- A: Extra-articular (Transverse)
- B: Unicondylar fracture
- subdivided into lateral condyle sagittal, and medial condyle
saggital and coronal;
- deforming forces: gastrocnemius
- of special importance is B III (
Coronal or Hoffa fracture),
where only soft tissue attachment is the posterior capsule,
which behaves like a large loose fragment in the joint;
- C: Bicondylar Fracture
- there is shortening & anterior displacement of shaft caused by
unrestricted pull of the quadriceps and hamstring muscles along w/
displacement caused by gastrocnemius, which causes posterior
angulation and rotation;
- described as noncomminuted supracondylar (T or Y), supracondylar frx;
- w/ type C 3:
- note that the
condylar blade plate may be contraindicated;
- consider instead a
butress plate;
- need to restore condylar width, hence consider avoiding lag screws,
and always consider need for bone graft;
