Nov 3, 2025 · Computed tomography scanogram for leg length discrepancy assessment is performed in patients (children in most cases) with suspected inequality in leg length …

Digital imaging usually employs a hybrid of these traditional techniques by obtaining the three exposures centered at the hip, knee, and ankle joints with the patient standing upright.

Patients with less than 20 mm of mechanical axis deviation on the standing radiograph had better correlation with the scanogram than those with larger magnitude of malalignment.

Mar 20, 2025 · For leg length discrepancy assessment, a standing anteroposterior (AP) radiograph of both lower extremities, known as a scanogram or orthoroentgenogram, is the …

While several studies noted that the scanogram provided reliable measurements with minimal magnification, a full-length standing AP computed radiograph (teleoroentgenogram) is a more …

Dec 10, 2025 · The scanogram allows physicians to measure the exact length of the femur (thigh bone) and the tibia (shin bone) in both legs to determine the precise location and extent of the …

Example of a well-positioned full length standing AP view x-ray: This x-ray study includes both legs from the pelvis to the ankle on one film. Both lower extremities are oriented with each …

Mar 5, 2024 · We prospectively compared measurements of the weight-bearing line ratio (WBL), hip-knee-ankle (HKA) angle, and joint convergence angle (JLCA) in 46 sets of supine weight …

Dec 28, 2024 · Long-leg standing radiograph (LLR) at 6 weeks post-op is the gold standard for assessing alignment, but its reliance on weight-bearing and positioning makes it less practical …

Limb-length discrepancy is frequently assessed in lower limbs using an orthoroentgenogram. Techniques include a single film view termed teleoroentgenogram, or two views each of which …
