CASE 25: Fracture-dislocation following metastasis of thyroid cancer to the left hip bone (acetabulum)

• 63-year-old man
• No known illnesses.
• The hip pain, which had been present for 4 months, gradually worsened and became impossible to walk.
• The patient's examination revealed shortening of the left leg and severely restricted movement and tenderness in the left hip.
• The patient, whose biopsy revealed thyroid cancer metastasis, also had involvement solely in the thyroid tissue.
• After the tumor tissues in the left hip were removed in one piece with clean margins (resection), the resulting cavity was reconstructed with a tumor prosthesis.
• The patient also underwent a procedure to remove the tumorous thyroid tissue, performed by the relevant specialist.
• The patient, whose stitches were removed in the second week after surgery, was referred for radioactive iodine treatment.

Before surgery: X-rays, MRI, and CT scans show damage, a fracture, and a large tumor tissue in the left hip bone.

Postoperative: The X-ray shows reconstruction with a tumor prosthesis after removal of the tumorous bone and soft tissue (internal hemipelvectomy).
