“…Traction and eversion is used to reduce a medial subtalar dislocation, and, on the other hand, traction with lateral rotation of foot is needed to reduce swivel. Possible causes of obstruction to reduction can be advocated to be interposition of the tibialis posterior tendon or impacted fractures of the talus or navicular [ 9 , 10 ].…”

Subtalar or peritalar dislocation is the loss of contact between the articular surface of the talus distally and the calcaneum and navicular. In this paper, a case of open medial type of subtalar dislocation associated with fractured posterior facet of the talus in a 27-year-old man with a history of road traffic accident was reported. Immediate wound irrigation and open reduction under general anesthesia at the emergency room operation theater was successful followed by cast immobilization. At one-year follow-up, the patient was walking and carrying out his daily activities with mild restriction of inversion and eversion movements. Extensive wound debridement followed by immediate reduction and, when required, stabilization are the principal features of management. Open subtalar dislocation is an extremely rare injury and often poses a treatment dilemma. Early debridement and open reduction of the dislocation like in our case can give good functional outcome for an open medial subtalar dislocation at one-year follow-up. Temporary stabilization of dislocation in the form of Kirschner wires maybe needed in some cases only.

“… 4 The most reported one is a plantar flexion/compressive injury. 4 5 9 10 The position of the foot and the direction of the force at injury will determine the direction of the dislocation. Main and Jowett 11 had considered that longitudinal forces transmitted along the metatarsal rays would compress the navicular, produce dorsal dislocation; this theory was based on radiographic appearances.…”

Isolated dislocation of the tarsal naviculum is an unusual injury, scarcely reported in the literature. The naviculum is surrounded by the rigid bony and ligamentous support hence fracture dislocation is more common than isolated dislocation. The mechanism and treatment options remain unclear. In this case report, we describe a 31 year old man who sustained an isolated dorsal dislocation of the left tarsal naviculum, without fracture, when he was involved in a motor vehicle collision. The reported mechanism of the dislocation is a hyper plantar flexion force applied to the midfoot, resulting in a transient disruption of the ligamentous support of the naviculum bone, with dorsal displacement of the bone. The patient was treated with open reduction and Krischner-wire fixation of the navicular after the failure of closed reduction. The wires were removed after 6 weeks postoperatively. Physiotherapy for stiffness and midfoot pain was recommended for 2 months. At 6 months postoperatively, limping, midfoot pain and weakness were reported, no X-ray abnormalities were found. The patient returned to his obvious activities with a normal range of motion.

“…1 , 2 However, pure dislocation of the TNJ without an associated fracture of either the TNJ or calcaneocuboid joint is extremely uncommon; other reports have tended to describe coexisting injuries. 3 – 7 We herein present a case of a pure isolated medial swivel dislocation of the TNJ that was sustained following low-energy trauma without an associated fracture.…”

Pure isolated medial talonavicular joint dislocation following low-energy trauma: a case report

et al. 2021

Midtarsal dislocations are relatively rare injuries secondary to high-energy trauma and are typically accompanied by disruption of ligamentous structures and fractures of the midfoot. We herein present a case of a pure isolated medial swivel dislocation of the talonavicular joint (TNJ) that was sustained following low-energy trauma without an associated fracture. A 78-year-old woman visited our emergency department with severe pain in the midfoot area of the right foot without neurovascular deficits. She had sustained this injury after severe ankle inversion while going downstairs. Plain radiographs of the right foot showed that the navicular was dislocated medially on the talus; no other malalignments were present. Three-dimensional computed tomography revealed dislocation of the TNJ, but no other tarsal or midtarsal bone fractures or dislocations. A medial dorsal incision was made to expose the TNJ. The dorsal talonavicular ligament was ruptured and interposed between the navicular and talus. The ligament was removed and the TNJ was reduced. The clinical outcome at the 1-year follow-up was satisfactory with no limitations in daily activities. In summary, we have reported an extremely rare case of a pure isolated medial TNJ dislocation in which the interposed dorsal talonavicular ligament served as an obstacle to reduction.
