Background: The valgus cut angle (VCA) of the distal femur in Total Knee Arthroplasty (TKA) is measured preoperativelyon three-joint alignment radiographs. The anatomical axis of the femur can be described as the anatomical axis of thefull length of the femur or as the anatomical axis of the distal half of the femur, which may result in different anglesin some cases. During TKA, the anatomical ...

    Background: Evaluating the landmarks for rotation of the distal femur is a challenge for orthopedic surgeons. Although the posterior femoral condyle axis is a good landmark for surgeons, the surgical transepicondylar axis may be a better option with the help of preoperative CT scanning. The purpose of this study was to ascertain relationships among the axes’ guiding distal femur rotational ...

AIM To review and study the effect of lengthening along the anatomical axis of long bones and its relation to the mechanical axis deviation. METHODS We try in this review to calculate and discuss the exact clinical impact of lengthening along the anatomical axis of the femur on affecting the limb alignment. Also we used a trigonometric formula to predict the change of the femoral distal anato...

Background: The traditional assumption has been that there is a close relationship between the electrical and anatomical axes of the heart. The aim of this study was to test the hypothesis that there is a correlation between the electrical and anatomical axes of the heart, in both the frontal and transverse planes, in healthy subjects. Methods: Ninety-four healthy volunteers (48 males, 46 femal...

The treatment of knee osteoarthritis and the preparation for total knee arthroplasty require repetitive imaging to guide preoperative planning and operative technique. Full-length standing anteroposterior images are the gold standard in assessing the alignment of the limb via the measurement of the mechanical axis of the knee. The anatomical axis can be obtained from a more limited image of the...

background: the celiac axis, superior mesenteric artery (sma), and hepatic artery are the most important branches of abdominal aorta due to their vascularization field. the aim of our study was to evaluate the prevalence of different anatomical variation of celiac axis, sma, hepatic artery, and its branches with multidetector computed tomography (mdct) angiography of upper abdomen arteries. mat...

BACKGROUND The anatomical axis of the femur is crucial for determining the correct alignment in corrective osteotomies of the knee, total knee arthroplasty (TKA), and retrograde and antegrade femoral intramedullary nailing (IMN). The aim of this study was to propose the concept of different anatomical axes for the proximal and distal parts of the femur; compare these axes in normally aligned su...

BACKGROUND Precise preoperative measurement of knee alignment is needed to calculate the accurate angle of correction at proximal tibia osteotomy for medial gonarthrosis. METHODS We performed a prospective study to compare the reproducibility of measuring the mechanical and anatomical axes. Thirty-two patients (32 knees) with medial compartment osteoarthritis to be treated with proximal tibia...
