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]
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).
Protrusio acetabuli is an uncommon defect of the acetabulum, the socket that receives the femoral head to make the hip joint. The hip bone of the pelvic bone/girdle is composed of three bones, the ilium, the ischium and the pubis. In protrusio deformity, there is medial displacement of the femoral head in that the medial aspect of the femoral ...
Femoroacetabular impingement (FAI) is a condition involving one or more anatomical abnormalities of the hip joint, which is a ball and socket joint. [1] It is a common cause of hip pain and discomfort in young and middle-aged adults. [2]
Organisms in the dinosauria clade are defined by a perforate acetabulum, which can be thought of as a "hip-socket". The perforate acetabulum is a cup-shaped opening on each side of the pelvic girdle formed where the ischium , ilium , and pubis all meet, and into which the head of the femur inserts.
The criteria can be used on multiple joints — the hip being the most tested given its frequency of diagnosis and importance to the patient's mobility. The knee and the ankle can also experience these symptoms and the criteria can be applied to symptomatic joints such as these.
The diagnosis can be made in the typical setting of pain or limp in a young child who is not generally unwell and has no recent trauma. There is a limited range of motion of the hip joint. Nevertheless, children with transient synovitis of the hip can usually weight bear. This is an important clinical differentiating sign from septic arthritis. [8]
In children over about 3 to 4 years of age, this line should be smooth and undisrupted, otherwise it may indicate a fracture or hip dysplasia. [6] However, in infants this line can be unreliable as it depends on the rotation of the hip when the image is taken. [7] (D) The acetabular index measures the acetabular roof slope. It is the most ...
