Physical exam should also involve assessing passive internal rotation of the hip during flexion, as range of motion is reduced in proportion to the size of a cam lesion. [10] Flexing the hip to 90 degrees, adducting, and internally rotating the hip, known as the FADDIR test, should also be performed. [10] It is positive when it causes pain.
The first form is caused by a cam-deformity where extra bone is present on the femoral head, which leads to the head being non-spherical. The second deformity is referred to as a pincer deformity and it is due to an excess growth of the acetabular socket. [4] The third type of FAI is a combination of the first two deformities.
Total hip replacement is most commonly used to treat joint failure caused by osteoarthritis.Other indications include rheumatoid arthritis, avascular necrosis, traumatic arthritis, protrusio acetabuli, [5] certain hip fractures, benign and malignant bone tumors, [6] arthritis associated with Paget's disease, [7] ankylosing spondylitis [8] and juvenile rheumatoid arthritis. [9]
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 ...
Coxa vara is a deformity of the hip, whereby the angle between the head and the shaft of the femur is reduced to less than 120 degrees. This results in the leg being shortened and the development of a limp. It may be congenital and is commonly caused by injury, such as a fracture.

Hip arthroscopy was initially used for the diagnosis of unexplained hip pain, but is now widely used in the treatment of conditions both in and outside the hip joint ...
The Chargers went 11-6 this season, Harbaugh's first back in the league after he led Michigan to a national championship the year before, and reached the playoffs for the second time in the past ...
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]
