Pediatric pelvic ring injuries often result in lasting deformity, especially with complex, unstable fractures. Operative treatment for these injuries is linked to increased residual deformity and pain.
Area of Science:
- Orthopedic Surgery
- Pediatric Traumatology
- Radiographic Imaging
Background:
- Pediatric pelvic ring injuries are rare, occurring in less than 0.2% of pediatric fractures.
- Historically treated conservatively, a shift towards operative management is observed due to malunion and long-term morbidity risks.
- This study evaluates outcomes of complex pediatric pelvic ring injuries.
Purpose of the Study:
- To determine clinical and radiographic outcomes in children with pelvic ring injuries.
- To compare outcomes between operatively treated unstable injuries and non-operatively treated stable injuries.
- To identify factors associated with residual deformity and pain.
Main Methods:
- Level IV retrospective analysis of 33 pediatric patients (mean age 12.6 years) with pelvic ring injuries.
- Injuries classified using OTA/AO system (2 A2, 3 B1, 16 B2, 10 B3, 2 C2).
- Group 1: 16 unstable, operatively treated; Group 2: 17 stable, non-operatively treated. Evaluated radiographic deformity, leg length discrepancy, low back, and SI joint pain.
Main Results:
- Operatively treated unstable injuries (Group 1) showed higher rates of permanent ischial height difference (>5mm) and pelvic asymmetry compared to non-operatively treated (Group 2).
- Posterior sacral displacement of 5-10mm correlated with significantly more pain.
- 39% of patients experienced residual low back/SI joint pain, with higher rates in Group 1.
Conclusions:
- Radiographic deformity in pediatric pelvic ring injuries persists and does not remodel.
- Complex, unstable pelvic ring injuries are associated with more deformity and pain.
- Operative intervention for complex displaced injuries may lead to higher rates of residual deformity and pain.

Fractures: Bone Repair
Minor fractures with no bone displacement are treated by immobilizing the fractured bone using a cast or splint. However, in the case of fractures with displaced bones, the broken bones are repositioned before immobilization to ensure successful healing without deformation and loss of function. The realignment of fractured bone ends is performed through a process called reduction. If the...
