Background: The definite treatment option for osteonecrosis of femoral head (ONFH) is not clearly understood. In current prospective study, we investigated the outcomes of treatment of ONFH with corticocancellous bone autograft. Patients and Methods: 132 hips (96 patients) with ONFH ARCO type II and III were treated with corticocancellous bone autograft from the iliac crest. The pain intensi...
Osteoporotic hip fracture (HF) is a serious global public health problem associated with high morbidity and mortality. Hip bone size (BS) has been identified as one of key measurable risk factors for HF, independent of bone mineral density (BMD). Hip BS is highly genetically determined, but genetic factors underlying BS variation are still poorly defined. Here, we performed an initial genome-wi...
Background: Several studies have suggested higher incidence of osteoporosis in patients with idiopathic scoliosis in comparison with the normal population. The aim of this study was to assess the prevalence of low bone mass among adolescent girls with idiopathic scoliosis.Methods: In this cross-sectional study performed in shafa Hospital in Tehran, Iran during 2011-2012, we recruited fifty-seve...
BACKGROUND Sphingosine 1-phosphate (S1P) has been discovered to be a critical regulator of bone metabolism. Very recently, we found that higher circulating S1P levels were associated with higher rate of prevalent osteoporotic fracture in human. METHODS This was a cross-sectional study of 16 patients who underwent hip replacement surgeries. Bone marrow fluids were obtained during hip surgeries...
BACKGROUND: Hip Dysplasia is a frequent orthopedic disease that is characterized by early joint sublux- ation. The DARthroplasty technique is a two-part process that involves applying bone graft to increase the femoral head coverage with a low morbidity rate and the long term is known results. OBJECTIVES: This study was aimed to investigate the radiograph...
Introduction: Osteoporosis is a disease in skeletal system that is recognized by a lack of bone density and degeneration of bone tissue and can lead to increase the risk of bone fracture or even death. So, this study was conducted to determine the prevalence of decreased bone density in people with common risk factors referred to Al-Zahra Educational-Medical Center in Isfahan City years 2018-20...
In total hip arthroplasty, wear particles generated at articulating surfaces and interfaces between bone, cement and implants have a negative impact on osteoblasts, leading to osteolysis and implant loosening. The aim of this experimental study was to determine the effects of particulate wear debris generated at the interface between straight stainless steel hip stems (Exeter(®)) and three diff...
Background and Aim: For the treatment of osteoporosis, bisphosphonates are commonly used as oral or injectable compounds. This study was conducted with the aim of comparing the effect of oral alendronate with injectable pamidronate on bone density changes in patients with osteoporosis. Materials and Methods: The present study was a semi-experimental based on available evidence that was perform...
introduction: acute lymphoblastic leukemia (all) and non-hodgkin's lymphoma (nhl) are the most common childhood and adolescence malignancy respectively.due to the increasing survival of these children, today late side effects of treatments are important. therapies such as corticosteroids, cytotoxic and radiotherapy effect on bone density and put the child at risk of osteoporosis and pathol...
The adaptive bone remodeling phenomenon in the femur before and after prosthetic total hip joint replacement (THR) was investigated using the three dimensional finite element method. A normal hip joint model which composed of the proximal femur and the pelvic bone including femoral head and acetabular was constructed three-dimensionally by our method reported previously. The simulation model wa...
