Computed tomography scanogram for leg length discrepancy assessment

Radiopaedia • CC-by-nc-sa 3.0 • de

Computed tomography scanogram for leg length discrepancy assessment is performed in patients (children in most of the cases) with suspected inequality in leg length (anisomelia).

Technique
  • obtained images are typically anteroposterior (AP) scout views of the bilateral femurs and tibias
  • femoral length is estimated by measuring the distance between superior aspect of the femoral head and the distal portion of the medial condyle
  • tibial length is determined by measuring the distance between the medial tibial plateau and the tibial plafond
