A fastener has a first end portion engageable with a bone portion. A connecting member for connecting the plate to the fastener in any one of an infinite number of positions along the slot includes a recess for receiving a portion of the plate. The recess has an interference fit with the portion of the plate received in the recess. A nut engages the second end portion of the fastener to apply a force to cause the interference fit between the plate and the recess.

Why it's free to use

  • Filed April 22, 1996 and granted February 9, 1999. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended April 22, 2016.
  • A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by April 22, 2018.
  • We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
