UNASSIGNED: The aim of the study was a case report of a right-sided recurrent giant cell tumor of the distal end of the femur.
UNASSIGNED: A case of a 25-year-old male patient with a history of recurrent giant cell tumor of the right distal femur who presented with chief complaints of pain over right distal femur and stiffness in the right knee for 2 years with restricted knee movement and is unable to walk. He was diagnosed with recurrent giant cell tumor of the right of the distal femur and was treated with wide excision with mega prosthesis reconstruction.
UNASSIGNED: Wide excision with mega prosthesis reconstruction showed a good functional range of motion with early rehabilitation, stability, and mobility of joints.
UNASSIGNED: We recommend wide excision and reconstruction with mega prosthesis is an effective method compared to sandwich technique and nailing and can be successfully done in the case of recurrent giant cell tumor of the distal femur with a good outcome, functional range of motion, stability, and mobility of the joint with early rehabilitation though it is a technically demanding surgery. The knee joint could have been salvaged and the need for more extensive surgery could have been prevented, had the diagnosis of recurrent giant cell tumor was made earlier.

Giant cell tumors (GCTs) located in the distal radius are likely to recur, and the treatment of such recurrent tumors is very difficult. Here, we report our clinical experience in distal radius reconstruction with vascularized proximal fibular autografts after en-bloc excision of the entire distal radius in 17 patients with recurrent GCT (RGCT) of the distal radius.
All 17 patients with RGCT in distal radius underwent plain radiography and/or magnetic resonance imaging (MRI) of the distal radius as the initial evaluation after hospitalization. Then the distal radius were replaced by vascularized proximal fibular autografts after en-bloc RGCT resection. We assessed all patients by using clinical examinations, plain radiography of the wrist and chest, and Mayo wrist scores in the follow-ups.
After an average follow-up of 4.3 years (range: 1.5-10.0 years), no lung metastasis or local recurrence was detected in any of the 17 patients. In total, 14 patients had excellent or good functional wrist scores, 16 were pain free or had occasional pain, and 15 patients returned to work. The mean range of motion of the wrist was 101° (flexion-extension), and the mean grip strength was 77.2 % of the contralateral normal hand.
En-bloc excision of the entire distal radius and distal radius reconstruction with a vascularized proximal fibular autograft can effectively achieve local tumor control and preserve wrist function in patients with RGCT of the distal radius.

BACKGROUND: Giant cell tumour of bone (GCT) is a common benign primary bone tumour, seen commonly in the distal Femur, proximal Tibia and distal Radius. Very few cases of GCT are reported in distal humerus. We report an unusual presentation of recurrent Giant cell tumour in a 25 year old male in the medial condyle and epicondyle of left Humerus.
METHODS: Patient presented elsewhere with lytic lesion of left elbow three years ago. As it is an uncommon site for tumors, it was misdiagnosed as tuberculous osteomyelitis and was inadequately curetted. Patient presented to us with recurrence of tumor one year after the primary surgery. We did en-bloc resection of the tumour, with judicious removal of partial trochlea. Though reconstruction was planned, it was found to be not necessary as the elbow was stable per-operatively. Patient regained near normal movements of the elbow with no instability. His Mayo Elbow Performance score improved from 30 to 85. There is no recurrence or metastasis of the tumor in the two-year follow-up.
CONCLUSIONS: Though bone tumors are rare in distal Humerus, biopsy is needed to confirm the diagnosis of any lytic lesion in this region for proper management.
