Definitions
Fracture
A break in the structural continuity of bone (but we have to remember that there is always some degree of soft tissue injury with a fracture)
![Page 4: Fracture management -Basic](https://reader035.fdocuments.in/reader035/viewer/2022062418/555dd112d8b42aec698b53de/html5/thumbnails/4.jpg)
Goals of fracture treatment
• Prevent fracture and soft tissue complications
• Get fracture to heal and in satisfactory position for optimal functional recovery
• Intra-articular fracture needs accurate reduction & rigid fixation but non articular fracture of bone require anatomical reduction & stable fixation.
• Rehabilitate as early as possible by active & passive exercises.
• Restore patient to optimal functional state
![Page 5: Fracture management -Basic](https://reader035.fdocuments.in/reader035/viewer/2022062418/555dd112d8b42aec698b53de/html5/thumbnails/5.jpg)
How fracture happen
1. A single traumatic incident;
2. Repetitive stress;
3. Abnormal weakening of the bone (pathological fracture).
![Page 6: Fracture management -Basic](https://reader035.fdocuments.in/reader035/viewer/2022062418/555dd112d8b42aec698b53de/html5/thumbnails/6.jpg)
How fracture happen..
1. Twisting causes a spiral fracture;2. Compression causes a short oblique fracture;3. Bending results in fracture with a triangular
'butter-fly‘ fragment;4. Tension tends to break the bone transversely;

Types Of Bone Fracture (Anatomical over view)
![Page 8: Fracture management -Basic](https://reader035.fdocuments.in/reader035/viewer/2022062418/555dd112d8b42aec698b53de/html5/thumbnails/8.jpg)
Types of Fracture…cont.
• Open fracture :
When the bony fragments are exposed to external environment by means of wound
• Closed fracture :
The fracture fragments are not exposed to outside
![Page 9: Fracture management -Basic](https://reader035.fdocuments.in/reader035/viewer/2022062418/555dd112d8b42aec698b53de/html5/thumbnails/9.jpg)
Types Of Injury
High energy
Low energy
![Page 10: Fracture management -Basic](https://reader035.fdocuments.in/reader035/viewer/2022062418/555dd112d8b42aec698b53de/html5/thumbnails/10.jpg)
Open (compound) fractures
• Gustilo classificationType 1 – Low energy, wound <1cm (usually penetrating injury by bony fragments from inside )
Type 2 – Wound >1cm with moderate soft tissue damage
Type 3 – High energy wound >1cm with extensive soft tissue damage
Type 3A – Adequate soft tissue coverType 3B – extensive soft tissue
injury with external or internal degloving injury which needs flap coverage.
Type 3C – any open fracture associated with neuro-vascular injury.

Complications of fractures
• General complications– Shock– ARDS– Fat embolism– Head, chest, abdomen and pelvic
injuries– Crush syndrome– Tetanus– Gas gangrene– Infections – UTI, Chest– DVT/PE– Bed sores– Depression/PTSD
![Page 12: Fracture management -Basic](https://reader035.fdocuments.in/reader035/viewer/2022062418/555dd112d8b42aec698b53de/html5/thumbnails/12.jpg)
Complications of fractures
• Early– Visceral injury– Vascular injury– Compartment syndrome (later Volkmann
conctracture)– Nerve injury– Haemarthrosis– Infection
Late• Delayed union• Non-union• Mal-union• Tendon rupture• Myositis ossificans• Osteonecrosis• Algodystrophy• Osteoarthritis and
joint stiffness
![Page 13: Fracture management -Basic](https://reader035.fdocuments.in/reader035/viewer/2022062418/555dd112d8b42aec698b53de/html5/thumbnails/13.jpg)
Management of the injured patient
• Don’t treat the X-rays of the fracture, but treat the patient
• Life saving measures– Diagnose and treat life threatening
injuries (head injuries, Chest & abdominal injuries)
– Emergency orthopaedic involvement • Life saving• Complication saving
• Emergency orthopaedic management (day 1)
• Monitoring of fracture (days to weeks)• Rehabilitation and treatment of
complications (weeks to months)
![Page 14: Fracture management -Basic](https://reader035.fdocuments.in/reader035/viewer/2022062418/555dd112d8b42aec698b53de/html5/thumbnails/14.jpg)
Life saving measures• A= Airway and cervical
spine immobilisation• B = Breathing• C = Circulation
(treatment and diagnosis of cause)
• D = Disability (head injury)
• E = Exposure (musculo-skeletal injury)
![Page 15: Fracture management -Basic](https://reader035.fdocuments.in/reader035/viewer/2022062418/555dd112d8b42aec698b53de/html5/thumbnails/15.jpg)
Treatment principle of fracture
• Reduction• Maintain reduction (+ hold
until union)• Rehabilitate – restore function
by movement of the joint & patient itself.
