Hybrid Fixator—Distal Tibia Frame
1
Insert wires
2
Attach wires to ring using adjustable wire/pin clamps
3
Wrench-tighten clamp-locking nuts
4
Tighten wire-locking nuts
Wrench-tighten the wire-locking nut on the far side of the
ring (A). Finger-tighten on the side to be tensioned (B).
5
Tension wires
Typically, wires are tensioned to 100 kg. Tighten wire-locking
nuts (B) and remove tensioner. To obtain maximum wire
tension, it is recommended after tensioning the second wire,
to retension both wires in the same sequence to obtain the
best frame stability. An alternative method would be to use
two tensioners simultaneously.
6
Insert Schanz screw into distal fragment
Insert through wire/pin clamp.
Note: A third wire can be inserted if the fracture pattern
does not permit Schanz screw placement.

7
Trim, bend and cap wires
Leave 3 cm–4 cm in case retensioning becomes necessary.
8
Construct anterior half-frame
9
Connect ring to half-frame with ring-to-rod clamp
10
Reduce extra-articular component of fracture
Use ring and anterior rod as handles to manipulate fracture.
Tighten ring-to-rod clamp.
11
Add second rod
Connect ring-to-rod clamp and large combination clamp.
Add carbon fiber rod.
