Recently published data for fracture in human humeral cortical bone are analyzed using cohesive-zone models to deal with the nonlinear processes of material failure. Such models represent the nonlinear deformation processes involved in fracture by cohesive tractions exerted by the failing material along a fracture process zone, rather than attributing all damage to a process occurring at a sing...

We studied the relationship between the subperiosteal bone collar and forty metaphyseal lesions in specimens obtained at autopsy from ten infants who died with evidence of abuse. The fracture specimens were studied with high-detail radiography and light microscopy. The typical morphological pattern was a fracture extending through the primary spongiosa adjacent to the chondro-osseous junction. ...

Introduction Fractures are quite common, especially among the elderly. However, they can increase in prevalence in younger ages too if the bone health is not good. This may happen as a result of bad nutrition. Methods A customized, retrospective review of available literature was performed using the following keywords: bone health, nutrition, and fractures. Results Insufficient intake of ce...

BACKGROUND Calcium supplements increase bone mass in children, but the effect does not persist once supplementation is discontinued. OBJECTIVE The objective of this study was to determine whether milk intake during childhood and adolescence, when controlled for current calcium intake, is associated with adult bone mass (ie, bone mineral content), bone mineral density, and the incidence of ost...

There are differences in bone health between ethnic groups in both men and in women. Variations in body size and composition are likely to contribute to reported differences. Most studies report ethnic differences in areal bone mineral density (aBMD), which do not consistently parallel ethnic patterns in fracture rates. This suggests that other parameters beside aBMD should be considered when d...

INTRODUCTION Iatrogenic patellar fracture is reported as a complication of patella procedures, such as medial patellofemoral ligament reconstruction, reconstruction of the anterior cruciate ligament of the knee using bone-patellar tendon-bone technique, and resurfacing the patella in total knee arthroplasty. CASE PRESENTATION A 65-year-old lady with right patella fracture was treated with ope...

Patients who sustain an acetabular fracture are a challenge to the orthopedic surgeon because of the inherent difficulty of the fracture and its treatment. Acetabular fractures in elderly patients add another level of complexity with additional co-morbidities associated with age such as osteoporotic bone, the fracture type and comminution, medical conditions, and insufficient bone stock to supp...

Fracture prevention is a critical component of managing osteoporosis, which is not longer defined by T-score alone. The internationally validated World Health Organization Fracture Risk Assessment Tool (FRAX) provides the clinician a state-of-the-art tool for predicting patients at greatest risk for fracture. The FRAX tool takes into account country, bone mineral density of the hip (when availa...

Bisphosphonates are powerful drugs. Their ability to reduce the risk of osteoporotic fractures has saved thousands of people from becoming a fracture patient. Osteoporosis is due to an imbalance in the maintenance remodeling of the skeleton. This remodeling is different from the repair processes following fracture or bone surgery. Because research on the use of bisphosphonates has mostly focuse...

neglected, untreated and delayed femur neck fractures are commonly encountered and the treatment dilemma arises especially when the patient is physiologically young and osteosynthesis is the preferred option. controversy exists in the current literature as the various head salvage surgeries like valgus subtrochanteric osteotomy, non-vascularized fibular bone grafting, muscle pedicle bone grafti...