• Prevent or treat complications
![Page 16: Fracture management -Basic](https://reader035.fdocuments.in/reader035/viewer/2022062418/555dd112d8b42aec698b53de/html5/thumbnails/16.jpg)
Open (compound) fractures
• High risk of infection• Can be associated with
gross soft tissue damage, severe haemorrhage or vascular injury
![Page 17: Fracture management -Basic](https://reader035.fdocuments.in/reader035/viewer/2022062418/555dd112d8b42aec698b53de/html5/thumbnails/17.jpg)
Open (compound) fractures - management
• While contacting orthopaedic team for definitive surgical treatment
• Irrigate wound with N.saline, if not available with tap water. Cover wound with sterile moist dressing.
• Immobilise limb preferable with external fixator if not possible , by pos. cast(including joint above & below)
• Remove obvious contaminants with meticulous effort
• Take photos• IV antibiotics (e.g. cefuroxime +/-
metronidazole or gentamicin)• Tetanus prophylaxis. • Check distal neurovascular status• Re-assess
![Page 18: Fracture management -Basic](https://reader035.fdocuments.in/reader035/viewer/2022062418/555dd112d8b42aec698b53de/html5/thumbnails/18.jpg)
Reduction
• If necessary, what reduction technique?
1) Closed reduction– Need anaesthesia/sedation, analgesia,
x-ray facilities, equipment, knowledge– Used for minimally displaced fractures
and most fractures of children• Distal part of limb pulled in line of
bone• Alignment adjusted in each plane
2) Open reduction– Above + theatre staff + additional
equipment– Risks
![Page 19: Fracture management -Basic](https://reader035.fdocuments.in/reader035/viewer/2022062418/555dd112d8b42aec698b53de/html5/thumbnails/19.jpg)
Maintain reduction• Necessary?
1) Relieve pain 2) Prevent mal-union –
nature heals the fracture, we keep it in a good position
3) Minimise non-union – maintenance of reduction should be continuous
![Page 20: Fracture management -Basic](https://reader035.fdocuments.in/reader035/viewer/2022062418/555dd112d8b42aec698b53de/html5/thumbnails/20.jpg)
Maintain reduction
• How?– 1) External method
• POP (+ equivalents), traction, external fixator
– 2) Internal method• Wires, pins, plates, nails,
screws
![Page 21: Fracture management -Basic](https://reader035.fdocuments.in/reader035/viewer/2022062418/555dd112d8b42aec698b53de/html5/thumbnails/21.jpg)
Maintain reduction – external method
• 1) POP
• Mould with palms– Adv – cheap,easy to
use, convenient, can be moulded
– Disadv – susceptibility to damage (disintegrates when wet), up to 48hrs to dry , difficulty to care of open wound
![Page 22: Fracture management -Basic](https://reader035.fdocuments.in/reader035/viewer/2022062418/555dd112d8b42aec698b53de/html5/thumbnails/22.jpg)
Maintain reduction–external method 2) Resin cast
• Adv – lighter and stronger, more resistant to damage, sets in 5-10mins, max strength in 30mins
• Disadvantage – cost, more difficult to apply/remove, more rigid with greater risk of complications eg. swelling and pressure necrosis
![Page 23: Fracture management -Basic](https://reader035.fdocuments.in/reader035/viewer/2022062418/555dd112d8b42aec698b53de/html5/thumbnails/23.jpg)
Maintain reduction – external method
• 3) Surface traction– Temporary measure
when operative fixation not available for awhile
– Skin can be injured if applied for long periods of time
– Neuro-vascular status should be checked during surface traction period
![Page 24: Fracture management -Basic](https://reader035.fdocuments.in/reader035/viewer/2022062418/555dd112d8b42aec698b53de/html5/thumbnails/24.jpg)
Maintain reduction – external method-
• 4) Skeletal traction– Requires invasive
procedure for longer term traction requiring heavier weights
– Complications associated with pin insertion eg. infection
![Page 25: Fracture management -Basic](https://reader035.fdocuments.in/reader035/viewer/2022062418/555dd112d8b42aec698b53de/html5/thumbnails/25.jpg)
Maintain reduction – external method-
• 5) External fixator• Indications
– Fractures associated with soft tissue injury
– Fracture associated with N/V damage
– Severely comminuted and unstable fracture
– Unstable pelvic fracture– Infected fracture– For skin graft & flap
coverage
• Complications– Pin track infection– Delayed union
![Page 26: Fracture management -Basic](https://reader035.fdocuments.in/reader035/viewer/2022062418/555dd112d8b42aec698b53de/html5/thumbnails/26.jpg)
Maintain reduction – internal method
• Advantages– Restoration of absolute anatomical state– Shorter hospital stay– Enables individuals to return to function
earlier• Indications
– Fractures that need operative fixation– Inherently unstable fractures prone to re-
displacement after reduction (eg. mid-shaft femoral fractures)
– Pathological fracture– Polytrauma (minimise ARDS)– Patients with nursing difficulties
(paraplegics, v. elderly, multiple trauma)
![Page 27: Fracture management -Basic](https://reader035.fdocuments.in/reader035/viewer/2022062418/555dd112d8b42aec698b53de/html5/thumbnails/27.jpg)
Maintain reduction – internal method
• By.. Nail , plate , screws, ware.
