Objectives 1.  Introduction of most common pediatric

orthopedic injuries 2.  Understand physiologic differences between

adult and pediatric musculoskeletal system 3.  Introduction of orthopedic injuries unique to

pediatrics 4.  Discussion of initial evaluation and

management of common pediatric orthopedic injuries

Introduction nn Children experience diverse array of illnesses and Children experience diverse array of illnesses and

injuriesinjuriesnn Many unique to pediatricsMany unique to pediatricsnn 1/3 of all ED patients annually are children 1/3 of all ED patients annually are children (Annals of Emergency (Annals of Emergency

Medicine, 1990)Medicine, 1990)

nn PrePre--hospital setting, 10% ambulance runs are for hospital setting, 10% ambulance runs are for pediatric patientspediatric patients ((KallsenKallsen GW, in GW, in DieckermanDieckerman RA, 1991)RA, 1991)

nn Trauma represents majority of pediatric transports Trauma represents majority of pediatric transports (50(50--65%)65%)

nn Age dependentAge dependentnn Injuries are most common reason pediatric patients Injuries are most common reason pediatric patients

present to the EDpresent to the ED

5

Introduction Ø Represent 10-15% of ED visits Ø 70% related to falls in younger children Ø  In the multi- trauma patient, > 50% will

have at least 1 musculoskeletal injury Ø  Injury patterns in pediatrics differ greatly

from adults Ø Recognizing and understanding these

differences critical to appropriate diagnosis and care

6

Pediatrics nn Prehospital providers often have:Prehospital providers often have:

–– Limited pediatric patient contactsLimited pediatric patient contacts–– Limited knowledge, training, and Limited knowledge, training, and

experience specifically directed towards experience specifically directed towards pediatricspediatrics

nn Many other healthcare providers are Many other healthcare providers are similarly affectedsimilarly affected

nn Children are not little adults!!!Children are not little adults!!!7

Pediatric Trauma

Ø Distinguished from that in adults by differences:

1. mechanisms of injury 2. fracture patterns 3. multiple acceptable treatment options 4. associated systems injuries 5. mortality in pediatric polytrauma 6. residual morbidity

Common Pediatric Mechanisms of Injury

Ø Pedestrian struck by vehicle Ø Fall from low heights Ø Non accidental injury in infant/ toddler Ø Power tools/ lawn mower injuries Ø Vehicle operator and falls from heights

Mechanisms of Pediatric Injury

PMcM, Liftarm, Wikimedia Commons 11

Non accidental Injury Ø  Close to 1% all children victims of abuse Ø  1/3 of these kids will be reinjured Ø  1-5% of these kids will die if returned to original

environment Ø  Abuse is 2nd leading cause of death infants and children Ø  Majority < 1 year of age Ø  Must have high index of suspicion Ø  Risk factors: parental substance abuse young parent child < 3 yrs old premature disability

12

Non accidental Trauma History - what is mechanism - is story plausible - who witnessed event - time from injury to tx - who has access to pt - inconsistent stories

Physical Exam -  serious injury can

exist despite no outward signs

-  patterns of bruising/ unexpected areas

-  burns/ scars -  May require opthy

exam/ CT scan (Shaken Baby)

13

Orthopedic injuries in Non accidental Trauma

Ø  Seen 30-50% children Ø  Injuries highly specific for abuse

include: - corner or bucket handle fractures - scapular fractures - posterior rib fractures - old fractures - multiple fractures of different ages - spinous process fractures Ø  Spiral fractures are not

pathognomonic for abuse

Physiologic Differences in Child

Ø  Periosteum thicker and stronger

Ø  Bone more porous Ø  Higher incidence of plastic

deformities Ø  Less ligament injury/

dislocation Ø  Remodeling is extensive Ø  15% childhood fractures

involve growth plate Ø  Radiographic evaluation

more difficult due to growth plates

Ø  Kids do stupid things!

Pediatric Musculoskeletal System Ø  Pediatric skeleton less densely

calcified than adult Ø  Composed higher percentage of

cartilage Ø  Bones are lighter and more porous Ø  More porous= more pliableà less strengthà increase fractures Ø  Actively growing structure: - long bones contain growth plates/ physes - end of bones contain epiphysis Ø  Bones of child surrounded by thick and

active periosteum Ø  Ligaments and periosteum stronger

than bone itselfà - physis is weak link - fractures more common than sprains Ø  Response to trauma age dependent

What’s Your Diagnosis?

