This page refers to sinus tarsi syndrome (STS), a syndrome characterized by lateral hindfoot pain at the level of the Sinus Tarsi History First described by Denis O'Connor in 1958 Epidemiology Most patients present in the 3rd, 4th decade of life (need citation) Pathophysiology General CONCLUSION: Cadaveric study results indicate that initial and reconstructed MR arthrograms along and perpendicular to the ligament axes are potentially useful for further evaluation of individual tarsal sinus structures. Etiologies of pain within the sinus tarsi region are not well understood, but typically occur after trauma that leads to tearing of the CL and ITCL. Yamaguchi R, Nimura A, Amaha K, Yamaguchi K, Segawa Y, Okawa A, Akita K. Foot Ankle Int. PubMed. 2022 Sep;25(3):777-781. doi: 10.1007/s40477-021-00571-1.

This approach is subfibular and slightly anterior and keeps the peroneal tendons inferiorly. The inferior extensor retinaculum arises from the sinus tarsi in the form of three roots (medial, intermediate and lateral) which are collectively termed the frondiform ligament which is readily identified on ultrasound and can be used as a reference point to aid the safe delivery of injectate material into the sini. Cadaver studies have shown that there are two distinct ligaments in the tarsal sinus: ITCL and anterior capsular ligament (ACL) [ 7, 8 ]. When acute, most of these tears demonstrate fluid violating the margins. 24, No. 3, The Journal of Foot and Ankle Surgery, Vol. 1- stiffn Developed by renowned radiologists in each specialty, STATdx provides comprehensive decision support you can rely on - Sinus Tarsi Syndrome.

Tarsal sinus ligaments were evaluated further on initial and reconstructed MR arthrograms along and perpendicular to their axes. Sinus Tarsi Syndrome usually presents with lateralfoot pain and tenderness. To evaluate the tarsal sinus by using different imaging techniques and specialized planes. A problem-based approach in musculoskeletal ultrasonography: heel pain in adults. Sinus tarsi syndrome is difficult to diagnose clinically and shows few radiographic findings. Sinus Tarsi is a space on the lateral aspect of the foot between neck of the talus and superior aspect of the calcaneum. MR image findings. Diagnosis. It is usually due to instability of the joint connecting the foot to the heel (subtalar). 06, Radiologic Clinics of North America, Vol. There are three ligaments on the lateral side: anterior talofibular ligament (ATFL) calcaneofibular ligament (CFL) posterior talofibular ligament (PTFL). The sinus tarsi ligaments are often oblique to the imaging planes obtained on MR imaging, and therefore will be visualized in cross section on contiguous slices. A preoperative Magnetic Resonance Imaging (MRI) scan was performed to determine the causing substrate for complaints as well as the location of the affected tissue (s). Conclusion: a. Ankle: Passive movement must be assessed with forefoot in supination and inversion of heel (to exclude dorsiflexion at chopart's joint and midtarsal joint and to lock subtalar joint).

Ganglia were associated with the interosseus ligament in 81% (21/26), the cervical ligament in 31% (8/26) and the retinacula in 46% (12/26) of patients, thus in 27% (7/26) of patients, ganglia were found at multiple locations within the sinus tarsi ( Fig. 3, Orthopaedics & Traumatology: Surgery & Research, Vol. 12, BioMedical Engineering OnLine, Vol. The sinus tarsi is located between the ankle bone and the heel bone, and is filled with fat, ligaments, muscles, as well as nerve . 2018 Oct;26(10):3135-3139. doi: 10.1007/s00167-017-4813-2. This small tunnel contains nerves, sinus tarsi ligaments, and blood vessels that can be damaged and cause pain. In pathomorphological terms this is due neither to a ligament rupture nor to an osteochondral lesion. Two of the ligaments in the sinus tarsi assist the posterior tibial tendon and spring ligament in maintaining the longitudinal arch of the foot.

Bookmarks. The results of this study show that the CL is the primary ligament in the tarsal sinus and that the ITCL is a thin single band rather than a strong bilaminar ligament located inside the tarsal canal. FOIA The https:// ensures that you are connecting to the 11, Zeitschrift fr Orthopdie und Unfallchirurgie, Vol. The sinus tarsi and tarsal canal mainly contain five ligaments, namely - the cervical ligament, the three roots of the inferior extensor retinaculum (medial, intermediate and lateral roots) and the interosseous talocalcaneal ligament. 2, 2022 Radiological Society of North America, Tarsal Sinus: Arthrographic, MR Imaging, MR Arthrographic, and Pathologic Findings in Cadavers and Retrospective Study Data in Patients with Sinus Tarsi Syndrome, https://doi.org/10.1148/radiology.219.3.r01jn31802, Adult Acquired Flatfoot Deformity: Anatomy, Biomechanics, Staging, and Imaging Findings.
