Periprosthetic plating system including plate with system for retaining tension on a cable
A system, devices and methods are provided for facilitating stabilization of periarticular fractures. The system includes a compression plate and one or more of a cerclage cable for encircling the bone and securing the compression plate to the bone, a crimp lug for securing the cable in tension relative to the bone and/or a plate, and a supplemental plate coupled to the compression plate and adapted to receive bicortical or unicortical bone screws to further secure the compression plate relative to the bone. In addition, the system includes a cable tensioner for temporarily retaining the cable in tension and then applying a tension to the cable until a desired compression is effected between a plate and bone and while a cable retaining structure is secured to the cable to retain the applied tension on the cable. Also provided is a jig for use with plates for minimally invasive fracture stabilization.
1. A plating bone system, comprising:
a) a metal plate including an upper surface, a lower surface, sides along said upper and lower surfaces, a width extending between said sides, a first cable passage extending widthwise through said plate,
b) a cable for stabilizing a bone, said cable having a first end provided with a stop structure, and a second end; and
c) a spring provided in said first cable passage for abutting said stop structure at said first end,
wherein when said second end of said cable is advanced through said first cable passage, tensioning of said cable causes said stop structure to compress said spring within said first cable passage.
2. A plating system according to claim 1 , wherein:
said spring is a coil spring.
3. A plating system according to claim 1 , wherein:
said cable extends through said spring.
4. A plating system according to claim 1 , wherein:
said plate includes a second cable passage extending widthwise through said plate and longitudinally displaced relative to said first cable passage,
said cable extending through said second cable passage.
5. A plating bone system, comprising:
a) a metal plate including an upper surface, a lower surface, sides along said upper and lower surfaces, a width extending between said sides, a first cable passage extending widthwise through said plate,
b) a cable for stabilizing a bone, said cable having a first end provided with a stop structure, and a second end; and
c) a spring abutting said stop structure at said first end of said cable,
wherein when said second end of said cable is advanced through said first cable passage, tensioning of said cable causes said stop structure to compress said spring.
