Over the adult years, the dysplastic bone leads to the development of an asymmetric talonavicular arthritis with the talar head shifting laterally and plantarly, thus driving the subtalar joint into varus. From a diagnostic point of view, the condition may be difficult to differentiate from an avascular necrosis or even a stress fracture of the navicular, but fragmentation is the result of a mechanical impairment rather than a biological dysfunction.Standardized weight-bearing radiographs (anteroposterior and lateral views) of both feet are usually enough to diagnose MWD. Other imaging modalities such as multi-detector computed tomography and magnetic resonance imaging in early cases for the differential diagnosis can add additional details on the amount of cartilage affected, bone stock, fragmentation, and associated soft tissue injuries. Failure to identify patients with paradoxical flatfeet varus may lead to an incorrect diagnosis and management. Conservative treatment with the use of rigid insoles is effective in most patients. A calcaneal osteotomy seems to be a satisfactory treatment for patients who fail to respond to conservative measures and a good alternative to the different types of peri-navicular fusions. Weight-bearing radiographs are also useful to identify postoperative changes.</p>","PeriodicalId":49545,"journal":{"name":"Seminars in Musculoskeletal Radiology","volume":null,"pages":null},"PeriodicalIF":1.4,"publicationDate":"2023-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"9583371","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A BSI is caused by recurring microtrauma to the cortical or trabecular bone exceeding the repair capacity of normal bone. The most frequent fractures at the ankle are low risk, characterized by a low risk for nonunion. These include the posteromedial tibia, the calcaneus, and the metatarsal diaphysis. High-risk stress fractures have a higher risk for nonunion and need more aggressive treatment. Examples are the medial malleolus, navicular bone, and the base of the second and fifth metatarsal bone.Imaging features depend on the primary involvement of cortical versus trabecular bone. Conventional radiographs may remain normal up to 2 to 3 weeks. For cortical bone, early signs of BSIs are a periosteal reaction or the \"gray cortex sign,\" followed by cortical thickening and fracture line depiction. In trabecular bone, a sclerotic dense line may be seen. Magnetic resonance imaging enables early detection of BSIs and can differentiate between a stress reaction and a fracture.

Congenital disorders include congenital talipes equinovarus or congenital clubfoot, metatarsus adductus, skewfoot, congenital vertical talus, and tarsal coalition.Some of these deformities are frequent and easily diagnosed based on clinical features, but clinical overlap between pathologies can be challenging. Thus imaging plays a paramount role in evaluating these patients.

Newconcepts in anatomyand their relevance to maintaining normal biomechanics of the foot and ankle have emerged recently, requiring radiologists to provide more detailed information in their reports, so accurate treatment, conservative or surgical, can be planned. The issue begins with new concepts on ankle and foot sprain injuries. Alvaro Cerezal and colleagues describe ankle instability and how formerly overlooked injuries can influence patient outcome and lead to medial and rotatory instability. The accompanying exquisite drawings along with high-resolution images are very helpful. Inge C.J. Koetser and colleagues review midtarsal sprain. Although ankle sprain has been studied extensively in clinical and radiologic studies, midtarsal sprain did not receive the same attention. But it is more frequent than previously thought and should not be overlooked. This issue also reviews the complications of ankle sprain. Thomas Armstrong et al summarize impingement syndromes. Important complications of ankle sprain are osteochondral injuries on the talar dome. From the old scheme of Berndt and Harty, new consensus classifications have emerged with greater clinical and surgical correlations. Logan P. Haug and colleagues propose a practical guideline on how to deal with these frequent lesions from a clinical perspective. Bone stress injuries are particularly frequent in the lower extremity especially in athletes. Dr. Jungmann and Dr. Schaeffeler will review MRI diagnosis and how to differentiate stress reaction from fractures, as well as the different prognostic factors. Müeller-Weiss disease is usually managed by orthopaedic and foot surgeons, but it is crucial to understand the diagnosis criteria and differential diagnosis. Javier Carrascoso and Manuel Monteagudo, together with their colleagues, have presented an excellent overview of this disease. The Achilles tendon is the human body’s largest tendon. Injury can limit the career of a promising young athlete. Progressive pathologic changes correlate with imaging findings, andMeghanMoriarty andWilliamMorrison provide an informative overview.

Ana Isabel Garcia-Diez and her team review the challenges related to diagnosing the diabetic foot. Symptoms of many rheumatologic diseases begin in the foot and ankle. To be precise and accurate, knowledge of the patterns of the different rheumatologic disorders is essential. Chiara Giraudo et al present a helpful overview. P.
