Experiments and analyses were performed to determine the cause of a nonlinear force-deflection response observed in four-point flexural fatigue of beams of cortical bone machined from the mid-diaphysis of the equine third metacarpus. Observable grooves which formed on the beam surface at supports and load noses were found to be the primary cause of the nonlinearity. An additional geometric nonl...

The Gorham-Stout syndrome is a rare condition in which spontaneous, progressive resorption of bone occurs. The aetiology is poorly understood. We report a patient with osteolysis of the metacarpal bones in both hands due to an increased number of stimulated osteoclasts. This suggests that early potent antiresorptive therapy with bisphosphonates may prevent local progressive osteolysis.

Congenital brachymetatarsia most commonly involves the fourth ray and may be combined with metacarpal shortening. Now, many reports demonstrated the usefulness of distraction osteogenesis for lengthening of the metatarsals by using an external distraction device. In this article, we treated shortening fourth metatarsal by bone lengthening using the internal distraction device. This technique ha...

Skinner and colleagues (Research Article, 23 January 2015, p. 395), based on metacarpal trabecular bone structure, argue that Australopithecus africanus employed human-like dexterity for stone tool making and use 3 million years ago. However, their evolutionary and biological assumptions are misinformed, failing to refute the previously existing hypothesis that human-like manipulation preceded ...

Scaphoid fracture with ipsilateral metacarpal fracture dislocation is very rare. A unique case of this injury is reported. It is important to be aware of this fracture pattern so that appropriate evaluation and treatment can be instituted. Thorough clinical and radiographic examination at the initial presentation of the patient is the key to identify uncommon combination of injuries.

In many horses with proximal suspensory desmitis, radiopharmaceutical uptake (RU) in the proximal aspect of the third metacarpal (metatarsal) bone is normal. Increased RU reflects an enthesopathy, which may influence both treatment and prognosis.

Age at menopause has been found to be associated positively with bone mineral density, and age at menarche has been found to be associated negatively with bone mineral density. However, there have been few studies on the relations of timing of menopause and length of the reproductive period with bone mineral density. The purpose of this study was to examine the relations of timing of menopause ...
