Space of Poirier

*Space of Poirier:

Diagram of arcuate ligament (greater arc, zone of fractures and dislocations),
lesser arc (zone of dislocations), and
space of Poirier (vulnerable zone between greater and lesser arcs),

superimposed on wrist radiograph.

>Fibers of radioscaphocapitate ligament (yellow) and
ulnocapitate ligament (purple) interdigitate and form an arclike ligamentous structure, termed the arcuate ligament, in the greater arc region (black line). Note lesser arc that outlines the lunate (dashed red line).
>The scapholunate ligament and lunotriquetral ligament are part of the lesser arc, which does not extend to the distal radius and ulna.

*{The space of Poirier (white arrows) is located between the lesser and greater arcs.}

MEDICAL MIRACLE

Near-vegetative man was back to life after stimulation electrodes were implanted into his skull

A man who was left in a near-vegetative state by a serious assault was able to speak and eat again. The severely brain-injured patient, who is now 38, was unable to communicate, swallow or make coordinate movements for six years, before doctors revived him from this minimally conscious state (MCS) with a revolutionary therapy.

Since his skull was implanted with electrodes to stimulate a deep-lying and undamaged part of his brain, he has improved so dramatically that he can now feed himself, brush his hair and recognize and talk to his parents and doctors. The transformation achieved by the deep brain stimulation (DBS) technique, which is already used to treat Parkinson's disease and some neurological disorder (like Tourrett's Syndrome), has raised hopes that it could offer a way back to consciousness for many people with similarly serious brain damage.
