CASE 32: Recurrent Chondrosarcoma of the Proximal Femur

• 66-year-old female patient
• He underwent multiple surgeries due to proximal femoral chondrosarcoma.
• The prosthesis was treated due to infection.
• The patient presented with complaints of swelling and pain in the left hip and thigh.
• The patient presented with a severe shortening of the left leg and a neurological deficit.
• Internal hemipelvectomy with proximal femur resection was performed due to chondrosarcoma recurrence.
• A pre-prepared antibiotic spacer was placed in the resulting gap.

Preoperative examination: X-ray shows proximal femoral absence replaced by a spacer, along with hip joint deformity and soft tissue calcification.

Preoperative: MRI shows a large tumor tissue with irregular borders, accompanied by a large soft tissue mass extending to the hip joint.

During the operation: The incision line and the dissection and exposure of the vascular and nerve bundles are visible.

Postoperative: Clinical view of the space created after resection, antibiotic spacer placement, and the removed tumor tissue.

Postoperative: X-ray shows proximal femur resection and internal hemipelvectomy followed by antibiotic spacer placement.