15 year old baseball player Rounding 3rd base, acute pain in hip while

running Pain is sharp, felt “ pop” Finished game but has pain walking Exam benign except pinpoint tenderness at

AIIS, worse w/ abduction of hip

41

Avulsion Fracture of the Pelvis

Ø  Intense muscular contraction

Ø  Subsequent shearing of secondary ossification center

Ø  Pelvis, tibia tubercle, phalanges

Ø  Require conservative care

Ø  Adolescent -14-18 yrs Ø  90% Male Ø  80% sports related


Initial Approach to Orthopedic Trauma

Ø  ABC’s Ø  Evaluate involved limb for: - neurovascular compromise - open vs closed fracture - compartment syndrome Ø  Evaluate for fx’s at increased risk for significant bleeding/

hemodynamic instability ( pelvic/ femur fractures) Ø  Search for associated injuries Ø  Pain control Ø  Immobilization Ø  Xray evaluation Ø  Miscellaneous: last meal, allergies/ meds, last period if

female 43

Fracture Treatment in Children: General Principles

Ø  Children heal faster than adults Ø  Require less immobilization time Ø  Stiffness of adjacent joints less likely Ø  Vast majority- tx’d closed methods Ø  Exceptions: open fractures Salter Harris type III- IV injury multi-system trauma Ø  If any concern re: displacementà keep NPO Ø  Any swollen elbow is displaced supracondylar fx until

proven otherwise Ø  Analgesia ( morphine 0.1 mg/kg IV), then Xrays

44

Radiographic Evaluation

Ø  Point tenderness Ø  Large amount of swelling Ø  Severe pain Ø  Persistent symptoms after 3-5 days Ø  High risk mechanism Ø  Must include joint above and below Ø  Comparison views? Ø  All unstable and deformed fractures must be

immobilized prior to transfer to radiology

45

What Does Ortho Need to Know? Ø  Age and sex of patient Ø  Mechanism of injury Ø  Bone or bones involved in

injury Ø  Type of fracture Ø  Neurovascular status of the

extremity Ø  Presence and amount of

displacement Ø  Presence and estimate of

angulation Ø  Open or closed fracture

Splinting Controversies Ø  Cast vs Splint Plint AC, Perry JJ, et al (Pediatrics, March 2006) Children’s Hospital Ottawa, Canada Kids w/ removable splint for buckle fx wrist : 1. better physical function 2. less difficulties ADL Ø  Cast vs Brace Boutis K, Willan AR, et al ( Pediatrics, June 2007) Hospital For Sick Children, Toronto, Canada Removable ankle brace better than casting for some ankle injuries: 1. isolated low risk ankle fractures 2. Greater proportion in aircast/ braced group returned to baseline activities at 4 weeks 3. Greater parental and child satisfaction 108

NSAIDS and Bone Healing Ø  Controversial in orthopedic world Ø  Delayed healing long bones retrospective animal studies Ø  Prospective human studies ( only 2) inconclusive Ø  No pediatric studies Ø  Ibuprofen much better analgesia than Tylenol or Codeine for

fractures ( Clark EC, et al, Pediatrics March 2007) Ø  Ibuprofen provides analgesia equivalent to acetaminophen-

codeine in the treatment of acute pain in children with extremity injuries: a randomized clinical trial. (Friday JH, Kanegaye JT, McCaslin I, Zheng A, Harley JR, Acad Emerg Med. 2009 Aug;16(8):711-6 ).

Conclusions Ø  Kids are not little adults Ø  Think about mechanisms of injury Ø  Injuries must correspond to history, exam,

developmental level of the child Ø  Non accidental trauma may be manifested by orthopedic/

extremity injury Ø  Don’t be distracted by the obvious- look and treat life

threatening injuries Ø  Be kind and control a child’s pain Ø  Fractures may not always be seen on initial films and

can be very subtle Ø  Think “ fracture” before sprain Ø  When in doubt, SPLINT!! Ø  Early diagnosis and treatment septic arthritis essential 110
