Questions and Answers

In the context of pediatric flexible flatfoot, which of the following historical factors would MOST strongly suggest an underlying systemic etiology rather than a benign presentation?

  • Delayed achievement of gross motor milestones, coupled with a family history of connective tissue disorders. (correct)
  • Reports of generalized joint hypermobility and vague nocturnal lower extremity pain, improving with rest.
  • A history of pronated foot posture noted by parents since early childhood, with no recent changes.
  • Increased body mass index (BMI) percentile for age, without any other remarkable health concerns.

What subtle distinction in gait analysis MOST decisively differentiates a neuromuscular cause of pediatric flatfoot from a flexible flatfoot with primarily biomechanical etiology?

  • A marked Trendelenburg gait resulting in a noticeable drop of the pelvis on the swing phase.
  • Exaggerated hip circumduction during the swing phase of gait, indicative of potential lower extremity weakness.
  • An increased cadence with decreased step length, suggesting compensation for pain or instability.
  • Reduced arm swing contralateral to the stance limb, coupled with inconsistent STJ positioning throughout the gait cycle. (correct)

Which radiographic view is utilized to MOST comprehensively assess for the presence of a tarsal coalition as a contributing factor to rigid pediatric flatfoot?

  • A dorsoplantar radiograph of the foot with internal oblique views.
  • A weight-bearing anteroposterior radiograph of the foot combined with a lateral view of the ankle joint.
  • A weight-bearing lateral radiograph of the foot, complemented by Saltzman views.
  • A Harris-Beath view of the calcaneus alongside Broden's views of the subtalar joint. (correct)

Explain the biomechanical rationale for utilizing an Evans calcaneal osteotomy in the surgical correction of pediatric flexible flatfoot, detailing how it affects the alignment of the foot and ankle complex.

<p>The Evans calcaneal osteotomy lengthens the lateral column of the foot, which helps correct abduction at the midtarsal joint. This shifts the ground reaction force medially, increasing the mechanical advantage of the posterior tibial tendon and reducing pronation.</p> Signup and view all the answers

Explain the role of the Windlass mechanism in maintaining the medial longitudinal arch of the foot, and how it is affected in pediatric flexible flatfoot.

<p>During the toe-off phase of gait, dorsiflexion of the hallux causes tension in the plantar fascia, which approximates the calcaneus and metatarsal heads, thus elevating the medial longitudinal arch. In pediatric flexible flatfoot, this mechanism is often compromised due to hypermobility, weakness, or structural anomalies.</p> Signup and view all the answers

Study Notes

Pediatric Flexible Flatfoot Objectives

  • Identify clinical evaluations of pes planus in pediatric patients
  • Show how to tell the difference between rigid and flexible deformities
  • Identify the causes of pes planus in pediatric patients
  • Understanding flatfoot treatments, both surgical and nonsurgical, in children

Infants and Flatfoot

  • Most babies are born with flatfoot
  • Normal arches typically develop between 7 and 10 years old

Foot Shape

  • Foot shape is dynamic during development
  • Study shows the natural history of feet in preschool children impacts:
    • Decreased flexible flatfoot rate, the severity of flatfoot
  • Moderate to severe flatfeet reported:
    • 57% at age 2 to 3
    • 21% at age 5 to 6

Pediatric Flatfoot Diagnostic Chart

  • Key historic elements include age of onset, family history, related conditions, symptoms, trauma, activity level, past treatments
  • Key findings on examination include appearance during weight bearing and non-weight bearing, range of motion, areas of tenderness, gait
  • Diagnostic studies that can be used include radiographs, CT scans, MRI, bone scans, and lab tests

Pediatric Flatfoot Types

  • Flexible flatfoot
  • Rigid flatfoot
  • Skewfoot
  • Other etiologies

Rigid Flatfoot Considerations

  • Congenital vertical talus
  • Tarsal coalition
  • Peroneal spastic flatfoot w/o coalition
  • Iatrogenic and post-traumatic causes

Other Etiologies of Flatfoot

  • Neurologic, Muscular, Genetic, Syndromes, Collagen disorders

Pediatric Flexible Flatfoot Diagnostic/Treatment Chart

  • Start with significant history: low back, knee, or heel pain, age, comorbidities, family history, systems review
  • Radiographic findings could include angular changes or peritalar subluxation
  • Significant findings during examination could include gait disturbances, prominent talar head, or tight heel cord
  • Diagnosis can distinguish between physiologic and non-physiologic flatfoot

