“…The posterior facet of the calcaneus is the largest and articulates with the inferior surface of the talar body. The posterior facet is separated from the anterior and middle facet by the calcaneal sulcus in the calcaneus, which forms with the equivalent sulcus tali in the talus the sinus tarsi . Many tendons lie close together to the STJ and inflammation of tendon sheaths may mimic STJ involvement.…”

Objective. To investigate the frequency of ultrasound (US)-detectable involvement of the subtalar joint (STJ), to compare clinical versus US assessment of the STJ, and to compare different scanning approaches to the STJ in juvenile idiopathic arthritis (JIA). Methods. Clinical and US assessments were performed independently in 50 ankles with clinically active JIA. US abnormalities of the STJ were investigated using a lateral, medial, and posterior scanning approach and scored semiquantitatively. Agreement was tested using kappa statistics. A control group of 10 healthy subjects was examined.Results. Clinical and US evaluations detected synovitis in 24 of 50 (48.0%) and 27 of 50 (54.0%) of STJs, respectively. US detected synovitis in 10 of 26 STJs (38.5%) recorded as normal on clinical evaluation, but was negative in 7 of 24 STJs (29.2%) diagnosed as having involvement on clinical examination. Agreement between clinical and US assessments was fair (k 5 0.32). US abnormalities were more frequently detectable using the lateral scanning approach. All patients with US abnormalities in the medial and/or posterior side of the STJ had also US abnormalities on the lateral scanning approach, but the reverse was not true. Intra-and interobserver agreements for the lateral scanning approach were satisfactory for both detecting involvement and scoring US abnormalities. None of the 17 STJs of healthy controls showed US abnormalities. Conclusion. US may increase the precision of the evaluation of the STJ in JIA. The observed high frequency of STJ involvement on US suggests to include this joint in US scanning protocols devised for children with JIA. Synovitis is more frequently detected using the lateral scanning approach.

“…Of note, prior research has demonstrated that measurements of DRRs are sufficiently equivalent to measurements of conventional radiographs . The eight DRR views of the foot and ankle included the: (i) the antero‐posterior (AP) view; (ii) the mortise view (20 degrees internal rotation out of the AP view); and (iii) the subtalar joint view (modified Harries Beth view); (iv) the 40/30 degrees Broden view (40 degrees internal rotation and 30 degrees upward tilt of the foot); and multiple (5–8) Broden views (45/10 to 45/40 degrees) . These eight views were selected as they are frequently used to image the ankle (AP and mortise view) and subtalar joint (subtalar view, Broden views) in the coronal plane .…”

“…18,19 These eight views were selected as they are frequently used to image the ankle (AP and mortise view) and subtalar joint (subtalar view, Broden views) in the coronal plane. 15 The calcaneal and talar side of the subtalar joint were visualized using DRRs, but beads were only placed on the posterior facet of the calcaneus. On each DRR, the morphology of the calcaneal posterior facet was rated as either convex, flat, or concave.…”

Evaluation of the subtalar joint using conventional radiographs is difficult. The purpose of this study was to assess how the posterior facet of the subtalar joint is projected on eight standard radiographic views of the foot and ankle. Weightbearing computed tomography (CT) scans of 27 volunteers without ankle pathology were performed. Eight standard views of the foot and ankle (antero‐posterior [AP] view, mortise view, subtalar view, four different Broden views) were reconstructed using digitally reconstructed radiographs (DRRs). The appearance of the posterior facet of the subtalar joint was assessed for each view. In addition, the position of the joint line was projected onto three‐dimensional (3‐D) models of the calcaneus. We found (i) on the AP view of the ankle joint, the posterior part of the posterior facet is visualized and appears convex (calcaneal side); (ii) on the mortise view of the ankle joint, a slightly more anterior part (compared to the AP view) is visualized and appears either convex or flat; (iii) on the subtalar view, the anterior part of the posterior facet is visualized and appears either convex, flat or concave; and (iv) using the Broden views, the posterior and anterior part of the posterior facet can be visualized. This study clarifies which parts of the posterior facet of the subtalar joint are visualized on eight standard views of the foot and ankle. © 2019 Orthopaedic Research Society.

Subtalar joint anatomy is complex and can vary significantly between individuals.Movement is affected by several adjacent joints, ligaments and periarticular tendons.The subtalar joint has gained interest from foot and ankle surgeons in recent years, but its importance in hindfoot disorders is still under debate.The purpose of this article is to give a general overview of the anatomy, biomechanics and radiographic assessment of the subtalar joint.The influence of the subtalar joint on the evolution of ankle joint osteoarthritis is additionally discussed.Cite this article: EFORT Open Rev 2017;2:309-316.
