“…The talocalcaneal (subtalar) joint is composed of three osseous articulating facets which form three talocalcaneal joints: the anterior, middle, and posterior. The anterior and middle talocalcaneal joints are contiguous and are separated from the posterior talocalcaneal joint by the tarsal canal (sinus tarsi) 13 . The tarsal sinus is a funnel shaped anatomic space between the neck of the talus and the anterosuperior surface of the calcaneus 14 .…”

“…15 Laterally, the sinus tarsi is an important sonographic landmark for identifying the bifurcate ligament. The anatomy of the sinus tarsi is variably reported, and it contains adipose tissue, small arteries veins and nerves, a synovial recess, ligaments which stabilise the subtalar joint (cervical ligament and interosseous ligament) and the roots of the inferior extensor retinaculum 13,14,16,17 (Figure 2).…”

Ankle sprains are common. Midfoot ligaments, particularly the dorsal ligaments of the Chopart joint complex, can be injured in combination with other ankle and foot injuries via an ankle sprain, but are clinically difficult to detect. The prevalence of injury to dorsal midfoot ligaments may be underreported as they can be overlooked, underappreciated, and underdiagnosed. Symptoms can include chronic pain, long-term functional limitations, and physical disability due to lack of timely management. Sonographic assessment of the ankle and foot following an ankle sprain should include assessment of the dorsal midfoot ligaments. This paper will provide a description of the sonographic anatomy, appearances, and assessment of the dorsal ligaments of the Chopart joint complex. Early diagnosis of injury can allow for appropriate management and treatment.

“…Both the medial root and the InOL are located near the tarsal canal between the joint capsules of the posterior STj and the TCNj. 34 The InOL has an oblique orientation with its fibers fanning out upward, medially, and anteroposteriorly. Its lateral fibers are longer and have more excursion, whereas the shorter fibers on its inner side have less excursion (isometric).…”

Ligament injuries around the subtalar, talocalcaneonavicular, and calcaneocuboid joints are often underestimated on clinical and imaging findings during investigation of patients with ankle and foot injuries. Because a delayed diagnosis of midtarsal ligament tears may lead to chronic pain and functional disability, an in-depth knowledge of the complex regional anatomy and of the appropriate ultrasound scanning technique is a prerequisite for evaluating these structures and avoiding misdiagnoses. The objective of this article is twofold: to describe the relevant anatomy and biomechanics related to the ligaments that stabilize the subtalar, talocalcaneonavicular, and calcaneocuboid joints, and to illustrate reasoned landmark-based scanning techniques to provide a systematic examination of these ligaments and thus make ultrasound an effective tool for assessment of patients with suspected subtalar or midtarsal sprain.

“…Severe ankle sprains frequently result in chronic ankle instability [5,6]. About 10-25% of these patients also present subtalar joint instability [7,8]. When conservative techniques prove to be ineffective, surgery is indicated to restore overall joint functions [5,6,9] by ligament repair and reconstruction procedures.…”

Effect of Ligament Mapping from Different Magnetic Resonance Image Quality on Joint Stability in a Personalized Dynamic Model of the Human Ankle Complex

Background. Mechanical models of the human ankle complex are used to study the stabilizing role of ligaments. Identification of ligament function may be improved via image-based personalized approach. The aim of this study is to compare the effect of the ligament origin and insertion site definitions obtained with different magnetic resonance imaging (MRI) modalities on the mechanical behaviour of a dynamic model of the ankle complex. Methods. MRI scans, both via 1.5 T and 3.0 T, were performed on a lower-limb specimen, free from anatomical defects, to obtain morphological information on ligament-to-bone attachment sites. This specimen was used previously to develop the dynamic model. A third ligament attachment site mapping scheme was based on anatomical dissection of the scanned specimen. Following morphological comparison of the ligament attachment sites, their effect on the mechanical behaviour of the ankle complex, expressed by three-dimensional load–displacement properties, was assessed through the model. Results. Large differences were observed in the subtalar ligament attachment sites between those obtained through the two MRI scanning modalities. The 3.0 T MRI mapping was more consistent with dissection than the 1.5 T MRI. Load–displacement curves showed similar mechanical behaviours between the three mappings in the frontal plane, but those obtained from the 3.0 T MRI mapping were closer to those obtained from dissection. Conclusions. The state-of-the-art 3.0 T MRI image analysis resulted in more realistic mapping of ligament fibre origin and insertion site definitions; corresponding load–displacement predictions from a subject-specific model of the ankle complex showed a mechanical behaviour more similar to that using direct ligament attachment observations.
