Bone strength is influenced by bone geometry, density, and bone microarchitecture, which adapt to increased mechanical loads during growth. Physical activity (PA) is essential for optimal bone strength accrual; however, less is known about how sedentary time influences bone strength and its determinants. Thus, our aim was to investigate the prospective associations between PA, sedentary time, and bone strength and its determinants during adolescence. We used HR-pQCT at distal tibia (8% site) and radius (7% site) in 173 girls and 136 boys (aged 9 to 20 years at baseline)...

PURPOSE: Early diagnosis of attritional wear of the flexor pollicis longus (FPL) tendon is essential in preventing subsequent tendon rupture. There are currently few objective methods of assessing FPL attrition. We hypothesized that color Doppler imaging could visibly detect FPL tendon attrition, and analyzed our results. METHODS: We evaluated ultrasound imaging of the contact between the FPL tendon and a volar locking plate using the real-time B-mode and Doppler waveforms of the FPL tendon using the continuous Doppler wave mode in 40 patients who underwent fixation of the distal volar locking plate for distal radius fracture...

Periostin is an extracellular matrix protein, and in bone is expressed most highly in the periosteum. It increases bone formation through osteoblast differentiation, cell adhesion, Wnt signalling and collagen cross-linking. We hypothesised that serum periostin would be high at times of life when cortical modeling is active, in early adulthood and in older age, and that it would correlate with cortical bone measures, bone turnover and hormones that regulate cortical modeling. We conducted a cross-sectional observational study of 166 healthy men and women at three skeletal stages; the end of longitudinal growth (16-18years), peak bone mass (30-32years) and older age (over 70years)...

Simultaneous Monteggia injuries of the elbow and ipsilateral fracture distal radius with epiphyseal injury both bone are a unique case. A unique case of a Type I Monteggia fracture equivalent with ipsilateral fracture distal radius with epiphyseal injury (Salter-Harris Type II) in a child is reported. We describe the management of this unique fracture and discuss the possible mechanism of injury. We have highlighted a rare combination of injuries. Early recognition and prompt surgical intervention can lead to a satisfactory outcome even in these complex injuries...

INTRODUCTION: There is no algorithm for the management of joint stability in midflexion up to now. Change in the joint line (JL) is considered to be the primary cause, although it only determines the extension gap. The purpose of this study was to determine the influence of the posterior condylar offsets (PCO), which defines the flexion gap, on midflexion instability. MATERIALS AND METHODS: Forty-two knee joints (38 patients) were included in this study, patients undergoing navigated total knee arthroplasty due to primary osteoarthritis of the knee...

Objective, design and methods: Roux-en-Y gastric bypass (RYGB) has proved successful in attaining sustained weight loss but may lead to metabolic bone disease. To assess impact on bone mass and structure, we measured areal bone mineral density at the hip and spine by dual-energy x-ray absorptiometry, and volumetric BMD (vBMD) and bone microarchitecture at the distal radius and tibia by high-resolution peripheral quantitative CT in 25 morbidly obese subjects (15 females, 10 males) at 0, 12 and 24 months after RYGB...

Several cross-sectional studies have shown that impairment of bone microarchitecture contributes to skeletal fragility. The aim of this study was to prospectively investigate the prediction of fracture (Fx) by bone microarchitecture assessed by high-resolution peripheral computed tomography (HR- pQCT) in postmenopausal women. We measured microarchitecture at the distal radius and tibia with HR-pQCT in the OFELY study, in addition to areal BMD with dual-energy X-ray absorptiometry (DXA) in 589 women, mean ± SD age 68 ± 9 years...

BACKGROUND: Various medical fields rely on detailed anatomical knowledge of the distal radius. Current studies are limited to two-dimensional analysis and biased by varying measurement locations. The aims were to 1) generate 3D shape models of the distal radius and investigate variations in the 3D shape, 2) generate and assess morphometrics in standardized cut planes, and 3) test the model's classification accuracy. METHODS: The local radiographic database was screened for CT-scans of intact radii...

INTRODUCTION: Distal radius fractures accounts for around 15% of all fractures diagnosed and treated in the emergency rooms. These fractures usually result secondary to high velocity injury such as a motor vehicle accident or fall on an out stretched hand. In the elderly, it is a common fragility fracture. Volar Locking Compression Plates (LCP) is effective devices for fixation of the distal radius fractures. There is a lacuna with regard to literature on the 2.7 mm volar LCP and the current study retrospectively assesses the postoperative radiological outcomes...

INTRODUCTION: Fracture of the distal end of radius represents the most common fracture of the upper extremity accounting for 16-20% of all fractures. Plating is now emerging as the gold standard for management of distal radius fractures due to increased rate of complications such as malunion, subluxation/dislocation of distal radio-ulnar joint or late collapse of fracture. Procedures such as closed reduction and cast immobilization, ligamentotaxis with external fixator and percutaneous pin fixation are no longer acceptable...

This study examined the degree to which various mechanical, biochemical and dietary factors are related to non-weight bearing bone properties in 172 healthy peri-pubertal children (11.7±2.0 years). Dominant radial speed of sound (rSOS) was measured by transaxial quantitative ultrasound at distal radius. Potential modulating factors included somatic maturity offset (years from age of peak height velocity), grip strength, forearm lean cross-sectional area (CSA), physical activity, nutritional intake and amino-terminal cross-linking propeptide (NTx), reflecting bone resorption...

Madelung deformity is an abnormality of the distal part of the forearm due to a growth arrest in the distal radial physis creating an increase of the radial tilt angle associated with a dorsal subluxation of the distal ulna in most cases. It is a rare condition which represents only 1.7% of hand deformities being characterized by the presence of an abnormal structure, Vickers ligament, that tethers the distal radius to the lunate bone. Although it is believed to be a congenital disorder, the symptoms are absent till late childhood...
