From the sign of the induced CD, two helical screw-sense inversions were found by changing the chiral monomer content. The Ising model for chirally interacting chiral-achiral random copolymers can ...

BACKGROUND: This study was performed to determine if the accuracy of screw placement was improved with use of the Herbert-Whipple cannulated screw compared with use of the AO/ASIF cannulated screw ...

Accurate percutaneous screw placement for scaphoid fractures remains technically challenging. Research now shows that using computer-assisted navigation may help surgeons with screw positioning ...

Evidence from a major study published in Lancet showed most scaphoid waist fractures achieve union with casting alone, reserving an indication for surgery for a limited number of cases, a ...

First, the SLIC Screw has a joint that allows rotation between the scaphoid and lunate. Second, the screw is designed to be removed in six to nine months, protecting the soft tissue repair and ...

At the same time, Bradley Smith mentioned that a screw was to be inserted in his scaphoid bone (one of the wrist bones, see pics below), to mend the injuries and help him get in better shape sooner.
