Headless Compression and Twist-Off Screws
Surgical Technique
K-Wire Placement
The osteotomy is then stabilized in a uni-cortical
application, such as a distal Chevron osteotomy, by
advancing the 0.9 mm K-Wire across the osteotomy
site until the tip is visible. Retract the wire slightly, so
the tip is below the articular cartilage (Figure 4). Verify
k-wire position via fluoroscopy.
Note: It is recommended to subtract 3-4 mm from
the depth gauge measurement to avoid penetrating
the articular cartilage with the distal tip of the
screw. For example, if the measurement is 20 mm
then select the 16 mm screw.
Tip: When using a screw longer than 28 mm for
oblique applications, it may be beneficial to use a 0.9
mm x 105 mm k-wire.
Tip:
For hammertoe applications, a sterile double
tipped 0.9 mm x 152 mm k-wire is available for order.
