Abstract :

Aneurysmal bone cysts are rare benign osteolytic skeletal tumors that most commonly occur in the first two decades of life, affecting the metaphysis of long bones. It presents as blood–filled cavitary septate spaces with blowout distension of the cortex, with often a thin rim of intact periosteum, and a fious cyst wall consisting of fioblasts and histiocytes. The pathogenesis remains controversial; when occurring de novo, it is believed to be the result of local haemorrhage into bone. Treatment consists of extended curettage and use of bone graft and bone graft substitutes. Because of its excellent osteoconductive properties and mechanical strength, calcium hydroxyapatite has emerged as an excellent choice in treating benign bone defects. We present a case of a distal tibial aneurysmal bone cyst in a young female treated by using hydroxyapatite crystals and autologous cortical iliac crest strut graft.
