Two rare cases of Giant cell tumor of Distal Ulna.

• Giant cell tumours are locally aggressive with a relatively high recurrence rate. • Common sites are distal femur, proximal tibia and distal radius. • Contained lesions at these sites managed by joint preservation procedures such as extended curettage with cementing or bone graft. • GCT in spine, calcaneum and distal ulna are rare, with no uniform consensus regarding the ideal treatment. Giant cell tumours, though benign, are locally aggressive bone tumours with a relatively high recurrence rate. These usually occur in distal radius, distal femur, proximal tibia and humerus. Treatment options for contained lesions at these sites include joint preservation procedures such as extended curettage with cementing or bone graft. GCT in spine, calcaneum and distal ulna are rare, with no uniform consensus regarding the ideal treatment. Here we report two cases of GCT distal ulna managed with extended curettage and polymethylmethacrylate cementing showing good functional and radiological outcomes without signs of recurrence during 2 years follow up.
