Predicting peak load of the femoral neck using structural parameters
… cortical bone structures along the length of the femoral neck relate to the peak load of the proximal femur. Structural measurements were taken from microCT images of ten murine right femurs at ten locations along the femoral neck. These specimens were then tested to failure. The major diameter, …

Biomechanical Analysis of Femoral Neck Strength with Respect to Femoral Head Core Decompression
… patients present with avascular necrosis of the femoral head each year in the United States. The current treatment for avascular necrosis is femoral head core decompression which is used to decrease the intraosseous pressure and promote vascular tissue ingrowth. There are two common techniques of …

Interlandmark measurements from lodox statscan images with application to femoral neck anteversion assessment
… were completely visible in both images. Femoral neck anteversion measurement on Statscan images was also explored using 30 dry right adult femurs. This was done in order to assess the feasibility of the algorithm for a clinical application. For this investigation, four methods were tested …

Association Analyses of Estrogen Receptor a Gene Polymorphisms with Bone Geometric Property at The Femoral Neck in Caucasian Nuclear Families
… to examine the importance to the variation of femoral neck geometry. The study group included 1873 subjects from 405 Caucasian nuclear families. I used DXA-derived BMD and bone area to estimate 6 important geometry parameters: cross-sectional area (CSA), endocortical diameter (ED), sectional …

Differences in Bone Mineral Density Among Adolescent Female Tennis Players and Non-Tennis Players
… in this study. Lumbar spine, total hip, femoral neck, and left and right forearm BMD, and BC were assessed using dual-energy x-ray absorptiometry. Total osteoporosis knowledge (TOK) was assessed by the osteoporosis knowledge test. One-way ANOVA was used to assess differences between TP …

Bone fracture toughness of estrogen deficient rabbits
… estrogen deficiency, using fracture toughness, femoral neck fracture and histomorphometric analysis in an ovarectomized rabbit model.;No significant differences were found in fracture toughness, porosity, or femoral neck ultimate strength for any treatment group, which may have be from a lack …

The Relationship of Dietary and Lifestyle Factors to Bone Mineral Density of Healthy Singaporean Chinese Women
… significantly lower baseline lumbar spine and femoral neck bone density than other groups. Perimenopausal women had significantly greater bone loss compared to other groups.</p> <p>In premenopausal women BMI was significantly positively associated with femoral neck bone density while exercise …

Cultural Behaviors and Their Influence on the Proximal Femur: Comparisons of Postural Behavior, Occupation, and Subsistence-Settlement Between a Pre-Contact and Historic Sample
… and postural behavior of the mortuary complex. Femoral neck version is associated with postural behaviors such as squatting and kneeling. The neck-shaft angle is linked to mobility and settlement patterns. Bicondylar angle was explored to see if behaviors had any affect. Allen’s fossa and …

The clinical characteristics, complications and treatment outcomes of patients with osteoporosis at Groote Schuur Hospital
… while there was slight worsening of BMD at the femoral neck (- 0.17%). A fracture whilst on treatment occurred in 10.6% (n=21) of patients. Conclusion: The majority of patients with osteoporosis at Groote Schuur Hospital had a fragility fracture at diagnosis with a vertebral fracture being most …

An examination of age-related differences in lower extremity joint torques and strains in the proximal femur during gait
… the femur. Study 2 examined age differences in femoral strains, and Study 3 examined the sensitivity of strains to individual muscle forces. The results support the idea that older adults walk with reduced contributions from the ankle plantar flexors and increased contributions from the hip …

Assessing the Impact of Femur Morphological Variations on Pediatric Hip Joint Biomechanics Using Statistical Shape Modeling
… features, such as variations in the femoral neck-shaft and anteversion angles. Seven synthetic femurs were generated from the SSM to create SSM-informed MSMs, which were systematically evaluated through kinematics and kinetics analyses in OpenSim. Incorporating the SSM led to slight …

The Influence of Physical Activity on Musculoskeletal Characteristics and Fracture Risk at Growth
… follow-up intervention girls had improved 11% in femoral neck BMC and 8% in tibial cortical bone mass (all p<0.05). Intervention children also improved their muscle strength compared to the controls (all p<0.05). This thesis shows that a long-term PA intervention program in school improves the …

Physical activity and its effect on bone in the short- and long- term perspective.
… bone mineral density (vBMD; g/cm3) of the femoral neck and the third lumbar vertebrae (L3) were calculated from the dual energy X-ray absorbtiometry (DXA) scans. A questionnaire previously used in several studies but modified for children evaluated lifestyle factors. All participants …

High rates of undiagnosed hypoalbuminaemia in orthopaedic trauma patients at a rural hospital
… cohort was found to have hypoalbuminaemia. Femur neck fractures (p < 0.001), intertrochanteric fractures (p = 0.004), tibial plateau fractures (p = 0.034) and polytrauma (p = 0.013) were associated with hypoalbuminaemia. The mean albumin level was lower in HIV-positive patients when compared to …
