A
Implant Insertion
Instruments Used:
1. Anvil Attachment (1)
Remove the Bead Tipped Guidewire and insert the DynaNail into the medullary canal,
rotating the Targeting Frame to help advance the Implant.
If additional force is required to advance the Implant, slide the Anvil Attachment onto
the Targeting Frame (A) and strike the Anvil with a mallet (B). The Anvil Attachment
can be removed after the DynaNail Implant is inserted.
TECH TIPS
• Do NOT strike any other part of the frame besides
the Anvil Attachment.
• Hold at least one side of the anvil down in the slot
to ensure that it does not slip out and fall.
• Pay attention to rotation of Nail Implant during insertion.
Too medial of an entry point combined with internal
rotation may affect the position and purchase
of the calcaneal PA screw.

Nail Placement Guidelines:
Position the lateral-to-medial calcaneal screw hole as proximal
as possible in the calcaneus (after the Compressive Element
is stretched in the following step). In this proximal position,
the lateral screw gains optimal purchase by targeting the longest
possible screw in the widest part of the calcaneus. This proximal
position also countersinks the DynaNail as far as possible within
the calcaneus. Countersink the distal end of the DynaNail Implant
6 mm in the calcaneus (Refer to X-Ray). The Outer Body will
translate distally up to 6 mm as the Compressive Element
unloads post-operatively.
TECH TIP
• To achieve optimal lateral-to-medial screw positioning after the
Compressive Element is stretched, insert the DynaNail Implant
until the lateral-to-medial screw hole is aligned with the subtalar
joint (refer to X-Ray). In this case when the Compressive Element
is stretched to the maximum 6 mm (Step 10), this screw hole
will translate distally by 6 mm, placing it in the optimal
proximal position within the calcaneus.
