Intersection syndrome scoping review

Background: Intersection syndrome is an overuse injury involving the tendons of the first and second dorsal compartments of the wrist, frequently seen in individuals performing repetitive wrist movements. Despite its clinical significance, the condition remains underrecognized, often resulting in delayed diagnosis and treatment. This scoping review aims to systematically map the existing literature on intersection syndrome, focusing on its clinical presentation, diagnostic modalities, and treatment approaches.

Methods: Following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses extension for Scoping Reviews (PRISMA-ScR) guidelines, a comprehensive search of MEDLINE, Embase, Scopus, Web of Science, and the Cochrane Library was conducted. Studies examining clinical presentation, diagnostic methods, and treatment outcomes for intersection syndrome in human populations were included. Data were extracted and synthesized using a thematic framework, highlighting gaps in the current evidence base.

Results: The review identified key findings related to the variability of symptoms, the utility of diagnostic imaging modalities such as ultrasound and MRI, and the effectiveness of treatment options ranging from conservative management to surgical interventions. Recurrence rates and long-term outcomes were inconsistently reported, emphasizing the need for standardized approaches and robust comparative studies.

Conclusion: This review underscores the critical need for standardized diagnostic criteria and evidencebased management guidelines for intersection syndrome. Further high-quality research is required to address gaps in understanding and improve outcomes for patients with this underrecognized condition.
