Radius-ulna diapheyseal fracture

Stabilization by dinamizable fixator 


1. Look at the fracture and the way it is displaced 


2. Connect the fixator to the overlapped fracture by means of two pins. Check the fixator has been 
connected with the cylinders close together. 


3. Rotate the C1-C2 couple holding the C cylinder side by means of wrenches, distracting the fracture.


4. Once the fracture is distracted, check the extensions of the clamps are securely tightened (1), and use the 
clamp to perform the final fracture reduction on the 
other planes. 


5. Achieve a correct fracture reduction BEFORE adding any other stabilizing element.


6. Once the correct fracture reduction is achieved, stabilize the fracture as required.


Once a bone callus developed, and dynamization can be useful for its maturation, the fixator can afford for this.  
Untighten the D1-D2 couple on the D side of the cylinder, and move the D2 nut far from the D1 of the amount you want the fixator to allow for axial motion (typically, 2-3 mm). Then, untighten the C1-C2 couple, move it some mm far from the C side of the cylinder, and tighten it again. Rotate the C1-C2 couple counterclockwise, holding the C side of the fixator, until the D2 nut reaches the D1 nut. Lock both couples against both sides of the fixator. Once locked, the fixator will stay as you leave it (static or dynamic).
