Prevalence of hip dislocation and subluxation among children with cerebral palsy: an institution-based cross-sectional study from a Sub-Saharan country.
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
backgroundHip dislocation in children with cerebral palsy (CP) presents significant challenges, including pain, and severe contractures, which impair positioning, sitting, standing, and walking. This study investigated the prevalence and factors associated with hip displacement in a cohort of children with CP in a resource-limited setting lacking a dedicated hip surveillance program.
methodsA cross-sectional study was conducted from August 1, 2023, to January 30, 2024, at Tikur Anbesa Hospital, Ethiopia's largest tertiary hospital. The study included 141 children with CP who met the inclusion criteria and underwent hip radiography. The hip migration percentage was assessed, with hip subluxation defined as a migration percentage between 30% and 80% and hip dislocation defined as a percentage greater than 80%. The migration percentages were analyzed in relation to sociodemographic and clinical data via statistical tests.
resultsThe study cohort predominantly consisted of children with spastic tetraplegic CP (56.7%), and 52.6% had GMFCS levels IV and V. A high comorbidity rate was observed, with 98% of the children having additional conditions, the most common being epilepsy (59%). The prevalence of hip displacement was 28%, with 88% of these cases classified as hip subluxation and nearly 11% as dislocation. Displacement was more common in the left hip (56.4%) than in the right hip or both hips. Osteopenia was present in 3.5% of the children. Factors associated with hip displacement included home rehabilitation, frequency of carrying by caregivers, GMFCS levels, and being aged 5-10 years.
conclusionsThis study highlights the significant prevalence of hip displacement among children with CP in a resource-limited setting, despite being managed at a tertiary hospital. The findings underscore the need for the implementation of hip surveillance programs and timely interventions to prevent or mitigate hip displacement, thereby enhancing the quality of life and functional outcomes of these children.
