Sinus tarsi syndrome Radiology Case

Sinus tarsi syndrome is the clinical syndrome of pain and tenderness of the lateral side of the hindfoot, between the ankle and the heel. Imaging often demonstrates the ligaments and soft tissues in the sinus tarsi are injured. Epidemiology The tarsal sinus (or sinus tarsi) is a cylindrical cavity located between the talus and calcaneus on the lateral aspect of the foot. MRI is the investigation of choice for evaluating the tarsal sinus structures. Gross anatomy The tarsal sinus is situated on the lateral side of the foot; distal and slightly anterior to the lateral malleolus.

The sinus tarsi, also known as the tarsal sinus, is defined as the anatomical space between the neck of the talus and anterosuperior calcaneus. It is roughly cone-shaped, with the wider portion directed anteriorly and laterally. The sinus tarsi is a funnel-shaped region at the junction of mid-foot and hind-foot which contains fat, vessels, nerves and ligaments. The ligaments help stabilise the subtalar joint and maintain the longitudinal arch of the foot. The nerve endings contain proprioceptive fibres indicating a role for the sinus tarsi in movement of the foot. Sinus tarsi syndrome (STS) is a clinical entity characterized by persistent anterolateral ankle pain secondary to traumatic injuries to the ankle. Historically, the etiology of this condition has not been well understood. Abnormalities of the tarsal sinus and canal were seen on MR images in 33 cases (26.8%), were highly associated with tears of the lateral collateral ligament, and could be categorized according to the pathologic findings in patients with sinus tarsi syndrome: (a) diffuse infiltration with low T1- and T2-weighted signal intensity (n = 17) consiste.

Tarsal coalition is a congenital bridging of two or more tarsal bones. The bridging may be fibrous (syndesmosis), cartilaginous (synchondrosis), or osseous (synostosis). Abstract PURPOSE: To evaluate the tarsal sinus by using different imaging techniques and specialized planes. MATERIALS AND METHODS: Magnetic resonance (MR) imaging of the tarsal sinus was performed in 10 cadavers. Conventional arthrography of the anterior and posterior subtalar joints was then performed. 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. Sinus tarsi syndrome is a clinical entity characterised by lateral hind-foot pain with worsening on palpation and weight-bearing, and perceived instability. It is associated with both traumatic and non-traumatic causes. Magnetic resonance imaging is the imaging modality of choice for assessment of the sinus tarsi and sinus tarsi syndrome.

The clinical syndrome can be attributed to trauma in about 70% and to chronic inflammation or deformity of the foot in the 1. Introduction. The sinus tarsi is a cylindrical canal located in the hindfoot, bordered by the neck of the talus and anterosuperior calcaneus. The anatomy of this region is complex, with five ligamentous structures lying within it, including the intermediate, medial and lateral roots of the inferior extensor retinaculum, the cervical ligament (CL) and the interosseous talocalcaneal ligament.
