Current concepts in sinus tarsi syndrome: A scoping review

Abstract

Introduction: Sinus tarsi syndrome is a relatively unknown condition presenting with pain and a feeling of instability. We aim to summarise evidence on the aetiology, diagnosis and treatment of the condition, whilst answering the question of whether the term should be used.

Methods: Scoping review following the methodological frameworks of Arksey and O'Malley, Levac and Peters. The review protocol is registered with the Open Science Framework: (https://osf.io/wj6ct/?view_only=59445d344ec34b6fab640d2fa7a83943).

Results: In total, 605 studies were identified, 31 of which met selection criteria. Sinus tarsi syndrome is used to describe a range of distinct underlying pathologies. MRI and arthrography show non-specific abnormalities in patients and identifying underlying pathologies is challenging.

Discussion: The distinct range of underlying pathologies makes identifying specific imaging abnormalities and optimal treatments difficult. Further research in determining optimal treatments for specific pathologies and investigating the efficacy of conservative treatment must be conducted, before we can justify a more specific diagnosis.
