[Long-term results of the treatment of a giant cell tumor with en-bloc resection and unconventional hip arthroplasty with ipsilateral knee arthrodesis. Clinical case report and literature review].

Giant cell tumor (GCT) is an aggressive benign neoplasia that accounts for 5% of primary bone tumors and 20% of all benign bone tumors. It appears almost exclusively after skeletal maturation, between 20 and 40 years of age, and is predominant among females. We report the case of a 39 year-old male patient who in 1988 sustained a left hip fracture in a pathological area.

Surgical management of tumors located in the spine and the pelvis involves greater difficulty. Moreover, these tumors are usually very large and vascularized. Preoperative embolization of the internal iliac artery is a relatively safe procedure that may reduce the risk of bleeding and local recurrence in the case of benign tumors.
