Differential rod contouring can be used to achieve derotation
of vertebral segments. Contour the concave rod with extra
kyphosis which can apply derotational moments in the axial
plane and also pull the apical vertebrae dorsally.
Contour the convex rod with less thoracic kyphosis to
push down on the convex side of the vertebral bodies,
thus displacing them anteriorly and decreasing the
rib prominence.

ROD PLACEMENT
The EXPEDIUM VERSE Implant has a polyaxial head drag
feature which allows for alignment of the screw head
positioning, facilitating rod insertion.
Use the Rod Clamp to insert the rod into the openings of the
EXPEDIUM VERSE Implants.
Place the rod into the openings of the EXPEDIUM VERSE
Implants using the sagittal profile of the rod to closely
approximate the position of the polyaxial screw and begin
sequential rod capture. Start by loosely capturing the rod
distally and proximally while working towards the apex.
(FIGURE 29)
An attempt should be made to capture the rod
in all EXPEDIUM VERSE Screw tabs prior applying any
correction forces.
