The incidence of femoral neck fractures increases exponentially with rising age. Young patients are rarely affected but when they are it is mostly due to high energy accidents, whereas older patients suffer from femoral neck fractures by low energy trauma due to osteoporotic changes of the bone mineral density. Treatment options have not essentially changed over the last few years. Non-operative treatment may be a choice in non-dislocated and impacted fractures. Due to the high risk of secondary fracture displacement prophylactic screw osteosynthesis is recommended even in Garden type I fractures...

Osteoclast, a huge coenocytes,originates from mononuclear macrophages or monocytic series hematopoietic precursor cell, plays an important role in the progree of bone resorption. Formation and abnormal activity of osteoclast may cause osteoprosis, rheumatoid arthritis and aseptic loosening after arthroplasty. Therefore, osteoclast is the target for treating these disease. At present, a lot of study on formation of osteoclast were reported, but the study on how to identify and degradation of bone tissue is not yet reported...

OBJECTIVE: To study the optimal cut-off value of phalangeal radiographic absorptiometry (RA) to identify osteoporosis in postmenopausal women. METHODS: A total of 650 postmenopausal women were recruited in this study. Bone mineral density (BMD) at lumbar spine and left proximal femur neck was measured by dual-energy X-ray absorptiometry (DXA) as the standard method to identify postmenopausal osteoprosis. Phalangeal bone density was estimated by the use of RA. Optimal cut-off value of phalangeal RA was determined using a ROC curve for screening the ostreoporosis cases...

Teriparatide is an only available bone anabolic drug in practice. It is a N-terminal fragment of parathyroid hormone (PTH) . Mode of actions of teriparatide is pharmacological but not physiological as it is administered to patients with osteoporosis. Physicians need to understand the fact that treatment with teriparatide is not just like a hormone replacement. They also should administer teriparatide to their patients after rigorous evaluation of its clinical superiority to other anti-osteoprosis drugs, because it is not classified as a first-line drug...

BACKGROUND: Assessment of osteoporotic fracture risk is based primarily on bone mineral density (BMD) measurements using dual X-ray absorptiometry (DXA). METHODS: However, recent evidence indicates that the method is insufficient for accurate individual risk assessment; in addition to methodological inaccuracies related to DXA, the mechanical strength of bone is influenced not only by low BMD but also by other factors that are not captured by DXA. RESULTS: DXA-based BMD can provide information on the amount of bone but does not elucidate bone structure, which is significant for bone mechanical strength and for fracture risk...

Spinal Cord Injury (SCI) is damage to spinal cord, which is categorized according to the extent of functional loss, sensation loss and inability of the subjects to stand and walk. The patients use two transportation systems including orthosis and wheelchair. It was claimed that standing and walking bring some benefits such as decreasing bone osteoporosis, prevention of pressure sores, and improvement of the function of the digestive system for SCI patients. Nevertheless, the question of wether or not there is enough evidence to support the effect of walking with orthosis on the health status of the subjects with SCI remains unanswered...

Acute lymphoblastic leukemia (ALL) is the most common childhood malignancy. Skeletal abnormalities have been described in association with ALL including osteoprosis and bone fractures. Different factors including the disease itself or soluble products of malignant cells and treatment agents like cytotoxic drugs, methotroxate, corticosteroids and radiotherapy may be responsible for defective bone homeostasis in these patients. Orthopedic conditions and pain may be the first manifestation of acute leukemia and it is important for physicians to recognize the skeletal manifestation of acute childhood leukemia because of a delay in diagnosis has adverse effect on survival...

Zingerone, a major component found in ginger root, has been known as anti-mutagenic and anti-carcinogenic activities that are often associated with its anti-oxidative and anti-inflammatory activities. In recent studies, we examined molecular mechanism of zingerone treatment on pro-inflammatory NF-kappaB activation via the redox-related NIK/IKK and MAPK pathways. Action mechanism of zingerone on NF-kappaB signaling was investigated in aged rat kidney and endothelial cells. The results showed that zingerone had not only the antioxidant effect by constitutive suppression of ROS, but also anti-inflammatory effects by suppression of nuclear factor (NF)-kappaB activation in aged rat...

Both androgen and estrogen play important roles in bone metabolism. As estrogen has a potent inhibitory effect on bone resorption, bone turnover increases in postmenopausal osteoprosis caused by estrogen deficiency. Treatment with selective estrogen receptor modulator (SERM) as well as hormone replacement therapy (HRT) improve bone turnover increased in postmenopausal women to normal range before menopause. Although the decrease of androgen level with aging is involved in pathogenesis of male osteoporosis, the detailed mechanism remains to be clarified...

Background. Thanks to modern methods of diagnosis, treatment and rehabilitation, we currently possess the means to counteract the consequences of osteoprosis and limit the number of falls in osteoporotic patients. Material and methods. Based on an original questionnaire, we analyzed a group of 54 patients (48 women and 6 men) under treatment for osteoporosis in order to assess the level of physical activity and the reasons for its reduction in patients with osteoporosis, to determine the situations mostly endangered by falls, and to survey the opinion of patients regarding the need for a rehabilitation program to prevent falls...

Ovariectomy (OVX) in animal models is an accepted method to simulate postmenopausal osteoprosis. Vascular endothelial growth factor (VEGF) has been recently shown to play an important role during endochondral bone formation, hypertrophic cartilage remodeling, ossification, and angiogenesis. We hypothesized that reduced VEGF expression in bone contributes to OVX-induced bone loss and tested it in a miniature pig model and in vitro using human osteoblasts. Seventeen primiparous sows (Göttingen miniature pigs) were allocated to two experimental groups when they were 30 months old: a control group (n = 9) and an OVX group (n = 8)...

The experimental model of ovariectomy (OVX) has been well used as a model for studying the pathogenesis of postmenopausal osteoporosis. It is known that the hematopoietic environment in the bone marrow is altered leading to the up-regulation of osteoclastogenesis after the estrogen withdrawal. We discuss the possibility whether this alternation of lymphocyte-lineage cells could trigger off a risk factor for the periodontal disease.

Successful kidney transplantation corrects many of the metabolic abnormalities associated with development of renal osteodystrophy, but despite a well-functioning graft, osteopenia, remains prevalent in adult and pediatric kidney recipients. The factors that affect the bone mineral density (BMD) and the long term course of BMD after transplantation in children is still unknown. We performed a cross sectional study to determine BMD in 83 recipients who received living renal allotransplants in Mansoura Urology & Nephrology Center between 1981 and 2002 (mean age at transplantation 13...
