Pediatric Orthopaedics
8
Developmental Stages
  • Infancy 0-18 months trust vs mistrust
  • Toddler 18mos 3 yrs autonomy vs shame/doubt
  • Pre-school 3-5 yrs initiative vs guilt
  • School age 6-12 yrs industry vs inferiority
  • Adolescence 13 20 yrs identity vs role
    confusion

9
Fractures in Children General
  • Overall higher incidence of fractures in children
  • Force required to break bone in child is less
    than adult
  • Physes (growth plate) are the weak link (ligament
    injury in adult, physeal fracture in child)
  • Bone healing much more rapid in children (femur
    fracture in neonate heals in 2-3 weeks, early
    childhood 4-6 weeks, and adult 16-20 weeks)
  • Much less likely to need operative fixation,
    greater remodeling of bone
  • Physeal fractures unique to children 20-25 of
    all fractures
  • Salter-Harris classification Based on fracture
    pattern

11
Fractures in Children General
  • Closed reduction and casting Most common
    treatment of pediatric fx
  • Thick periosteum of growing child aids in keeping
    the fracture reduced
  • Most pediatric fractures referred to pedi ortho
    specialist for definite management

12
Salter-Harris (SH) Classification
  • Fractures of growth plate divided into five
    categories based on pattern
  • I Fracture through the growth plate (very
    difficult to see on x-ray)
  • II Fracture through metaphysis into growth plate
  • III Fracture through epiphysis into growth plate
  • IV Fracture though epiphysis through growth
    plate and into metaphysis
  • V Crush injury to growth plate

13
ALWAYS RULE OUT NON-ACCIDENTAL TRAUMA!!

14
Trauma Child Abuse
  • 3.14 million children reported abused/year
  • Physical Abuse
  • Greatest lt 3 years (66-78)
  • 30 under 6 mos

15
Common Fractures Inflicted
  • Rib Fx. seen in 5-20 of abused
  • Scapular/ distal clavicle / ulna night stick fx
  • Vertebral fx. or subluxation
  • Bilateral, Multiple, or Different Stages of
    Healing
  • Corner fracture of tibia/femur

16
Multiple Rib Fractures Corner fx of Distal Tibia
17
Developmental Hip Dysplasia Introduction
  • No longer referred to congenital dislocation of
    hip
  • DDH is developmental (ongoing) process
  • Dysplasia refers to improper development or
    formation of acetabulum and/or femoral head
  • Incidence 1-5 per 1,000 newborns
  • From mild dysplasia to frank dislocation of hips

18
Developmental Hip Dysplasia Etiology
  • Exact cause unknown multifactorial
  • Risk factors for DDH
  • 1.) First-born children
  • 2.) Female sex (60-70)
  • 3.) Breech presentation (30-50)
  • 4.) Family History DDH
  • 5.) Prematurity
  • 6.) Other also associated with other ortho
    conditions Torticollis, foot deformities
    (calcaneovalgus), Trisomy 21 (increased laxity)

19
Developmental Hip Dysplasia Definitions
  • 60 affect left hip, 20 right, 20 bilateral
  • 25-30 present after newborn period (much harder
    to manage!)
  • Complete dislocation femoral head completely
    outside the acetabulum MUST be located prior to
    PAVLIK harness
  • Subluxation femoral head partially dislocated
  • Unstable femoral head can be pushed out from
    acetabulum with stress

20
Developmental Hip Dysplasia Examination
  • IMPERATIVE to assess hips during all well-child
    visits during first year!!
  • DDH detected by different signs based on infants
    age
  • Always examine each hip individually and then
    together to compare
  • NEWBORN EXAM
  • 1.) Barlows confirms instability. Attempt to
    gently displace the hip out of the socket over
    the posterior acetabulum

BARLOWs SIGN
21
Developmental Hip Dysplasia Examination
  • 2.) Ortolonis Confirms joint is reducible.
    Clunk sensation when thigh is abducted while
    lifting up the greated trochanter with the finger
  • Barlow and Ortoloni are much more reliable in
    neonates and infants up to 3-5 months
  • Make sure infant is relaxed and comfortable

