Background: Effects of estrogen on bone metabolism and its protective role on prevention of osteoporosis are well documented. However, the efficacy of estrogen treatment on bone healing is not well investigated. The drug can be delivered both systemically or locally to the bone with differences in concentrations and side effects. The aim of this study was to investigate the effect of lo...
Introduction: Aneurysmal bone cyst is a rare primary or secondary osseous tumor which is frequently seen in the mataphysis of long bones. Its treatment mostly is curettage and bone graft. Case Report: The patient is a 23 year old man with a left femoral diaphysial and juxtacortical aneurysmal bone cyst who underwent extended curettage after diagnostic work-up and preoperative ambolizatio...
Introduction: Magnesium is an essential mineral in bone formation. This nutrient incorporates in bone metabolism and enhances bone mineralization. This study was designed to assess the effect of magnesium supplementation on alkaline phosphatase , osteocalcin, and also callus formation in women with long bone fracture. Methods: In this double-blind randomized placebo controlled trial, 32 women ...
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...
the objective of the current study was to determine the anatomical features of the auditory ossicles inhamster. twenty temporal bones from 10 adult hamsters, weighing 275-300 g were used. after dissectingthem, the features of the ossicles were assessed with an ocular micrometer and photographed by astereomicroscope. finally, all data were evaluated and analysed using the sigma statt software. t...
Distraction osteogenesis (DO), firstly introduced to the medical world by Russian scientist Ilizarov for long bone lenghtening in orthopedics can be considered as an appropriate substitute in the treatment of maxillofacial deformities. Natural events occuring during the repair of a fractured bone segment not only lead to the desired bone length but also prevent from the undesired disadvantages ...
Guided bone regeneration (GBR) is a reconstructive procedure of alveolar ridge using membranes. This procedure is indicated when there is no sufficient bone for implantation, or in the case of optimal implant installation for esthetic or functional needs. GBR can be performed before implant placement, when there is not enough bone for initial stability of implants and less predictable outcomes ...
ewing's sarcoma is a relatively common malignant bone tumor that typically occurs in long bone diaphyses of adolescents and young adults of 10-30 years old. often times, all ewing's sarcoma of bone have radiographic abnormalities. diagnosis is usually delayed and can be misdiagnosed as osteomyelitis. bone to bone metastasis occurs, but soft tissue retro bulbar metastasis is rare. this...
Progressive loss of bone mineral density around the femora! component of total hip replacement continues to pose a threat to long term prosthetic survival. A linear study was undertaken to measure bone mineral density on a monthly basis following total hip arthroplasty in 11 male patients. The opposite femur was used as the control measurement. Bone mineral density was unchanged at two mo...
