Introduction Introduction
• Fractures in children.
• Pathological fractures.
• Management techniques.
• Open fractures.
• Complications of injury.

Fracture in childrenFracture in children• Different from those in adults.
• Children's bones are more malleable, allowing a plastic type of "bowing" injury.
![Page 4: Principles Of Fractures(2)](https://reader036.vdocuments.net/reader036/viewer/2022062421/56812b34550346895d8f42af/html5/thumbnails/4.jpg)
Fracture in childrenFracture in children• The periosteum is thicker than in adults
and usually remains intact on one side of the fracture, which helps
1. stabilize any reduction, 2. decreases the amount of displacement,
and 3. lower incidence of open fractures in
children than in adults.
![Page 5: Principles Of Fractures(2)](https://reader036.vdocuments.net/reader036/viewer/2022062421/56812b34550346895d8f42af/html5/thumbnails/5.jpg)
Fracture in childrenFracture in children
• Healing is more rapid.
• Open reduction is rarely indicated.
• High remolding rate.
• Growth disturbance.
• Often missed (poor communication).
• X-rays of both limbs for comparison.

Physeal Injuries
• 30% of the fractures and occurred twice as often in the upper extremities as in the lower extremities.
• commonly used classification is that of Salter and Harris, which is based on the roentgenographic appearance of the fracture

Fracture in childrenFracture in children
Birth Fractures• These fractures occur most
commonly in the clavicle, humerus, hip, and femur.
• They rarely require surgery but frequently are diagnosed as pseudopalsy, infection, or dislocation.
![Page 10: Principles Of Fractures(2)](https://reader036.vdocuments.net/reader036/viewer/2022062421/56812b34550346895d8f42af/html5/thumbnails/10.jpg)
Fracture in childrenFracture in children Fractures Caused by Child Abuse • Mostly occurs between birth and 2 years of
age.
• Multiple fractures in different stages of healing are almost always indicative of child abuse.
• Multiple areas of large ecchymoses in different stages of resolution (from black and blue to brown and green) also are pathognomonic of child abuse.
![Page 11: Principles Of Fractures(2)](https://reader036.vdocuments.net/reader036/viewer/2022062421/56812b34550346895d8f42af/html5/thumbnails/11.jpg)
Fracture in childrenFracture in children
• The most common sites of fractures caused by child abuse are the humerus, tibia, and femur
• bone scan or a skeletal survey generally is indicated

Pathological FracturesPathological Fractures
• Break in the continuity of bone within an abnormal bone structure.
• Abnormal bone structure could be due to:
1- congenital diseases (O.I).
2- Infection (osteomyelitis).
3- Fracture through a cyst .
4- Metabolic diseases ( Osteoporosis, Osteomalacia, Pagets disease).

• Management:
• Aim: to make patient more functional and pain free for the remaining life span.
• Early operative stability should be carried out.
• Chemotherapy, Radiation, Hormonal.

I- Reduction – Methods:
• Should be Under Anesthesia• Closed or Open• Study X-Ray and direction of force• The basic Maneuvers : * Traction * Reverse mechanism of Inj * Direct pressure
![Page 24: Principles Of Fractures(2)](https://reader036.vdocuments.net/reader036/viewer/2022062421/56812b34550346895d8f42af/html5/thumbnails/24.jpg)

I- Reduction - Standards
• Anatomical Reduction is Ideal for all
• Anatomical Reduction is a MUST in :
* Dislocation * Intra-articular fractures * Fractures Both bones Forearm• X-Ray Image Intensifier help control reduction• Remember to Assess Reduction after 10 Days !
![Page 25: Principles Of Fractures(2)](https://reader036.vdocuments.net/reader036/viewer/2022062421/56812b34550346895d8f42af/html5/thumbnails/25.jpg)

Reduction Standards cont…• Reduction can be “Acceptable” if :-
* Alignment will NOT affect Function
* Remolding CAN correct deformity
• Remolding can correct :- *Angular NOT Rotational deformities *Children MORE than Adults

Management.Management.
I- Reduction - Timing• Immediate R. is a MUST in:
* Vascular Inj
* Spinal Cord or Nerve Inj• Urgent R. in OPEN fractures ; “Save Limb”• Dislocations Need Urgent reduction for Pain• CLOSED fractures CAN wait If Facilities do
not permit Urgent management

“Life is Movement, and
Movement is Life”
Do NOT Immobilize Any Joint Unnecessarily