ORTOLONIS SIGN
22
Developmental Hip Dysplasia
  • X-rays of pelvis not very useful until 4-6 months
    of age (femoral head not fully ossified)
  • Generally use ultrasound of hips to follow
    infants with DDH
  • Effectiveness depends on the skill and experience
    of person performing U/S

23
Developmental Hip Dysplasia Examination
  • Older Children Asymmetrical thigh/buttock skin
    folds
  • Limited abduction compare hips
  • Galeazzi Sign uneven knee heights when lying
    supine with knees flexed and soles of feet on
    table (indicates shortening)
  • Trendelenburg Gait often indicates weak hip
    abductors

LIMITED ABDUCTION
GALEAZZI SIGN
24
Positive Galeazzi Sign on Physical Exam
25
Developmental Hip Dysplasia Management
  • Refer to pediatric orthopaedics once diagnosis is
    confirmed
  • Ideal age for management 0-6 months
  • 60 of unstable hips will resolve spontaneously
    in 1st month
  • First line of treatment in infants 0-6 months
    PAVLIK harness
  • Harness should be properly fitted to avoid
    pitfalls in management

26
Correct Position of Pavlik Harness
27
Developmental Hip Dysplasia Management
  • Pavlik harness generally needed for 6-8 weeks
    allows hip to become stable
  • Monitor with U/S imaging every 2-4 weeks
  • If a dislocated hip has NOT reduced by 3-4 weeks
    STOP Pavlik harness and proceed with closed/open
    reduction with spica (body) cast
  • Toddlers and older children generally need
    operative treatment open reduction/ osteotomy

30
3 month old with DDH s/p Closed Reduction and
Spica Casting
  • Nursing Care Spica Cast
  • Neurovascular assessment
  • Support for parent/family (often need cast for
    prolonged time 3 months)
  • Keeping cast clean/dry
  • (positioning, diaper care)
  • Keeping the child a child (diversional activities
    based on age of child)

31
Talipes Equinvarus Clubfoot Deformity
  • Congenital deformity of the foot
  • Approx 1 in 1,000 births in U.S.
  • Multifactorial cause most often isolated and
    idiopathic
  • 2X more common in males
  • Bilateral in approx 50
  • Higher incidence assoc. with neurogenic
    conditions (spina bifida, cerebral palsy,
    arthrogryposis)

32
Talipes Equinovarus Clubfoot
  • Diagnosis usually obvious and made prenatally (18
    week U/S) or at birth
  • Three classic signs Fixed Plantar flexion
    (equinous of ankle)
  • Adduction (Varus), or turning in of
    heel/hindfoot
  • Supination, or turning under of
    forefoot/midfoot

33
Clubfoot Current Management
  • Treatment usually begins immediately after birth
  • Refer to pediatric orthopaedics as soon as
    diagnosis suspected
  • Overall goal is to correct clubfoot, maintain
    correction, facilitate normal growth and
    development
  • Current shift away from early surgical correction
  • Emphasis on early casting variable techniques
    used

34
Clubfoot General Management
  • Ponsetti approach Dr. Ignacio Ponsetti (U Iowa)
    pioneered
  • Serial manipulation and plaster casting of
    clubfoot
  • 4-5 Long Leg Plaster Casts applied weekly,
    Percutaneous heel cord tenotomy (cut achilles
    tendon) 85 patients
  • Splinting is essential part of management Denis
    Brown Abduction Brace (prevents recurrence)

35
Ponsetti Technique Used in Our Clinic
4 week old female with Bilateral Clubfoot
36
Denis-Brown Abduction Brace
  • Essential part of management in Ponsetti
    Technique
  • Worn full time (23 hours/day) for 1st two-three
    months after last cast removed, then at nighttime
    for 2-3 years
  • Done to avoid high rate of recurrence

37
Need regular follow-up in orthopaedics until end
of growth Children with Clubfoot usually do well
with treatment, develop normally, and participate
fully in athletics

