Features and Indications
Features
– Two designs: large (round) and small (oval)
– 316L stainless steel and titanium-6% aluminum-7%
niobium alloy
– Slotted center hole allows screw angulations up to 70°
– Small recess at the top end of the washer facilitates
screwdriver insertion
The Synthes Spherical Washer distributes the screw load over
a large area of the cortical surface of the bone, making it
ideal for use in weak, osteoporotic bone. Its recess is deep
enough to fully countersink the screw head. Spherical Washers
can be used with Synthes cannulated screws 6.5 mm to
7.3 mm in diameter.
Notes on use
– To position the washer flush against the bone, with the
recess below the cortex, use a 13.0 mm Cannulated Drill
Bit (351.27) to overdrill the cortex. When drilling, use the
17.0 mm / 15.0 mm Protection Sleeve (357.530) to protect
the soft tissue
– Before placing the washer in position, thread the appropriate
screw through the Spherical Washer. Use a screwdriver to
drive the screw into the bone
Indications
Synthes Spherical Washers are intended to prevent a screw
head from breaking through the cortex of the bone, by
distributing the forces / load over a large area, when used for
fracture fixation of large long bones and bone fragments.
In addition, Spherical Washers are intended to prevent
projection of the screw head, when the screw must be
inserted at an acute angle (e.g., in ankle arthrodesis).
