Pediatric Distal Radius Fracture


- Discussion:
    - children's frx are rarely intra-articular; 
    - common types:
          - physeal frx 
          - torus fracture 
          - green stick frx 
          - both bone forearm frx   
          - galeazzi's frx
          - distal radius fracture:
                - w/ bayonete opposition, the child should receive general anesthesia with closed reduction and pin fixation;
                        - if closed reduction is not possible, then insert a 1 mm K wire percutaneously into fracture site and use it to "lever" the fracture into a reduced position;
                - references:
                        - Completely displaced distal radius fractures with intact ulnas in children.   
                        - Management of completely displaced metaphyseal fractures of the distal radius in children. A prospective, randomised controlled trial. 
                 

    - associated injuries:
          - condylar and supracondylar frx;


 - Anesthesia:
     - note that in children, the term "IV sedation" should be changed to "IV anesthesia," since any amount of IV sedatives are potentially dangerous;
     - determine when the child last ate;
     - realize that a painful fracture can cause a gastric ileus, and therefore, waiting 8 hours before administering IV anesthetics does not at all guarentee that the child's stomach will be empty;

 - Reduction:
    - distal both bones forearm frx:
            - pure traction may actually make it more difficult to oppose the frx ends due to tightening of the overlying periosteum (like a chinese finger trap);
            - distal radius is hyperextended and the distal fragment is pushed distally until the dorsal cortex is out to length;
                   - distal fragment is then "hinged over" the frx site;
            - if closed reduction is still not possible, then insert a 1 mm K wire percutaneously into fracture site and use it "lever" the fracture into a reduced position;
    - reference:

      - case example:
             
             - 2 yr old male who sustained a simple distal radial torus frx;
             - he was treated w/ a sugar tong splint, was sent home, and cried all night;
             - several days later, it was apparent that he sustained a 3rd degree burn to the forearm, as well as a Volkman's ischemic contracture;