39
Rotational Angular Deformities in Children
Introduction
  • Rotational and Angular Deformities are quite
    common in pediatrics
  • Very diverse spectrum of diagnoses physiologic
    to pathologic
  • In-toeing/Out-toeing, Genu varum (bowlegs)/valgum
    (knock-knees)

40
Causes of In-toeing Gait in Children
  • The most frequent causes of childhood in-toeing
  • Femoral anteversion
  • Medial Tibial Torsion
  • Metatarsus adductus

41
The In-Toeing Toddler/Child Assessment
  • Assess Femoral Version Measure external and
    internal rotation of the hips with the child
    prone and the knees flexed to 90 degrees. Assess
    both sides simultaneously. Internal rotation
    usually less than 65-70 degrees
  • If greater than 70 degrees in-toeing likely from
    femoral anteversion/femoral torsion
  • If rotation is asymmetrical, evaluate with AP of
    pelvis to r/o DDH or hip problem

42
Internal Femoral Torsion/Anteversion
  • In standing position, patellae will point inwards
    when feet are forward
  • Compensatory external rotation of tibia

43
Internal Femoral Torsion/Anteversion
  • Usually first seen in the 3-5 year age group,
    usually most severe b/w 4-6 years
  • Almost always symmetrical
  • More common in females approx. 2 1 ratio, often
    familial
  • Gait/running described as awkward/clumsy by
    parents

44
Femoral Anteversion Management
  • Gait is often worse when running or when fatigued
  • Children prefer the W sitting position because
    it is more comfortableshould not be discouraged
    or avoided
  • Reassurance and Observation!!
  • Special shoes, twister cables, etc avoided.no
    difference in outcome!!

45
Internal (Medial) Tibial Torsion
  • Toddler or young child often presents with c/o
    bowing legs
  • Usually symmetric in-toeing, if
    unilateral--usually worse on left
  • Often noticed when child is first starting to
    walk
  • With patellae facing forwards
  • (in neutral position), feet turn in

46
Measurement of Thigh Foot Angle Medial Tibial
Torsion
  • Quantitate Tibial Version
  • Thigh Foot Angle patient is pone, knees flexed
    90 degrees TFA is the angular difference between
    the axis of the foot and the axis of the thigh
  • Allow foot to fall into natural position, avoid
    manual positioning of foot
  • Medial Tibial Torsion Negative Thigh Foot Angle

47
Tibial Torsion
  • Resolves spontaneously in 95-98 of patients by
    age 4-6 years
  • Stretching, special shoes are inefffectivedoes
    not speed up resolution and makes no clinical
    difference
  • Can occasionally have mild persistence with no
    handicap or functional significance
  • Simple observation is best treatment and all that
    is needed

48
Metatarsus Adductus in Infants
  • Assess the foot for forefoot adductus
  • Lateral border of foot should be straight
  • Convexity of lateral border and forefoot
    adduction are features of metatarsus adductus

49
14 month old with Metatarsus Adductus
50
Metatarsus Adductus Management
  • Forefoot can gently be stretched passively with
    each diaper change
  • Occasionally will use serial casting and
    reverse/straight last shoes to correct deformity
  • Observation and Reassurance will resolve
    spontaneously in 95 of patients (tends to
    persist until age 12-18 months)

51
Lower Extremity Rotational Profile at Various Ages
  • Normal alignment progresses from 10-15 degrees of
    varus at birth to maximum valgus angulation of
    10-15 degrees at 3-4 years of age

52
Genu Valgum Assessment
  • Physiologic knock-knee deformity very common in
    children aged 3-5 years
  • Screening evaluation normal height and body
    proportions, symmetrical, localized or
    generalized, limb lengths equal
  • Measure rotational profile, measure
    intra-malleolar distance with the knees together
  • If generalized deformity, order metabolic
    screening labs

53
Pathologic Causes of Genu Valgum
  • Post-traumatic (most common)
  • Dysplasias
  • Primary tibial valga
  • Tumor
  • Infection
  • Rickets
  • Renal osteodystrophy
  • Congenital deficiency of fibula (fibular
    hemimelia)

