Cubitus Varus


- See: Baumann's Angle

- Discussion:
    - cubitus varus is the most common complication following supracondylar frx,
    - orginally, etilogy of cubitus varus was thought to occur because of growth disturbance of distal humeral epiphysis;
            - this may be true but is uncommon;
    - current thinking is that it stems from malreduction of frx, with medial displacement, internal rotation, and extension of the distal fragment;
            - this then permits distal fragment to tilt into varus;
    - cubitus varus produces a cosmetic deformity but little function deficit;
    - during reduction, a small amount of medial or lateral displacement or small amount of anterior or posterior angulation may be tolerated, but any malrotation is not acceptable;
     - rotation is verified under flouro w/ AP view, lateral view, & oblique views;
     - if reduction is not be obtained, there may be soft-tissue interposition which mandates open reduction;
