objective: the aim of this cross-sectional analytic study was to evaluate the diagnostic efficacy of panoramic-based indices of the mandible (mental index-mi, mandibular cortical index-mci and panoramic mandibular index-pmi) and to determine their correlation with bone mineral density (bmd) of the femoral neck and lumbar vertebrae (l2-l4) in order to assess the possibility of using these parame...

Objective To evaluate the correlation between radiographic parameters of the proximal femur with femoral neck fractures or transtrochanteric fractures. Methods Cervicodiaphyseal angle (CDA), femoral neck width (FNW), hip axis length (HAL), and acetabular tear drop distance (ATD) were analyzed in 30 pelvis anteroposterior view X-rays of patients with femoral neck fractures (n = 15) and transtr...

Our previous work on mechanisms of femoral neck fracture demonstrated that the bone mineral density of femoral neck and Ward's triangle in patients with femoral neck fracture is less than those in the normal population [4]. Under similar loading condition, the stress can easily reach the ultimate strength level of bone and lead to fractures. The results indicated that osteoporotic patients with...

OBJECTIVE The purpose of this work was to analyze the relationship between intensity and duration of physical activity and composite indices of femoral neck strength and bone-mineral content of the femoral neck, lumbar spine, and total body. METHODS Physical activity was assessed by accelerometry in 143 girls and 150 boys (mean age: 9.7 years). Measurement of bone-mineral content, femoral nec...

PURPOSE The aim of this study was to investigate the correlation between bone mineral density (BMD) and arterial stiffness as a preclinical atherosclerosis criterion. MATERIALS AND METHODS Carotid and femoral artery Doppler ultrasonography and arterial stiffness measurements were performed on 113 female patients referred for BMD measurements. RESULTS The cross-sectional compliance and cross...

Associated ipsilateral femoral neck fractures have been reported to occur in 1% to 9% of femoral shaft fractures. The associated femoral neck fracture is often nondisplaced, and the diagnosis is delayed or missed in up to one-third of cases. It is essential to carefully evaluate the femoral neck in all patients sustaining high-energy femoral shaft fractures. Although there are a number of diffe...

During hip resurfacing arthroplasty, excessive valgus positioning or surgical technique can result in notching of the femoral neck. Although mechanical weakening and subsequent fracture of the femoral neck are well described, the potential damage to the retinacular vessels leading to an ischaemic event is relatively unknown. Using laser Doppler flowmetry, we measured the blood flow in 14 osteoa...

Floating hip injuries and ipsilateral femoral neck and shaft fractures are rare. Additionally, the simultaneous occurrence of these injuries is extremely rare, and only one case report of the simultaneous occurrence of these injuries has been published. Here, we report the case of a patient with ipsilateral acetabular and femoral neck and shaft fractures following a suicide attempt. The patient...
