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.
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]
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.
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 performed preferably in early infancy.
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, Lancashire. [1]
There are typically four classes (or types) of PFFD, ranging from class A to class D, as detailed by Aitken. [4] [5]Type A — The femur bone is slightly shorter on the proximal end (near the hip), and the femoral head (the ball of the thigh bone that goes into the hip socket) may not be solid enough to be seen on X-rays at birth, but later hardens (ossifies).
One leg stance accounts for about 60% of the gait cycle, and during the stance phase, there is approximately three times the body weight transmitted to the hip joint. [citation needed] The hip abductors' action accounts for two thirds of that body weight. A Trendelenburg sign can occur when there is presence of a muscular dysfunction (weakness ...
