Radiologic Analysis of Hindfoot Alignment: Comparison of Mary, Long Axial, and Hindfoot Alignment Views. The valgus position of the calcaneus has led to combined talocalcaneal and subfibular lateral hindfoot impingement with edema and cystic changes in the distal fibula and osteoarthritis as well as scar tissue formation between the lateral talus and calcaneus. If the navicular is ossified, it will be laterally displaced. Calcaneal osteotomy is often necessary to correct hindfoot valgus and lateral hindfoot impingement [ 7 ]. Subcortical cyst formation is also prominent within the mid talus and lesser so at the distal fibula with subfibular soft tissue edema. This can include talocalcaneal, subfibular, and /or talocalcaneal-subfibular impingements. A surgical technique using a medial displacement calcaneal osteotomy (MDCO) combined with a lateral wall exostectomy was a safe and effective treatment for severe calcaneofibular impingement. 193 (3): 672-8. radiopaedia.org.

They include femoroacetabular impingement, iliopsoas impingement, subspine impingement, and ischiofemoral impingement around the hip; patellar tendon-lateral femoral condyle friction syndrome; iliotibial band friction syndrome; and medial synovial plica syndrome in the knee as well as talocalcaneal impingement of the hindfoot (Table). Osteoarthritis and occult lateral talar process fractures also produce talar facet and lateral talar bone marrow edema. Cyst formation and/or sclerosis in this region that is visible on plain radiographs or on computed tomographic scans performed without weight-bearing should create suspicion of impingement. Posterior tibial tendon dysfunction and lateral ankle pain in a patient with valgus deformity of the hindfoot. Lateral Hindfoot Impingement - Radsource. In cases of sinus tarsi narrowing, calcaneofibular impingement is unlikely to occur without sinus tarsi impingement. Biomechanically, LHI is the sequela of lateral transfer of weight bearing from the central talar dome to the lateral talus and fibula. 90 (1070): 20160735. The pain originates when the subtalar joint repetitively jams (impinges) while performing weight-bearing activities. No accessory navicular.

Because this injury involves ligaments located above the ankle joint it is sometimes called a high ankle sprain. Surgical Technique for Management of Severe Calcaneofibular Impingement: Case Series:. Hindfoot valgus, EA-TCI and EA-CFI were present relatively commonly on review of ankle MRI studies in patients referred from a specialist Foot and Ankle Unit but were commonly under-reported highlighting a relative lack of awareness of hindfoot malalignment on ankle MRI amongst musculoskeletal radiologists, which could impact negatively on patient management. The anterior impingement syndrome of the ankle is a strangulation that can be caused by soft tissue, like the joint capsule or scar tissue, and hard tissue which refers to bone tissue. Frequent questions Filter. this condition is related to hindfoot valgus malalignment and lateral shift of the calcaneus bone causing to abnormal bony contact between the talus and calcaneus bones more obviously at the posterior peripheral margin of the sinus tarsi and occasionally causing to development of "neofacets" at the sinus tarsi, as well as at the distal of fibula 2. Lateral calcaneal wall decompression has been used successfully to relieve pain in patients who have calcaneofibular impingement. All patients underwent tomosynthesis, radiography, and computed tomography . decreased joint space involving lateral aspect of posterior talocalcaneal joint. 2010;39(11):1103-8.

Lateral hindfoot impingement A 31-year-old female asked: I recently had a mri on my ankle due to chronic pain and swelling on the lateral side. Calcaneofibular impingement is characterized by lateral hindfoot pain and is commonly resulting from calcaneal fracture malunion or severe flatfoot deformity. Moderate hindfoot valgus. It is the most frequently affected component with tears usually occurring at the superior and distal portion at the junction to the tibiospring ligament 1,2. Interreader agreement of hindfoot alignment measurements is slightly better on long axial view radiographs than on hindfoot alignment view radiographs. Although the majority of research in PCFD is concerned with abnormalities of the medial column, PCFD will increase stress on the lateral column. Check for errors and try again. Extra-articular lateral hindfoot impingement syndrome is a non-traumatic cause of ankle impingement. 50 (7): 1317. Early detection of impingement using MRI may be beneficial for successful surgical results [9, 10]. hind foot valgus (angle >20 degrees) extra articular surface edema seen involving lateral talar process and calcaneal sulcus with areas of underlying sclerosis. minimal thickening of calcaneofibular ligament. Most commonly, the mechanism that causes the repetitive jamming is a foot that pronates excessively (a foot where the arch flattens and rolls in as the heel rolls out). There appear to be two frequently occurring extra-articular sources of bone impingement in the lateral aspect of the hindfoot in adults with symptomatic severe flatfoot deformity. Extra-articular lateral hindfoot impingement syndrome refers a non-traumatic cause of ankle impingement. Anterolateral ankle impingement is one of the impingement syndromes of the ankle and can occur as a posttraumatic sequel of an inversion injury 1-6.
