ABSTRACT:
An interspinous process distraction device includes a male distraction element and a female distraction element, which both have a clamping portion for fixedly pushing and rejecting the interspinous processes and also respectively have a first connecting portion and a second connecting portion connected at the other end of the clamping portion. Here, the first connecting portion and the second connecting portion are paired for blocking with each other so as to form the interspinous process distraction device capable of having an opposite rotation. Besides, through clamping two interspinous processes which stress the nerve by the male distraction element and the female distraction element and rotating them to oppositely rotate, the two interspinous processes can therefore be moved to be in alignment as the normal condition.
