What it is (overview)

An XR Pelvis 1 view (pelvis X-ray, single-view pelvic radiograph) is a quick, noninvasive diagnostic imaging test that uses a small amount of ionizing radiation to create a black-and-white picture of the bones and joints in your pelvic region. In one view (one angle), it typically shows the pelvic ring (hip bones, pubic bones, and sacrum) and can include part of one or both hip joints depending on the reason for the exam and how the image is taken.

This test is designed mainly to evaluate bone health and the alignment of the pelvis and hips. It helps a radiology provider look for:

• Fractures (breaks) or cracks in the pelvic bones or upper femur
• Dislocations or abnormal positioning of the hip joint
• Visible bone abnormalities such as areas that look worn down, misshapen, or unusually dense/less dense

What the results mean: The X-ray is interpreted by a radiologist, who reports whether the pelvic bones and hip joints look normal, whether there is evidence of a pelvic fracture or hip dislocation, and whether there are signs of chronic changes such as degenerative conditions (for example, arthritis). Because it is only one view, some injuries or subtle findings may be harder to see; if symptoms are significant or the findings are unclear, your clinician may order additional X-ray views or more detailed imaging like a CT scan or MRI.

When & why it's usually done

A doctor may order an XR Pelvis 1 view when they need a fast, first-look assessment of the pelvis and hips—especially in urgent settings. Common reasons include:

After trauma or an accident: Falls, motor vehicle crashes, sports injuries, or any event causing hip/pelvic pain, trouble walking, or an inability to bear weight. A single-view pelvis X-ray is often used to quickly check for a fracture, dislocation, or pelvic ring injury.

Hip or groin pain: Ongoing pain in the hip, groin, buttock, or lower pelvis may prompt imaging to look for arthritis-related changes, old injuries, or other structural issues.

Limited movement or abnormal gait: Stiffness, reduced range of motion, or limping can be related to hip joint wear-and-tear or prior injury; X-ray can help assess joint alignment and bony changes.

Suspected degenerative changes: For people with risk factors such as older age, a history of joint injury, or long-term joint stress, a pelvis X-ray may help evaluate osteoarthritis and other degenerative conditions affecting the hip joint.

Follow-up or treatment planning: It may be used to monitor healing after a known fracture, check the position of hardware after orthopedic surgery, or help guide next steps such as physical therapy, pain management, or referral to orthopedics.

Important note about sensitivity: If there is strong concern for a hip fracture (especially in older adults) but the X-ray does not clearly show one, clinicians may recommend additional imaging (often MRI or CT) because some fractures can be difficult to see on a single-view X-ray.

Common diseases related to it

• Pelvic fracture (including pubic ramus fractures and pelvic ring injuries)
• Hip fracture (proximal femur fracture)
• Hip dislocation or subluxation
• Osteoarthritis (degenerative joint disease) of the hip
• Osteoporosis-related insufficiency fractures
• Sacroiliac (SI) joint degeneration or inflammation (may be partially assessed)
• Leg length discrepancy or pelvic alignment abnormalities (screening/initial assessment)
• Avascular necrosis of the femoral head (may show later bony changes)
• Bone tumors or bone lesions (incidental findings that may require further imaging)

Health goals where it may help

• Ruling out a fracture after a fall or other trauma to support fast, safe treatment decisions
• Assessing hip joint degeneration to guide pain relief, activity modification, and physical therapy plans
• Monitoring bone health concerns (e.g., suspected osteoporosis-related fractures) and supporting prevention strategies
• Planning orthopedic care (such as surgery evaluation, hardware checks, or follow-up imaging)
• Improving mobility and function by identifying structural causes of hip/groin pain or limited range of motion
