Early reduction using Pemberton's osteotomy has been suggested for treating DDH
but no data on the long-term residual gait changes in such patients are available
in the literature. This study aimed to bridge the gap by performing quantitative
gait analysis on eleven females (age: 10.6 +/- 1.0 years) who were treated for
unilateral DDH using open reduction with Pemberton's osteotomy at 1.6 +/- 0.5
years of age, and eleven age-matched healthy controls. Walking at a normal speed,
the Pemberton group displayed significantly more anterior tilt, hiking at the
affected side and rotation towards the unaffected side of the pelvis, and more
knee flexion and ankle dorsiflexion in the affected limb. With this asymmetrical
gait, they appeared to reduce the demands on the hip flexors and abductors, and
knee extensors in the affected limb, which might have been involved during the
osteotomy, but increased compensatory efforts from the hip extensors, ankle
plantarflexors and knee flexors in the unaffected limb.
