Bone Graft Options for Spine Fusion in Adolescent Patients with Idiopathic Scoliosis

Adolescent idiopathic scoliosis （AIS） is one of the most prevalent diseases among teenagers, with an incidence rate of 1-3% worldwide, and at least 0.02% of patients require surgical treatment. The ＂gold standard＂ procedure is instrumentation and fusion of 10 or more vertebrae with forceful correction of the deformity.Although autogenous bone grafts are the ＂gold standard＂ for spine fusion, significant progress has been made in discovering bone graft alternatives, including freeze-dried allograft, demineralized bone matrix （DBM）, triosite ceramics, and bone marrow aspirate （BMA）, which have been used as substitutes for iliac crest in AIS surgery.
