The Plate cage Benezech implant as an alternative to autologous bone graft in the treatment of cervical spondylosis: clinical and functional outcome.
Plate cage Benezech (PCB) is a titanium-made implant introduced recently in spinal surgery as a new substitute for autograft in cervical spine interbody fusion. It has a plate attached to the anterior surface of the cage to prevent any displacement of the cage, and to provide additional support in patients with dynamic instability. A small number of studies have shown the PCB cage is safe and efficient. We conducted a retrospective study on 54 consecutive patients with cervical spondylosis who underwent anterior cervical discectomy and interbody fusion (ACDF) with a PCB cage between the year 2001 and 2005 with a mean follow up of 24 months (9-62 months). The mean age was 51 years, 27 patients presented with radiculopathy, 15 patients with myelopathy, and eight patients with both. Clinical and functional outcomes were assessed by using Prolo scale, Japanese orthopaedic association (JOA) score, and Visual analogue scale (VAS). Prolo results were documented good to excellent in 43 (86%) of cases and poor in 7 (14%) of cases. Mean preoperative Prolo scale of 4.7 (SD 1.63) improved postoperatively to 8.22 (SD 2.12.) The average preoperative JOA score was 11.7 (SD 2.51) compared with 15.42 (SD 2.20) postoperatively with a mean recovery rate of 76.3%. VAS score improved from 6.65 (SD 1.77) to 1.76 (SD 2.40). All the results were statistically significant (p-value <0.0001).This study suggests that Plate cage Benezech implant is a safe and effective device for anterior cervical discectomy and interbody fusion.
