purpose low bone mass is a major health concern among young women nowadays due to sedentary lifestyle and lack of calcium rich food intake. therefore there is an increase in the incidence of lbm among young university women so our main purpose of study was to compare effects of exercise program and calcium supplements on bone mass in young women. methods this single blinded, cross sectional stu...

Postmenopausal women with vertebral fractures have abnormal bone microarchitecture at the distal radius and tibia by HR-pQCT, independent of areal BMD. However, whether trabecular plate and rod microarchitecture is altered in women with vertebral fractures is unknown. This study aims to characterize the abnormalities of trabecular plate and rod microarchitecture, cortex, and bone stiffness in p...

OBJECTIVES The purpose of this study was to examine the effects of long-term wheel-running on tibia bone properties in T2DM Otsuka Long-Evans Tokushima Fatty (OLETF) rats. METHODS Ten five-week-old male OLETF rats were used as experimental animals and 5 Long-Evans Tokushima Otsuka (LETO) rats as controls. Half of OLETF rats performed daily voluntary wheel-running for 17 months (OLETF-EXE), wh...

background: exogenous phytase enhances the utilization of plant phytate phosphorus in poultry. objectives: in the present study the effects of exogenous phytase was investigated on tibia bone characteristics of white quail. methods: in a 2x2 factorial arrangement, eighty, 11-day old unsexed chicks were randomly divided into 4 treatments of 20 replicates. all birds received one of four experimen...

BACKGROUND In total knee arthroplasty (TKA), cement penetration between 3 and 5 mm beneath the tibial tray is required to prevent loosening of the tibia component. The objective of this study was to develop and validate a reliable in vivo measuring technique using CT imaging to assess cement distribution and penetration depth in the total area underneath a tibia prosthesis. METHODS We defined...

BACKGROUND The bone remodeling sequence after bone fracture changes the concentrations of biochemical bone markers, but the relationships of fracture size and of healing time to changes in biomarkers are unclear. The present pilot study was undertaken to determine the changes found in serum bone markers after plate osteosynthesis of closed distal tibial and malleolar fractures during a study pe...

AIM The effects of Spinal Cord Injury (SCI) on bone in paralyzed areas are well documented but there are few data for the importance of the level of injury in the decrease of mechanical strength in paralyzed legs. The aim of the present study was to describe bone loss of the separate compartments of trabecular and cortical bone in spinal cord injured men and to compare possible changes in mecha...

Osteoporosis in laying hens has been a production and welfare concern for several decades. The objective of this study was to determine whether differing opportunities for exercise during pullet rearing influences long-term bone quality characteristics in end-of-lay hens. A secondary objective was to assess whether differing opportunities for exercise in adult housing systems alters bone qualit...

Additional bone and cartilage are formed if transforming growth factor-beta is injected into the periosteum of calvariae or long bones. To investigate this further, transforming growth factor-beta 2 was injected into the periosteum of the tibia of 3-day-old, 3-month-old and 2-year-old rabbits. In all instances, there was an increase in proliferation of the cells of the cambial layer of the peri...

BACKGROUND Large bone defect in infant or small patients has been little reported and the management of such a patient is difficult. Considering the little knowledge of this area, we present this special case of a successful single-cortex fibula graft for the treatment of a large tibia bone defect in a 2-year-old patient to share our experience. CASE SUMMARY A 2-year-old male patient presente...
