Computed tomography scanogram for leg length discrepancy assessment
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).
- 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
