Introduction
It is both normal and abnormal for newborns to have bent legs at birth. Due to limited space in the uterus, fetuses remain in a position with bent legs throughout their development, resulting in bent legs at birth—this condition is considered normal. However, if the leg curvature does not improve, it may be caused by delayed growth and development, high muscle tone, brain injury, or cerebral palsy.
It is usually normal for newborns to have bent legs at birth, although it can sometimes indicate an abnormal condition. Whether the leg curvature is normal or not depends on the specific underlying cause.
1. Normal condition
During the embryonic stage, due to limited space in the uterus, fetuses remain with bent legs throughout development, which results in the appearance of bent legs at birth. This condition is considered normal. As the child grows and their bones and tendons develop properly, the leg curvature typically improves significantly, so there is generally no need for concern.
2. Abnormal condition
If the leg curvature persists after birth and does not show clear improvement, it may be caused by factors such as delayed growth and development, high muscle tone, brain injury, or cerebral palsy. It is recommended to seek medical attention promptly. Treatment should target the specific underlying cause, and active rehabilitation training should be implemented to prevent negative impacts on leg appearance and future mobility.
