A prominent resonance frequency, due to swollen soft tissue, was observed below the first mode resonance frequency of the bone in the mechanical impedance measurement of the limb. Distinction should be made between these two frequencies in the diagnosis of fracture healing. A two-port network analogy is used to explain the existence of the resonance frequency.
