BIOMECHANICS OF THE DISTAL RADIOULNAR JOINT WITH A MALALIGNED DISTAL RADIUS
Distal radius fractures are the most common fractures in humans and frequently have suboptimal outcomes, fostering considerable discussion with regard to treatment. This body of work was based on the postulate that quantifying the biomechanics, specifically the kinematics and loading of the distal …

Fracture of the distal radius - outcome, primary surgery and treatment of malunion
A consensus protocol for treatment of distal radius fractures (DRF) has been developed to aid clinicians in treatment decision making. The protocol was evaluated in Paper I using a validated subjective outcome instrument, DASH in 518 consecutive patients. A good final subjective result was achieved …

Using HR-pQCT and finite element analysis to inform clinical assessment of distal radius fractures
Distal radius fractures (DRFs) are commonly treated non-operatively with cast immobilization; however, there are no standardized clinical practice guidelines to direct optimal duration of immobilization following a DRF. Finite element (FE) modelling coupled with high-resolution peripheral …

Outcomes after percutaneous leverage reduction and pinning for irreducible metaphyseal fractures of distal radius in children
BACKGROUND: Irreducible metaphyseal fractures of distal radius in children have been treated by open reduction. The authors have used percutaneous leverage reduction with a small osteotome and fixed with percutaneous pinning to treat irreducible fractures. HYPOTHESIS: Percutaneous leverage …

Predicting off-axis bone strength of the distal radius using high-resolution peripheral quantitative computed tomography based finite element modeling
Distal radius fractures are one of the most common types of fractures to occur in older adults. Bone strength (e.g., failure load) of the distal radius can be estimated using finite element (FE) models generated from high-resolution peripheral quantitative computed tomography (HR-pQCT) images; …

High-Resolution peripheral Quantitative Computed Tomography Based Finite Element Modelling of Distal Radius Strength: Assessing Effect of Heterogeneous Material Properties and Scan Site
… (HR-pQCT) based finite element (FE) models of distal radius sections explains 66% of variance in experimental testing results on intact forearms under fall configuration testing. However, this FE model employs a somewhat simplistic modeling approach in that it does not account for variations in …

MUSCULOSKELETAL STRENGTH, FALL AND FRACTURE RISK IN EARLY POSTMENOPAUSAL WOMEN
… status over the first year following a distal radius fracture (DRF), and evaluate differences in fall and fracture risk factors in women over the age of 50 years with a DRF compared to their non-fractured peers. Methods: Two cohorts of participants volunteered in two sub-studies of the …

The role of neuromuscular performance on bone strength and properties in the forearm and lower leg of children
… activity in determining bone properties at the radius and tibia in children. Methods: 37 boys and 42 girls (mean age 10.5; SD 1.6y) had their dominant forearm and lower leg imaged using peripheral quantitative computed tomography (pQCT) and high resolution pQCT (HR-pQCT). Bone mass, density, …

Psychological Factors and Health-Related Quality of Life in Upper Extremity Conditions
… patients’ emotional experiences following distal radius fracture. A qualitative study (n = 14) explored patients’ early emotional responses, identifying four themes: prior psychological and life context, injury appraisal, social support, and loss of independence with adaptive coping. A …

Epiphyseal fractures of the distal humerus
This dissertation discusses distal humeral epiphyseal injuries in children, i.e. lateral condylar fractures, medial condylar fractures, fracture-separation of the distal humeral epiphysis and T-condylar fractures. Medial and lateral epicondylar fractures, being apophyseal, are excluded. The …

Quantification of bone using a 3.0 tesla clinical magnetic resonance scanner
… and chemical properties.The MR data from distal radius and tibia demonstrated good correlation with pQCT data (e.g. Figure 8-2 & Figure 8-3) and were also able to differentiate between HBM-affected and control populations (e.g. Figure 8-26). The MR data from lumbar vertebrae also …

A cross-sectional study of radial and tibial ultrasonography between different ethnic and physically active groups
… ultrasound (Sunlight MiniOmni®) of the distal radius and mid-shaft tibia was measured in 132 male students aged 18-25 (69.22±11.04kg, 1.74±0.08m) as well as quadricep strength and anthropometrics. An aim of the study was to determine if frequency and type of physical activity affect …

Forearm Loading (FAL) Study: A Recreational Gymnastics Intervention within a Physical Education Setting
… (Tb.N), and trabecular thickness (Tb.Th) at the distal radius and tibia. Independent sample t-tests were used to determine differences in demographics and DXA measures and MANOVA was used to assess HR-pQCT at baseline and follow-up. With-in group differences were determined using paired sample …

Ex vivo and in vitro effects of omega-3 fatty acids on joint health in sows and gilts
… joints of each pig post-mortem. The right fused radius/ulna were analyzed using computed tomography (CT). CT scans of the radius/ulna from gilts revealed no differences for cortical width and bone density. Sows fed PUFA had greater cortical width of the proximal ulna (P<0.05) and decreased …

Bone speed of sound in overweight and normal-weight girls and adolescents
… Omnisense™), bone SOS was measured at the distal radius and mid-tibia. No differences were found between groups in daily total energy, calcium or vitamin D intake. However, all groups were below the recommended daily calcium intake of 1300 mg (Osteoporosis Canada, 2008). Adolescents were …

Bone Mass from Childhood to Adulthood
… and young adulthood measurements for distal radius BMC and BMD varied between 0.35 and 0.64 and for femoral neck BMC, BMD and bone area it varied between 0.37 and 0.65. A childhood fracture in men was associated with a low BMC Z-score (–0.4 (95% CI –0.6, –0.1)) and low BMD Z-score …
