments and soft tissue extensively damaged
