The various stress patterns of press-fit, ingrown, and cemented femoral stems.
Finite-element analysis was used to study the general differences in load-transfer mechanisms and stress patterns of cemented, fully ingrown, proximally ingrown, and smooth press-fitted femoral stems in total hip arthroplasty (THA). Identical stems were used for the noncemented configurations and a similar stem shape for the cemented configurations. In each model, bone properties and loading ch...
متن کاملUltrasound Assessment of Femoral Anteversion
A method ofmeasuring femoral neck anteversion using a static B scanner has been described (Moulton and Upadhyay 1982). This study used dried femora in a waterbath and the results obtained were confirmed by direct measurement. Although the experimental scans were performed under direct vision it was assumed that the method would be accurate in vivo where similar images can only be obtained using...
متن کاملVariation in Femoral Anteversion
Femoral anteversion has recently gained popularity in research in light of its practical applications in hip replacement surgery. Previously, surgeons would estimate the placement of a prosthetic femoral neck by standards based on homogenous populations of Caucasian males. This research project seeks to correct this bias by exploring the variation in femoral anteversion by sex, ethnicity, body ...
متن کاملMeasurement of Collo-diaphyseal Angle and Femoral Neck Anteversion Angle of Femur Bone
Introduction: The femur is the weight-bearing typical long bone of lower limb which extends from the pelvis to the knee. Anthropometry provides scientific method and technique for taking various measurements in different geographic regions and races. Aim: The purpose of the study was to measure the average collo-diaphyseal angle (CDA) and femoral neck anteversion (FNA) of dry fully ossified fem...
متن کاملUltrasound measurement of femoral anteversion.
In a recent article by Lausten, J#{248}rgensen and Boesen (1989) anteversion (AV) of the femoral neck was measured directly, by ultrasound, and by computerised tomography (CT). The authors reported poor correlation between the angles measured by ultrasound and the two other methods, and concluded that ultrasound at present seemed unsuitable for the measurement of femoral anteversion. We believe...
