In this study, we investigated variations of the angle between neck and shaft of femur after amputation of tigh above the knee. In amputated tigh the angle between neck and shaft of the femur is decreased than normal (nearly 90° degrees) (coax vara). The angle of the normal femur usually increases due to weight bearing (coax valga). In the patients that both tighs have been amputated the change...
Background: In a total knee arthroplasty surgery the goal is to produce 90 degree angle between the knee articular lobe and the mechanical femoral line. Most orthopedic surgeons usually utilize a 5 to 7 degree for distal femoral cutting angle. In this study we will aim at clearing this question, that whether the” five-seven degree” distal femoral cutting angle supposed to be an equable spectrum...
the objective of this work was to develop a new design of an intake manifold through a 1d simulation. it is quite familiar that a duly designed intake manifold is essential for the optimal performance of an internal combustion engine. air flow inside the intake manifold is one of the important factors, which governs the engine performance and emissions. hence the flow phenomenon inside the inta...
Introduction: Anthropometric studies provide valuable information in different populations. This study was conducted to evaluate the anatomical variations of the normal hip joint among Tehran population, Iran, in comparison with other populations. Methods: This study was carried out on hip joint of 260 patients in all ages and both genders referred to the Department of Radiology at Ebn-e Sina ...
objectives: this study sought to assess the effects of length and inclination of implants on stress distribution in an implant and terminal abutment teeth in an implant assisted-removable partial denture (rpd) using three-dimensional (3d) finite element analysis (fea). materials and methods: in this in vitro study, a 3d finite element model of a partially dentate mandible with a distal extens...
Background : Under-reporting of energy intake is a common problem among nutrition-related epidemiological studies. The aim of the present study was to determine the effect of under-reporting of energy intake on the estimate of nutrient intake. Materials and methods : 901 subjects aged >16 years were enrolled. Food intake was assessed using a 24-hour food recall questionnaire. Basal metabolic r...
statement of problem: the gonial angle plays an important role in ensuring a harmonious facial profile. changes in this angle especially after surgery may be an aesthetic concern for both the patient and the surgeon. purpose: the aim of the present study was to evaluate gonial angle changes after mandiblular setback with the bssro technique and to measure postsurgical relapse two years after su...
Introduction: This study aimed to investigate the interactions of weight change and fruit and vegetable intake with the incidence of metabolic syndrome (MetS) among adults. Materials and Methods: This study was conducted within the framework of the Tehran Lipid and Glucose Study (TLGS) among 1915 adults during 8.9 years of follow-up. Dietary data were assessed using the food frequency questionn...
Abstract Background: The purpose of this study was to evaluate the significance of the Q angle with respect to the patella position. We assess the correlation between the Q angles (calculated by clinical exam) in different positions and CT indices (with more impression on TTTG). Method: Atotal number of 68 knee joints of 50 cases entered the study. Clinical examination was used to m...
