Hip dysplasia [SEP] Introduction
Hip dysplasia is an abnormality of the hip joint where the socket portion does not fully cover the ball portion, resulting in an increased risk for joint dislocation. Hip dysplasia may occur at birth or develop in early life. Regardless, it does not typically produce symptoms in babies less than a year old. Occasionally one leg may be shorter than the other. The left hip is more often affected than the right. Complications without treatment can include arthritis, limping, and low back pain. Risk factors for hip dysplasia include family history, certain swaddling practices, and breech birth. If one identical twin is affected, there is a 40% risk the other will also be affected.
