bull The majority of children with bow legs befors age of 2 yrs and

knock knees presenting before 6 yrs will resolve spontaneously

Natural history

bull benign

bull selfcorrecting deformity

Correction devices (twister cables night splints shoe wedges)

are unnecessary

Anual clinical checks are recommended

Goal

bull Physiological deformities are best observed

bull Pathological deformities are treated surgically to achieve

straight legs at same length

Lower Limb Development

Torsional problems

bull usually not abnormal

bull developmental variation

bull resolves spontaneously

What conditions cause intoing

bull medial femoral torsion

bull medial tibial torsion

bull forefoot adduction

Each is contributing to the degree of intoeing

09042011

5

Lower Limb Development

Forefoot adduction

Adduction of the forefoot in respect to the hindfoot can cause intoing

Lower Limb Development

Femoral torsion

Definition angular difference between the axis

of the upper femur and that of the knee

Natural history

bull at birth the femoral torsion is 30deg

bull it decreases with growth and averages at 15deg for adults

From HEFTI

Kinderorthopaumldie

Springer-Verlag

Lower Limb Development

Increased femoral antetorsion

bull intoing gait pattern with kneeing in (patella pointing medially)

bull increased medial hip rotation decreased lateral hip rotation

Medial (internal) hip rotation Lateral (external) hip rotation

09042011

Lower Limb Development

Tibial torsion

of the tibia is rotated medially or laterally

Natural history

bull at birth the tibial torsion is 0deg

bull with growth it averages at 15deg - 20deg external rotation

From HEFTI

Kinderorthopaumldie

Springer-Verlag

Lower Limb Development

Increased medial tibial torsion

bull resolve spontaneously in 95 over time

bull often in combination with genua vara

Lower Limb Development

Torsional deformity

Age at presentation is important

bull early infancy usually due to metatarsus adductus

bull toddler age medial tibial torsion

bull early childhood medial femoral torsion

Lower Limb Development

Femoral and tibial torsional deformities

Treatment

bull the majority will resolve spontaneously over time

bull devices like twister cables night splints shoe wedges

and inserts are not effective

bull convince the family that observation is the best

Lower Limb Development

Tibial torsional deformities

Medial tibial torsion

bull mostly improves

bull if persistant supramalleolar derotation osteotomy

Leg Length Difference ndash LLD

Structural LLD

bull may occur at any site in the limb or pelvis

Tibial torsional deformities

Medial tibial torsion

bull mostly improves

bull if persistant supramalleolar derotation osteotomy

Lateral tibial torsion

bull increases with growth

bull more often requires operative treatment

Lower Limb Development

Femoral torsional deformities

Medial femoral torsion

bull normally improves

bull no risk of osteoarthritis

bull if persistant and severe rotational femoral osteotomy at the

proximal level in adolescence

Lateral femoral torsion (retrotorsion)

bull risk of osteoarthritis

bull requires operative treatment
