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 leng...
OBJECTIVE This retrospective study was carried out to determine the typical patterns of (18)F-FDG uptake in uncomplicated total hip arthroplasty (THA). SUBJECTS AND METHODS (18)F-FDG-PET images of 62 asymptomatic THA patients who had undergone whole body scanning were evaluated for this retrospective study. The uptake was assessed qualitatively as positive or negative in the head/neck and the...
Femoral neck fractures are common in the elderly and are broadly grouped into either intracapsular or extracapsular fractures. We report an unusual femoral neck fracture that had features of both and discuss the management of such a case.
Osteoporosis is a major public health problem. Menopause provokes a decrease in bone mineral density (BMD) that causes postmenopausal osteoporosis. This study aimed to compare different regions for BMD measurement in postmenopausal women, with regarding to the effect of age, weight and height. 313 osteoporotic menopaused women were classified in 1 of 3 categories on the basis of their age (50-...
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...
Children who present late with hip dislocation may require femoral osteotomy after reduction, to correct valgus and anteversion deformity of the femoral neck. After these procedures proximal femoral growth is unpredictable. We have studied proximal femoral growth in 40 children who had been treated by femoral osteotomy. Preoperatively, the mean femoral neck-shaft angle was 5 degrees greater on ...
Background: Non-union of the femoral neck fracture in young and middle-aged patients is a problem and can be very debilitating. If the femoral head is viable, the most appropriate treatment is valgus osteotomy that without refreshing of the fracture site, it only increases the femoral neck angle to change shearing force to compression force. In this study, after refreshing the non-union site an...
background: the purpose of this study was to evaluate long-term changes in bone density profile among survivors of childhood acute lymphoblastic leukemia. patients and methods: this was a 5 year prospective study comprised of thirty-one survivors of childhood acute lymphoblastic leukemia with a mean age of 11.8 (4.6) years, who completed therapy at least 1 year previously (according to the all-...
Introduction: Fat body mass and body mass index (BMI) are important determinants of bone mineral density (BMD). Although the mechanism involved in this relation is uncertain, it seems that aromatization of androgens to esteradiol in adipose tissue is the most important explanatory mechanism. Materials & Methods: The purpose of this study is to evaluate the correlation between BMI and BMD amon...
