Prestige lp prosthesis

This was a retrospective and comparative study of patients undergoing two-level HS in our hospital from January 2011 to July 2020. Informed consent was obtained from all patients, and the study protocol was approved by the Ethics Committee of our institution (Project License number: 20190946). The eligibility criteria required a diagnosis of refractory CDDD with symptomatic radiculopathy and/or myelopathy at two contiguous levels from C-3 to C-7 confirmed by preoperative radiographical findings. Exclusion criteria included any prior spine surgery at operative levels, severe facet arthritis, fracture, infection, tumor, and severe osteoporosis (T-score ≤ − 2.5). The implant was selected based on preoperative segmental features. In this regard, CDA was performed at a mobile and soft-herniation segment. ACDF was performed in the case of segmental instability (sagittal plane translation >3.5 mm or angular motion >20°), angular motion <2°, a disc height loss of >50%, or severe facet joint degeneration. In all cases, a Prestige-LP prosthesis (Medtronic Sofamor Danek, Memphis, TN) was inserted into a well-prepared arthroplasty level, and a Zero-P implant (Synthes, Oberdorf, Switzerland) packed with β-tricalcium phosphate was used as a stand-alone arthrodesis implant. The operations were conducted via an anterior right-sided approach by the same senior spine surgeon.
