Proximal femoral fractures in children: incidence, complications, and functional outcomes-a population-based study from Finland.

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
background and purposePediatric proximal femoral fractures are rare and frequently complicated fractures with avascular necrosis (AVN), nonunion, deformity, leg-length discrepancy (LLD), and premature physeal closure (PPC). Our aim was to describe the incidence, complications and functional outcomes.
methodsIn this register-based study from a 10-year period (2014-2023) we identified 51 non-pathological proximal femoral fractures from the KIDS Fracture Tool database. Statistical yearbooks of Helsinki were utilized to estimate annual incidence. We used interviews and Oxford Hip Scores (OHS) for functional outcome assessment. If any symptom or functional deficit was described, or if Oxford Hip Score (OHS) was < 41, patients were also invited for clinical examination and radiography.
results51 patients with a proximal femoral fracture (31 boys) were identified representing 0.2% (51/21,121) of all child fractures with a population-based annual incidence of 1.7/100,000 children. We interviewed 46/51 of the patients or their guardians via telephone. 6/46 were invited for clinical examination and radiography. Median follow-up of contacted patients was 4 (range 1-9.5) years. Complications occurred in 9/20 patients with collum and trochanteric fractures (pain from osteosynthesis 4, AVN 3, nonunion 1, coxa vara 1, LLD 1, PPC 0) and in 7/31 with subtrochanteric fractures (pain from osteosynthesis 5, misplaced pins 2, angular deformity 1, peri-implant fracture 1). All underwent reoperation. The median OHS was 48 (interquartile range 47-48) at last follow-up. Functional outcomes were impaired in 3 patients. All 3 had AVN.
conclusionThe incidence of non-pathological pediatric proximal femoral fractures is low. Despite frequent complications, impaired functional outcomes concerned only patients with AVN at median 4-year follow-up.