54
Post-Traumatic Genu Valgum
  • Usually results from overgrowth following
    fracture of the proximal tibial metaphysis in
    early childhood
  • Valgus deformity develops during the 1st 12-18
    months post-injury due to tibial overgrowth
  • Management Most will correct spontaneously over
    course of years without operative treatment
  • If deformity persists osteotomy or
    hemiepiphyseodesis

55
Genu Valgum General Management
  • Age 2-6 years 97-98 will resolve spontaneously
  • If intermalleolar distance is gt 8-10 cm at age 10
  • 1.) Hemiephiphyseodesis of distal femur and/or
    proximal tibia
  • 2.) If skeletally mature a.) tibial varus
    osteotomy
  • b.)
    femoral osteotomy medial

56
Physiologic Genu Varum Assessment
  • Parents will often note bow leg deformity,
    usually recognized when child starts to walk
    (12-18 months)
  • Commonly bilateral and symmetric bowing
  • Seldom causes functional disability X-rays
    unnecessary until at least 18 months of age
  • Physiologic bowing usually spontaneously resolves
    by the age of two years

57
Infantile Blounts Disease Epidemiology
  • Risk factors Obesity, African American,Walking
    at early age, Family history
  • Differential Diagnosis Physiologic genu varum
    (metaphyseal-diaphyseal angle less than 15
    degrees)

  • Very difficult to differentiate from
    physiologic varus/
  • bowlegs in patients lt 2 years

58
Blounts Disease Radiographs
59
Adolescent Blounts Disease
  • Definition Growth disorder involving the medial
    portion of the proximal tibial growth plate that
    produces a localized varus deformity
  • More often unilateral, usually seen in obese
    individuals, slightly more males than females,
    African American, certain geographic regions
  • Definite cause unkown biomechanical overload to
    proximal tibia physis due to varus alignment and
    excessive body weight

60
Adolescent Blounts Disease Clinical Assessment
61
Leg Length Discrepancy
  • Congenital vs Acquired
  • Sx Short limb, Limp, back pain
  • Dx X-ray, CT, Bone Age

62
Leg Length Discrepancy Treatment
  • Mosely graph calculate age for epiphyseodesis
  • lt2cm LLD no treatment
  • 2-6 cm lifts, epiphysiodesis
  • gt6 - 15cm Shorten opp limb
  • Limb lengthening, External fixation, Spatial
    frames Ilizarov

63
Plan Management based on --Age of
Diagnosis --Severity --Projected Height at
Maturity Distal femur/prox tibia
physes Generally close at age 14 in Females and
16 in males
64
Leg Length Discrepancy External Fixation
  • Nursing Care
  • Pain Management
  • Pin Care Infection common
  • Compartment Syndrome
  • Provide Emotional Support

65
Legg-Calve Perthes Disease
  • Legg Calve Perthes disease (LCPD) is defined as
    an idiopathic avascular necrosis of the femoral
    head
  • Dr Legg, Calve, and Perthes independently
    researched and described a vascular injury to
    the hip in young children in 1910.

66
Early Concepts and Treatment
  • Early treatment concepts for LCPD was often quite
    severe
  • Involved bed rest, immobilization, long
    hospitalizations, special carts, slings, and
    braces

67
Epidemiology of LCPD
  • Affects about 1 in 10,000 children
  • Age of Onset age 2-12 with peak between age 4-8
  • Boys affected more often than girls (51 ratio)
  • More common among Asian and Central European
    populations
  • Short stature and delayed bone age are also risk
    factors

68
Etiology of LCPD
  • Blood flow to the femoral head is temporarily
    interrupted
  • Pathology is consistent with repeated bouts of
    infarctions and subsequent pathologic fractures
  • Subchondral fracture leads to avascular necrosis
    of the femoral head
  • Widening, flattening, and deformity---may
    partially or completely affect the femoral head

69
Radiograph of child with LCPD
70
Early Crescent Sign of Subchondral Fracture in
LCPD
71
Clinical Features of LCPD
  • Insidious onset
  • Most frequent symptom is painless limp
  • If pain is present, it is worse with activity and
    relieved by rest
  • Hip pain can ALWAYS refer to the knee
  • May also complain of anterior thigh or groin pain

