Describing Frequencies of Lower-Limb Apophyseal Injuries in Children and Adolescents: A Systematic Review.

Supplemental Digital Content is Available in the Text. Objective: To describe the frequency with which children are affected by lower-limb apophyseal injuries, and subgroups at greater risk. Design: Systematic review. Setting: N/A. Participants: N/A. Interventions: N/A. Main Outcome Measures: Systematic review of Medline OVID, PsycINFO, Cinahl, and PubMed from inception until February 21st, 2020. Articles reporting prevalence and/or incidence of an apophyseal injury (eg, calcaneal apophysitis) or its eponym (Severs or Sever disease). Per person data relating to the incidence or prevalence. Subgroup comparisons were made between sex groups and between activity participant groups. Results: There was wide variation in measurement approaches and follow-up timeframes with the majority of studies reporting on traction apophysitis of the tibial tubercle (Osgood–Schlatter disease). This condition had a point prevalence of 10% in the general population of children between the ages of 12 and 15 years, whereas the lifetime incidence has been reported as 13%. Point prevalence was higher among those who participated in sport compared with those who did not {relative risk [95% confidence interval (CI): 1.98 (1.31-2.99)]}, whereas lifetime incidence was higher among those who participated in sport at the age of 13 years compared with those who did not [relative risk (95% CI): 4.63 (2.31-9.26)]. Other apophyseal injuries did not report enough data to permit comparisons. Conclusion: Sports participation is likely to substantially increase the frequency of traction apophysitis of the tibial tubercle. Further research is required with standardized approaches to compare frequencies between different apophyseal injuries and subgroups of interest. [ABSTRACT FROM AUTHOR]
