Measure the distance between the cranial rib and either the
thoracolumbar junction or the chosen caudal rib to deter-
mine the appropriate Extension Bar size.
– Measure to the thoracolumbar junction when planning a
rib-to-ilium or rib-to-lumbar lamina construct.
– Measure to the caudal rib when using a rib-to-rib con-
struct.
The measurement in centimeters will correspond to the cor-
rect Extension Bar size. For example, if the distance is
determined to be 7 cm, use an Extension Bar marked with a
7. Implants are identified from 4–13 in 1 cm increments.
