1. The skeletal effects of simple bed rest and re-ambulation were studied in a consecutive series of 34 patients (aged 18-60 years) hospitalized with low backache due to protrusion of a lumbar intervertebral disc. The bone mineral content of the second, third and fourth lumbar vertebrae was determined by dual-photon (153Gd) absorptiometry immediately after admission to the hospital, at the end ...

We quantitatively studied the role of periosteum and bone marrow-endosteum during lengthening in 18 growing rabbits, comparing four surgical procedures: 1) periosteum and bone marrow preservation, 2) periosteum preservation, bone marrow destruction, 3) periosteum destruction, bone marrow preservation, 4) periosteum and bone marrow destruction. An external fixator was set on one femur, the other...

1. The skeletal effects of physical training were studied in a controlled trial involving 31 healthy women (aged 50-73 years) with previous Colles' fracture of the forearm. The bone mineral content of the lumbar spine and both distal forearms was measured by dual-photon (153Gd) absorptiometry. 2. The participants were allocated to either a physical exercise group or a control group. The former ...

OBJECTIVE To determine the effectiveness of vitamin D supplementation for improving bone mineral density in children and adolescents and if effects vary with factors such as vitamin D dose and vitamin D status. DESIGN Systematic review and meta-analysis. DATA SOURCES Cochrane Central Register of Controlled Trials, Medline (1966 to present), Embase (1980 to present), CINAHL (1982 to present)...

BACKGROUND Calcium supplements increase bone mass in children, but the effect does not persist once supplementation is discontinued. OBJECTIVE The objective of this study was to determine whether milk intake during childhood and adolescence, when controlled for current calcium intake, is associated with adult bone mass (ie, bone mineral content), bone mineral density, and the incidence of ost...

Background: Calcium supplements increase bone mass in children, but the effect does not persist once supplementation is discontinued. Objective: The objective of this study was to determine whether milk intake during childhood and adolescence, when controlled for current calcium intake, is associated with adult bone mass (ie, bone mineral content), bone mineral density, and the incidence of ost...

Reattachment of tendon to bone has been a challenge in orthopedic surgery. The disparate mechanical properties of the two tissues make it difficult to achieve direct surgical repair of the tendon-to-bone insertion. Healing after surgical repair typically does not regenerate the natural attachment, a complex tissue that connects tendon and bone across a gradient in both mineral content and cell ...

INTRODUCTION Cycling has been associated with decreased bone mass during adolescence. Calcium (Ca) and vitamin D (VitD) intake are associated to bone mass and may be important confounders when studying bone mass. AIM To clarify the effect that Ca and VitD may have on bone mass in adolescent cyclists. METHODS Bone mineral content (BMC) and density (BMD) of 39 male adolescents (20 cyclists) w...

Raloxifene, a selective estrogen receptor modulator, is used for prevention and treatment of osteoporosis in postmenopausal women. Raloxifene use in male subjects is increasingly considered and a few clinical studies of its effect on bone turnover have already been performed. The aim of the present study was to investigate the effects of raloxifene on the skeletal system of healthy mature male ...
