Insights
Skeletally mature children with pelvic injuries experience more complex fractures and associated injuries, requiring more operative treatment than skeletally immature children. This study highlights differences in pediatric pelvic trauma based on skeletal maturity.
Area of Science:
- Orthopaedic Surgery
- Pediatric Trauma
- Radiology
Background:
- Pediatric pelvic injuries are uncommon and present unique patterns due to immature anatomy.
- Understanding skeletal maturity's impact is crucial for accurate diagnosis and treatment.
- Previous research has not fully elucidated these differences.
Purpose of the Study:
- To analyze the influence of skeletal maturity on pediatric pelvic injury patterns.
- To investigate associated injuries in relation to skeletal maturity.
- To determine treatment variations based on skeletal maturity.
Main Methods:
- Retrospective analysis of 90 children with pelvic injuries (March 2002-June 2011).
- Skeletal maturity assessed by triradiate cartilage closure.
- Classification using OTA/AO and Young and Burgess systems; Injury Severity Score (ISS) recorded.
Main Results:
- Skeletally mature children sustained more complex and unstable pelvic injuries (p=0.014).
- Higher rates of operative intervention (p=0.009) and higher ISS (p=0.013) were observed in mature children.
- Mature children had significantly more associated injuries, including urinary tract injuries (p=0.049).
Conclusions:
- Skeletal maturity significantly influences pediatric pelvic injury patterns and severity.
- Mature children require more complex management, including operative treatment.
- Higher incidence of associated injuries in skeletally mature pediatric patients necessitates comprehensive evaluation.
Introduction:
Pediatric pelvic injuries are rare. Due to anatomic differences of the immature pelvis, different injury patterns may occur as compared to adults. The purpose was to analyze the effect of skeletal maturity on pediatric pelvic injury pattern, associated injuries, and treatment intervention.
Patients And Methods:
Ninety children with a pelvic injury receiving treatment at a private orthopaedic practice in association with a Level One Teaching Trauma Center, between March 2002 and June 2011, were retrospectively analyzed. Skeletal maturity was determined as closed triradiate cartilage. Forty-one (46%) were skeletally immature and 49 (54%) were skeletally mature. Mean age was 11.5 years (2-16). Fractures were 23 A2, 1 A3, 4 B1, 44 B2, 16 B3, and 2 C2 according to OTA/AO classification. OTA B and C fractures were 26 LC1 (lateral-compression), 20 LC2, 10 LC3, 4 APC1 (anterior-posterior-compression), 5 APC2, and 1 VS (vertical-shear) injury according to Young and Burgess. Treatment of the pelvic injury was operative in 28 (31%) and non-operative in 62 (69%) of children. Mechanism of injury, Injury Severity Score (ISS), deaths, and associated injuries were recorded.
Results:
More complex and unstable injuries occurred in skeletally mature vs. immature children (p = 0.014). Skeletally mature children had a significantly higher rate of operative intervention (p = 0.009). The ISS in skeletally mature children was higher 25 (1-66) than in skeletally immature children 17 (4-43) (p = 0.013). 84% (41) skeletally mature and 78% (32) skeletally immature children sustained associated injuries. Twenty-two% (11) of all skeletally mature children sustained urinary tract injuries, but only 7% (3) of all skeletally immature children (p = 0.049).
Discussion:
Skeletally mature children are more likely to sustain more complex injury patterns with a higher rate of operative treatment, to have a higher rate of associated injuries, and to have a higher ISS than immature patients.
Level Of Evidence:
Retrospective comparative study, Level III.
