Introduction: The human anthropometric characteristics are surveyed in anthropology. Anthropology is used in archeology, rehabilitation and legal medicine. The purpose of this study was to determine femur which has a special place in the science of anthropometry. Methods: To measure the femur, both direct and indirect methods was used. The direct method of measuring the 113 femur in dissection...
Introduction Traumatic dislocation of the hip with ipsilateral fracture neck femur is a rare injury because of the different mechanism of both these injuries. The management of such injuries is a challenge as the chances of nonunion and avascular necrosis of femoral head are very high with fixation methods. We report a case of obturator dislocation of the hip with ipsilateral fracture neck of t...
Cut out or extrusion of the lag screw from the superior aspect of head and neck of the femur is one of the most common and devastating complications of the surgery of the intertrochanteric fractures with DHS. The exact cause of this complications is unknown, but it seems to be related to osteopenia, inappropriate position of lag screw inside head of the femur and inability of DHS to slide insid...
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 (stf)...
We used technetium-99m antimony colloid to visualize the bone marrow of the head of the femur within twenty-four hours after interruption of the blood supply by subcapital osteotomy and section of the ligamentum teres in thirteen rabbits and within twenty-four hours after a subcapital fracture in thirty patients. Of the rabbits, all showed loss of marrow radioactivity over the affected femoral ...

BACKGROUND Hip endoscopy facilitates the treatment of extra-articular disorders of the proximal femur. Unfortunately, current knowledge of proximal femur anatomy is limited to qualitative descriptions and lacks surgically relevant landmarks. PURPOSE To provide a quantitative and qualitative analysis of proximal femur anatomy in reference to surgically relevant bony landmarks. STUDY DESIGN D...
We quantified differences in trabecular volumetric bone mineral density (BMD) of the femoral head between patients with proximal femoral fractures and healthy subjects in the control group by using quantitative computed tomography (QCT) with the purpose of providing guidance for the choice of head screw in the intramedullary nail fixation. Participants suffering from intertrochanteric fractures...
The aim of this study was to analyse the influence of muscle action and a horizontally constrained femoral head on the strain distribution within the intact femur. The strain distribution was measured for three loading configurations: joint reaction force only, joint reaction force plus abductors, and joint reaction force plus the abductors, vastus lateralis and iliopsoas. In each case the stra...
