THE DIFFICULTY OF THE DIAGNOSIS OF AN ISOLATED PROXIMAL TIBIOFIBULAR JOINT DISLOCATION: A CASE REPORT AND REVIEW OF LITERATURE

Introduction:An isolated dislocation of the proximal tibiofibular joint is uncommon injury. The diagnosis can be easily missed. In this case report, we expose how avoid missing out on the diagnosis and we expose a special maneuver which facilitating the open reduction. Case Report: We report the case of a 31-year-old man presented at emergency after right knee during football game. Initially physical examination objectives a moderate swelling and a local pain on the lateral side of the right knee. The anteroposterior and lateral radiographs was considered normal. The diagnosis of lateral meniscal injury was admitted. After one week, reexamination objective a tender bony prominence over the anterolateral aspect of the knee. Radiological investigations confirms the diagnosis of a proximal tibiofibular dislocation. An open reduction was performed. At final follow-up, the patient don't presents any complaints, with complete range of motion of the knee and the ankle. Conclusion:The proximal tibiofibular joint dislocation is rare entity. The early diagnosis can be missed easily if no awareness of this injury is present. The clinical presentation can mimes a lateral meniscal or lateral ligaments injuries. CT cofirms diagnosis if X-ray are insuffisent. Often, early diagnosis allows a closed reduction without surgery.
