The intramedullary nail has a longitudinal axis, a proximal end, a distal end, at least one hole that extends transversely to the longitudinal axis and is situated in a plane with a defined diameter to accommodate a locking element, as well as a longitudinal slot extending in the plane parallel to the longitudinal axis. In the unexpanded state of the intramedullary nail the longitudinal slot has a width b, measured perpendicularly to the plane in the region outside of the holes, said slot being maximum 0.6 times that of the smallest defined diameter of the holes.

Intramedullary nail

A device for detachably clamping fastening elements in a surgical fixing or repositioning device. The device may a rod with a longitudinal axis. A first and second pair of clamping jaws may be operably associated with the rod. Each pair of clamping jaws may have a side surface as well as an inner clamping jaw and an outer clamping jaw, which may have indentations forming a channel. The channels may be opened towards the side surface of the clamping jaws. A fastening means may be positioned in the channels by pushing the fastening means into the openings in the side surface in a direction which may be at an angle with respect to the longitudinal axis of the rod. An elastic element may be positioned between the inner and outer clamping jaws of at least one pair of clamping jaws so as to resist movement of the inner and outer clamping jaws with respect to each other as a fastening means is inserted therebetween. A clamping element may engage the rod and may be used to fix the orientation of the clamping jaws and fastening means with respect to each other.

Clamp for external fixation

A device for bone fixation defining at least one through hole extending therethrough, the through hole including first and second through apertures separated from one another by a first resilient element deformable radially outward from the first aperture to expand the first aperture and contract the second aperture, the second aperture being sized and shaped to receive therein a bone fixation element, the second through aperture being smaller in size than the first through aperture, a periphery of the first through aperture comprising at least two substantially circular arcs Band Bwith respective radii Rand Rand respective centers Zand Zlocated at a distance X&#x2267;0 extending transversely to the resilient element whereby the ratio R:Ris in the range between 0.5 and 2.0.
