The aims to study the femoral offset and its relationship to femoral neck-shaft angle and torsion angle. One hundred paired (50 males and 50 females) Chinese femurs were used to measure the femoral offset, femoral neck-shaft angle and torsion angle. The data were analyzed by SPSS software. Femoral offsets were male right 44.40±4.56 mm, left 42.70±4.95 mm; female right 39.90±6.00 mm, left 38.90±...

BACKGROUND We conducted this radiographic study in the elderly population with proximal humeral fracture aiming to evaluate 1) the serial changes of neck-shaft angle after locking plate fixation and 2) find relationship between change in neck shaft angle and various factors such as age, fracture pattern, severity of osteoporosis, medial support and initial reduction angle. METHODS Twenty-five...

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...

Background and Objective: Arthrosis of the hip joint is one of the most common complications of patients and many efforts have been made to find its etiology. One of the subjects important for researchers is morphologic parameters of the hip joint and its relationship with osteoarthritis of this joint. Since these parameters themselves are affected by physical parameters of the body and the rac...

In this study, an analytical model is developed to study crack breathing behavior under the effect of crack location and unbalance force. Crack breathing behavior is determined using effectual bending angle by studying the transient change in closed area of the crack. The status of the crack of a balanced shaft is symmetrical about shaft rotational angle and the duration of each crack status re...

This paper describes the treatment of the more vertical type of subcapital fracture of the neck of tile femur by reduction, nailing, and immediate wedge osteotomv, with fixation by a plate attached to the head of the nail. Ten cases are recorded. As in other clinics, it had been found that the results of treatment, by the standard Smith-Petersen technique, of subcapital fractures of the neck of...

BACKGROUND The aim of this study was to answer the following two questions: 1) Do the radiological parameters of dysplasia have significant correlations between themselves or with the parameters of the proximal femoral deformity and vice versa? 2) Do the physical parameters have a significant correlation with the radiological parameters of hip dysplasia and proximal femoral deformity? METHODS...

In the present study, we aimed to verify the discrepancies in the measured femoral neck anteversion (FNA) values relative to the retrocondylar plane and computed tomography plane by using computer simulation. We observed that the measured FNA values increased with an increase of each degree of extension and adduction. Moreover, in cases where the neck shaft angle was larger, the measured FNA va...

Commonly, total hip prostheses have had a higher neck-shaft angle than the host bone and thus a tendency to reduce the femoral offset. Restoration of the femoral offset may be important as it has been shown to enhance hip stability and to improve the range and strength of abduction. The purpose of this study was to determine which of two designs was best able to restore femoral offset in compar...

OBJECTIVE To compare the existence of agreement between measurements of anteversion of the femoral neck and the degrees of osteoarthritis and abnormality of the neck-shaft angle in patients with unilateral idiopathic hip osteoarthritis, among three evaluators. METHODS Forty-two patients with unilateral hip osteoarthritis were evaluated by means of simple radiography and computed tomography. ...
