Background: Rotational profiles vary widely among healthy children. Rotation of the long bones refers to the twist of the bone about its long axis. Rotational deformity of the lower limb in the transverse plane is associated with many clinical settings ranging from harmless to excessive intoeing in children. Materials and Methods: This study was conducted at the Department of Orthopedics, Indraprastha Apollo Hospital, New Delhi. Children presenting to the outpatient department during the period of April to September 2013 were followed up. It is a prospective study conducted over 14 months. A total of 27 children (54 lower limbs) were included and followed up. Results: Twenty-seven children were selected as per the inclusion criteria and assessed for the thigh-transmalleolar axis, thigh-foot angle, femoral anteversion (FA), foot progression angles (FPA), and hip rotations at 4-month interval for 2 follow-ups. There were very few studies of such type which have been conducted in India. Conclusions: In our study, there was a definite and significant decrease in FPA and internal tibial torsion with increasing age. The values of clinical anteversion also decreased with age along with a gradual decrease of internal rotation and an increase of external rotation (ER). The decrease of FA with age correlated better with increase of hip ER. FPA was a significant clinical parameter which gave us an objective picture of the change in both femoral and tibial torsions with age.