Physiologic Flatfoot

  • Observation with patient education

Non-Physiologic Flatfoot

  • If asymptomatic, continue observation
  • If symptomatic, initial treatment options: -Activity modification -Orthoses -Stretching -NSAIDS -If symptoms continue consider surgical options

History of Present Illness

  • Aim to identify the specific concern, person concerned, manifestation onset, duration, if improving or worsening

Medical and Developmental History

  • Medical history to include milestones, developmental delays, birth complications
  • Developmental milestones: Gross motor skills, fine motor skills, language, social skills

Size and Gender

  • Increase in size increases the risk of flatfoot
  • Flatfoot occurs more commonly in boys

Flexible Flatfoot Facts

  • 15-20% of adults have flexible pes planus (most asymptomatic)
  • Risk factors include being overweight, male, having equinus, and hypermobility syndromes

Hypermobility Syndromes

  • Marfan
  • Ehlers-Danlos
  • Benign Hypermobility

The Work Up Considerations

  • Sagittal Plane: Equinus, Hamstring, Iliopsoas
  • Frontal Plane: Genuvalgum, Forefoot varus, Limb length discrepancy
  • Transverse Plane: Femoral antetorsion, Internal femoral position, Internal tibial torsion

Physical Exam Considerations

  • Gait analysis: Examine normal, antalgic, and neuromuscular movements
  • Note line of progression and STJ position
  • Examine tip toe and heel walk
  • Note any shoulder drop

Physical Exam - Leg and Knee Position

  • Genu valgum (knock knees)
  • Genu varum (bow-leggedness)

Physical Exam - Foot position

  • “Too many toes” sign

Heel Raise Observation

  • Note flexibility of the foot

Equinus relationship

  • Equinus can be related to midfoot hypermobility

Jack’s Test/ Hubscher Maneuver

  • Test used to assess the flexibility of the arch

Windlass Mechanism

  • Refers to the tightening of the plantar fascia with dorsiflexion of the toes

Radiographic Findings

  • Radiographic films can reveal angular changes and peritalar subluxation

Flexible Flatfoot - Nonsurgical Treatment

  • Orthotics
  • Ankle Foot Orthosis (AFO)
  • Physical therapy
  • Dynamic stretching device/brace

Flexible Flatfoot - Surgical Treatment

  • Arthroeresis
  • Calcaneal osteotomy
  • Evans
  • Medial displacement
  • Medial column osteotomy
  • Arthrodesis
  • Deforming Factors
  • Kidner
  • Gastrocnemius recession

Symptomatic Pathologic Flatfoot

  • Surgical options: Osteotomy, Arthroeresis, Fusions, Soft Tissue

Calcaneal Osteotomy - Evans

  • Surgical procedure for correcting flatfoot

Accessory Navicular

  • First described in 1605 by Bauhin
  • Von Lushka (1858) described it in 17 yr old
  • Tarsal scaphoid & accessory ossicle joint appear linked and bound by capsule

Accessory Navicular - Other Names

  • Accessory scaphoid
  • Pre-hallux
  • Os tibiale externum
  • Os naviculare secundarium
  • Navicular secundum
  • Gorilloid navicular
  • Kidner Foot

Accessory Navicular - Incidence & Development

  • Incidence is between 2-21%
  • About half of cases will fuse
  • Present in 2nd fetal month
  • Ossifies ~ 9-11 years old
  • More common in women than men
  • Bilateral in 50-90% of cases

Accessory Navicular - Types

  • Type I (30%) - Separate
  • Type II (50-60%) - Synchondrosis
  • Type III (10-20%) - Fusion

Accessory Navicular - Non-Surgical Treatment

  • Relieve pressure
  • NSAIDs
  • Shoe Modification
  • Orthotic
  • Short Leg walking cast

Accessory Navicular - Surgical Treatment

  • Kidner (1929)
  • Excision and reattachment of PT tendon
  • Open Reduction Internal Fixation (ORIF) for accessory bone
  • Percutaneous drilling

Accessory Navicular - Treatment of Comorbidities

  • Flexible flatfoot and Equinus
