Aims. Paediatric pelvic ring fractures are rare but severe injuries, presenting significant treatment challenges. This study aimed to analyze patient characteristics and explore trends in incidence, treatment methods, and mortality associated with these injuries. Methods. This multicentre, retrospective cohort study analyzed paediatric patients (aged ≤ 18 years) with pelvic ring fractures treated between 2001 and 2021 at two level 1 trauma centres. Data on patient demographics, injury characteristics, treatment approaches, and outcomes were collected, and visual trend analysis was conducted to identify patterns. Results. A total of 157 patients with pelvic ring fractures were included. The median age was 15 years (IQR 12 to 17), with 52% (n = 81) being female. Traffic accidents were the leading cause of injury, accounting for 68% of cases (n = 106). Concomitant injuries were observed in 83% of patients (n = 131). The one-year mortality rate was 11.5%, with 76% of deaths occurring within 48 hours of admission, primarily due to traumatic brain injury (53%). Most patients (60%) were treated nonoperatively, while 48% of surgically treated patients underwent internal fixation without prior external fixation. Visual trend analysis revealed an increase in the absolute number of paediatric pelvic ring fractures over time, though no significant shift towards surgical treatment was observed. Among surgically treated patients, there was a trend towards open reduction and internal fixation rather than external fixation as definitive treatment. Nonoperative treatment was more common in children (69%) than in adolescents (55%). For surgical cases, external fixation was preferred in children (44%), while ORIF was more common in adolescents (53%). Conclusion. The incidence of paediatric pelvic ring fractures has increased over time, with a high mortality rate largely attributable to severe neurotrauma. There has been a shift towards surgical treatment without prior external fixation, with differences noted in the treatment approaches between children and adolescents, particularly in surgical fixation methods.

Aims

The aim of this study was to compare the cost-effectiveness of treatment with an osseointegrated percutaneous (OI-) prosthesis and a socket-suspended (S-) prosthesis for patients with a transfemoral amputation.
