The African Child Provides Us with a New Mechanism for “Fall Astride Injury”: A Narrative Review

Abstract

Purpose: Fall-astride injuries are well recognized as a cause of anterior urethral trauma, typically following bicycle accidents, fence straddles, or bathtub slips. We aimed to describe a novel, culturally specific mechanism of pediatric fall-astride injury observed in a rural African setting (“the running stick mechanism”) and contextualize it within existing literature. We use the term “running‑stick mechanism” to describe an observed childhood play in Southeastern Ghana in which a child clasps a rigid stick between the thighs while running forward, positioning the perineum against a narrow, firm object. A trip or sudden deceleration can reproduce the classical fall‑astride impact on the bulbar urethra. Materials and Methods: Through non-participant observation in serendipity, and digital reconstruction, we documented children simulating bicycle riding by clasping a rigid stick between their thighs while running (“running-stick mechanism”). A systematic literature search was then conducted across 11 databases (PubMed, PMC, ScienceDirect, BMC Surgery, Wiley Online Library, AJOL, etc.) using the terms fall astride injury mechanisms and straddle trauma . Findings were synthesized narratively, with illustrative diagrams created for health education. Results: Despite identifying 22 relevant sources on straddle injuries, no prior report described the running-stick mechanism. Biomechanical analysis confirmed parallels with classic fall-astride trauma, particularly risk of bulbar urethral injury, hematoma, and potential stricture formation. Immediate caregiver education discouraged repetition of the behavior during 16-week follow-up. Visual illustrations were produced to support clinical and public health awareness. Conclusions: The “running-stick” play represents a previously undocumented but biomechanically valid mechanism of pediatric fall-astride injury. Its identification highlights the need for culturally informed surveillance, early caregiver education, and preventive strategies in low-resource settings. Recognition of such mechanisms may improve diagnostic suspicion and reduce the long-term burden of pediatric urethral trauma.
