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. [ 1] Hip dysplasia may occur at birth or develop in early life. [ 1] Regardless, it does not typically produce symptoms in babies less than a year old. [ 3]
X-rays of hip dysplasia are one of the two main methods of medical imaging to diagnose hip dysplasia, the other one being medical ultrasonography. [1] [2] Ultrasound imaging yields better results defining the anatomy until the cartilage is ossified. When the infant is around 3 months old a clear roentgenographic image can be achieved.
Barlow maneuver. The Barlow maneuver is a physical examination performed on infants to screen for developmental dysplasia of the hip. It is named for Dr. Thomas Geoffrey Barlow (September 25, 1915 – May 25, 1975), an English orthopedic surgeon, who devised this test. It was clinically tested during 1957–1962 at Hope Hospital, Salford ...
Ortolani test. Hip-joint, front view. The Ortolani test is part of the physical examination for developmental dysplasia of the hip, along with the Barlow maneuver. [ 1] Specifically, the Ortolani test is positive when a posterior dislocation of the hip is reducible with this maneuver. [citation needed] This is part of the standard infant exam ...
The Galeazzi test, also known as the Allis sign, is used to assess for hip dislocation, primarily in order to test for developmental dysplasia of the hip. It is performed by flexing an infant's knees when they are lying down so that the feet touch the surface and the ankles touch the buttocks. If the knees are not level then the test is ...
Cleidocranial dysostosis ( CCD ), also called cleidocranial dysplasia, is a birth defect that mostly affects the bones and teeth. [1] The collarbones are typically either poorly developed or absent, which allows the shoulders to be brought close together. [1] The front of the skull often does not close until later, and those affected are often ...
Hip dysplasia is a congenital condition in which the hip is deformed in a way that decreases the congruency between the head of the femur and the acetabulum of the pelvis. [22] Bony congruence is a stabilizing factor to the hip joint, so the decrease in this conferred by hip dysplasia makes one more susceptible to dislocation.
Frequency. 1 in 20,000 newborns [ 1] Poland syndrome is a birth defect characterized by an underdeveloped chest muscle and short webbed fingers on one side of the body. [ 3][ 1] There may also be short ribs, less fat, and breast and nipple abnormalities on the same side of the body. [ 1] Typically, the right side is involved. [ 3]
