Pediatric Ulnar Fracture



- See:
        - Pediatric Both Bone Forearm Fractures
        - Monteggia's Fracture
        - Green Stick Frx
        - Distal Ulnar Physeal Fractures:

- Discussion:
    - pediatric ulnar frx often occur along w/ pediatric both bone forearm frx
            - ulnar frx may be complete or incomplete (green stick frx);
    - isolated ulnar shaft frx can occur in children (night stick mechanism) but w/ an "isolated frx,"
            always consider a pediatric Monteggia's fracture:
           
- Remodeling after Fracture:
    - see acceptable reduction for pediatric both bone forearm frx:
    - correction of ulnar bowing by osteoclasis is not necessary in a child under 4 years old who has
            less than 20 deg of plastic deformation;
    - if bowing is > 20 deg, reduction should be done by first reducing plastically deformed bone
            and then the fracture;
    - immobilization in a well-molded long arm cast is necessary to avoid recurrence of the deformity;