72
Prognostic Factors of LCPD
  • Age is the Key to Prognosis younger
    patients have more growth remaining for
    remodeling/reshaping of femoral head
  • Age less than 6 years usually good outcome
    regardless of treatment
  • Greater than age 8-9 years often have poor
    prognosis requiring surgical correction
  • Containment Maintenance of ROM

73
Slipped Capital Femoral Epiphysis
  • SCFE is a displacement of the femoral head
    relative to the femoral neck which occurs through
    the physis (growth plate) of the femur
  • Considered one the few orthopaedic surgical
    emergencies/urgency
  • THE most common orthopaedic hip disorder
    affecting adolescents age range 9-16 years
  • Vast majority of patients are obese increased
    shear stress across the physis
  • Mean age at diagnosis Females12.0 years
  • Males13.5 years

74
Slipped Capital Femoral Epiphysis Etiology
  • Local Trauma 26 report
  • Mechanical forces obesity, decreased
    anteversion, oblique physis
  • Inflammation/synovitis
  • Endocrine imbalances
  • Heredity 5

75
Slipped Capital Femoral Epiphysis
  • Patients will often present with an antalgic limp
  • Lower limb often kept in external rotation while
    standing, decrease in internal rotation, flexion,
    and abduction of the hip when supine
  • Involved hip will often abduct and externally
    rotate with passive flexion

76
SCFE Management
  • Objective is to stabilize the growth plate to
    prevent further slippage and to avoid
    complications
  • Mild and Moderate stable slips In situ Pin
    Fixation (single screw)
  • Prevents further slippage and leads to fusion of
    the growth plate
  • If child lt 8 years fix with smooth pins to allow
    growth
  • Severe slips In situ Fixation, Osteotomy (neck,
    base of nech, intertrochanteric, subtrochanteric
    location of femur)

The Pediatric Spine Scoliosis
82
Scoliosis Classification
  • Idiopathic
  • Infantile (lt3 years)
  • Juvenile (3-10 years)
  • Adolescent (gt10 years) MOST COMMON
  • Congenital
  • Failure of formation
  • Failure of segmentation
  • Neural tissue disorders

83
Scoliosis Classification
  • Neuromuscular
  • Upper neuron (cerebral palsy)
  • Lower neuron (polio)
  • Myopathic (muscular dystrophy)
  • Secondary
  • Muscle spasm
  • Leg length discrepancy
  • Functional disorders

84
Scoliosis Examination of Spine
  • Note truncal symmetry
  • Note tenderness, defects, and cutaneous abnl. of
    the midline spine
  • Note difference in shoulder height, scapular
    prominence, flank crease, and pelvic symmetry
  • Perform the Adams forward bend test measure with
    scoliometer
  • Assess the sagitaal balance of the spine using
    plumb line

85
Adams Forward Bend Test
86
Adolescent Idiopathic Scoliosis
  • Prevalence 1-3 in general population
  • Curves measuring gt25 degrees 0.5 population
  • Female Male ratio 11 curves 6-10 degrees
  • 1.41 curves
    11-20 degrees
  • 5.4 1
    curves exceeding 21 degrees (no tx)
  • 7.2 1
    curves requiring orthopaedic intervention

87
Scoliosis Who Needs Treatment?
  • Two biggest factors to determine
  • 1.) Growth remaining
  • 2.) Curve magnitude
  • Treatment Options Observation, Bracing, Surgery

88
Remaining Growth Key to Management
  • Risk for progression
  • Risser Sign on Radiographs
  • Females Menarche status (very important)

89
Scoliosis Observation
  • Curves lt 25 degrees simple observation all that
    is needed
  • If skeletally immature generally follow-up
    radiograph and clinical exam every 6 months

90
Scoliosis Mangement Bracing
  • Growing patients (Risser 0,1,2) with
  • Curves that measure between 25-45 degrees
  • Cosmetically acceptable deformity
  • Compliance willing to wear the brace
  • Low profile Boston Brace most commonly used
  • Goals are the prevent curve progression and
    prevent the need for surgery

91
Scoliosis Boston Brace
  • Underarm TLSO, Low profile brace
  • Recommended 16-23 hour day wear, continued until
    growth is complete or if curve progresses to need
    surgery (45-50 degrees)
  • Goal is to prevent curve progression..does not
    eliminate curve that was there pre-bracing!

