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 can be diagnosed by ultrasound [44] and projectional radiography ("X-ray"). [45] Ultrasound imaging is generally preferred at up to 4 months due to limited ossification of the femoral head up until then, and is the most accurate method for imaging of the hip during the first few months after birth.
X ray of deformity by Legg–Calvé–Perthes disease of the right hip (left side of X-ray) Children younger than six have the best prognosis, since they have time for the dead bone to revascularize and remodel, with a good chance that the femoral head will recover and remain spherical after resolution of the disease.

Hip dislocations can also occur following a hip replacement or from a developmental abnormality known as hip dysplasia. [6] Hip dislocations are classified by fracture association and by the positioning of the dislocated femoral head. [7] [8] A posteriorly positioned head is the most common dislocation type. [5] Hip dislocations are a medical ...
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).
Breed: Some dog breeds are more likely to develop chronic health issues such as diabetes (Australian terriers and Samoyeds) and hip dysplasia (Labrador Retrievers and German Shepherds).
Projectional radiography ("X-ray") is the first imaging technique of choice in hip pain, not only in older people with suspected osteoarthritis but also in young people without any such suspicion. In this case plain radiography allows categorization as normal hip or dysplastic hip , or with impingement signs, pincer, cam, or a combination of both.
