The Mini External Fixator – Surgical Technique
Indications, Features and Components
Indications
•
•
•
•
•
•
Complex fractures of phalanges and metacarpals
Displaced intra-articular fractures
Segmental bone loss
Open fractures not allowing stable internal fixation
Fractures with associated complex soft tissue injuries
Tumour resections
Features
•
•
•
•
Module fits in the Modular Hand System
Low clamp profile
Compatible with the small External Fixator 107.982
Choice of threaded Kirschner wires of 1.25mm or 1.6mm dia.
with corresponding clamps
• Radiolucent Carbon-Fibre Rods
• Allows sequential clamping of two Kirschner wires in the clamp
Components
1.25mm
1.6mm
Clamp Bodies for 1.25mm and 1.6mm wires
Allow sequential tensioning of Kirschner wires to reduce the operation
time. The clamp-body nuts are captured.
Slender design contributes to overall low-profile frame for improved
patient comfort.
Connecting Clamp, 3.0/3.0mm dia.
Allows connection of 3.0mm Carbon-Fibre Rods for the treatment of
displaced intra-articular fractures. An additionally available 3.0/4.0mm
Connecting Clamp allows bridging to the small Synthes® External Fixator
for the treatment of complex hand and distal radius fractures.

Carbon-fibre rods
Lightweight for patient comfort.
Radiolucent for improved intra- and postoperative radiographic
visualization.
1.25mm
1.6mm
Threaded Kirschner wires with trocar tip, in two sizes
Provide more stability and better hold in cortical bone.
Eliminate need to predrill, for reduced operative time.
1.25mm and 1.6mm diameters optimise adaptation to fracture patterns
and patient anatomy.
Angle
Allows lateral application of pins while maintaining a dorsal frame construct, as determined by the fracture pattern and surgeon’s preference.

Surgical Technique
1
Insert first Kirschner wires
Insert one threaded Kirschner wire through the double drill sleeve
1.25/1.6 in each fragment. Place the first two Kirschner wires as close as
possible to the fracture in each fragment.
2
Add clamps and rods
Connect the appropriate clamp to each Kirschner wire through the open
hole of the clamp:
• 1.25mm Kirschner wires – Clamp Body for 1.25mm wires
• 1.6mm Kirschner wires – Clamp Body for 1.6mm wires
Insert a 3.0mm rod to connect the clamps.
Reduce the fracture. Lightly tighten the nuts of both pin and rod clamps
to provide sufficient stability for radiography and final fracture reduction.

3
Insert remaining Kirschner wires
Insert the two remaining Kirschner wires as far as possible from the
fracture, using the remaining clamp holes as guides.

Secure all clamp nuts
Tighten the nuts on both clamps, using the clamp holder to avoid
fracture displacement. Cut the Kirschner wires, if necessary.
