Rod vertebrale for instrumentation osteosynthesis spinal and instrumentation osteosynthesis comprising this rod

摘要

The vertebral rod (1,5..) of constant diameter over its entire length for instrumentation of spinal osteosythesis, to receive the implants (37) for osseous anchorage. The rod has adjusters to vary the radius between the ends. The adjusters fit in a recess (2,23) formed axially in the rod, which extends over at least part of its length. The recess can have at least two axial zones (3,4) of different cross sections.
