Giant cell tumour of bones is an unusual neoplasm that accounts for 4% of all primary tumours of bone, and it represents about 10% of malignant primary bone tumours with its different grades from borderline to high grade malignancy (1). GCT generally occurs in skeletally mature individuals with its peak incidence in in the third decade of life. Distal femur and proximal tibia are the commonest sites followed by distal radius (2), less than 4% of these tumours are known to affect the ankle joint, but the tumour’s biological behavior at this site is quite unpredictable. Moreover, restoring the ankle joint functionality following tumour resection is a challenging task.
Case Summary: 27 year old female presented with pain over right ankle since last two years. Biopsy was suggestive of Giant Cell Tumor of lower third tibia. We managed this case with intralesional curettage using phenol and bone cement as an adjuvant and reconstruction of defect by cementation along with locking plate.
Conclusion: In cases of GCT, the management depends upon the various factors such as site, age, involvement of the bone, extent of bone involvement and whether there is articular involvement or not. Extra-articular GCT can be managed with extended intralesional curettage. Bone cement plays a dual role as an adjuvant as well as an agent for reconstruction of the defect.
