this study was performed to evaluate the results of 14 years of application of ilizarov method in treatment of infected non-:union:s of tibia and femur in patients with severe trauma and battlefield wounds. seventeen patients with long bone non:union: (14 were with infected non:union: of tibia out of whom two were associated with tibial bone defects and 3 with infected non-:union: of femur) wer...

This study investigated the effects of a 14-day spaceflight on bone mass, density and microarchitecture in weight bearing (femur and humerus) and non-weight bearing (2(nd) lumbar vertebra and calvarium) bones in the context of ovarian hormone insufficiency. 12-week-old Fisher 344 rats were ovariectomized 2 weeks before flight and randomized into one of three groups: 1) baseline (n = 6), 2) grou...

OBJECTIVE To determine, through bone histomorphometry in femoral neck, whether there are differences in the cancellous bone of the proximal femur from female patients over 60 years old who had femoral neck fracture and similar patients who did not have such fracture. METHODS We analyzed the trabecular part of the femur of 13 female patients, aged over 60 years old, by the bone histomorphometr...

Figure Legend: Figure 1 Bone Increased bone in a female B6C3F1/N mouse from a chronic study. The medulla of this femur has been obliterated by increased amounts of bone. Figure 2 Bone Increased bone in a female B6C3F1/N mouse from a chronic study (higher magnification of Figure 1). There is a mix of mineralized and unmineralized bone in the medulla of the femur. Figure 3 Bone Increased bone in ...

Background: Osteoporosis one of the postmenopausal symptoms is characterized by bone loss. There is a link between excessive reactive oxygen species (ROS) formation, estrogen deficiency due to cessation of ovarian function and bone loss. Free radicals are responsible for causing osteoblast apoptosis and reducing osteoblastogenesis in bone remodeling. Vitamin E is a potent antioxidant with the a...

Radiation therapy can result in bone injury with the development of fractures and often can lead to delayed and nonunion of bone. There is no prevention or treatment for irradiation-induced bone injury. We irradiated the distal half of the mouse left femur to study the mechanism of irradiation-induced bone injury and found that no mesenchymal stem cells (MSCs) were detected in irradiated distal...

Osteoporosis (OP) in spinal cord injury (SCI) patients is a secondary process in which numerous factors are involved. Diagnosing OP and the threshold for fractures in this population, based on bone mineral density (BMD) measured by double energy X-ray absorptiometry (DXA), is still a challenge. The aim of this study was to evaluate bone mineral loss by DXA, its relationship with body compositio...

BACKGROUND Stress shielding of the proximal femur has been observed in a number of conventional cementless implants used in total hip arthroplasty. Short femoral-neck implants are claiming less interference with the biomechanics of the proximal femur. The goal of this study was to investigate the changes of bone-mineral density in the proximal femur and the clinical outcome after implantation o...
