Purpose The purpose of this study was to review pelvic fractures and concomitant orthopaedic injuries in children who have a patent triradiate cartilage (TRO) compared with children whose triradiate cartilage has closed (TRC). We hypothesise that these injuries will differ, leading to correlated alterations in management. Patients and Methods Using a database, we retrospectively reviewed patients aged below 18 years with pelvic fractures presenting to our Level 1 trauma center. Radiographs and CT scans were reviewed to identify orthopaedic injuries and categorise pelvic injuries using the modified Torode classification between the two groups. Results A total of 178 patients met inclusion criteria (60 TRO and 118 TRC). Mean age ± SD for TRO and TRC groups were 8 ± 4 years and 16 ± 2 years, respectively. TRO patients were more likely to present as a pedestrian struck by a vehicle (odds ratio (OR) 6.0; p < 0.001) and less likely to present after a motor vehicle collision (OR 0.2; p < 0.001). TRO patients were more likely to sustain rami fractures (OR 2.1; p = 0.020) and Torode IIIA injuries (OR 3.6; p < 0.001). They were less likely to sustain acetabular fractures (OR 0.5; p = 0.042), sacral fractures (OR 0.4; p = 0.009), hip dislocations (p = 0.002) and Torode IV injuries (OR 0.4; p = 0.004). TRO patients were less likely to be treated operatively for their pelvic (OR 0.3; p = 0.013) and orthopaedic injuries (OR 0.4; p = 0.006). Conclusion We suggest that patients with open triradiate cartilage are unique. Their pelvic injuries may be treated more conservatively as they have a greater potential for periosteal healing and bone remodelling. Patients with closed triradiate cartilage should be treated similarly to adults, as they share a similar mechanism of injury and need for operative fixation.
