title: A new zero-profile, stand-alone Fidji cervical cage for the treatment of the single and multilevel cervical degenerative disc disease.
abstract: To investigate the clinical and radiological results of the new zero-profile, stand-alone Fidji cervical cage to treat single- and multiple-level cervical DDD, and evaluate the safety and efficiency. Between October 2011 and July 2014, 72 consecutive patients (41 males and 31 females; mean age 50.9years [range, 33-68years]) with cervical DDD who underwent surgery and were followed for more than 2years were enrolled in this study (mean 31.1months, range 24-47months). The study compared clinical outcomes, radiologic parameters and complication rates. The SF-36, VAS, NDI, and JOA scores of all patients were improved significantly after surgery at any time point. (all p<0.05). The C2-C7 Cobb angle and the disc height index (DHI) of all patients were improved significantly after surgery at any time point (all p<0.05). From 3months after surgery to final follow-up the DHI showed a significant reduction comparing 1week after surgery (all p<0.05). The fusion rates were 91.7% (66/72) and the radiologic mean fusion time was 9.9months. Radiological evidence of adjacent segment degeneration (ASD) was observed in 4/41 patients (9.8%). Postoperative complications included epidural hematoma, hoarseness, dysphagia, axial neck pain, and subsidence. The zero-profile, stand-alone Fidji cervical cage for ACDF can be considered an effective, reliable and safe alternative procedure in the treatment of cervical DDD.
