Background: Intoeing is a frequent gait problem in children with
cerebral palsy. It is essential to determine the cause(s) of intoeing when
surgical intervention is being planned. The purpose of this study was to
evaluate the prevalence of various causes of intoeing in children with
cerebral palsy and to determine whether the causes differ between children
with bilateral and those with unilateral involvement.
Methods: The cause of intoeing gait was examined retrospectively,
with use of gait analysis, in 412 children with cerebral palsy (587 involved
sides). The causes were evaluated separately for the children with bilateral
involvement (diplegia or quadriplegia) and those with hemiplegia.
Results: Overall, the most common causes of intoeing were internal
hip rotation (322 of 587 sides) and internal tibial torsion (296 of 587
sides). Pes varus contributed to intoeing of thirty-five of the eighty-two
involved limbs of the patients with hemiplegia and of forty-two of the 505
limbs of the patients with diplegia or quadriplegia. Multiple causes of
intoeing were noted in 215 of the 587 involved limbs, including 176 of the 505
limbs of the patients with bilateral involvement and thirty-nine of the
eighty-two involved limbs of the patients with hemiplegia. The most common
causes of intoeing in the subjects with bilateral involvement were internal
hip rotation (288 of 505), internal tibial torsion (261 of 505), and internal
pelvic rotation (ninety-two of 505). The most common causes in the hemiplegic
children were internal tibial torsion (thirty-five of eighty-two), pes varus
(thirty-five of eighty-two), internal hip rotation (thirty-four of
eighty-two), and metatarsus adductus (twenty of eighty-two).
Conclusions: More than one-third of children with cerebral palsy
have multiple causes of intoeing. Pes varus commonly contributes to intoeing
by children with hemiplegic cerebral palsy but rarely contributes to intoeing
by those with diplegia or quadriplegia. These findings should be carefully
considered prior to surgical correction of the intoeing gait of these
patients.
