1 Expose fractured rib
Expose the rib to allow a minimum of three screws
on each side of the fracture.
Remove nonviable bone.
Removal of the periosteum is not required.
Caution: Avoid significant muscle division, to preserve
respiratory function.
2 Measure rib t ickness
Insert the caliper tip through a small incision at the
superior border of the rib and measure rib thickness.
Add 2 mm to the measurement to determine
appropriate screw length and drill bit with stop.
Caution: Avoid damage to the nerve and vessel bundle
along the inferior border of the rib.
MatrixRIB. table fixation of normal and osteoporotic ribs—plates.
Indications
The ynthes MatrixRIB Fixation ystem is indicated for
the fixation and stabilization of rib fractures, fusions and
osteotomies of normal and osteoporotic bone.

3 Approximate rib segment and select plate
Approximate broken rib segments using forceps.
5b Cut plate
If necessary, cut the plate to length to match the template.
Caution: Use a minimum of three screws on each side
of the fracture.
6 Contour plate
Bend the plate to match the template, using the
bending pliers, if necessary
Caution: Avoid sharp bends, reverse bends, bending the
plate at a screw hole, and notching or scratching the plate.
7 Position plate
Use the plate holding forceps to hold the plate over the
fracture, allowing a minimum of three screws on each
side of the fracture.
Caution: Insert the forceps from the superior border of
the rib, to avoid the nerve and vessel bundle located
along the inferior border of the rib.
4 Cut and contour t e plate template optional
Contour the template to the rib.
5a Select plate
Use the plate template to select the plate, if necessary.

8 Drill
Thread the drill guide into the plate. Drill, using the
2.2 mm drill bit with stop determined in tep 2.
Irrigate during drilling, to avoid thermal damage
to the bone.
Remove the drill guide.
Caution: Do not drill deeper than necessary, to avoid the
risk of pneumothorax.
9a Insert locking screws
Use the depth gauge through the plate to confirm
screw length.
Caution: Do not extend the tip of the depth gauge
too far beyond the posterior cortex of the rib.
9b Insert the locking screw through the plate.
Tighten until secure.
Caution: The tip of the screw should not extend more
than 1 mm beyond the posterior cortex.
10a Drill and place remaining screws
Verify proper reduction of the fracture.
Insert a second screw on the opposite side of the
fracture, as in teps 8 and 9.
10b Insert remaining screws in the same manner.
