The diagnosis of posterior hindfoot pain may prove to be elusive as there are many potential causes of hindfoot pain, including both soft tissue and osseous abnormalities. This is a case presentation of os trigonum syndrome, with the diagnosis suggested by magnetic resonance imaging (MRI), confirmed by ultrasound, and treated with os trigonum resection. Specific findings of os trigonum syndrome can be seen on MRI, including bone marrow edema pattern and high signal intensity in the synchondrosis as well as in the surrounding soft tissues. Diagnostic injections performed with imaging guidance can help confirm the diagnosis in equivocal cases. Diagnostic and interventional imaging procedures can help confirm the diagnosis of os trigonum syndrome in a patient presenting with hindfoot pain.
后足疼痛的诊断可能难以确定，因为后足疼痛有许多潜在的原因，包括软组织和骨骼异常。这是一例 os trigonum 综合征的病例报告，其诊断依据为磁共振成像（MRI），超声检查予以证实，并采用 os trigonum 切除术进行治疗。MRI 可显示 os trigonum 综合征的特定表现，包括骨髓水肿模式以及骺板和周围软组织的高信号强度。在有疑问的情况下，行影像学引导下的诊断性注射有助于明确诊断。在出现后足疼痛的患者中，诊断性和介入性影像学检查有助于明确 os trigonum 综合征的诊断。
