S.H. Type I





- Discussion:
      - affects young childhood;
      - growth plate is thick;
      - large hypertrophying chondrocytes
      - weak zone provisional calcification
      - mechanism:
            - pure shear;
            - frx lines follow growth plate, separating epiphysis from metaphysis;
      - unless the periosteum is torn, displacement cannot occur;
      - w/o displacement radiographs appear normal;
      - healing is rapid, usually within 2-3 weeks;
      - complications are rare;
