Stress fractures are overuse injuries of bone that affect elite athletes and military recruits. One response of cortical bone to stress fracture is to lay down periosteal callus. The objectives of this study were to determine if material properties are different among bones with different stages of stress fracture callus, at both a callus site and at a distal site. Cortical specimens were mecha...

Background: In patients who have sustained a traumatic brain injury with an associated extremity fracture there is often a clinical perception that the rate of new bone formation around the fracture site is increased. In this study, we made a rat model of femoral fracture to investigate the serum factors changes in vivo. We examined the effects serum factors on fracture healing and the molecula...

Introduction: Nasal bone fractures are one of the most common problems in patients who are referred to otolaryngology centers. We aimed to evaluate physical examination, sonography and conventional lateral nasal bone radiography in patients with nasal bone trauma and its relation to intra-operative findings. Methods: This prospective study was performed on 200...

The association between hip fracture and reduced bone mineral density is well documented, with reduced bone mineral density predisposing to fracture. However, it is unknown whether an association exists between the magnitude of bone density lost and the severity of the hip fracture sustained. One hundred forty-two patients (96 women, 46 men) with a mean age of 74 years (range, 49-92 years) who ...

INTRODUCTION Sonic Hedgehog (SHH) is a new signalling pathway in bone repair. Evidence exist that SHH pathway plays a significant role in vasculogenesis and limb development during embryogenesis. Some in vitro and animal studies has already proven its potential for bone regeneration. However, no data on the role of SHH in the human fracture healing have been published so far. METHODS Seventy-...

of vitamin K were not affected by fractures in its acute phase. Bone formation markers did not change during the acute phase of hip fracture. Bone resorption markers increased on the third day. Biochemical markers of bone turnover were not affected for at least 48 h after fracture. Therefore, the values of those measurements during the first 48 h after fracture appear to reflect bone metabolism...

The trabecular and cortical compartments of bone each contributes to bone strength. Until recently, assessment of trabecular and cortical microstructure has required a bone biopsy. Now, trabecular and cortical microstructure of peripheral bone sites can be determined noninvasively using high-resolution peripheral quantitative computed tomography (HR-pQCT). Studies that have used HR-pQCT to eval...

Head injuries are the most serious injuries in the term of morbidity and mortality. This study was conducted in Government Medical College mortuary among the 200 post mortem cases of road traffic accident victims over the period of one year from 1st October 2014 to 30th September 2015. All the cases coming during the study period were included in the study. The objective is to find out pattern ...

The nasal bone is among the most frequently broken facial bone due to all types of trauma and is the most frequently fractured facial bone due to motor vehicle collisions. This study reports the results of anterior-posterior impacts performed on male cadavers using a free-falling impactor with a flat impacting surface. The force at fracture onset was determined using an acoustic emission sensor...

INTRODUCTION Fracture healing is a complex biological process involving inflammation, granulation, callus formation, and bone modeling/remodeling. Optimal fracture healing results in complete restoration of bone structure and function to the pre-fracture levels. However, some fractures are associated with a high risk of delayed union, non-union and other complications. This leads to significant...
