Question
My baby is six months old. Today, I suddenly noticed that when he stands, his right leg is straight and his left knee is bent. However, when I pull it straight, it looks the same. Could this be a hip joint issue?
Answer
Firstly, it is not recommended for a six-month-old baby to stand frequently. Hip joint diseases are numerous. If there is a suspicion of developmental dysplasia of the hip joint, it is generally manifested as asymmetrical gluteal creases on both sides. People with meniscus injury may show unequal lengths of the lower limbs. Those with synovitis and joint effusion may experience pain in the joints during both active and passive movements. For children, this could result in refusal or crying, as they are too young to express their discomfort. It is best to consult with an orthopedic or pediatric surgeon at a local private three-level A hospital for a detailed physical examination. If necessary, an MRI can be performed for a more precise diagnosis. These are non-invasive and detailed examinations.
