Lower extremity abnormalities in children

Area of Science:

• Pediatrics
• Orthopedics
• Developmental Biology

Background:

• Lower extremity abnormalities, including rotational (intoeing, out-toeing) and angular (bowlegs, knock-knees) problems, are frequent in children.
• Rotational issues stem from metatarsus adductus, internal tibial torsion, increased femoral anteversion, femoral retroversion, or external tibial torsion.

Purpose of the Study:

• To outline the diagnostic approach and management principles for common pediatric lower extremity rotational and angular abnormalities.
• To emphasize the importance of accurate diagnosis through physical examination and the torsional profile.

Main Methods:

• Diagnosis relies on a thorough patient history and physical examination.
• The torsional profile, a composite measurement of lower extremity components, is crucial for accurate assessment.
• Reference charts for normal values and deviations are utilized.

Main Results:

• Most lower extremity abnormalities in children improve spontaneously over time.
• Conservative management, including parental reassurance through explanation and serial measurements, is generally effective.
• Interventions like special shoes, casts, or braces demonstrate limited efficacy.

Conclusions:

• Accurate diagnosis of pediatric lower extremity abnormalities is achievable through careful clinical evaluation and the torsional profile.
• Conservative treatment and observation are the primary approaches, with surgery reserved for severe, persistent deformities.
• Understanding the natural history of these conditions is key to reassuring families and guiding management.
