Background:
Existing classification systems may not adequately describe the injury patterns seen pelvic ring and acetabular fractures in the skeletally immature population. Pediatric patients, once stabilized, are often transferred for these injuries. We evaluated which commonly used systems correlate with clinical management in pediatric patients, including transfer patterns based on injury severity.
Methods:
A retrospective review of patients aged 1 to 15 treated for traumatic pelvic or acetabular fractures over a 10-year period at an academic level I Pediatric Trauma Center reviewed demographic, radiographic, and clinical data.
Results:
A total of 188 pediatric patients (average age 10.1 y) were included. Increasing injury severity based on classification Arbeitsgemeinschaft für Osteosynthesefragen/Orthopaedic Trauma Association (AO/OTA P<0.001; Young and Burgess P<0.001; Torode/Zieg P<0.001), increasing Injury Severity Score (P=0.0017), and decreasing hemoglobin levels (P=0.0144) were significantly associated with operative management. Injury characteristics did not differ between patients who were transferred versus patients who were brought in directly from the field. Air transport was significantly associated with surgical treatment, pediatric intensive care unit admission, polytrauma, and Torode/Zieg classification (P=0.036, <0.0001, 0.0297, 0.0003, respectively).
Conclusions:
Although not fully descriptive of skeletally immature fracture patterns, the AO/OTA and Young and Burgess classification systems adequately assess the severity of pelvic rings and injuries in pediatric patients and predict management patterns. The Torode and Zieg classification also predicts management. In a large cohort, air transport was significantly associated with surgical treatment, need for pediatric intensive care unit stay, the presence of an additional injury, and instability in the Torode and Zieg classification. These findings suggest that air transfers are being utilized to expedite advanced-level care in more severe injuries. Further studies with long-term follow-up are required to assess the clinical outcomes of both nonoperatively and operatively treated pediatric pelvic fractures and to guide both triage and treatment decisions for these rare but severe injuries.
