Removal of osteoblastoma of the talar neck using standard anterior ankle Arthroscopy：A case report

INTRODUCTION: Osteoblastoma of the talus, a benign tumor, is rare in orthopedics. The choice of treatment is usually open surgery for excision of tumor. Limited data is available concerning arthroscopic approaches. PRESENTATION OF CASE: A 36-year-old male patient was evaluated for pain and swelling of the left ankle joint. Based on the findings of physical examination, X-rays and MRI investigations, the tumor was isolated. Standard anterior arthroscopic surgery was performed due to ankle pain. A diagnosis of osteoblastoma of the talar neck was made following the pathological survey. He had no recurrent pain and normal joint mobility 5 years postoperatively during he was regularly followed up. DISCUSSION: Osteoblastoma of the talar neck is slowly progressive and it is a palpable painful mass. Open or arthroscopic surgery can be performed. Treatment strategies are decided on according to the tumor's location, extent and size. Some advantages of arthroscopic surgery are wide visualization areas, minimally invasion, low morbidity, no necessity for casting and immobilization, early rehabilitation and quick recovery. CONCLUSION: In conclusion, arthroscopic management can be successful in selected patients with small benign tumor localized to the ankle joint.
