Obtain an urgent orthopedic consultation for calcaneal fractures since open reduction and internal fixation is usually necessary. Imaging of the Lisfranc injury. Malicky ES Crary JL Houghton MJ et al. Lateral hindfoot impingement is characteristically not related to an acute injury but to chronic hindfoot valgus malalignment. Medline. These clinical symptoms are not specific and may also be encountered in patients with subtalar degenerative arthritis sinus tarsi syndrome and other disorders affecting the hindfoot region. Transchondralosteochondral talar dome fracture is a rare injury that often presents as a nonhealing ankle sprain and is caused by small cartilaginous avulsions or body chips in tibial articulation. Symptoms often include hindfoot pain on weightbearing swelling and tenderness in the region anterior and inferior to the lateral malleolus and limited subtalar range of motion. The apex of the angle of Gissane is at the location of chronic talar impact with lateral hindfoot impingement and this is the center of the bony changes therefore the angle of Gissane or calcaneal angle can be used as a term to identify the calcaneal location of pathology. AJR Am J Roentgenol. Injury. The procedure has evolved from early use of a bone block placed into the sinus tarsi for extraarticular arthrodesis to placement of a metal or plastic implant configured to specifically block the anterior translation of the lateral talar process towards the floor of the sinus tarsi aiming to limit hindfoot eversion .

Compartment syndrome is the most dangerous acute complication of foot fractures. A Tweighted sagittal image in a yearold male with ankle pain and swelling shows features characteristic of sinus tarsi syndrome with absence of fat signal at the sinus tarsi arrow. Note the absence of signs of osteoarthritis at the adjacent posterior subtalar joint. The marginal erosions of RA may also mimic the bony changes of lateral hindfoot impingement but erosions and synovitis are generally also present elsewhere clarifying the diagnosis. Foot Ankle Clin

According to Dale gluconeogenesis occurs in the liver due to the action of et al talar fracture patterns cannot glassell park elementary school be characterized by radiography alone and CT is critical for detecting and characterizing talar fractures. Radiographs may be normal and injuries cannot be distinguished clinically from ankle sprains. Lateral hindfoot impingement with extraarticular talocalcaneal impingement and subfibular calcaneofibular impingement. Emergency department evaluation and management of foot and ankle pain. Longterm complications of foot fracture include the followingSubcortical bone marrow edema characteristically involves both opposing aspects of the Gloucester premium outlets talus calcaneus or fibula a. Medline. Sep. The location of the bone marrow edema is characteristic at the extraarticular region at the inferior apex of the lateral talar process and at the immediately subjacent aspect of the calcaneus at the apex of the angle of Gissane a. Subluxation at the talocalcaneal joint has been shown to occur in symptomatic adults with acquired flat foot involving a lateral translocation of the calcaneus into valgus malalignment with the subluxation greater at the anterior and middle talocalcaneal articular facets than at the posterior facet leading to reduction of articular contact surfaces at these joints .

Medline. This measurement has limitations related to the short segment of tibia included on ankle MRI exams being insufficient for an accurate long axis determination and the medial wall of the calcaneal tuberosity gradually slopes towards vertical also in cases of severe valgus malalignment so it is important to perform the measurement between the sustentaculum and the calcaneal tuberosity available slice selection also somewhat limits reproducibility.

    Medline. Extraarticular lateral hindfoot impingement with posterior tibial tendon tear MRI correlation. Its development relates to hindfoot valgus malalignment and a lateral shift of the calcaneus which may lead to abnormal bony contact between the talus and calcaneus specifically at the posterior peripheral margin of the sinus tarsi and sometimes also the development of neofacets at the sinus tarsi as well as at the fibula and adjacent calcaneus. A fatsuppressed coronal proton densityweighted image in a yearold woman with sequelae of remote displaced fractures arrows with a hindfoot valgus fixed deformity and year history of diffuse ankle pain. The bony changes sometimes are seen to also involve the adjacent subcortical region of the anterosuperior calcaneal process a however if bone marrow edema is present all along the cortex around the margins of the sinus tarsi this would not be characteristic and would instead suggest a diagnosis of sinus tarsi syndrome
