Background. Dual energy X-ray absorptiometry (DXA, DEXA) is one of many ways of measuring bone mineral density (BMD). Considering the fact that it is possible using DXA analysis to distinguish metal elements from bone, this method seems to be optimal in the assessment of bone mineral density in the area of an inserted implant. The aim of our study was to examine the usefulness of DXA examinatio...

Abstract. Osteoporosis is called a silent disease because bone fragility manifests itself to the patient only in an advanced state, through fracture and pain. Medical industry leaders recognize that current golden standard diagnostic method, densitometry, or Dual Energy X-ray Absorptiometry (DEXA), may not always be sufficient assess patient’s real risk of [1]. Indeed, pathological alterations ...

UNLABELLED Distraction osteogenesis can be used to replace segmental bone loss when treating malignant bone tumors in children and adolescents. These patients often receive cytotoxic chemotherapy as part of their treatment regimen. The effect of cytotoxic drugs on the cellular processes during distraction osteogenesis and the structural and mechanical properties of regenerate bone is unknown. W...

Background . Reverse arthroplasty is an effective method of treating severe injuries and diseases the shoulder joint. In cases osteoporosis, defects deformities glenoid, there are risks incorrect installation instability components endoprosthesis. literature data, problem osteoporosis in endoprosthetics joint methods its solution rather poorly reflected, which was reason for this study. The aim...

BACKGROUND The purpose of this study was to assess the relationship between bone mineral density and insertion/deletion (I/D) angiotensin converting enzyme polymorphism (ACE) in hypertensive postmenopausal women. METHODS Blood and urine samples from the study subjects were analyzed for calcium metabolism related parameters. Densitometry studies were conducted in the lumbar spine (L2 to L4). T...

Exercise has shown little success in mitigating bone loss from long-duration spaceflight. The first crews of the International Space Station (ISS) used the "interim resistive exercise device" (iRED), which allowed loads of up to 297 lb(f) (or 1337 N) but provided little protection of bone or no greater protection than aerobic exercise. In 2008, the Advanced Resistive Exercise Device (ARED), whi...

OBJECTIVE To determine the effect of teriparatide on new bone formation in a rat model of distraction osteogenesis. METHODS The experimental study was conducted at the Aga Khan University Hospital, Karachi, in November-December 2010, and comprised male Sprague-Dawley rats weighing 250gm each who were allocated to two treatment groups, teriparatide and saline, both given subcutaneously for 7 w...

background different clinical and epidemiological studies using dual-energy x-ray absorptiometry have shown an increased prevalence of low bone mineral density in patients with inflammatory bowel diseases.the aim of this study was to assess the correlation between bone density and the disease activity in patients with ulcerative colitis. methods in this cross-sectional study, 52 patients with u...
