Musculoskeletal modeling and finite element analysis of the proximal juvenile femur
… Many researchers have analysed the adult femur but little work has been undertaken to understand femoral development in juveniles. Therefore the aim this work was to develop an understanding of the mechanical stresses and strains that the femur experiences during growth.The juvenile femur …

Klinische und radiologische Ergbebnisse der MRP-Revisionsprothese bei verschiedenen Knochendefekten des Femur
… Defekten im Bereich des proximalen Femur ein gutes Behandlungskonzept darstellt. Es konnte nach dem Revisionseingriff kein signifikanter Unterschied im HHS im Vergleich der Gruppen mit unterschiedlichen Knochendefekten am Femur festgestellt werden. Mechanische Komplikationen die auf …

Displaced intracapsular neck of femur fractures: dislocation rate after total hip arthroplasty
… increases up to 22% for THA done for neck of femur fractures. Larger femoral head sizes increase the head-neck ratio and range of motion before impingement, therefore reducing the dislocation rate. Due to the reported increase in dislocation for trauma, some surgeons prefer to do a …

Association of Proximal Femoral Geometry with Osteoporotic Proximal Femur Fracture in Elderly Koreans
… Our study assessed the relationship between femur geometry and hip fracture and evaluated the geometric factors related to hip fracture in elderly Korean. METHODS: 51 proximal femoral fracture patients aged 60 or older were compared to 51 non fracture control subjects aged 60 or older. We …

Locking plates for distal femur fractures does an increased working length improve healing?
Distal femur locking plates have become a very popular means of internal fixation because of their ability to provide stable distal periarticular fixation. In spite of this enthusiasm however several studies have reported significant problems with healing. In the distal femur it is recognized that …

Enhancing the Care Pathway for Older Patients with Fractured Femur: An Action Research Study
… for those who have suffered from fractured femur from admission to hospital until recovery and discharge into the community. A Participatory Action Research (PAR) Cycle was conducted which was guided by the Habermas (1984) Theory of Communicative Action. This PAR Cycle followed three phases …

Changes in 3 Dimensional Microstructures of Subchondral Cancellous Bone of Distal Femur in Early Osteoarthritis
… bone cores were obtained from 4 parts of distal femur of 13 Korean cadaver donors. 6 donors had only grade 2 or 3 cartilage changes in distal part of medial femoral condyle and 7 donors had normal cartilage. These specimens were scanned using high-resolution micro-computed tomography and 3 …

Cortical thickness estimation of the proximal femur from multi-view dual-energy X-ray absorptiometry
… measure the cortical thickness of the proximal femur from multi-view DXA scans. First, a data-driven algorithm is designed, implemented and evaluated. It relies on a femoral B-spline template which can be deformed to fit an individual’s scans. In a series of experiments on the trochanteric …

Various continuum bone remodelling algorithms applied to the proximal femur in two and three dimensions
This study investigates the behaviour of bone when it is subjected to mechanical loading. This is important in fields such as orthopaedics and implant design. Various models of bone remodelling are discussed, and a strain energy based as well as a strain remodelling based algorithm are applied in …

Assessing the Impact of Femur Morphological Variations on Pediatric Hip Joint Biomechanics Using Statistical Shape Modeling
… shape statistical model (SSM) of decedent infant femurs from the Ortolani collection was created using ShapeWorks, capturing key morphological features, such as variations in the femoral neck-shaft and anteversion angles. Seven synthetic femurs were generated from the SSM to create SSM-informed …

Numerical and experimental studies on the mechanical behaviour of the distal femur following total knee arthroplasty
… finite element (FE) models of the distal femur following primary and revision total knee arthroplasty. Pre-arthroplasty models are also developed for comparison. Particular attention is given to how femoral component design and method of fixation impacts the mechanical environment of the …
