Widened ankle mortise symptoms 13-1 to 13-3)—The normal ankle is a three-bone articulation stabilized on both sides by ligamentous structures. Assess for traumatic malalignment and ankle syndesmotic injury: Examine the medial and lateral ankle mortise on dedicated mortise view for symmetry. They are estimated to comprise ~10% (range 1-20%) of ankle injuries. The anatomy involved and the mechanism of injury are extremely relevant for the understanding and treatment of this type of injury. Syndesmotic injuries do occur in children, especially those who participate in sports that involve cutting and pivoting (football, soccer) or sports with rigid immobilization of the ankle (skiing, hockey). The most frequent malunions of the fibula are shortening and malrotation resulting in widening of the ankle mortise and talar instability, which may lead to posttraumatic osteoarthritis [7–10]. Data were collected by 1 author (M. INTRODUCTION. If no fracture exists, a stress-view XR of the ankle mortise should be obtained to identify possible widening Abduction and external rotation anterior-posterior stress image of left ankle demonstrating unstable syndesmosis and wide medial clear space. Consequently, the talus will lose its stability in the coronal plane, which may result in tilting or translational movements (Figs. Based on those findings, stabilization is the recommended approach. Jun 2, 2024 · Symptoms include severe pain, swelling, and an inability to bear weight on the affected foot. Most ankle sprains can be treated successfully with an aggressive nonsurgical care program that is tailored to the individual athlete. Malleolar fractures have been the subject of numerous articles regarding mechanism of injury, classification, and treatment. 37 Mar 28, 2018 · The ankle joint range of motion was measured at 5° of dorsiflexion and 25° of plantarflexion. 2 A: In a mortise view, Shenton line of the ankle is the subchondral bone contour of the tibia plafond and fibula, which should be a curved, unbroken line (dotted line) in the intact ankle. Simple radiographs demonstrated an increasingly widened ankle mortise and aggravated disruption of the distal tibiofibular joint. 12 Because of the high likelihood of the development of posttraumatic arthritis or malalignment, chronic rupture of the syndesmosis should be identified and addressed to prevent long-term pain May 21, 2018 · Medial column (deltoid ligament) integrity is of key importance when considering the stability of isolated lateral malleolus ankle fractures. Unstable trimalleolar fractures. Latent diastasis occurs when the ankle mortise does not appear to be widened on normal radiographs. We introduce a novel opening wedge distal tibial osteotomy procedure (mortise-plasty) with rigid plate fixation combined with synthetic the ankle. Seventy per cent of ankle fractures are unimalleolar injuries, the Weber B-type of fibula fracture being by far the most common type. 1. An intraoperative fluoroscopic mortise view of the ankle that shows a widening more than 2 mm in the syndesmosis suggests an unstable injury that necessitates fixation. A CT scan may be required to further characterize the fracture pattern and for surgical planning. Cotton test , the talus is ‘rocked’ from side to side in the ankle mortise by applying alternating medial and lateral stress to the talus. We found a high rate of positive stress radiographs for patients who presented with an isolated fibular fracture and an intact ankle mortise on the initial radiographs. The tenon (or tongue) is the talus. A. Dec 15, 2010 · There are two positions of the foot in which the flexible ankle joint becomes a rigid and vulnerable system: extreme supination and pronation. Nonviable soft tissue envelope. 1–8 In this particular fracture type, the ankle mortise is either stable or unstable depending on accompanying soft tissue injury. The ankle is a diarthrodial joint (Figs. Patients with ankle-related symptoms often present to a wide range of specialties, including primary care, orthopedic, and emergency medicine providers. In a normal ankle, this should show a uniform width of space through the mortise joint space. The mortise (the socket) comprises the lateral malleolus, the tibial plafond, and the medial malleolus. This projection is the most pertinent for assessing the articulation of the tibial plafond and two malleoli with the talar dome, otherwise known as the mortise joint of the ankle 1,2. We report the characteristics of mortise widening in MHE, its progression over time, and the resultant ankle pain and function at skeletal maturity. Frank diastasis differs in that the ankle-mortise widening can easily be seen on routine x-ray films. Nov 1, 2022 · Ankle valgus is commonly reported in patients with multiple hereditary exostoses (MHE). (normal <6mm between tibia and fibula 1 cm proximal to tibial plafond) Stress views can reveal ligamentous injury. With ankle dorsiflexion, the fibula laterally translates, proximally migrates, and externally rotates. In the absence of osteochondral or soft tissue interposition, these articulations often recoil back to normal alignment when unloaded (9) . Normally, the talus sits in the ankle “mortise,” articulating with the weight-bearing tibial plafond, as well as the articular facets of the medial and lateral malleoli. Stability Egol 15 evaluated 101 patients with evidence of an isolated fibular fracture and an intact mortise seen on a standard ankle trauma radiograph series, finding a positive stress radiograph (defined as > 4 mm of medial clear space widening) in 65% of patients and low sensitivity of clinical signs in predicting ankle instability, highlighting the Oct 1, 2020 · “Chronic syndesmotic injury covers a broad range of symptoms and pathologies.

The contralateral ankle is often imaged for comparison of “normal” laxity. The dramatic change in ankle joint mechanics that can occur with even mild syndesmotic injuries is a likely contributor to both the prolonged recovery and long-term dysfunction Widening of the ankle mortise. External rotation stress view may reveal occult lesions. A syndesmotic injury of the tibiofibular joint arises from an external rotation force acting on the foot leading to eversion of the talus within the ankle mortise, and increased dorsiflexion or plantar flexion.
