Abstract

Aneurysmal bone cysts (ABCs), a misnomer pathology, are osteolytic bone neoplasms characterized by several sponge-like spaces. ABCs commonly affect vertebral metaphyses, flat bones or long bones; frequently recorded in 10-30 yrs population, they are commonest pelvis benign tumor in pediatric population. Curettage, marginal resection and cell killing methods at cyst margins are most commonly used surgical approaches, but often cyst dimensions require bone filling and use of fixation devices to ensure load bearing capabilities of lesioned bone (1). Within a clinical study, we developed a fixation devices free surgical methodology to treat ABC, ensuring both immediate loading and robust bone regeneration.
