Objective : The authors investigate the effectiveness and the demerits of the AMSLUTM cervical cage used in cervical spinal fusion for correction of cervical degenerative disc disease.
Methods : A total of 19 patients with cervical degenerative disc disease underwent anterior microdiscectomy and the AMSLUTM cage fusion. We made a retrospective comparative analysis between cases using the AMSLUTM cage and the classical autogenous iliac crest graft(AICG) with plate fixation about operative time, blood loss and hospital stay. The patient´s neurological and functional outcomes were assessed on the basis of the modified Odom´s criteria.
Results : The use of the AMSLUTM cage was found to save operative time (mean, 15352min : P=0.004) and blood loss (mean, 236171 cc : P=0.032) as compared with the use of AICG. There was no donor-site complications and all patients were tolerable to ambulation at 1 day postoperatively. The patient´s clinical success rate was 89% on discharge and 84% at 6 months postoperatively.
Conclusion : The use cf the AMSLUTM cage provides several advantages : no donor-site complications, brief instrument procedures, short operative time, small amount of blood loss and satisfactory clinical success rate. But it also has many limitations : short follow up period, kyphotic change and subsidence. Further investigations and clinical applications are necessary to use AMSLUTM cage in cases of spondylolisthesis and traumatic cervical disease.
