General Notes
This is a frontal X-ray of the pelvis and hips.
Spine, sacrum, both hip joints, and proximal femurs are visible.
Left Hip
The left femoral head appears irregular and flattened.
Joint space is severely reduced, almost bone-on-bone, suggesting advanced osteoarthritis or avascular necrosis (AVN).
There is increased sclerosis (whitening) in the acetabulum and femoral head—again, consistent with chronic degeneration.
Possibly some osteophyte (bone spur) formation at the joint margins.
Right Hip
The right hip joint has better preservation of joint space, but there’s still evidence of early joint narrowing and some sclerosis.
Suggests milder arthritic changes compared to the left.
Pelvis and Sacroiliac Joints
Sacroiliac joints look reasonably maintained, with no obvious fusion or erosion.
Symmetry of the pelvis is intact.
Other Observations
Bowel gas is visible—normal in this type of image.
No visible fractures.
Spine shows mild degenerative changes in the lower lumbar vertebrae—common with age.
Likely Diagnosis
Advanced osteoarthritis of the left hip, possibly needing joint replacement.
Early degenerative changes on the right side.
No signs of fracture or acute bony injury.
Suggestions
An orthopaedic consultation is advisable—especially to confirm whether the left hip needs replacement.
If you’re having pain in both legs, this X-ray supports severe left hip pathology, but additional issues (like spinal nerve impingement or vascular disease) could also be contributing.
Consider lumbar spine imaging and vascular assessment (e.g. Doppler).
Second X-ray
This image was taken at the same time as the first, but from a slightly different angle. While it offers a new perspective, it largely confirms the findings of the first X-ray without introducing new concerns.
- Left Hip: The image clearly confirms advanced joint space narrowing, flattening of the femoral head, and sclerosis—features consistent with either severe osteoarthritis or avascular necrosis.
- Right Hip: Mild degenerative changes remain visible, including early joint space narrowing and surface irregularity. No progression beyond what was seen in the first image.
- Pelvic Symmetry: Despite slight rotation of the image, the sacroiliac joints appear symmetric and stable. There is no indication of acute injury or disruption.
- Soft Tissue and Bowel Gas Patterns: These are slightly more defined in this image. No abnormal calcifications, foreign bodies, or signs of obstruction are seen.
What this image adds: The alternative angle gives a better view of the acetabulum and helps confirm the severity of degeneration in the left hip. It also reinforces the interpretation that the right hip shows only early changes. While not revealing any new findings, this image supports the diagnosis and may assist with orthopaedic planning.
