Talus osteohondroma with syndesmosis problem; case report.

introduction and importanceOsteochondroma, commonly known as exostosis, is a benign osteocartilaginous mass lesion frequently encountered in orthopaedic clinics. While its benign nature is of little concern, the impact on surrounding tissues can be significant, especially in the case of exostosis located in the distal tibia and fibula, which can damage the syndesmosis. CASE PRESENTATION: This report presents a rare case of exostosis of the talus that has progressed into the syndesmosis, causing distinct clinical and radiographic symptoms. The patient underwent excision of the lesion through the posterolateral ankle approach, and our main concern was about the approach to the syndesmosis. Ultimately, open reduction and screw fixation were performed for the patient. CLINICAL DISCUSSION: Exostosis in the talus area is generally uncommon in the literature review, and the presence of the lesion in the posteromedial surface area, as well as its entry and damage to the syndesmosis area, is even less common. Diagnosing the lesion through appropriate methods and a multidisciplinary team approach is crucial for correct diagnosis and treatment. Different approaches to managing syndesmosis have been reported, and suitable treatment for these cases is required.

conclusionIn conclusion, correct diagnosis and excision of the exostosis lesion are essential, but it is also necessary to appropriately identify and manage its adverse effects. The selection of an appropriate treatment strategy for managing these lesions is crucial.
