Above, proximal and IPs of the Hand 1 (a) second, (b) third (c) fourth and (d) fifth ray in lateral view (all to scale). Below, box-and-whisker plots of curvature in H. naledi (e) intermediate phalanges (n=14) and (f) proximal phalanges (n=11), quantified as the first poly...
Based on visual inspection, probe penetration, X-ray, and CT examination of 100 cortical bone trajectories, the excellent rate of 40 trajectories on four dry specimens was 95%, while that of 60 trajectories on six wet specimens was 88.7%. Conclusion: Use of lumbar constant anatomical structures...
Operative intervention was performed immediately, within 1 day after the incident. The first surgery focused on debriding nonviable tissue and performing a ray amputation on the index finger, as the local infection and MESS score was 9, with high likelihood association of amputation. We identified ...

An add- itional idea, the "X-ray" hypothesis, proposed that the degree of binocular convergence maximizes the amount of visual information received, and that primate visual perception is improved by forward facing eyes, since binocularity confers the power of 'seeing through' clutter in the ...
This technique involves closed reduction and the insertion of three hollow compression screws in an inverted triangle formation under X-ray guidance. However, the accuracy of freehand nail placement is limited by variations in surgeon experience, fracture types, and individual hip anatomy, as well ...
A large proximal tarsal element comprising the fibulare, intermedium and tibiale + lateral centrale develops in the ankle. In P. vitticeps e-j, a very similar sequence of cartilage elements in the hand (e-g) develop relative to A. uniparens with the added intermediate stage of seeing...

due to the positions of the eyes relative to the objects viewed. This binocular disparity provides information that the brain uses to estimate depth in the visual scene [6–9]. An additional idea, the "X-ray" hypothesis, proposed that the degree of binocular convergence maximizes the amount ...
The evolution of fishes to tetrapods (four-limbed vertebrates) was one of the most important transformations in vertebrate evolution. Hypotheses of tetrapod origins rely heavily on the anatomy of a few tetrapod-like fish fossils from the Middle and Late
