چکیده
OBJECTIVE To ascertain the geometry of the femur in the Brazilian population by means of a radiographic study and to correlate the values with regard to sex and right/left side. METHODS Five hundred anteroposterior radiographs of the pelvis of skeletally mature patients (250 of each sex) who did not present any osteoarthrosis, fractures or tumoral or infectious lesions were analyzed. The length and width of the femoral neck, length of the femoral axis, neck-shaft angle and femoral offset were measured. RESULTS The following means were observed: 36.54 mm for the length of the femoral neck; 37.48 mm for the width of the femoral neck; 108.42 mm for the length of the femoral axis; 130.47° for the neck-shaft angle; and 44.4 mm for the femoral offset. CONCLUSION The mean values for the main measurements on the proximal femur in Brazilians differed from those of previous studies. It could also be shown that there was a statistically significant mean difference between men and women for all the variables, both on the left and on the right side, and that the men had greater means than the women.

Background & Aim: Normal axial alignment restoration in lower extremities is very important for surgeons that perform reconstructive surgeries. Since normal values of axial alignment in Iranian population aren't available, normal values in western countries are used in practice. In this study axial alignment norms in Iranian adults were determined and the results were compared with those of...
متن کاملEffects of Hip Geometry on Fracture Patterns of Proximal Femur
Background: Some studies have previously shown that geometry of proximal femur can affect the probability of fracture and type of fracture. It happens since the geometry of the proximal femur determines how a force is applied to its different parts. In this study, we have compared proximal femur’s geometric characteristics in femoral neck (FNF), intertrochanteric (ITF) and Subtrochanteric (ST...

Background: The aim of this study is to evaluate the geometry of the distal femur and the proximal tibia in the osteoarthritic knee using 3D reconstructive CT scan imaging. Methods: 449 patients with knee osteoarthritis were treated surgically in our center with patient-specific technology total knee arthroplasty. Preoperatively, all the patients underwent a CT scan according to a standard ...
متن کاملRadiographic anatomy of the proximal femur: correlation with the occurrence of fractures
OBJECTIVE To evaluate the correlation between radiographic parameters of the proximal femur anatomy and fractures. METHODS Three hundred and five digital x-rays of the pelvis were analyzed in the anteroposterior view. Of these x-rays, twenty-seven showed femoral neck or transtrochanteric fractures. The anatomical parameters analyzed were: femoral neck width (FNW), femoral neck length (FNL), f...
متن کاملA Survey on Morphometry and Topography of Nutrient Foramina and Measurement of Other Anthropometric Parameters in Human Femora and Tibiae: A Descriptive Study
Background and Objectives: Measuring the dimensions of bones is essential from the perspective of surgery related to bones and joints. The position of the nutrient foramen and the bones' dimensions vary in different populations. The aim of this study was to determine some anthropometric dimensions and topography of nutrient foramina in the femora and tibiae. Materials and Methods: In this desc...
