Pediatric Acetabular Fractures


- See: Pediatric Pelvic Fractures

- Discussion:
    - disruption of acetabular triradiate cartilage in patient > age 12 will result in minimal subsequent growth disturbance;
    - in younger pts acetabular growth abnormality is frequent complication;
          - may result in shallow acetabulum & progressive subluxation of hip;
          - in younger pts, acetabular reconstruction is best accomplished w/ Chiari osteotomy;
    - in the report by Dora C, et al (2000), the authors followed 10 patients with post traumatic acetabular dysplasia;
          - all ten patients demonstrated marked retroversion averaging 27 deg (where as the contralateral acetabuli showed 23 deg of anteversion);
          - average center edge angle was 9.5 deg;
          - hip joint is typically lateralized and caudalized;
          - there is a significant posterolateral deficiency;

- Hip Dislocation:
    - hips may dislocate and subsequently will reduce spontaneously;
    - widening of the medial joint space may indicate cartilagenous entrapment
