Question
A three-month-old baby has a difference in leg thickness between the left and right legs, but the lengths are the same and the motor function is normal. What could be the possible reasons for this condition?
Answer
Based on the provided medical history, if the leg lengths are the same, the possible cause might be asymmetrical muscle growth and development. This may not be a significant issue and can be observed for a period of time first. Uneven leg thickness is commonly seen in cases of poor lower limb blood circulation, hip dysplasia, or meniscus injury. It is recommended to consult with a pediatric orthopedic department promptly for a follow-up examination and to undergo hip joint and lower limb vascular color Doppler ultrasound for further diagnosis. These are suggestions for the question ‘Why might a three-month-old baby have uneven leg thickness between the left and right legs,’ hoping it will be helpful to you, and wishing you good health.
