- Discussion:
- bicondylar frx w/ distal oblique shaft frx;
- these frx have bicondylar frx along w/ dissociation of diaphysis from metaphysis;
- if the medial plateau fragment is intact, this frx can be treated with placement of a lateral plate and and
Ex Fix to prevent displacement;
- 35% of type VI fractures are open and 86% has extensive soft tissue injuries;
- Management:
-
circular wire fixators:
- can be used to stabilize the diaphyseal-metaphyseal segment;
- circular wire fixators are unable to reliably stabilize the articular surface;
- articular fixation requires either lateral plating or insertion of cancellous lag screws inserted over washers;
- this fixation should precede application of the fixator;
- if possible screws should be inserted from lateral to medial or from anterior to posterior;
-
complications:
- pin tract infections can lead to devastating knee sepsis and therefore pins needs to be inserted at least 2 cm from the joint line;
- in the study by JS Reid et al, the authors determined in a cadaver study that proximal tibial
transfixation wires away from the tib-fib joint are likely to be extra-articular if kept
greater than 14 mm away from the subchondral bone.
- in the region of tib-fib joint, safe distance is difficult to determine since it cannot be known preop which knees have torn septum;
- loss of fixation following frame removal;
- note that in complex fractures, the frame may have to be left in place for up to 3 months to ensure
maturation of fracture healing (gradual loss of reduction may occur with premature frame removal);
