Although 25-30 grams of calcium is transported into the fetus during pregnancy, it is suggested that the maternal bone might be kept at the same density as in non-pregnant women by measuring serum or urinary calcium concentrations and calcium regulating hormones simultaneously (Ohara et al. Folia Endocrinol., 1986). In this study, the influence of pregnancy on the maternal bone was investigated...

In man, the dominant right hand is often larger than the nondominant left hand. However, in horses, skeletal asymmetry has not previously been reported. Skeletal asymmetry in the racehorse may influence the way it races and affect the incidence of lameness. The growth in length of the third metacarpal bone (McIII) in the horse has ceased by age 10 weeks (Fretz et al. 1984) and its length should...

A retrospective study was conducted to evaluate the outcome of treatment with alendronate (ALN) for 5 years in postmenopausal Japanese women with an increased risk of fractures. Forty postmenopausal Japanese women with osteoporosis or osteopenia and clinical risk factors for fractures (mean age: 75.4 years) were analyzed; 33 patients were treated with alendronate and 7 were treated with alfacal...

Previous studies have shown a strong correspondence between long bone bilateral asymmetry and reported handedness. Here, we compare the pattern of asymmetry in mechanical properties of the humerus and second metacarpal of Pan troglodytes, recent British industrial and medieval populations, and a broad range of human hunter-gatherers, to test whether technological variation corresponds with late...

A variety of fractures occur at the base of the first metacarpal bone, the best known being that described by Bennett in 1882. A group of more comminuted fractures also involving the carpo-metacarpal joint were later described by Rolando (1910). Transverse fractures at the lower end of the metacarpal bone were mentioned by Roberts (1938) in a review of all fractures occurring in the hand. Much ...

OBJECTIVE The objective of this study was to determine the prevalence and distribution of bone erosions detectable by US in patients with early RA (ERA) in comparison with long-standing RA (LSRA), other erosive diseases and healthy controls. METHODS Thirty patients with ERA and 80 patients with LSRA were consecutively recruited. Thirty patients with PsA, 15 with primary OA, 10 with gout and 2...

Finding an appropriate soft-tissue grafting material to close a wound located over the distal phalanx of the thumb, especially the pulp region, can be a difficult task. A sensate first dorsal metacarpal artery flap, mobilized from the dorsum of the adjacent index finger and used as an island pedicle skin flap, can be useful for this purpose. The pedicle includes the ulnar branch of the first do...
