Case report on metastatic pelvic bone tumor treated with frozen autograft by liquid nitrogen.

Introduction And Importance: Frozen autograft recycling has been used for biological reconstruction of bone defects following tumor excision, more commonly in extremities. We report on the histological outcome of a pelvic recycled frozen autograft.

Case Presentation: We investigated the pelvic frozen autograft removed in 2 years and 8 months after surgery because of soft tissue recurrence in pelvic floor.

Is It Possible and Safe to Perform Acetabular-preserving Resections for Malignant Neoplasms of the Periacetabular Region?

Background: Primary malignant tumors located near the acetabulum are usually managed by resection of the tumor with wide margins that include the acetabulum. These resections are deemed P2 resections by the Enneking and Dunham classification. There are various methods to perform the subsequent hip reconstruction.

Giant cell tumor of the humeral head treated by denosumab: Implication to shoulder surgeons.

Giant cell tumor is a benign bone tumor that is commonly encountered. The optimal treatment of a giant cell tumor which causes extensive bony destruction is controversial. Recent studies on the receptor activator of nuclear factor κB ligand antagonist denosumab may offer a new treatment option for these patients.

Unusual presentations of osteoarticular tuberculosis in two paediatric patients.

Tuberculosis is a universal mimicker and thus could be a differential diagnosis of any osteolytic lesion. Bone biopsy is crucial in these cases for culture and histological proof of tuberculous infection. This is a case report of two paediatric patients with unusual presentations of tuberculosis.
