Effect of fatigue loading on impact response of rat ulna
… loading was applied in vivo on the right ulnae of sixteen rats (Sprague-Dawley, Charles River), and the left served as contralateral control. The animals were divided into two groups: one day of rest before they were sacrificed and the other seven days. Afterwards, the ulnae were harvested …

Angular limb deformities affecting the canine radius and ulna : classification using the center of rotation of angulation method
We hypothesized that 1) antebrachial ALDs would be more complex with respect to multiplicity in chondrodystrophic dogs, and 2) more complex ALDs would exhibit a higher incidence of concurrent joint radiographic disease. Medical records from 2006 to 2013 were searched and cases included of dogs …

A pilot study on stature estimation of the South African male population using the post mortem Lodox® Xmplar-dr imaging device at the Salt River Forensic Medico-Legal Laboratory
… long bone maximum lengths i.e. humerus, radius, ulna, femur and tibia of the bodies were digitally measured using the integrated Lodox® software. Lodox® image scan measurements found that the humerus, femur and tibia were the most statistically significant correlators of stature, individually. …

BIOMECHANICS OF THE DISTAL RADIOULNAR JOINT WITH A MALALIGNED DISTAL RADIUS
… the kinematics and loading of the distal radial ulnar joint (DRUJ) before and after simulated distal radius malalignment would provide important new information to the treatment of these fractures. Furthermore, an investigation into the effect of soft- tissues would further the biomechanical …

Determining mechanical properties and type of fracture of osseous tissues from spent hens
… and torsion test procedures on the radius, ulna, humerus, femur, tibia, and tarsometatarsus of 72 week old caged layers. Shear and bending properties were determined to evaluate the effects of juvenile protein feeding sequence, body size, and cage profile on the strength of these bones. Body …

A comprehensive analysis of long bone curvature in Neanderthals and modern humans using 3D morphometrics
… analysis to quantify bone curvature (femur, ulna, radius) in Neanderthals, Upper Palaeolithic and recent modern humans, 2) compare adult bone curvature between these populations, and 3) test hypotheses on the effects of climate, body size, and activity patterns on curvature. Comparisons …

Subtrochlear sclerosis evaluation for medial coronoid disease detection and dynamic distal ulnar ostectomy for reduction of disease progression in Labrador retriever puppies
… the early radiographic detection of subtrochlear ulna sclerosis (STS), which could successfully predict the development of medial coronoid disease (MCD) in four-month-old puppies, and at the same time perform distal dynamic ulnar ostectomy (DDUO) to prevent or reduce disease development. Study …

Influence of Oral Contraceptives on Bone Adaptations to Isokinetic Strength Training in Young Women
… were run between NOC and OC groups. Increases in ulnar BMD (p < 0.01 for all limbs) and BMD of the trained total hip (OC, p < 0.001; NOC, p < 0.05) occurred irrespective of contraceptive status. Positive changes in EI were conflicting, occurring in the trained ulna for the NOC group (p < 0.05), …

Ex vivo and in vitro effects of omega-3 fatty acids on joint health in sows and gilts
… cartilage was obtained from the humeral-ulnar joints of Yorkshire x Landrace market sized gilts. Explants were harvested from the humeral-ulnar joints within 8 h of slaughter. Explants were allocated to culture plates and cultured in 1 mL of DMEM:F12 medium for 24 h with 10% fetal bovine …

Numerical modeling of cortical bone adaptation due to mechanical loading using the finite element method
… fi nite element (FE) models of actual rat ulna from micro computed tomography (micro-CT) images. The external adaptation process is implemented in the model by moving the surface nodes of the FE mesh along the normal direction based on an evolution law characterized by two parameters: one …

Mechanically-Induced Osteocyte-Th17-Cell Signaling and Osteoclastogenesis
… Therefore, in vivo fatigue loading of rat ulna was performed to identify inflammatory cytokines associated with targeted bone remodeling. Experimental results showed that fatigue loading of rat ulna results in:|1.Bone tissue microdamage.|2.Increased RANKL-percent positive osteocytes and …

Evolutionary dynamics of avian and non-avian limb morphology
… shown that the relative sizes of the humerus an ulna are closely related to flight style in various clades of birds. This pattern suggests a tight link between locomotor function and wing skeletal morphology, and potentially a constraint on the evolution of these elements. In contrast, non-avian …

Study of the microstructure and mechanical properties of hummingbird wing-bones
… which included the humerus, radius, and ulna. Upon examining the images produced via micro-computed tomography and scanning electron microscopy, it was found that trabecular bone was present, suggesting the mechanical advantages of the trabeculae were required. Nano-indentation results …

''ARROWMAN'' : an analysis of a possible medieval cold case from Poulton, Cheshire
… was a well healed fracture of the right distal ulna. The individual represented by SK535 could have been wounded by an arrow carrying the Type M7 bodkin arrowhead, possibly during the English-Welsh border skirmishes during this period.

Frakturen der langen Röhrenknochen beim neugeborenen Kalb
… vor allem solche von Humerus und Radius/ Ulna, aber auch fünf der Tibia. Letztere im Bereich der proximalen Metaphyse lokalisierte Frakturen (5) heilten ohne Verband allein durch Boxenruhe ab. Die bei den restlichen 91 Kälbern angewendeten operativen Techniken bestanden aus …

Effects of Ovariectomy and Anatomical Position on the Compact Bone As Seen in Three Month Summer Ovine Model
… and had their right and left radii and ulna removed. The left radial-ulna bone was then divided into 6 anatomical locations: craniolateral, cranial, craniomedial, caudolateral, caudal, and caudomedial. With the bone divided into different anatomical sectors, microradiographs were …
