Analysis of risk factors affecting the prognosis of external fixation in the treatment of unstable pelvic fractures in children: a retrospective study of 96 patients.
Article in BMC pediatrics, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundTo investigate the efficacy of external fixation in treating unstable pelvic fractures in children and identify risk factors for poor prognosis.
methodsA retrospective study was conducted on children with unstable pelvic fractures treated surgically at our hospital from January 2006 to June 2022. All patients received external fixation, and those with vertical instability underwent postoperative limb traction. Data collected included gender, age, injury mechanism, associated injuries, imaging results, operation time, blood loss, pelvic reduction status, complications, and functional recovery. Variables were analyzed using multiple linear regression to explore risk factors for poor prognosis.
resultsThe study included 96 patients (62 males, 34 females) with an average age of 95.7 ± 50.3 months. Injury mechanisms were mainly traffic accidents (82.3%) and falls (14.6%). There were 47 cases of Tile B fractures and 49 cases of Tile C fractures. Surgeries were successful with an average operation time of 55.6 ± 27.3 min and blood loss of 6.3 ± 4.7 ml. Immediate postoperative Matta reduction quality was excellent in 91.7% of cases. Postoperatively, 46 patients underwent limb traction for an average of 9.3 ± 1.4 weeks. The average follow-up duration was 29.3 ± 11.7 months, and fracture healing time was 8.6 ± 1.1 weeks. At the final follow-up, 83.3% had excellent or good Cole pelvic function scores. WeeFIM scores indicated complete independence in 71 cases, conditional independence in 13, and conditional dependence in 12. Multiple linear regression identified age, Tile classification, and immediate postoperative displacement as independent predictors of prognosis. Patients aged ≥ 13 years, with Tile C fractures, and immediate postoperative displacement ≥ 8 mm had lower Cole scores.
conclusionsExternal fixation combined with lower limb traction effectively treats unstable pelvic fractures in children, with most patients having a favorable prognosis. Assessment of age, fracture type, and reduction quality is essential. Enhanced postoperative follow-up and functional exercises are recommended for older children, those with Tile C fractures, and those with significant immediate postoperative displacement. Clinicians should consider these factors to improve outcomes. LEVEL OF EVIDENCE: III.
