[Reduced loading of one lower limb as a cause of local osteopenia].
An impact of diminished mechanical loading of lower extremity on bone densitometry has been quantitatively assessed with ultrasound. Seventy-three females with lower limb fracture history, coxarthrosis or scoliosis were evaluated. Both heels were submitted to measurements with Achilles densitometer (Lunar, USA). The following parameters were analyzed: Speed of Sound, Broadband Ultrasound Attenuation and Stiffness Index. Decreased values of all parameters were found in unloaded extremities. Speed of Sound was reduced most and in the group with fracture history. To avoid local bone loss short immobilization, early rehabilitation and pharmacotherapy is suggested.
