tibia area measurement tibia-fibula cross-sectional area 2013-07-29T11:06:00Z CMO:0001718 JSmith Measurement of all or part of the cross-sectional area of the tibia-fibula, the portion of the two bones of the lower leg of bipeds or hindlimb of quadrupeds (tibia, the medial and larger bone, and fibula, the lateral and smaller bone) which are fused to form a single bone, e.g. the distal third of the rodent tibia and fibula. The tibia-fibula cross-sectional area is a measurement of the extent of a plane through, that is, perpendicular to the longest axis of the bone. clinical_measurement_ontology tibia/fibula cross-sectional area tibio-fibular complex cross-sectional area tibiofibular fusion cross-sectional area fibula area
