Acceptable Reduction for Pediatric Both Bone Forearm Frx



- See: Technique of Reduction

- Discussion:
    - initial considerations:
          - angular / rotational deformity: (growth will not correct rotational deformity)
          - age
          - distance from physis
          - direction of angulation
          - amount of deformity
    - bayonette apposition
          - generally bayonette opposition will require operative reduction (either closed with a Kapandji K wire levering technique or in some situations, an open reduction and fixation with K wires will be required);
          - historically, overriding of a both bones forearm fracture was acceptable if...
                 - there was no deviation of radius and ulna toward each other;
                 - there was no encroachment of the interosseous space;
                 - pt is less than 10 yrs of age;
    - in pts < 6 yrs of age:
          - upto 15 deg of angulation is acceptable, especially if frx is distal;
          - 5 deg of rotation may also be acceptable;
    - between ages of 6-10 yrs:
          - less than 10 deg of angulation should remodel especially if frx is close to distal epiphysis;
          - bayonet apposition may be acceptable, although end to end apposition is preferred;
          - acceptable angulation is less than 15 deg, however, even more angulation may be preferable to resorting to open reduction;
                 - this is especially true if the reduction allows physiologic pronation and supination;
    - pts > 12 yrs of age:
          - no angulatory or rotational deformity is considered acceptable;
          - more aggressive treatment is required, including open reduction and compression plating may be required;

- Displaced Distal Third Frx:
    - angulation up to 20-25 deg during first ten years is OK;
    - angulation > 10 deg is unlikely to correct after 10 yrs
