A scanogram of the lower limb is a radiographic technique that obtains calibrated images of the hip, knee and ankle to measure femoral and tibial lengths and detect leg‑length discrepancy. It can be done with conventional X‑ray (three sequential exposures) or CT‑based methods for higher precision. Results guide orthopaedic assessment and surgical planning such as lengthening or shortening procedures.

A scanogram X-ray is used to obtain precise, full-length images of limbs to measure bone and leg-length discrepancies and alignment. It's commonly used for preoperative planning in orthopedics—leg-length correction, deformity assessment, joint-replacement templating—and for postoperative follow-up. The technique images hip, knee and ankle in a single series to provide accurate measurements for diagnosis and treatment planning.

Costs for a scanogram vary by country and provider. In India it often ranges roughly ₹500–₹3,000 at private centers; in the United States typical out‑of‑pocket fees run about $100–$600; in the UK it’s usually provided free on the NHS or about £50–£200 privately. Final price depends on facility, additional views or reports, and insurance—check the imaging center for exact charges.

A lower limb X-ray is commonly called a lower limb radiograph or a plain radiograph of the lower limb. It may be done as separate views (hip, femur, knee, tibia/fibula, ankle) or as a long-leg (full-length) radiograph to assess bone alignment and leg length. It’s used to evaluate fractures, joint problems, infections and degenerative changes.

The Lower Limb Score (often the Lower Extremity Functional Scale) is a 20-item patient questionnaire assessing difficulty with everyday lower‑limb tasks. Each item is scored 0–4 for a total of 0–80, with higher scores indicating better function. It quantifies mobility and pain impact, and is used to monitor rehabilitation progress and guide clinical treatment decisions.

For a standard scanogram you typically do not need to fast — you can eat and take usual medications. Fasting may be required if contrast, sedation or anaesthesia is planned (commonly 4–6 hours for solids, 2 hours for clear fluids). Follow the imaging centre’s specific instructions, tell them if you are pregnant or diabetic, and remove metallic items before the scan.
