What it is (overview)

An XR Hip 1 view is a diagnostic imaging test that uses a small amount of X-ray radiation to capture one image (one “view”) of the hip joint. The hip is a ball-and-socket joint made up of the top of the thigh bone (femur) and the hip socket (acetabulum) in the pelvis. A one-view hip X-ray provides a quick look at the alignment of the joint and the condition of the bones around it.

This medical test does not measure blood values or soft-tissue function. Instead, it shows the shape, position, and density of bone. It can help detect problems such as a fracture, dislocation, obvious bone deformity, or signs of degenerative disease (wear-and-tear changes like arthritis). Depending on the reason for the exam, the technologist may take an anteroposterior (AP) view or another single angle requested by the ordering clinician.

What results mean (in plain language): A “normal” result generally means the hip bones look intact, the joint is well aligned, and there are no clear signs of acute injury or major degenerative changes on that single view. An “abnormal” result might show a break in the bone (fracture), the ball of the femur sitting out of the socket (dislocation), joint space narrowing or bone spurs (common in osteoarthritis/degenerative joint disease), or other bony changes. Because this is only one view, your clinician may order additional X-ray views or other imaging (CT or MRI) if symptoms persist or if more detail is needed for an orthopedic evaluation.

When & why it's usually done

Clinicians commonly order an XR Hip 1 view when they need a fast, accessible way to evaluate hip pain and possible bone injury. It is often used in urgent care, emergency departments, and outpatient settings as part of an initial pain assessment and joint health evaluation.

This test is usually done if you have:

• Sudden hip pain after a fall, sports injury, or accident, especially when there is concern for a hip or pelvic fracture
• Difficulty walking, inability to bear weight, or severe pain with movement
• Hip deformity, leg appearing shortened or rotated, or suspected dislocation
• Persistent or worsening hip/groin pain that may be related to degenerative disease (such as osteoarthritis)
• Reduced range of motion, stiffness, or mechanical symptoms (catching, grinding) suggesting joint wear or structural change
• Follow-up imaging after known injury, hip surgery, or to check positioning of orthopedic hardware (as directed by your clinician)

Doctors may be more likely to order hip X-ray imaging if you have risk factors for fractures or joint problems, such as osteoporosis, older age, use of medications that weaken bone (for example, long-term steroids), high-impact trauma, or previous hip injury. If a single-view X-ray does not fully answer the clinical question, additional views or advanced imaging may be recommended.

Common diseases related to it

• Hip fracture (including femoral neck and intertrochanteric fractures)
• Hip dislocation
• Osteoarthritis of the hip (degenerative joint disease)
• Femoroacetabular impingement (FAI) and related bony shape abnormalities
• Hip dysplasia (shallow hip socket) and associated joint wear
• Avascular necrosis (osteonecrosis) of the femoral head (X-ray may show later-stage changes)
• Inflammatory arthritis affecting the hip (e.g., rheumatoid arthritis) with chronic joint damage
• Bone tumors or cystic bone lesions (occasionally first seen on X-ray)
• Pelvic or proximal femur stress injury/stress fracture (may be subtle early on)

Health goals where it may help

• Identify the cause of hip or groin pain to guide safe treatment and activity levels
• Rule out or confirm suspected fracture or dislocation after injury for timely care
• Support orthopedic evaluation and treatment planning (including referral decisions)
• Monitor progression of degenerative hip disease (arthritis) and assess joint space changes
• Evaluate joint alignment and overall joint health to help plan physical therapy or rehabilitation
• Assess post-procedure or post-injury healing when follow-up imaging is needed
