Mechanism of limitation of pronation/supination of the forearm in geometric models of deformities of the forearm bones.
To clarify the mechanism of limitation of pronation/supination of the forearm associated with the angular deformity of the forearm bones and narrowing of the interosseous space. ⋯ Evaluation of the bone deformities based on understanding this mechanism of limitation of pronation/supination would lead to an appropriate treatment of malunion of the forearm bones.

The effect of hydration on the stiffness of intervertebral discs in an ovine model.
To determine the hydration-over-time behaviour of ovine intervertebral discs and intact joints in a saline bath at body temperature and the effect this has on their stiffness compared to air at ambient temperature. ⋯ It has been shown that there are biomechanical and biochemical similarities between sheep and human intervertebral discs. Despite these similarities, no studies have looked at how ovine intervertebral discs behave over time in a hydrated environment. In humans, hydration levels are an important aspect of intervertebral disc degeneration. There is also a relationship between decreased hydration levels and increased stiffness. This study demonstrates the similarities between human and ovine hydration-over-time behaviour. The importance of intervertebral disc hydration and its effects on stiffness under different modes of loading were also demonstrated and have not been previously shown using the ovine model. In this context, the results from this study provide further support for the use of the ovine model.
