Auguste, k., chin, c., acosta, f., and ames, c., (2006) expandable cylindrical cages in the cervical spine a review of 22 cases.J neurosurg spine, 4: 285-291.The authors discussed their experience in using expandable cylindrical cages (ecc) in the reconstruction of the cervical spine in 22 patients with various pathological conditions.All patients underwent a standard anterior cervical corpectomy.The ecc constructs were supplemented with posterior instrumentation in patients with neoplastic processes or those requiring two-or multilevel corpectomies and with a preoperative kyphotic deformity greater than 15?.The synthes in-space implant was used for the percutaneous implantations.Native bone harvested from the corpectomy site was used as bone graft material.In patients with osteomyelitis or metastatic cancer the competitor's bone material product was used.Overall, the combination of corpectomy and ecg-augmented fusion led to improvements in kyphotic deformities, restoring structural support, and appeared to be well tolerated.(b)(4).This report reflects information received by fda in the form of a notification per 803.22 (b)(2).