92
Scoliosis Surgical Management
  • Surgical indications
  • Curves that have progressed to 45-50 degrees
  • Goals are to stabilize spine and prevent
    continued progression
  • Gold standard posterior instrumented spinal
    fusion with autogenous bone graft (iliac crest,
    rib)

93
Posterior Instrumented Spinal Fusion
94
Osteogenesis Imperfecta OI
  • Brittle Bone disease fracture with minimal stress

  • Brittle baby NO BPs signs Dont pull limbs
  • Usually normal intelligence Physical NOT mental
    handicap
  • Encourage independence of child

97
Achondroplasia
  • Most common form of skeletal dysplasia, short
    stature, very shortened limbs
  • Rare 1 of every 26,000 live births MgtF
  • Disordered endochondral ossification
  • genetic defect autosomal dominant
  • 90 spontaneous mutations (75 born to normal
    parents)
  • Typical adult height Approximately 4 feet

98
Achondroplasia Clinical Spectrum
  • Hypotonia resulting in slow motor development
  • Can have joint contractures most common at elbow
  • Rhizomelia short proximal limbs with
    preservation of trunk length
  • Low back pain 2 to spinal stenosis (short
    pedicles)
  • Thoracolumbar kyphosis, Increased lumbar lordosis
  • Difficulty performing ADLs Maximize function

Questions Case Study
  • Anita is a 7 hour old Caucasian female born to a
    32-year-old gravida 1, para 1 mother. She was
    born by elective caesarean section at full term
    due to breech presentation. Her birth weight is
    8lb 1oz, with a length of 21 inches. Family and
    prenatal histories are entirely negative. Upon
    your initial observation, Anita is noted to be
    quiet, alert, and moving all extremities.
  • Which of the following would be MOST
    significantly increase Anitas risk of
    developmental dysplasia of the hip (DDH)?
  • 1.) Elective caesarian section
  • 2.) Breech presentation
  • 3.) Birth weight and length
  • 4.) Gravida 1, para 1 mother

118
Case Study DDH
  • Ortolani and Barlow techniques reveal a clunk
    on the left side and left hip abduction of 50

    entirely normal. While prone, Anitas gluteal
    skin folds are noted to be asymmetrical.
  • All the following statements regarding DDH are
    true EXCEPT
  • 1.) Routine radiographic studies are
    helpful in diagnosing DDH in

  • 2.) DDH is more common in female infants
    that in male infants
  • 3.) Diagnosis of DDH in the newborn is
    made primarily by PE
  • 4.) The etiology of DDH is often
    multifactorial

119
Case Study DDH
  • Anita is referred to pediatric orthopaedics for
    further evaluation and treatment. The goal of
    early detection and treatment of DDH is
  • 1.) To shorten the necessary course of
    treatment
  • 2.) To prevent avascular necrosis
  • 3.) To restore the articulation of the
    femur within the acetabulum
  • 4.) All of the above
  • The MOST likely management of DDH in the newborn
    would include
  • 1.) Observation of the newborns hip over
    a three month period
  • 2.) Traction with surgical reduction
  • 3.) Pavlik harness to maintain the hip in
    flexion and abduction
  • 4.) Triple diapering for 3 months

    require treatment and have
  • resolution with growth
  • C) Corrective shoes are required
  • D) Internal tibial torsion is
    frequently present

124
Questions
  • Mary is a 10 year old female who failed
    school screening for scoliosis and was found to
    have a 30 degree thoracic curve at her
    orthopaedic appointment. You know that treatment
    most likely will consist of
  • 1.) Simple observation with 6 month follow-up
  • 2.) Intense physical therapy
  • 3.) Full-time Boston Brace TLSO
  • 4.) Surgery Posterior spinal fusion

125
Questions
