Abstract

Aim: Tarsal coalition is the partial or complete fusion of the bones of the tarsus, which may be joined by bone, cartilage or connective tissue. The incidence of tarsal coalition in the population is about 1%, but some authors claim that it could be even higher because asymptomatic cases are usually not diagnosed. In this article, we will try to demonstrate the diagnostic value of magnetic resonance in the radiological management of patients with suspected tarsal coalition, using our patient as an example. Case report: A 16-year-old boy with no history of trauma to the right leg presented to our department with occasional pain in the area of the right foot that had increased in severity over the past few months, worsening after prolonged standing or sports activity and decreasing after a period of rest. Conventional x-rays were not suggestive of a tarsal coalition. The radiological work-up was extended to include magnetic resonance imaging, which confirmed the changes consistent with a fibrous calcaneonavicular coalition. Conclusions: In the initial radiological management of tarsal coalitions, conventional radiography and computed tomography are commonly used because of their simplicity and availability and have the highest sensitivity in diagnosing synostosis. In the case of a justified clinical suspicion of a tarsal coalition, it is recommended to consider extending the radiological treatment with magnetic resonance imaging, which has the highest sensitivity for detecting non-osseous coalitions, can clearly show osseous coalitions, allows a more precise analysis of the bone tissue and possible pathology of the surrounding soft tissues and, like computed tomography, can also be used for preoperative planning. In addition, we do not expose patients, who are generally younger and still growing and developing, to harmful ionising radiation.
