Standard viewsĪP (Anterior-Posterior) pelvis and Lateral hip. It is characterized by an early pathologic contact during hip joint motion between skeletal prominences of. Particular care is needed in assessing the X-ray when physical examination is limited, for example if a patient is acutely confused. Femoroacetabular impingement (previously also called acetabular rim syndrome 1 or cervicoacetabular impingement 2 ) is a major cause of early osteoarthritis of the hip, especially in young and active patients 3 6. Repeat X-rays, CT or MRI may be required if pain persists.

In this case the X-ray may not show an obvious fracture. It is important to be aware that the common clinical signs of a shortened and externally rotated leg may be absent if the fracture is not displaced. Many hip fractures are clinically and radiologically obvious. The capsule surrounds the hip joint and a large part of the femoral neck (fig.

Remember to assess the surrounding pelvic bonesįractures of the proximal femur or 'hip' are a common clinical occurrence in elderly, osteoporotic patients. The hip joint is surrounded by a firm joint capsule.

Particular caution is required in the case of acutely confused patients.

Not all hip fractures are visible on the initial X-ray and follow-up imaging may be required if concern remains.

the unaffected leg is bent to stabilize the patient position i.e.

the patient is rolled at least 45° onto the side of interest with a hip flexion of 90°.

The lower borderline value does not change with age, nor is there any change in the average joint space with age. The normal value was slightly over 4 mm, scattered between 3 and 5 mm, except for elderly men in whom values of 6 mm or more may be normal. As this particular projection involves rolling the patient onto the side of interest, it is hence not suitable for trauma situations.įor trauma imaging of the hip, see: horizontal beam lateral. Hip Arthritis - Example of cartilage Figure 1 Hip Arthritis - Normal hip x-ray Figure 2. The hip joint space in standard anteroposterior images of 120 normal subjects was measured with the aid of a special transparent pattern. This chapter will include various osseous pathologies that can affect the hip joint such as stress fractures, osteonecrosis, or subchondral insufficiency fractures. suspected osteoarthritis of the hip) in an orthogonal plane to the AP projection. Imaging evaluation of the hip joint requires expert knowledge about the detailed anatomy and specific injuries.

Pain that is much more intense in the morning and subsides till the evening. Pain that worsens with strenuous activity. The hip joint space in standard anteroposterior images of 120 normal subjects was measured with the aid of a special transparent pattern. Some of these symptoms are as follows, Walking with a limp. This view assesses the hip joint for any potential fractures, dislocations, bone lesions or degenerative diseases (i.e. Even though there are five different types of arthritis they all have the same symptoms and may have similar characteristics on hip x-ray.
