Abstract :Objectives. Nora’s disease is a mesenchymal bone tumor with controversial diagnosis and treatment due to the benign but locally aggressive course and high recurrence rates. Methods. A retrospective analysis was made of patients diagnosed with Nora’s Disease at Ankara University Orthopedics and Traumatology Clinic. The evaluation was made of the age of the patient, gender, symptoms, lesion location, trauma history, treatment choice and recurrence rates during follow-up. Results. Excision was applied to 6 patients diagnosed with Nora’s disease, and in 1 patient an additional autograft and internal fixation were required. Recurrence was observed in 3 patients, 2 of whom underwent revision surgery and one who did not as there no patient complaints. Conclusions . Nora’s disease is problematic for orthopedic surgeons as there are difficulties in diagnosis, there is no absolute treatment algorithm, recurrence potential is high, and there are limited additional treatment choices. Therefore, treatment and follow-up at clinical center’s dealing with orthopedic tumor surgery can be considered appropriate.
