Abstract EN
The bone mineral density (BMD) of retrieved cancellous bone samples is compared to the BMD measured in vivo in the respective osteoarthritic patients.
Furthermore, mechanical properties, in terms of structural modulus (Es) and ultimate compression strength (σmax) of the bone samples, are correlated to BMD data.
Human femoral heads were retrieved from 13 osteoarthritic patients undergoing total hip replacement.
Subsequently, the BMD of each bone sample was analysed using dual energy X-ray absorptiometry (DXA) as well as ashing.
Furthermore, BMDs of the proximal femur were analysed preoperatively in the respective patients by DXA.
BMDs of the femoral neck and head showed a wide variation, from 1016±166 mg/cm2 to 1376±404 mg/cm2.
BMDs of the bone samples measured by DXA and ashing yielded values of 315±199 mg/cm2 and 347±113 mg/cm3, respectively.
Es and σmax amounted to 232±151 N/mm2 and 6.4±3.7 N/mm2.
Significant correlation was found between the DXA and ashing data on the bone samples and the DXA data from the patients at the femoral head (r=0.85 and 0.79, resp.).
Es correlated significantly with BMD in the patients and bone samples as well as the ashing data (r=0.79, r=0.82, and r=0.8, resp.).
