Abstract
Instruments for applying tension to a securing device, such as a cable or wire, for securing bones in place and fastening implants, such as plates, to bones. In some forms, the tensioning instrument is configured with minimal parts for ease of manufacturing and allowing single use applications. The instrument may include a pretensioning mechanism for applying desired preload before connecting a cable to be tensioned to the instrument. The instrument may be sized and configured to remain attached to a tensioned cable while other cables are connected to a bone. In another form, the instrument may be expandable to remove any slack from the securing device and apply tension thereto.
