Your question is broad beyond the scope of the question in this case. ALL unstable fractures must be fixated either with pins, external fixation or ORIF. I assume you may be asking whether growth plate activity affects the decision in a child. First, I am assuming the individual here was in his late teens at least. Second, as i said, we need to know the location of the fractures. Here are some guidelines according to age for ulanr and radial fractures:
- 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;
