Background: The most feared complication of fracture management is non-union. Non-union can be the following types, hypertrophic, oligotrophic, atrophic, and septic. In view a non-union, exchange nailing preferred so routinely performed for non-unions fractures tibia. Case Presentation: Here, we present case an implant failure from atraumatic event in atrophic non-union tibia, which was treated...

poly (lactide-co-glycolide)/bioactive glass/hydroxyapatite (pbgha) and poly (lactide-co-glycolide)/ bioactive glass (pbg) nanocomposite coatings with bone. materials and methods: sol-gel derived 58s bioactive glass nanoparticles, 50/50 wt% poly (lactic acid)/poly (glycolic acid) and hydroxyapatite nanoparticles were used to prepare the coatings. the nanocomposite coatings were characterized by ...

background: old laying hens are more prone to dietary calcium (ca) and phosphorus (p) deficiencies as  they absorb ca and p less efficiently than younger hens. objectives: in a 2×2 factorial design, the influence of diets with two levels of available phosphorus (ap) and phytase enzyme on the laying performance, egg quality and tibia bone characteristics of laying hens at their late 2nd producti...

This paper reports on a sensor for monitoring bone plate strain in real time. The detected bone plate strain could be used for judging the healing state of fractures in patients. The sensor consists of a magnetoelastic material, which can be wirelessly connected and passively embedded. In order to verify the effectiveness of the sensor, a tibia-bone plate-screw (TBS) model was established using...

Objectives Alcohol consumption induces oxidative stress on bone, which in turn increases the risk of osteoporosis. This study determined the effects of vitamin E on bone strength and bone mineral content in alcohol-induced osteoporotic rats. Materials and Methods Three months old Sprague Dawley male rats were randomly divided into 5 groups: (I) control group; (II) alcohol (3g/kg) + normal sal...

Since the cancellous bone displays a fluid-solid coupled porous structure, its solid matrix exhibits excellent osteogenic property and has been extensively used as the scaffold material of tissue-engineering bone. It is the aim of the present paper to examine the transversely isotropic behavior of cancellous bone. Correspondingly, a two-dimension image analysis method was developed to determine...

The goal of this study was to characterize longitudinal changes in bone microarchitecture and function in women treated with an established antifracture therapeutic. In this double-blind, placebo-controlled pilot study, 53 early postmenopausal women with low bone density (age = 56 ± 4 years; femoral neck T-score = -1.5 ± 0.6) were monitored by high-resolution peripheral quantitative computed to...