• Complications– Infection– Non-union– Implant failure– Re-fracture
![Page 28: Fracture management -Basic](https://reader035.fdocuments.in/reader035/viewer/2022062418/555dd112d8b42aec698b53de/html5/thumbnails/28.jpg)
Maintain reduction – internal method
• Wires & pins– Can be used in
conjunction with other forms of internal fixation
– Used to treat fractures of small bones
![Page 29: Fracture management -Basic](https://reader035.fdocuments.in/reader035/viewer/2022062418/555dd112d8b42aec698b53de/html5/thumbnails/29.jpg)
Maintain reduction – internal method
• Plates & screw– Extend along the
bone and screwed in place
– May be left in place or removed (in selected cases) after healing is complete
![Page 30: Fracture management -Basic](https://reader035.fdocuments.in/reader035/viewer/2022062418/555dd112d8b42aec698b53de/html5/thumbnails/30.jpg)
Maintain reduction – internal method
• Nail or rods– Held in place by
screws until the fracture is healed
– May be left in the bone after healing is completed
![Page 31: Fracture management -Basic](https://reader035.fdocuments.in/reader035/viewer/2022062418/555dd112d8b42aec698b53de/html5/thumbnails/31.jpg)
Stages of Fracture Healing
• Inflammation & Hematoma
• Callus Formation• Woven Bone• Remodeling
![Page 32: Fracture management -Basic](https://reader035.fdocuments.in/reader035/viewer/2022062418/555dd112d8b42aec698b53de/html5/thumbnails/32.jpg)
Types of fracture healing
• Primary : healing of the bone occur by interstitial growth of bone in rigid fixation by plate or nail
• Secondary : healing occurs with adequate callus formation both interstitial & surrounding, when micro movement occur in stable fixation by POP, cast, locking plate, external fixator.– Modern concept is …secondary
healing is preferable except intra-articular fracture
![Page 33: Fracture management -Basic](https://reader035.fdocuments.in/reader035/viewer/2022062418/555dd112d8b42aec698b53de/html5/thumbnails/33.jpg)
Factors Influencing Healing
• Age • Hormones • Functional activity• Nerve function• Nutrition • Drugs (NSAID)
Systemic Factors
![Page 34: Fracture management -Basic](https://reader035.fdocuments.in/reader035/viewer/2022062418/555dd112d8b42aec698b53de/html5/thumbnails/34.jpg)
Factors Influencing Healing…cont.
• Energy of trauma• Degree of bone loss• Vascular injury• Infection • Type of bone fractured• Degree of immobilization• Pathological condition
Local Factors
![Page 35: Fracture management -Basic](https://reader035.fdocuments.in/reader035/viewer/2022062418/555dd112d8b42aec698b53de/html5/thumbnails/35.jpg)
Fracture healing - operative
1) Reduction and compressionPrimary bone healingSlow process, rehabilitation rapid, high risk
2) Nailing or external fixationHealing by callusRapid process, rehabilitation rapid, lesser
risk
![Page 36: Fracture management -Basic](https://reader035.fdocuments.in/reader035/viewer/2022062418/555dd112d8b42aec698b53de/html5/thumbnails/36.jpg)
Healing Complications
• Delayed union• Nonunion• Malunion• Post -traumatic arthritis• Growth abnormalities• Fracture diseases- joint
stiffness, non-uses atrophy, Sudeck osteo-dystrophy,
![Page 37: Fracture management -Basic](https://reader035.fdocuments.in/reader035/viewer/2022062418/555dd112d8b42aec698b53de/html5/thumbnails/37.jpg)
Follow up of treatment by POP
• Judge each case on its own merits• Sticky – “Deformable but not
displaceable”• Union (weeks)
– Incomplete repair; Part moves as one; Local tenderness; Local pain on stress; See fracture line on-x-ray
• Consolidation (months)– Complete repair; No external
protection needed; Upper limb 6/52; Lower limb 12/52; Half for child; Double for transverse fractures
• Remodelling (years) successfully occur in growing skeleton .
![Page 38: Fracture management -Basic](https://reader035.fdocuments.in/reader035/viewer/2022062418/555dd112d8b42aec698b53de/html5/thumbnails/38.jpg)
Indications for operative treatment
– Current absolute indications:• Polytrauma; Displaced intra-articular
fractures• Open fractures with vascular injury or
compartment syndrome• Pathological fractures and non-union
– Current relative indications:• Loss of position with closed method;
Poor functional result with non-anatomical reduction; Displaced fractures with poor blood supply
![Page 39: Fracture management -Basic](https://reader035.fdocuments.in/reader035/viewer/2022062418/555dd112d8b42aec698b53de/html5/thumbnails/39.jpg)
Rehabilitation
• Restore the patient as close to pre-injury functional level as possible
• Rest, Elevation, Mobilisation (active/passive)
• Physiotherapy, • Work assessment and re-
employment
