Validation of the femoral anteversion measurement method used in imageless navigation
Total hip arthroplasty restores lost mobility to patients suffering from osteoarthritis and acute trauma. In recent years, navigated surgery has been used to control prosthetic component placement. Furthermore, there has been increasing research on what constitutes correct placement. This has resulted in the definition of a safe-zone for acetabular cup orientation. However, there is less defini...
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...
متن کاملImageless computer navigation for placement of the femoral component in resurfacing arthroplasty of the hip.
We have investigated the accuracy of placement of the femoral component using imageless navigation in 100 consecutive Birmingham Hip Resurfacings. Pre-operative templating determined the native neck-shaft angle and planned stem-shaft angle of the implant. The latter were verified post-operatively using digital anteroposterior unilateral radiographs of the hip. The mean neck-shaft angle determin...
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 کاملFemoral neck anteversion: values, development, measurement, common problems.
The femoral neck anteversion angle is an important factor for hip stability and normal walking. It is multifactoral result of evolution, heredity, fetal development, intrauterine position, and mechanical forces. Abnormal FNA sometimes can be associated with many clinical problems ranging from harmless intoeing gait in the early childhood, to disabling osteoarthritis of the hip and the knee in t...
